Title:ابهام زدایی از LEED ND

این وب‌کست فقط برای مشاهده در دسترس است، برای اعتبارات AICP CM قابل استفاده نیست. ۱۱-۳۰-۲۰۱۲ ارائه دهنده LEED ND راز زدایی: ملیسا واکرل این ارائه به بررسی مسائل محلی مربوط به LEED ND و نحوه رویکرد و اندازه گیری ابتکارات سیستم رتبه بندی برای کاهش تأثیر منطقه ای این مسائل می پردازد. یک نمای کلی از سیستم LEED ND شامل پیش نیازها و تأثیر آنها بر انتخاب محل پروژه ارائه خواهد شد. این جلسه در مورد مسائل خاصی که توسط LEED ND پرداخته شده است و چگونگی ارتباط اعتبارات فردی با موضوعات ذکر شده بحث خواهد شد.


قسمتي از متن فيلم: Okay they’re good to introduce first speaker and Melissa Walker E is the lead administrator on for projects and serves the project team manager on 20-plus additional lead projects she has taught numerous US GBC chapter workshops and training classes melissa serves as the project team manager on Alliance Town Center which

Was a pilot need in the project in Texas and currently serves on the lead and B Committee for the local us Pearson sustainability master’s degree in sustainability and development from Southern Methodist University here in Texas so with that Melissa I’ll let you take it away hi everybody I wanted to give you my

Apologies for the second prisoner Lee Hall developed this this program with me and he wasn’t able to make it today so I’m going to be giving his portion of the presentation he’s with sustainable sure specialized and lead for Neighborhood Development and weak home so bear with me for this

First portion of the program because it was developed by Lee and I know it but he does it much more smoothly than me so let’s just jump into it I’m from the back group I work in architecture and leave also as I mentioned develop this as well and we developed it in the

Conjunction with our local US she defeated North Texas chapter we are an education provider for us GBC this has AI a consumer education it’s all APA our learning objectives are to understand the basics of we’ve heard any be rating system recognized the driving the drivers of leed-nd and understand how

Lead and the measures both those driving issues so this is a quick overview for US GDP and leadership and Energy and Environmental Design rating system is developed by the US Green Building Council and implemented by the three building certification Institute the background of lead for India is started

Really developing in 1994 and developed through the pilot system of which both me and I have projects in North Texas so these projects did not get certified he decided not to go for the final certification the limestone Center projects that ever mentioned did get certified under the pilot for what’s

Called stage two and we’ll talk about the stages in a minute that’s that one will not see going after the stage three final certification that one so lead and here’s a little bit different than the typical usua lead systems because it was developed beyond just us QVC us UDP actually partnered with

Convert 20 urbanism and the National Resources Defense Chapel so this is a partnership of something just beyond the building and exposure that one building can have to a community impacts it and have to the community so it really reached out to these other two organizations to get input because they

Understood that that the national resources potential and the seeing you had specific ideas on how neighborhoods can be developed more sustainably artena Harmy can you speak up a total I can’t is that better okay yeah that’s good thank you do you need me to repeat anything that I

Just said um if they just say that your voice goes in and out sometime so just try and keep the volume up definitely will start about to everybody so the impact that seeing you and the National Resources Defense Council had on the system is basically looking at Smart Growth

New Urbanism and green building and these things is improvable to live it’s a quality of life so the benefits of that are happier and healthier communities better environment and a robust economy we just talked a little bit about the benefits of weed so typically what the lead rating system

Measures is five categories plus innovation and design and those are sustainable sites energy and atmosphere water efficiency and materials and resources and indoor environmental quality and so that’s basically what’s for Neighborhood Development of that is completely different category so you’re looking at smart location and linkage neighborhood pattern and design and

Green infrastructure and buildings they also do have the innovation and design credits as well now the rate the difference of the rating system is because it’s really looking at how the land is used what land is being used the fabric of the neighborhood so that it just doesn’t look at just the materials

Of the building just the makeup of the building it looks at the entire picture so the ratings that are developed for lead the Neighborhood Development as far as the points are the same point categories that are available for the typical lead for new construction or commercial interiors or any of the other

Rating systems so forty points to 49 points for certified 50 to 59 / silver sixty to seventy nine for gold and 80 to 110 for platinum the difference here is that there’s 12 prerequisites for the lead in be systems and the credit distribution is as such so you can see

That neighborhood the neighborhood pattern and design it’s actually 40% of the credits that are available so that’s really weighted towards that that CNU piece of the puzzle the way that the development is organized green infrastructure building is 26% and then smart location and linkage is 25% but

Those are pretty close to equal with innovation in five percent regional priority is going to be anything that it was identified specifically notable for a specific area so for example in North Texas we have water issues we haven’t had rain in about three months now so stormwater

Management may be something that we look at here or water efficiency so the three stages first submission are different than any other system as well book lead systems lipid design or construction but the stages for submission for lead and B are a bit different so one of the first

Stage is really just going to be a letter that the developer received in an effort to get their entitlement from the city but this is before they have any entitlement from the city you can go and just put kind of a conceptual plan together and submit it in the US GBC and

GDC I will certify that as a stage one stage two was going to be more like the design phase the middle where the the plan is more developed and the the construction could actually have already begun you can only only submit for this up to 75% constructed once it’s more

Than 75% constructed you have to skip and go to stage three so this is really just a design phase and making sure that every with the plan that you haven’t played well that will be able to be certified LEED indeed page three would be your final plaque and so construction

Is beyond semi five percent or 100 percent complete and your your final certification is awarded so like I said previously my project that I worked on was at stage two so we have a certificate that shows that we have an approved plan but we do not have a final

Plaque so I’m going to go through some of the voluntary credits here in a little bit prerequisite and the we’d indeed are very different from what you have in your typical lead rating system so it really looks at where are you locating your site and so we’re looking at it

Forward we’re looking at that it’s an insole site or an adjacency site so it’s not a green field that’s in an undeveloped area or surrounded by farmland so you have to make sure if you are in an outer lying area that you have to do some testing of soil and look at

Endangered species to make sure that you’re not building on an area that’s prime habitat or prime farmland and so with these it also looks at where you build it for your wetland so if you’re building close to a wetland you have to be able to mitigate how far you’re

Building from that wetland and you cannot impact that wetland except for very minor minor ways or a nature trail or something of that sort so when you’re looking at coastal development that really comes into play or also any kind of militant near a lake or a stream and

That’s actually one of the one of the problems that we came in that we encountered whenever he developed he was looking at his lead for Neighborhood Development Project Montgomery Farm which is an Allen Texas he actually wasn’t building very close to a creek but it was and he was mitigating it in

Other ways but it just wasn’t something that was meeting the prerequisite so other prerequisites would be the green certified building you have to have at least one certified building with another lead rating system you have to have minimum building in water efficiency which is very much like the

The other rating systems and then you have to have a trip plan or a future construction solution prevention plan which is going to be erosion control and sedimentation control and things like that you see in a typical system we rating system but there’s also some other interesting requisites

But by far the most onerous credits or purposes that we have in the North Texas area would be for density there’s a there’s a lot of land here and so a lot of developers really want to sprawl out and so with density we have to have at

Least 0.5 floor area ratio or 7 dwelling units per acre which can be relatively difficult in urban sprawl area but it’s very important for sustainable development because the more we saw obviously the more detail and the drivers behind that during a little bit so we talked a little bit about the

Basic contact development requirements aggressive with interesting is there’s a higher contact development for requisite for transit workers so it’s for building and a transit location next to a rail station or some things of that sort you have to have 12 units greater than a certain law systems of the site and you

Have to have anything further than I think it’s a half a mile you have to have seven units per acre and then for the non residential areas you have to have a point eight SAR as occurred to a point tribes and then you have to that’s

Again beyond that at half a mile walk system to the rail station garrison grants available for HUD that can help finance some of this there was a $25,000 grant given to a project here in Dallas just last year for VA hospital lead and B project development next to that you can get rating

Pricing depends on if you’re buying card coffee if you’re buying a digital if your us UDC member or not you can but you can download just the rating system which is the basic credit requirement for free at USC bc org so it’s really the the leading view system is designed

To for looking at financial incentive structural incentives for project to look at how you want to evaluate how you are planning your development beyond the typical city zoning but you really want to be familiar with that rates rating systems what is not supposed to do is replace typical plans and zoning that

You see based from your city it’s not supposed to replace any environmental regulation you know the epa or your local here we have the Texas Council of Environmental Quality so any kind of local state agency that’s going to provide over those environmental regulations is going to override

Obviously and then you can’t certify an existing neighborhood that’s already been developed and you can’t try to certify a town or a city as a leader to indie development so what are the issues behind leads on your development this is kind of the face of climate change

Cute little or acute big polar bear this is what everybody sees and you know the polar bears are endangered but but that’s so far away and it’s so distant in it so difficult to get your head around but basically there’s lots of things regionally that you can do in

Your area that are that it drives not just global climate change it doesn’t it doesn’t just drive you know what’s going on globally but it looks at how we’re losing using land locally and how to solve local issues so we buildings are great but we developments are better so

Here we have some LEED Platinum project and the image on the left is utility office and Michigan and basically this is a lady platinum building there’s wind turbines there’s automatic lighting controls there’s lots of great benefits of this building but the problem of it is that it’s not

Located nearby anything else so any employees that have to commute there are going to have to go far from home or you know or you know carpool or find other ways to get there and there’s also no fabric around it for you know what if you want to go have lunch at a

Restaurant or if you have a dry cleaner that’s nearby or you know any kind of a there are in some open space but it’s not really very well managed so this is a great building it has a lot of great benefit it doesn’t do item and then here

Are it might it’s a great home again great energy efficiency and wonderful attributes but it’s a very large home on a big site in a suburban neighborhood so there’s there’s some things that could be improved about that as well so what are the drivers behind the sustainable development movement this is where I

Focus this is really more of a regional issues so what I’ve done here is focused on our specific issues here in the North Texas region so what you see in this image is the north central Texas Council of Governments projections for Democrats demographic growth for population growth

And you can see that the inner inner ring suburb and the inner city you have some growth going on deepened downtown Dallas Fort Worth is over here and then we have this as the mid cities the DFW Airport is in this area but here you see the bulk of the growth is really

Projected and around the exurbs so this isn’t necessarily going to be the best movement for the dfw metroplex sir we’re actually in DFW looking to increase our population by five million people by 2030 so that’s about doubling our population I’m sorry growing our population by 50%

So one of the consequences of that is urban sprawl and what you have here on the left is a picture of this area on the right taken in 1940 so it’s basically a four-lane divided highway u.s. highway 75 and farmland all around so now what you see here is North Park

Center which is a large shopping center here this is a church and a cemetery and this is all housing and actually very dense housing we have a rail line going up here but you can see this actually used to be considered way out in the middle of nowhere

And in Dallas whenever it was first developing and now as part of the support of the city so the result of this is loss of habitat and oftentimes what we hear on the news here is whenever you have you heard about Bobcats and people’s neighborhoods and killing their smaller dogs and cats and

So there’s a reason why these kinds of things are happening because these these critters no longer have a place to go they don’t have a place to live and so they impact our our lives our lives but we’re impacting their more severely they also have the loss of prime farmland so

What happens with this is where we build our cities or where we have historically built our cities are around agricultural centers so where farmers would come and trade their goods at market well what happens whenever you build your cities up around those areas that the farmers would put the trade centers closest to

The net to the prime farmland and so now all this prime farmland has been developed so we’re losing prime farmland in the United States alarming rates along with habitat loss is going to be stormwater issues so where you had vegetation and trees and Prairie lands or even in farmland you’re getting

Amazing amounts of erosion and so you’re losing that topsoil as well that’s going to be beneficial to agriculture so this is a this is an image and I think it’s interesting because this is from a asphalt company in Colorado and they were very proud of this work basically what’s happening is there’s no

Infiltration of water it’s all running downstream and when water runs downstream you have issues so this is what can often happen when water runs downstream data without infiltration at it at a to fast pace so these are flash floods that we have here in Texas quite often and also in Central Texas region

This is actually close to the Brazos River in Central Texas and here we have very clay soil so there’s not a whole lot of infiltration anyway and whenever you’re you remove impervious or when you when you remove pervious surfaces and especially grasses and things like that that hold the water and infiltrate it

Down then you basically get flash floods there’s been a lot of instances here where people come to eroded into adjacent creeks there’s been instances where people have been washed away in creeks there was one instance incident where two young women were crossing a bridge in their car and the car was

Swept into a large Creek here in Dallas and one of the girls passed away so there’s definitely impacts to development in addition to the undeveloped areas that are that we’re losing so when we go out like this it’s not just that we build a building in a

Little of nowhere it’s that we have to build infrastructure to get there so it takes energy that takes time that takes effort it takes materials to build these this infrastructure so here we have road construction you will have to design for water and waste water obviously and so where we have stalling

Development we have to bring utilities out to those as well and again that takes a lot of effort it takes a lot of energy it takes a lot of materials which can be good because that’s job on the other hand there’s infrastructure needs and previously developed areas already serve where we have feeling

Infrastructure and so there’s a lot of jobs job opportunities there as well what’s interesting about the way that for all happens is that the city in a way in an effort to bring development to their community will pay for all this infrastructure so this is something that the developers basically get for free

And the cities and taxpayers have to bear the brunt of the car while the developers typically get so what happens whenever we build out and for all or what happens when we build out in the sprawl format is that we have massive auto bill centric development and so

What you see here is this is actually an image of in Antonio Texas but it really doesn’t have we’d be any city in the country it could be Kansas City it could be balanced it could be Sacramento it could be any of those places because it’s all

Basically centered or on the car and so it’s interesting about this as you see where do you see the person in this where do you see the human being walking down the street there’s no comfortable place to walk down the street in this and I remember going to a movie theater

It’s a redeveloped movie trip center here into a movie theater there’s a couple of stores that are down the way and basically it looks something like this and I remember we were waiting for our movie to begin and we were trying to see what the stores were just to go and we

Would walk up hostage or there would be no sign and those on the door there would be no sign in the window of what that store was you kind of don’t look in and see what sort of merchandise they had but in order to actually know what

The store was you had to walk out into the parking lot so there was no pedestrian sign inch whatsoever even for people who are waiting to see a movie and I’m sure that happens fairly commonly there so along with sprawl development and auto central Texas Council of Governments now that is the

Cost and impact areas of congestion in 2007 when this analysis was done at the annual cost of congestion was 2.2 billion dollars in that sense lost time infrastructure need wear and tear on vehicles and things like that and then you have the projected 2030 cost annual cost of congestion at six point five

Billion and you can see here where the congestion is increasing in these exurban areas and then also out in these outlying areas and so this is all based on spur development on for all development and so what’s happening here is the estimate on this is that there’s rail basically predicted everywhere here

So this is with increased public transportation but it’s still causing real problems with projected traffic session with traffic congestion from air quality issues talus force has actually been a non-attainment area for EPA air quality standards for many years now we’ve developed several plans and have implemented several plans to improve our

Air quality and they have improved however as our air quality becomes entertainment EPA increases the standards again because there’s always going to be a more amped up version of the best that can be or is oh good I guess the least toxic they’re willing to accept and again with that whenever you

Talk about the infrastructure infrastructure impact air quality as well because if you’re because if you’re building a concrete road you have to fire that bad cement and so the cement aspire typically in the same region which is crispa different local economy and good for not transporting materials

For a long way but at the same time you have the cement that’s being fired and more nitrous oxide and sodium oxide and carbon dioxide being emitted into the atmosphere at the same time something else that that impacts development is centralized power so if you have pure power

Centralized in system areas or in one location that the large but they coal fires or gasoline or compressed natural gas power company then there’s an eight percent a minimum eight percent lots of energy generation within just the transmission of that and so if we could find a way to be centralize our power

Where it’s where the demand is met we can also reap benefits for from using waste heat and waste energy at the same time another issue with decentralized power is that you have a target and assistance basically for any kind of attack with your attack or something

Like that that if you if you damage that centralized power location it will make a big impact on the grid another driving factor of the leased neighborhood development system is obesity rates too see here these are a we see rate basically the percentage of population that has body mass index index equal to

Or above 30 so that’s about 30 pounds overweight for typical 5 foot 4 person in 1990 there were there were no states with an obesity rate over 10 to 14 percent with it with a BMI over equal to or above 30 in 1999 you can see that

Many of these many of these southern states and middle question Midwestern states are increasing in obesity with 20 to 24 percent obesity rates at BMI above 30 in 2009 you can see the lone holdout of Colorado and that’s right that’s risen to 15 to 19 percent and you have

Many of these southern states with a body mass index above 30 these affect things like insurance rates that affect longevity it affects quality of life so this is often in some in some ways attributed to this automobile society that we have if we sit in our car center

Office sit in our car again and then go home and you know it’s just not conducive to our environments not conducive to getting out there and exercising so what are the solutions that we Dundee is proposing how is lead indeed measuring these things so first of all they define a neighborhood

Development as anything that’s going to be it can be any development that roughly 3 acres to 300 acres but it’s been used building single buildings to her neighborhood development is just a mixed use type of structure but it can be all commercial it can be all

Residential or it can be a mixed use the credit categories as you’ve mentioned before our smart location and linkage neighborhood pattern in in green construction technology and that again breaks back into the national resources different sample the Condors from the urbanism and the US GDP so what’s the most important thing when it

Comes to smart location and linkage of rotation location location and so basically to want to minimize the impact of new development and avoid sprawl in order to do that there’s a prerequisite for smart location we talked about that a little bit before but basically don’t build on a green build site you are

Allowed to build on the greenfield site if your building next to a transit corridor because there’s already been slated for development basically by the regional governing body you cannot build on imperiled species or ecological community so you need to preserve any habitat that’s critical habitat for species and you can get that information

Typically from any state wildlife agency you don’t want to build to destroy or disturb the natural hydrology habitat or biological diversity so you really don’t want to impact wetlands in water bodies what’s interesting is that millennium ecosystem assessment developed by the United Nations 50% or our wetlands and

Water bodies integrated in the more in North America by about 50% since 1950 and there’s a lot of services that these assisting wetlands and water bodies provide including stormwater management from surge protection water cleansing things like that so there’s a knock dock you mentioned recreation and spiritual well-being agricultural land

Conservation basically you can’t build on prime farmland because our farmlands like I said has been degrading at alarming rates across the country and especially is that in Texas we’ve lost huge amounts of agricultural farmland here in the last 10 to 20 years they didn’t want you to build on floodplain

Plans actually are very valuable when it comes to hive regional hydrology so that and also habitat it provides that protection from flash flooding and storm surges so that that area is off-limits for lead for Neighborhood Development getting into credit you can get credit for building in preferred locations so

If you have a location with high connectivity to to other uses and areas if you have a high priority location that’s been designated by local jurisdiction that is going to be been charted for redevelopment it could be a brownfield site or it could be mixed income development or a mixed use area

That is looking for redevelopment and infill sites you can get credit for building on an infill sites if you have a place for existing infrastructure that’s surrounded by existing development and you can get up to ten points for that so when you’re looking at a point that

Basic system you can get quite a lot of quite a lot of points just for this one one item and that’s designed on purpose so that the system encourages developers to build an infill sites rather than for all locations brownfield redevelopment there’s another area that that is

Promoted in the lead ND system so it you get up to two points if you build on an existing dedicated brownfield site and can clean the site and then build on it if it’s a high priority Brown additional point so let’s say that would be ETA designated Superfund site or something

Of that set or anything that perhaps impacts specific community like an underserved community another way that we did indeed measures sorry to interrupt there’s some um the standards that you’re going through right now to kind of relate it back to maybe the planning challenges that you experienced that Alliance town center or

Some how or how you achieved some of the points just a couple of examples well we didn’t achieve all of these points and the differences I will start doing that um the rating system has changed from the pilot so some of these points are a little bit different and if

I I don’t typically relate it back directly to what we did at Alliance oftentimes because some of the requirements have changed but I can I can do that as much as I possibly can I just yeah or any run from you yeah say that again or any of your other contexts

Just go on ahead okay great so pretty automobile dependence is is one aspect relate the lead MD system that if you reduce vehicle miles traveled then you can get up to seven points so one of the things we did at Town Center’s we had a lot of housing located to a job Center

So we had a we had a mixed use area surrounded by some highest highly dense housing and we’re also located along a transit corridor and so we could with the nearby housing we could reduce vehicle miles traveled based we did that Bay tansy the transit I forgot Gamzee

Stand for top of my head of course transportation management yeah there you go sorry about that another way you can get credit and how we Dundee measures reduce vehicle impact would be a bicycle Network and storage so this is different than your typical lead I’m going to put a buy some bicycle

Racks a shower or under development bicycle networks as minimum of three miles so we actually had a local bicycle network and for the Alliance Town Center that we were able to connect to we organized and designed bike lanes and have storage as prescribed in the weed

Envy system so what this does is it supports public health and it provides a way for people to get out and get moving in their day to day lives without having to get in their car and drive to work drive home and then go to the gym and we

Move additional times perhaps with our family housing and job truck sanity is another element where if you have a major employment center in a diversity diverse mix of uses you can get credit in the lead nd system this way it also promotes affordability so it links back to some other affordability credits in

The system this one we didn’t have enough job large enough job Center like an office part to achieve this credit float protection is another one that addresses natural hydrology and stormwater management but also protect habitats so this is if you have any any slope or grade above 15 degrees or 15

Now 15 to 15 to 45 degrees especially is what it measures but make sure that you don’t develop on those areas so that the motion control can happen in a natural way we didn’t have a lot of slope our site was very flat so it was not a

Credit that we could achieve or I think we got credit for it because he didn’t build on any slope you can also design for habitats or wetland and water body conservation so in addition to not impacting existing communities you can reconstruct habitats in the wetland and

You get credit for that you can also restore any impacted habitat or wetlands that you can get points for that as well and in addition to that you can dedicate that land for long term conservation so anything above 10 years and you have to be interesting about thing about that is

Well this is preserving perpetuity that actually has changed to have to be minimum of 10 years and that 10 years has to be funded so it’s not that you can you just say we’re going to you know conserve the natural habitat you have to actually be able to fund the the conservation of

That so natural land may take care of itself in the wilderness but whenever it’s development you have trash and things like that that impacted that you have to have to clean up and take care of we did not achieve we did not go for that one I don’t think it’s every single

Credit I’ll do my dad so for the way that the rating system looks at the organization of the development it’s really going to be looking at how that the traditional integrated development set up so basically that the congressman urbanism smart code is or smart book that is really what what we’re looking

At here so in texas a lot of people are afraid of density they don’t think they think of this as density you know downtown in areas that are tall skyscrapers that are packed full of people but we’re not necessarily talking about that we’re talking about this is

What this is not this is the New York type of density we also have just another connotation of them to be here in Dallas and the North Texas region is you have apartment dwelling so people think oh no I don’t want apartments in my backyard we don’t want we don’t want

To have this impact on our community you know and then you have even further you have a more dated apartment community and so maybe it’s got not necessarily that the type of people you want in your community because if the perception is that low-income people families live in

Apartment complexes and you know one low-income families near a space we have to have these segregated and such and so what we’re really looking at is a traditional Neighborhood Development and so we’re looking at no walkable areas this is actually in Maine this is another type of site that it

Would be well measured and least neighborhood developments and this has got street parking straight trees so got density with retail below office above this is actually Lawrence Kansas and then near and dear in close to home we have Granbury Texas again this is this traditional hometown city center where

You have civic spaces you have retail spaces there’s office so it’s just a mix of things with density and but not high density but this is just your hometown kind of identity in my hometown that I’m from is something like this as well so the conference of newer the urbanism is

Looking at is how do you organize development so that you have balance and so what they’ve done is they’ve look at this natural transect so you have a more dense air gathered back soon so this would be a beach base with nature’s natural transect and then you have a

Secondary dune which is a little less dense and then it’s the density tapers down until you have a natural area or in this one it would actually be another natural trend and so the way the development is broken down as you’re looking at basically any kind of hospital or entertainment districts or

Special districts you have an urban core where which is highly dense something like that first New York City area slide you have something that’s an intermediate density that would be you know that more Granberry hometown density so it’d be an urban center and then you’d just paper out to a mix of

Maybe more housing and with the retail and non-commercial flipped in and then you have a more suburban type of location that may be organized a little bit differently rural and then natural land and you can see how this correlate to those natural transects here it is a

Little bit bigger where you can see the density and I’m sure what the APA you guys are all pretty much familiar with that so I don’t want well I’m not too long but here you have a comparison of typical suburban development and a new urban s development and so what you have

Is there’s the same number of residences and businesses on the left side is on the right side however the right side the right side is organized much more efficiently than the left even though the residences are the same square footage and the same number but here you could have grandmother and grandfather

Living in this house right here and their grandkids living here in this house and in order to get to their grandkids because they’d have to cross the creek they’d have to get in their car drive to the main road again to another arterial road back down and then enter their

Neighboring development and then visit their grandchildren but here you could say what you can have your grandparents living here and your grandkids living here which is actually further away physically than these two but they could get walk or they could ride a bike or take a wheelchair and go from one to the

Other very easily and vice versa what’s happening here also is you’re preserving a lot more land so you have a lot more stormwater management you have a lot more native space you could have urban agriculture any kind of any other uses of that land but it’s just so much more

Efficient than what we what we toda belapur typically you want pedestrian oriented development this is actually a walking school bus which I thought was a lot of fun again way to get out and get moving on your day to day basis without yet to get that exercise without having

To go to a gym or do something special we’re looking at multimodal transportation different ways to calm traffic rather than just having five lane road and people haven’t signed that says 30 miles an hour so these are typical traffic calming method we want treat treat are going to be another

Benefit was interesting about street trees is that there’s actually a when you walk down a street that has street trees that has higher density here and straight trees if you think about when you walk into a parking lot or what walking into a big-box store you parked your car and you walk through

A big blank and see or open parking lot and they have a lot of cars but it’s not necessarily that that safe feeling that you might have if you’re walking down the street with a building and a tree and you don’t feel like somebody’s going to turn on you over it’s going to

Measure access to jobs and services so make sure the people are living and working and nearby areas also Civic spaces you want to be able to accommodate physics faces you want to have services nearby so restaurant grocery stores hardware stores you want to have a diverse uses of faces in the

Development so that you can do a lot of things nearby without having to to get in your car and drive or without having to drive long distances so something else for looking at what kind of housing we have it’s not all single-family housing it’s not all commercial or apartment housing you want

It measures the different diversity of housing stock so you want to have housing that that is good for all ages for all income so one of the things you’re looking at is allow for single-family homes you might want to have a type that would be a larger single-family home and then maybe a

Smaller home with less yard for somebody who may be retiring or or some place for people to move young couples without kids or who don’t want to have a yard any because coming out of high school going into college a diversity of people a diversity of housing and giving people

Choices so that if a family that’s a family with two kids the kids move away the parents want to retire and move into a different type of space so the kids want to move out and move into an apartment they don’t have to move to the

Next town they can live they can still live near their parents or you know if you have retired grandparents you can you can take care of them within the same community instead of having to go to completely different communities you want pedestrian oriented houses a lot of

Times you can have front porches that gives you a connection to your community so you can have that your own space that’s private but you can still get to know your neighbors you know there’s nothing that’s welcoming about this image that’s on the lower right hand corner it’s cold is detached but here

It’s warm that you also have shading elements so when you have a front porch you can have the window shaded so you use a solar heat gain and I meant where that’s beneficial you want to promote open space so again here Wilson is biologists who have studied the

Connection between the human psyche and connection to happiness that a connection to open spaces and nature and have urban garden that teach people to grow their own food that grows food locally these are children that where their food comes from also getting credit for redeveloping suburban locations you can

Do a lot of a lot of inspirational things a lot of a lot of beneficial things with existing infrastructure so that you don’t have to build out you can build up or around where you where you live design guidelines are something that that the lead in these system references

So this would be here’s your form based code and it definitely looks at the transect of the streets so you have that section of the street and how it impacts with street trees parking pedestrians looks the building height to width ratio or building street building height treatment price ratio so it credits

Diverse use of space mixed-use development centers so how does the system measure these things because definitely find some important so I’m gonna have to rush through this real quick I think we’re getting short on time so neighborhood pattern and development compact walkable environments you want in vibrant neighborhoods with Nate with

With Alliance town center we had a kind of a mixed-use center of the community that had lots of had a hotel it had residence and had retail it had some residential office space so it was very diverse very rich in mixed-use and then surrounding that was a diverse type of

Housing and so and it was all connected with bike lanes and sidewalks and street trees so you have a prerequisite for walkable streets which is basically to promote walking to make sure that you have an open community that’s not dated to support public health and things like that contact development we already talked

About that prerequisite where you have to have an average density that’s above a certain level community so you have to have a high level of connectivity and what this is looking at is not necessarily the type of stations you have but you want to connect to the outside community so in like your

Typical where I showed that other image with the grandparents you have to drive to their kids grandkids house which is across the creek you want to be able to have connections to different communities so it is open and that other people the people who are surrounding feel that they’re part you also get

Credit for walkable streets and this is actually the credit that you get the most points where you get 12 points for walkable streets so this it’s really encouraging developers and project teams to look at the fabric of the system and not just look at where it’s located or

What materials are want to support Public Health and a sense of community you can additional points up to six points for contact development whatever we really struggled at first with this in the lion Town Center because it is a somewhat exurban location is but it is a

Long transit corridor and it sort of sits adjacent to the Alliance Airport which is north of Fort Worth Texas and so we really did struggle trying to get that especially the non-residential density because if there is a level of more cost whenever you have to build parking garages and build up rather than

Out and so we Turtles with the balance of the density versus the attraction of new retailers and new commercial tenants we also had a lot of when it came to housing and so I think we had like 24 dwelling units per acre for housing so that we had it we had a

Wide range of types of housing that were there to to towns but it was mostly townhomes um mixed use neighborhood turns we did have annex news neighborhood center that clusters that land uses in one area and encourages people to to come to walk from their homes or ride their bike from

Their home to do different errand mixed in terms of verse communities we actually did have an element of this at Alliance Town Center it was a little bit different credit back then it was put into rental and for sale housing and we did ours I think mostly in the rental

Area but this basically measures your affordability against average median income and you have a certain percentage of housing that is designed for and sold at specific rate either 85 percent of ami or even 100 220 percent of average median income you get credit for reducing your parking footprint so if

You get credit for building parking decks for building surface Lots that are less than 2 acres again encouraging physical activity so that you don’t have a large bath parking lot that is again uncomfortable to walk so you can get credit for having a stress dense street grid net’ network so this is basically

Counting intersections and so these intersections here would not this intersection would count that these intersections here would not because there’s no outlets any other locations you get credit for having transit facilities that are covered and lit so you have a dry place to wait for the bus

Or the train like to have bicycle storage we did not have public transportation they were working on it with the city of Fort Worth to get better eats to Alliance but it hadn’t been finalized and I still think it’s up in the air on that one the interesting thing about read about that

Alliance town center is that we were doing the map to make that ogre of the design and development planning in 2006 and 2007 and then into 2008 so when 2008 that when the economy crashed in 2008 it really just put the brakes on our development the way went through with

The certification the way we had it design but the reason one of the reasons we’re not going for that stage phase certification is because the development is changing a lot it has picked back up a little bit the last year or so but it’s not going to be exactly what we had

Designed previously you can get up to two points for transportation demand management again reducing your vehicle miles traveled based on your tansy you can have credit for access to civic and public spaces a lot of times Civic spaces are excluded from the rating system from from commercial development

So he could spread it for including those areas you also get credit for parks and recreational facilities we had some of those at Alliance Center using you credit for disability and universal design so we did not get this one we didn’t design our residences basically for for accessibility we did have good

Visibility however when it came to security and access to parks and things like that you get credit for community outreach and involvement this is one that’s really interesting we thought we were going to get this on Alliance Town Center but we didn’t have we haven’t documents at our meetings that we had

Well enough so it didn’t really come true for us but basically this is going back to the community and saying what did you want how do how can we serve your needs so that you’re not excluding or trying to relocate you went to work in community within communities that are there and invite

Them into the process and hopefully improve the fabric of your of your development that way local food production you get a credit for that one point again teaching kids how to grow up how to grow food and where this would come from salsa’s community based agriculture you

Get credit for street trees you did get this one on Alliance Town Center she also gets credit for putting in a school because again a lot of times schools are excluded from the way it’s developers will develop a community so it encourages walking to school and having

A walkable way to get to school and having a school within your community so I’m gonna I know we’re getting short on time the the last little bit is infrastructure improvements integrated infrastructure based on the traditional US GDP lead guidelines so this is a lot of what has been developed in present a

Lot so it probably won’t be really anything different than your typical lead system stormwater management it’s something that’s an issue is measured very well if we didn’t be this is a community where we don’t have where we don’t have curbs so the runoff going into the park area and some oil some

Wastewater management areas you have surfaces that are pervious for ability heat island reduction basically reducing that so we’re hitting on your buildings you can use and end on your site so you can use pavers and I albedo material to be you can have looks at the strip distributed energy it measures the loss

Of those those lines the transmission losses incur district heating and cooling so locating co-locating energy generation and using any waste heat to to heat or cool a building and so how does lead measure some of these items you have to have if you want to basically improve energy efficiency improve water efficiency with

A waste management and reduce the impact of construction and operation so for the prerequisites we have to have at least one building that is we’ve certified we had to have an average efficiency of 10% over ashley 90.1 2007 and you also have to have a minimum water efficiency over

۲۰% of a baseline and so those are difficult of your green building systems and then for construction activity you have to have an erosion and sedimentation control plan that’s again in line with the typical lead systems and those are your infrastructure per episodes then you get credit for any

Additional certified buildings up to five points and you also get credits for have 80 90 percent of your building stock with high energy efficiency up to two points no what’s interesting about that is your typical lead system will have 19 points for energy efficiency whereas this one is 2 but you have 12

Points for for walkability and 7 points for density so you’re looking at those different credit weddings rate waiting in the rating system you get credit for roots in your water reviews over 40% again just one point as opposed to 6 4 or 5 and the typical system you get

Credit for reducing your landscape irrigation needs by 50% you get credit for building reuse and adaptive reuse and you get additional credit for historic preservation of buildings art is about development lanskoy Alliance Town Center was ground up all new so we didn’t have any of these opportunities

On that one we did get the water use reduction and LEED certified buildings I think we got three or four points for LEED certified buildings on that project you also get credit for minimizing side disturbance and basically preserving heritage and champion trees so you don’t

Want to go you don’t want to have a lot of staging beyond what you’re going to build you don’t impact these natural spaces but you also make sure that you have quality tree canopy is going to be preserved we had basically a open site so that wasn’t relevant for our we did

Get credit for points for stormwater management so if you reduce by forty percent over a baseline you can improve your improve your rating at that point as well you get credit for heat island reduction we achieved it that town center is actually relatively easy solar orientation so this is looking at if

You’re orienting your sights on or your flats on an east-west axis versus an off stop access so you get credit for east south east west and this is something that’s not really measured in any other other a belief system you get credit for distributed energy so on-site renewable

Energy you can do biomass hydrocele small scale hydro photovoltaic winds any of these and Dallas we actually have an opportunity for active geothermal I know that most of that is in Northern California but we have some engineers with who team up with the Southern Methodist University who are trying to

Look at opportunities for distributed to your thermal energy here in the Metroplex which I think that’s a really interesting proposition up to tree points on that one we talked to them about that for Alliance Town Center but it just wasn’t quite there yet you get credit for district heating and cooling

And you get credit for infrastructure energy efficiency so if you have energy-efficient light fixtures and stop stop lights and things like that and you get get point a point to that and we did achieve that with our lighting and energy and Design at salient Johnson you get credit wastewater management so if you’re

Cleaning your weight rates water wastewater to put about standard then or if you divert it to a 50% Norway sweater you can you can get credit there we did not go to that one Hanoi own Center you also get credit for specifying and including recycle content in your infrastructure in relation conjurus way

So we were able to we are able to achieve that at buoyant town center as well and you also get a point for light pollution reduction so you preserve the night sky and that helps with migrating birds it helps with spiritual and recreational because you can have that

Access so we were able to achieve that in the morning John Center as well we just made sure that we reduce our lighting power density we looked at our photometric and made sure that we didn’t have over we worked over lit in certain areas and that we also looked at full

Cutoff light fixtures so we didn’t have light filling into the night sky which is more wasteful anyway it’s not as efficient to push the light into the sky whenever you really want to light what’s on the ground also get up to five points for innovation and design and you get a

Point for a LEED accredited professional and so we got we got two of the at that point it was only for ID credit things all at the point for ability definitive professional regional priority basically and we talked about that a little bit you you get credit for things that items

That are picture area so here in Dallas you have a lot of brownfield so that might be a regional clarity credit here it’s based on based on analysis that was done by committee and that’s it so resources that I like to look at I’m sure that American spending association

Has smart code down and we also have a lot of municipalities or metropolitan regions have their own Council of Governments easy bill the web search for the reference Center for Disease Control’s urban land institute the contractor and urbanism US Green Building Council the National Renewable Energy Lab and a fun one for

People to put their address to get in and walk for calm and so you can put your address in and see how walked all of your neighborhood is it’s on a1 and seeing the lowest and 100 being the highest and it’s a lot of fun so my contact information is melissa wacker

Liat becker calm if i don’t get your question and you want to ask additional questions and feel free to email me so abre we have any questions yes we have several questions if you could just start off we understand as planners that there’s this rating system out there

That you can earn points for specific development but is there some sort of overarching document that’s out there that can maybe help us with the regulatory side of things to encourage these standards or to may be require them is there any sort of document out there like that there actually is a

Document that developed by the US GBC that is a guideline to encouraging municipalities to make it more developer-friendly with codes and standards and zoning so the US GBC does have a document that that is a guide for cities to implement some of these initiatives so if whoever asked that

Wants to send me an email I can as having I’d be happy to send a link to the guideline okay is that on the US BBC website it is on the US CDC website it should be under I think lead rating systems and then leave for neighborhood developments and there’s probably an

Area that resources or something about it okay also see we have a lot is that can you go into kind of the background behind why lead and B certification for a building or for development would be important to us as planners the overarching kind of background why we

Were created we was really created as a measurement tool to really the the same reason the lead for new construction rating system was was developed is kind of a benchmarking system for development so that cities or I know Enterprise Community Foundation has a way to measure the sustainability of areas but

It’s just a measure of what’s actually done the third-party certification that they you know are we really green how green are we really so it would be really for marketing to to show people that yes our community was sincere and successful at developing a green rating a green development looking at

Incentives you can get incentives oftentimes with grants and such which she talked about early on so there’s a few different reasons to certify for indeed some people just like to use them as guidelines the difference between that is you know it’s different to use that as a guideline and with certain

Certification because you don’t necessarily have that that check and balance of what was planned versus what was implemented okay um we we have several people interested in how to become a LEED AP and be certified planner and I provided the link on the question panel but can you kind of talk

About that just for a minute about how to get certified as a planner there’s basically a tiered system to becoming a LEED accredited professional you have to first start with the green associate so there’s basically a testing format so there’s a pair of testing to the green associate

Which is your basic weed skills and knowledge and then you go into what’s called a specialty exam and so you would apply to take the Green Associate exam and then you would apply take the specialty exam and so the specialty you would select then would be the Neighborhood Development specialty you

Can take those tests at the same time so you could take one and then the Green Associate and then right at the same time take the specialty or you can take the Green Associate and then have some time in between and take the specialty and then have that lead in the

Accreditation so at that point you would have a certain amount of continuing continuing education requirements that you have to keep up as well some of them would be LEED specific and some of them could be just subject related okay and we have the gentleman an engineer who

Has passed me Green Associate exam but is looking for kind of an experience to experience a LEED AP and B project or however you say it and is actually made looking at the project experience yeah is there some way you can find that on the internet somewhere or you just have

To dig you know one thing about leed-nd is it hasn’t been adopted as commonly as LEED for new construction right now I think mostly because the development market is still pretty depressed I would probably contact my local US Green Building Council chapter and see if they have any rest shortly dandy project or

You could reach out to the lead in the team with us GBC to see if they know of any opportunities that might exist for a learning process maybe practice with documenting credits for and integrating with lead online system or something to that effect but probably

Your local US GBC or there is read in the pink contact email address on the US GBC website they have a they have a development team with us GBC that’s actually very responsive okay and how is lead and be different from need AP they’re just confusing it is confusing

So is a defunct term where what we call legacy LEED AP is just kind of a catch-all phrase LEED AP is a catch-all phrase between GA specialty and what we call legacy who are people who tested prior to 2009 when the system changed to be to follow the

ISO standards so basically a LEED AP is anybody who has that lead accreditation now what you have is a LEED Green Associate or a lead with specialty so I am a lead with two special lead a P with two specialties so I have a specialty in building designing construction and I

Have a specialty and Neighborhood Development so that’s two different accreditations that I have to maintain continuing education for so what you would say is on my business card it says LEED AP C D plus C or B DN C and then it says LEED AP pertinence as indeed well

So you would say you would say lead CDP D&C or lead and D so and there’s guidelines on the USG DC’s website or the GBC eyes website that will give you the the best way to document that on your business Parker there’s lightning materials add that to a ICP and you

Could get the whole alphabet oh yeah I got alphabet soup okay we have a person with a slide when you’re talking about BMI and age in because but it looks based on the chart that the population ages or as the population ages it gains weight in that

There is a shift to the south and southwest and the question is doesn’t doesn’t that relate to the movement and aging of the population or can kind of I don’t know how that that CDC study and analyze the populate the aging population let me see if I can find that

As my real happy it’s there and it’s been a while since I’ve read that study so I don’t remember exactly how it was looking at the aging population if it was just looking at that other demographic of the obesity but if you but there’s also a matter of for a long

Time before 1990 let’s say we also had elderly people and they weren’t living as long but I would imagine that he would have a benefit of exercise to improve longevity as well and fortunately I can’t keep an extreme detail to the CDC study I know it’s been

Updated I think in the last year or two okay there’s a kind of an easy one what you I know it was a pilot project but did you what we’d certification level was given to the project that you worked on in Alliance Town Center a couple of

Points away or excuse me but we were only able to achieve certified nothing which was you know there’s kind of a few questions about maybe maybe the process of definition it did a one-step process to set process that sort of thing it depends on if you’re going if you’re

Going to go for stage 1 stage 2 and stage 3 then you’re going to submit for review three times but let’s say you’re just going for one stage is prepare your documentation submitted to the GBC I and us GBC and then the the GBC I who reviews it they would review it then

Provide comments on additional information they’re looking for or any revisions they think need to be made you wouldn’t respond to the clarifications submit those clarifications to the review body and then you would achieve would receive your final certification so they would show whichever credits were approved or

Denied if any were denied and then they would get your final certification okay um if a local government requires a particular standard that also coincides with getting points does that negate the point or do you so since on examples water recharge requirement dark sky ordinances that sort of thing do you

Still get the points even if it’s required by a local government yes so if you if you build in a city that requires those things and they’re gonna encourage that for sure okay and also the presentation will be online so you can look for it then I think it’s on

The Ohio APA website is that correct oh it’s the UTEP uh I’ll send it to everyone on chat heard the minimum density requirement of at least seven drawing units per acre is the minimum requirement calculated using gross density or net density I guess just a density question are you familiar with

How to tackle a density for the requirement I know how to calculate into for the requirements I think I just don’t know you’re talking about dwelling units per acre about net vs. gross because what we did was we really just looked at how many how many we had not

Necessarily how many were occupied between net and gross so how many are provide okay um and I guess there are a couple of folks asking about different types of credits to 5 cm credits for a ITP they’re asking about AIA credits and we’d credit is there any way to apply

For those I’m not familiar it’s just this presentation is approved for us GBC and AIA I don’t know quite how that works through the American Planning Association the APA so that would be more of a questions for Ben okay well let Ben think about I’m sorry I

Apologize got that on we’re just gonna go through a couple more sure what this is a constant struggle with planners and engineering departments and whatnot but the question is what maintenance plans are out there for trees as part of the streetscape emplaced in the sidewalk what is the

Cost of maintenance eventually the trees will grow out of their location has it been addressed that hasn’t really been addressed by the week for Neighborhood Development system yes kind of the whole league they do have the requirement as street trees every 40 feet so I guess maybe the

Spacing has taken that into internal part into consideration but as far as how to fund maintenance of those trees and how to evaluate the impact of their growth patterns I don’t know that that’s been addressed by leed-nd okay I are I don’t I’m pretty sure okay

Um you know there’s this kind of some broad concept that you presented and obviously we only have a short amount of time but it was the look at we’d do specifically to address issues of place identity and that sort of thing well it measures those kinds of things first of

All in crediting preserving existing structures and historical the historical building and it also looked measures community involvement so if if you have an existing community that you want to preserve and you can have a meeting and review analysis different there’s all kinds of different things you can do to

Involve the community and so I think that those are probably the two most prominent ways that addresses the sense of place as far as the community that exists there already otherwise it in credit you for building on existing infrastructure and in infill site so that’s kind of maybe not as

Related as those other two okay um let’s see there’s some real specific questions about different standards but how do you demonstrate water use reduction on a project basis before buildings have been designed and built thank you scenario with power yeah you’re basically looking at specifying standards so you’re going to coordinate

Standards of flush and flow rates with the design team so it might it’s probably going to be more like a guideline I know that at Alliance Town Center we did have guideline requirements for what buildings would what what buildings would be like so you have guidelines for your site you’d have

Guidelines for your building you’d have you know basically we had we had law for those things okay um how does lead in the relate to existing neighborhood can you go back retroactively Lee and you cannot yeah there’s that’s been addressed that if you have an existing neighborhood and

You just want to measure that existing neighborhoods and it doesn’t relate it doesn’t if they won’t they will take that into account but if you have and draw your boundaries so that it includes the neighborhood so if you have let’s say a new development within that neighborhood you can expand it to

Include it and maybe last one because we could just go on forever do you give credit to buildings capturing or using natural wind breezes by using wind catchers or ventilation system this one this systems is not because it is a developed it to develop in basis

And I know that those things do relate and how you organize your development to accommodate prevailing winds but probably what you could do with that one is include that in an innovation and design point so that you can save that you you organized your development to

The to such a manner that it holds prevailing winds through and enhances the natural ventilation of your buildings I think that that would be a very strong innovation credit ok I guess that’s it guys thank you for attending then that’s it thank you for the presentation

All right thank you for those of you who are still in attendance oh ma I want to thank everyone and I just want to go through a few reminders first off to log your same credits for attending today’s webcast please go to planning the org /cm select today’s date and then select

Today’s webcast this webcast is available for 1.5 CM credit and also recording today’s session so you’ll be able to find the recording on youtube.com slash planning webcast and also utah api org slash webcast archive alright thank you
