MODULE 3 INTRO TO SUSTAINABLE DESIGN

hi and welcome to lecture 2 in this lecture we’re going to quantify sustainable design and we’re also going to give you a quick introduction to the lead rating system and i mean what i mean by quick is it’s just a quick over you overview of the of the system in this categories we won’t get into too much detail only to to say that there is an entire course in this program that is dedicated to the lead system and and you studying that system in greater detail so basically in our last or the first video lecture of this this course we basically justified sustainable design so in this lecture we’re going to quantify it and dive into it in greater detail of how we achieve sustainability in in various ways within within maybe the building design industry okay so I stated in our last lecture what is sustainable design so stainable design is sensitive design that use that looks at being design or working in an army with with climate and in response to climate it attempts to use natural solar and ventilation characteristics of the local climate environment to inform the building design so to minimize the use in dependency on consumptive nonrenewable energy sources and it looks at living lightly on the earth in order to minimize the use of non-renewable sources and also to minimize the impact on the environment both at a local level but also as at a global level I’d invite you to watch a quick video it’s a very interesting video it’s an interview with rob watson and rob was the is says is looked upon as the father of sustainability in the lead program as he was a founding member of the US Green Building Council so I will this the video has been spliced into this video lecture so you will you will be able to watch it and and in its entirety and I’ll jump back into the lectures and this D video ends buildings are literally the worst thing that humans do to the planet nothing consumes more energy nothing consumes more materials nothing consumes more drinking water and human beings spend up to ninety percent of their time indoors so if they’re getting sick from their environment in fact they’re getting sick from their indoor environment not their outdoor bar on some level even though the green building movement is almost 20 years old it’s like we’re still in kindergarten I think one of the thing that’s been so interesting is that we still don’t know a lot of what we don’t know and that’s because as we’ve become much more sophisticated we’ve learned about all of the challenges that we still face so I think what started out as sort of a naive largely technical approach to solving problems in the built environment now we understand that markets and incentives and more business type issues are very paramount to successfully delivering a green product to the market clearly lead has got a lot of market cachet for buildings and while Lee does not certify products obviously having products and lead buildings is is a good incentive I think as much as anything people are beginning to think about a legacy and leaving behind something greater than themselves and so I think the ability to say that I am doing something for the good of the plan for the good of the community it is going to be a significant driver that it says if up to this point has been sort of the me decades I think we’re thinking in larger terms of thinking about the larger community and sort of ourselves as humans as a species as opposed to you know businessperson government person

etc and the other thing I think that’s going to be significantly driving this is the increase in resource costs so energy is going through the roof water is going to be supremely expensive as we begin understanding the full price tag of toxins in the environment the price tag for removing those toxins either from our bodies or from the environment is going to be realized and the fact that a product does not have toxins that are being put into the environment that’s going to also convey significant value both from a legacy perspective but also from an economic perspective it’s sort of like you know every every River every ocean begins with a drop of rain and so it’s it’s the little actions it’s walking out of the room and turning off the lights it’s opting to walk to the corner store instead of driving it’s asking yourself do I really need to do this because at the end of the day as great as all the material and technical advances are it’s probably not going to be enough to get us to where we need to be to fully live in harmony with the planet particularly with our population at its current levels so we’re going to have to cultivate desires that are not quite as high as they used to be so if we cultivate if we cultivate simple desires then we’ll will be wealthy even if we have fewer things and I think behavior is going to be a big issue and it’s it’s it’s our reaction to the crisis that’s going to make a huge difference just a personal story was I grew up in Marin County during the very severe droughts of 75 and 76 they had to pump in water and the we were on 30 gallons a day okay and that is just bare bare bare bones but what the Marin municipal water district did that was so brilliant was they allowed us to bank the savings so instead of going to parties where people were talking about their latest raise or their Porsche or their big house everybody’s talking about how big their their water budget was and so saving and having a big leftover water budget became the you know the bragging rights and so I think the ability to quantify and reduce our environmental footprint I think that will be the kind of bragging rights in the future where we’re saying I am living more lightly on the planet than anyone else or as as lightly as I can and that’s going to be a source of pride down the road so that I think that’ll be a good development I think we spent a lot of time talking about doing well while doing good that’s sort of a mantra these days but I think what a company like serious material shows is that you can actually do better by doing good and doing well is good but in order to succeed in a competitive marketplace you in fact have to do better and so what we see our products that not only perform better economically but they perform better environmentally and they provide a better service so with with those three aces in the hole if you will the products coming out of serious materials I think are going to really change the landscape than in a lot of different areas the thing that I find very intriguing about serious materials is the materials obviously but really what what it is is more the approach the way of thinking differently and honestly this this transcends any particular material that could come out because it’s it’s that way of thinking that’s almost the infinitely renewable resource and that’s really what it’s going to take its reimagining materials reimagining services in the built environment that’s going to be the leadership play moving forward so serious materials is far more than the song its parts it’s it’s the creativity it’s the way of thinking that’s really going to make this company I think a model for the 21st century you so again as stated in our previous lecture the United Nation has defined sustainable development and it’s defining it as sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs so sustainability looks

at incorporating heightened practices of energy efficiency design but also takes a responsible attitude towards the use of materials resources and the relationship and use of the site to minimize impact on the environment so the five principles of environmental architecture healthier in interior environments energy efficiency ecological benign materials environmental form and just plain good design so therefore the main objectives of sustainable design or to produce energy efficient buildings minimize the use of non-renewable materials make buildings durable so that they last longer and therefore do not need to be replaced at an earlier time and therefore minimizing the use of further renewable sources and non-renewable sources by keeping the building in greater state of repair for a much longer time it also looks at minimizing greenhouse gas emissions and also looks at minimizing the negative impact on the site and on the environment so a lot of these points are going to be studied in a greater detail throughout the program and further in further detail even within this course especially on the design side design side of things where we will look at incorporating sustainability within the architectural or design development process so it’s it’s really not hard it does require some specific thought to designing a functional sustainable building but as this course what I will try this and to do in this course is to give you the necessary tools to make a sustainable building appealing and and also functional now you know sustainable buildings don’t have to look much different than normal buildings some cases they do a lot of the architects you know the more prominent architects tend to be a little bit radical with their sustainable sustainable buildings but it doesn’t mean that that’s the avenue that you need to pursue in this course if you need to or wish to stick to more traditional type buildings that sustainability can still be achieved quite successfully in in traditional architecture so again a couple of more videos that I’d like you to watch on the benefits of green building and like I said earlier they are spliced in to this video lecture so you can view them as as I go and I basically just keep going with the lecture as soon as the videos are done for a number of growing small firms going green and business starts with green construction in the United States buildings account for nearly forty percent of total energy use twelve percent of water consumption and thirty eight percent of carbon dioxide emissions four states and cities are adopting regulations that encourage or require small businesses to be green and energy-efficient I know that in other cities across the country there they are giving incentives to developers for example to to have leed-certified buildings and do green roofs and various other things the green movement has to take place on the local grassroots level and that if anything’s going to change if behavior is going to change building is going to change we need to really emphasize that on a local level so cities are really getting on board green buildings use thirty percent less energy on average than a standard building but do cost savings being a return on investment for green buildings well from a new construction standpoint all the data indicates that a new building doesn’t cost any more to make by using green technologies and that’s because of

the availability of new products that are environmentally responsible and the new technologies that really focus on energy savings from a retrofit environment you might spend a little bit of more money up front but at the end because of the energy savings and the energy efficiency there’s certainly a payback over the life of the building now a small business owner does not have to start from the ground floor to make green building improvements so understanding where your energy is being used and then taking steps to reduce it for example automating lighting and automating the temperature in the building so it’s not too hot in the summer or too cold in the winter has immediate economic benefit you’ll find more ways to make your small business operation more environmentally friendly on sbtv calm I’m grant review for sbtv calm or small business is our only business I think my first philosophy is be good for your solving can be good for the environment at the same time the house has built me as much as I built a house at one point I realized that the conventual house construction is all done without having the natural elements in mind what are the similarities between a modern house and a patient in intensive care they’re both on life support it’s exactly like that the water comes in pipes film outside electricity comes in pipes you know the house is not designed to take its energy from natural elements loss of nature they can be incorporated in a house design the way this whole house is designed and set up it’s it prioritizes the use of natural energies that are being harvested by the house itself and when they run out then automatically and seamlessly there’s the back of grid the power grid the water the heat anything that’s free is given priority and use first inside the house rather than having it pipe from a long ways away and at a great cost of our pocketbook and our environment it can be done it’s very simple actually you look at nature and then it’s all there and that’s the nice thing about it you know whether you want to change your lifestyle or not you can you can have a zero energy bill I tell you what I look at weather in such a completely different way if it snows outside it rains outside of wind blows is blistering off with the sun shining anytime I’m collecting something home building can be changed by this design because it makes a lot of sense first of all it makes 0 sense from people’s Independence point of view savings in the pocketbook I think is probably the main reason why people would do this in the future we don’t know where the energy prices are going to go and the Sun is always the same price so you can be good for your solving can be good for the environment at the same time and still live in a beautiful home that is the art of new house design and I think that’s where we going to go with our vision I think having built this house and as I said it built me as much as I built the house it’s impossible for me to now build a conventional house I would always want to incorporate these natural systems in the design and in the building off the house I would feel bad about doing anything different now that I’ve done this and now I know that it works fantastic and it’s a beautiful experience to live in a house like this it’s very good for the soul and healthy and you walk right into your greenhouse and you know that you gray water is recycled you know you collect water from the roof you collect the heat from the Sun when the wind blows your windmill is spinning and put some electricity in your battery it’s a it’s a wonderful thing you so as as the construction industry and designers are becoming more aware of the importance of the benefits of sustainable buildings there needed to be some tools in place to quantify

sustainable design so how do you how do you measure who says a building is green and how green is a building so there are so basically the industry has sort of become not regulated and in the sense that it’s it’s law to to design sustainably but they there there are several tools out there to quantify it and and to determine if a building is what level of sustainability of building has achieved so there are separate several separate bodies that govern sustainable design and you know I won’t run through the entire one here the entire list but the most prominent here in North America is called the lead system and it’s developed by the US Green Building Council and so we’re going to that’s the one we’re going to be concentrating on throughout this program and include including this course so so the lead assistant assessment system explores the various categories if you will to quantify sustainability so it basically what it does is that it created categories for a building and provided a rating system for each category and you score point four different categories and the end product basically the number of points that you’ve achieved provides you with a certain category of certification so the Leadership in Energy and Environmental Design that’s the definition of lead so it’s the green building rating system so it’s an assessment tool that has been designed to answer that question so it is currently being promoted throughout North America and it’s for the evaluation and promoting of sustainable design so its goal is to initiate and promote practices which limit the negative impact of buildings on the environment in the occupant as well so I’ve got here also a few more videos of of how the lead system works some marketing educational videos from the lead and basically a couple other videos not necessarily put out by by the green us bill green building council but good little videos that show that quantify or justify sustainable design I absolutely love being in this green home it just feels like a normal house it doesn’t it doesn’t feel like I’m having to compromise on anything in living in a green home there’s so many things that are so in the background that you don’t you don’t need to think about them I have so many people that I tell them about my home and they just they say the car I wish my home did that we didn’t buy this house because it was Green okay if we would ever look at another house one of the first things we would ask is it green quality comfort savings an investment in your family’s future green homes are becoming increasingly popular among American homeowners but how do you know it’s truly green if you see this lead logo you’ll know that your home is green this logo gives you the confidence that your new home has been built to take into account energy efficiency water efficiency practices that improve your indoor air quality all the things that taken together make for a truly green home the lead green rating system for homes developed by the US Green Building Council provides homeowners the benefits of green features in new and retrofitted homes and the added value of having an independent third-party verify that the home has actually been constructed with these features to do this leave begins with a list of must do’s mandatory requirements that set the floor so you can be confident that the home starts from a higher level of green then a road map offers a number of optional measures

that address a variety of green home features points are assigned tallying up all the features that work together to make your home even greener to earn LEED certification all the mandatory requirements plus a number of the optional measures must be successfully incorporated into the home and the more of these extra green features that are incorporated the higher your home’s level of certification let’s walk through the eight categories lead covers one of the ways your builder can optimize your green home is through a process called integrated design your builder gathers experts at the table early and throughout your home’s design in order to maximize the green benefits we refer to this category as innovation and design process getting the most by communicating early and often it also requires your builder to develop durability strategies to help make your home last and avoid common costly repairs did you know the average American spends 52 hours a year sitting in traffic that’s more than one week of potential family time exercise or even vacation where your home gets built in relation to existing community resources such as transit groceries daycare restaurants post offices places of worship infrastructure and more is one of the important ways you make your home and life greener lead for homes refers to this as location and linkages the location and linkages category also protects natural resources by keeping new homes away from places like endangered species habitat parkland and wetland building a home can have a large impact on the natural ecology of the land the sustainable sites category minimizes disturbance to the land promotes native landscaping and encourages housing density reducing the impact of your home water is critical in some parts of the u.s. water levels in underground aquifers have dropped more than 100 feet since the 1940s clean water is too precious to waste and typical new homes can easily conserve thirty percent of their water usage through efficiency measures the water efficiency category rewards homes for minimizing water use indoors and out through high-efficiency showers and toilets low water use landscaping and irrigation systems and the use of gray water and rainwater approximately twenty-two percent of the nation’s energy is used in the housing sector your home’s energy consumption has a large impact on your pocketbook and on foreign energy dependence the energy and atmosphere category requires a tested energy performance of your home that exceeds the 2004 international residential code by at least fifteen percent it also rewards saving more energy through a number of well-known building techniques and the use of renewable energy bottom line you’ll enjoy a more comfortable home in lower utility bills and at the same time help reduce our nation’s dependence on foreign energy and reduce the greenhouse gases that cause climate change environmentally friendly paints flooring and other finishes can be the most visible features of a new green home the materials and resources category rewards the use of better materials like low or zero voz paint which means fewer toxic fumes in the home and it rewards being more efficient overall using only what you need creating less waste and recycling as much as possible these are fundamental strategies for green homes the US environmental protection agency reports that indoor air is up to five times more polluted than outdoor air lead promotes a healthier indoors with points4 features in the indoor environmental quality category proper venting of appliances sealed fireplaces and other household infrastructure are key and carbon monoxide monitors can help you keep tabs on their success heating and air conditioning needs that are calculated properly rather than estimated by a rule of thumb as well as good air filters can affect both your energy use and your air quality a perfect example of where integrated design can really pay off when you buy a new car you receive an owner’s manual that tells you how to operate and maintain your investment the awareness and education category assures that you will receive a home owner’s manual detailing your home’s green features and the major systems maintenance information you will also receive a walk through training on the operation of your home so you’ll know how to keep everything at peak performance just like a car your home requires a kind of partnership to make sure you get the same level of green benefits down the line as you did when you moved in single family or multifamily affordable or market rate production or custom lead works for almost any home you’re in the market for in any architectural and interior style living in a green home is an important investment in the well-being of your family and the planet not to mention your pocketbook but with so much media and marketing out there about all things green how do you really

know what you’re getting lead is a nationally recognized and respected green home rating system for home owners who want to know that their home is designed and built to a higher level through third-party performance testing verification and certification lead serves as a meaningful way for buyers to have assurance of a home screen claims a home’s lead certificate will indicate its level either certified silver gold or platinum the more green measures implemented the higher the level giving you the peace of mind that your home provides a high level of green performance meaningful credible tested verified by an independent third party it’s amazing how quickly you forget that that’s not the way it used to be you just get used to it I like the idea of a third-party certification because i think the term green can be thrown around very easily I think it’s one thing for people to think that their home is green think that there may be positively contributing to their environment of their community and I think it’s another step up to be able to have that independent backing it’s not just some somebody some builder putting a sigh out and said you know here he relies green homes being LEED certified home at the platinum level I’m I know that my house is is doing everything that it can and is built and constructed in every way possible to help me and also to help our environment and that gets me thinking and along along the lines of what I’m doing for the greater good for the planet the energy bills are certainly the best part of the experience it’s a no-brainer well green building really is a whole systems approach to building or even remodeling your home or commercial building so it takes into account everything from site selection whether or not you’re choosing you know an infield site in the middle of a city or an old farm site out in the middle of the country all the way through to finish materials takes into account energy efficiency water efficiency and then what kind of non-toxic building materials you’re purchasing to put inside your home well natural built home is a retail store that focuses solely on safe and sustainable building products so natural built home carries everything from dual flush toilets to non-toxic paints cork flooring and insulation made out of recycled denim jeans well there’s quite a few benefits of green building on the home front some of the benefits are actually monetary and there’s a lot of cities across the country that have had green building programs for a long time and those homes actually resell for between five and ten percent more than a home that isn’t certified as green there are quite a few green attributes that you as a consumer can look for when you come into a store and those include recycled reused content sustainably grown products water conservation products products that would help you towards energy efficiency and locally produce products as well and that means that the post consumer recycled content is coming from a product that we’ve already used so it’s the bottles and cans that you leave out on your front stoop for the recycling man to pick up it’s something that’s already been formed into a product that we can form into a different product by usually using a lot less energy and water a rapidly renewable material is basically one that can be harvested in less than 10 years some examples of these would include cork natural linoleum bamboo all of these products have a life cycle of less than 10 years we as Americans can really conserve in our homes and make a huge impact on the amount of energy that the nation is consuming as a whole and so even in your home there’s really simple things that you can do to conserve on energy everybody kind of knows to change your incandescent light bulb from incandescent to cfl but you can even take that one step further and change your compact fluorescents to an LED light or light emitting diode an LED light uses many times less energy than even a compact fluorescent now if we can get products that are sourced within 500 miles of where they’re actually being used that’s considered local and the embodied energy and transportation energy that are required to bring those products to you is significantly less well water consumption is a really big

aspect of green building there’s only one percent of the water on the earth that’s actually potable or drinkable and literally Americans are flushing a huge percentage of that right down the toilet I’ll do a flush toilet is one really easy example of something that a homeowner can retrofit or put in to save a significant amounts of water as I mentioned before it’s really important as we’re building tighter and tighter more energy-efficient homes to be very aware of the products the finish materials that were putting into our homes you want to make sure that they are lo envio C or volatile organic compounds that they aren’t going to off gas or add any toxicity into your air that can contribute to poor indoor air quality so for carpets for example you want to look for low VOCs natural fibre wool jute or sisal carpets aren’t going to add to that poor indoor air quality the quality of the low and 0 v OC paints out there really make it so that you should never ever have to paint with toxic paint again we’ve really done all the legwork for homeowners to really choose products that are healthy non-toxic rapidly renewable made out of recycled materials and gather them all into one place so homeowners don’t have to do a whole lot of additional research on their own natura built home eco-friendly building materials that are safe for you and sustainable for your planet stop by our showroom at 40 20 minnehaha avenue in south Minneapolis but visit us on the web at nancy built home calm Jackie O’Neill I’m a middle-aged woman who just decided to try and make a difference and I thought okay well you know nobody has ever been able to prove whether or not you can do green at mainstream prices so I wanted to set out and prove or disprove it I think yeah she may have just called the office one day and started a conversation we started talking about philosophy and green buildings and next thing you know she decided that we should we’ll try to work together on this project for her then I started out researching and the more I researched the more I realized that it was more than just energy efficiency that was important it was water efficiency it was sustainable use of materials and the land and also healthy air quality the concept of a zero energy home is really a home that burns no fossil fuel or at the end of essentially a one-year period or every annual period has a zero balance 0 balance for electricity and ultimately zero balance for fossil fuel so I rethought the entire plan in the meantime I had met people from the US Green Building Council and was introduced in the lead program lead is a really good basic benchmarking system with this project of specifically what we tried to do is we we designed to a standard and then go through a pretty rigorous process where there’s energy modeling involved around the systems the owner of the project can ask their design team to design to these standards are ultimately to design to exceed those standards so we raised the bar of this project to hit on all of those goals and to do it at market rate I think the impact of this house if we all work together to share what what was learned by this house is that first and foremost there’s no reason to build the way that we’re building now and all of the reasons for doing the other kind of building before or that oh it costs too much money or you can’t get those materials those reasons have gone away part of the real goal for the project was to be able to demonstrate that these technologies off-the-shelf technologies are readily available for anybody to use with an existing home about one-third of the energy can typically be caused by air infiltration so if you can reduce that air infiltration you end up with a much more energy efficient shell this is a super insulated shell it was built out of structural insulated panels that are really thick and filled with foam and so once I heat or cool this house it it stays that way for a long time there’s very little infiltration when you look

at all the materials in this project all of them tend to be selected because they minimize the amount of toxic materials that’s brought into the interior environment which is incredibly important some of the shower heads in United use so much water the low-flow showerhead standard now is about 2.5 gallons per minute although most houses don’t even have that this one is 1.5 gallons per minute water consumption if you put on a point a 1.5 gallon per minute shower head you’re not just reducing the the water load by one gallon per minute you’re actually reducing the energy load as well because now you don’t have to heat that water this this project really gave us the understanding that all of these things are achievable so it’s very very educational beneficial i guess for us as a firm and as a team of designers I didn’t necessarily feel like a pioneer when I started out but since I built this house I I am absolutely amazed at how many people have wanted to come and see this house I’ve wanted to come and talk to me about how to do it what to do can you do it how much does it cost who does it etc it really is an amazing amount of interest at this point in time your energy homes are doable and they’re doable at a reasonable cost and that was actually part of Jackie’s mission was to make sure that we could we could prove that you so now we’re going to look at the various categories within the lead certification program again I’m only going to run through these quickly because there is an entire course within this program dedicated to really studying the lead categories in detail and and also preparing you for the necessary exams to become certified LEED certified building professionals so basically the five Khattak of the six categories are innovation in the design process sustainable sites water efficiency energy and atmosphere material resources and indoor environmental quality each one has a potential of points or maximum number of points that you can achieve in each category with energy and atmosphere being the highest at 17 and innovative design process and water efficiency by being the lowest at five points each there are two oh sorry three categories within the lead certification the lowest possible category is the lead silver with 39 33 to 38 points and totaling of all the categories there is also the gold certificate or certification category which is from 39 to 51 point and then there’s also a leed platinum which is projects with 52 credit points or more with this LEED Platinum being more difficult to achieve it’s there I she is a very limited number of LEED Platinum buildings that have been constructed the united states or canada gold is d is the most most common category that most designers or builders or developers strive for so sustainable sites twenty percent so it’s 14 out of 69 point so the the main areas of concern or the main issue is here with sustainable sites is is things like site selection access and site designed and this category looks at things like site erosion sediment

control maintaining natural green areas within the site also the development of stormwater management techniques is also included in this category and it deals with with anything you know in conserving a natural or pre-construction nature of the site as much as possible even after the building has been constructive so these are the different categories where you can achieve a point in or they range from site selection all the way down to light pollution reduction in each one is a awarded one point credit there’s also a required category which each of the main six categories all have minimum requirements and in this particular case it’s erosion and sediment control where it’s it’s required to even be looked at this or rated as far as the lead system is concerned so the erosion and sediment control is not something that you can decide to eliminate or not address it’s a requirement as opposed to the other ones are all optional in the sense that you can actually delete some of them too and still make become a lease certified building so just hear some sustainable cite examples there you know there’s a few search the the internet here you can you can find numerous numerous examples of sustainable sites some of sustainable features that can gain you some points or things like green roofs control site water and offset urban heat island effects so those are all things that that play into the site site category and here it’s the Vancouver public library that I’ve got a throne as an example here that has incorporated a green roof on it’s on the roof and gain some points for its lead certification retention ponds are another great way of obtaining some points because that what it does it’s a couple of things one it allows you to manage the stormwater of the property and keep it on the property and also as you will learn a little bit later on in site design or site design course is that ponds can also be used to help naturally cool the building and in the summer so they they are a sustainable alternative for for site design control control site water it also offset the the urban heat island effect by absorbing a lot of the heat that is generated from the site and can also be used with heating and air conditioning through a geothermal system things of that nature water efficiency is the next category it’s one of the smaller categories at seven percent five out of six to nine points and this section deals with landscaping wastewater treatment and water use reduction and and looks at things like living machines so the water efficiency category also looks at things like capturing rainwater and reusing it in a non potable water system can also include things like waterless urinals composting toilets and other forms of water efficient appliances and fixtures so only five categories here in in this get in or subcategories if you will in the water efficiency and they are basically water efficiency landscaping reduced consumption by fifty percent or no potable use or irrigation it gives

you an extra point now to achieve this of course you know you would have to get into planting some landscaping material that doesn’t require potable water or very little water to to survive so things like Assad for example when when when P wouldn’t allow you to obtain this credit in this particular category innovative water waste water technologies water use reductions twenty percent or thirty percent each gets you a point so here are some examples of water efficiency here so we have a sample here of a biofilter that was used in the CMC mhee healthy house here we have a living machine and we are going to look at the living machine in greater detail and one of the courses within this program energy and atmosphere another one of the sections at twenty-five percent or 17 out of 69 point includes three prerequisites and it’s f it’s a has to do with fundamental building system commissioning in minimum energy performance CFC reductions in the HVAC requirements and the prerequisites allow are followed by six credits for energy performance renewable energy and additional billing monitoring with a potential value of eight points so here they are so the the three prerequisites are fundamental building system commissioning minimum energy performance and CFC reduction there and then we’ve got six credits here of varying options that you can incorporate into into the system for example if you can incorporate a minimum of five percent of renewable energy you would get one point if you’re up to twenty percent then you would get three points ozone depletion measurement and verification into the systems and then also green power energy in the atmosphere the prior to the adoption of lead energy efficiency was the only motivation to improving design strategies it did it successfully in affecting an increased levels and insulation high efficiency ratings of appliances and tighter billing envelope so you know this balls back down to a system that I originally studied in my studies in architecture which was called the art 2000 home and basically the art 2000 home incorporated all of these three features into into the design process which ironically has now become the minimum standards for current billing codes so I studied architecture 80s in less than 20 years later the what we were learning as a energy-efficient home has now become the minimum standard so just to show you how things have changed in just 20 years as far as the sustainable or energy efficient movement has progressed along so energy and atmosphere things like orientation of the building shading devices natural ventilation passive gains are all examples that you can that can provide you some points within that category here we have some pictures of bc i drove in surrey bc which made use of some shading elements here over them at the windows have maximized southern exposure of the major glazing areas again here exterior shading areas Revenue Canada building insert BC so these are the sort of things that they’ve incorporated into this building materials and resources in nineteen percent 13 out of 69 points with 13 points generated in seven credits so this section is as only one

prerequisite and the credits focus on building rios waste management reuse recycling and certified materials so the prerequisite is storage and collection of recyclables and then the optional credits are listed here and varying categories the top three categories deal with reusing of building so obviously if you are building a brand-new home and on a native land where there’s there’s nothing there’s no buildings on the property you’re not renovating you obviously can’t qualify for these three credits and then we have a couple credits here for construction waste management and if you recycle or send a lot of materials to do recycling for recycling rather than just standard waste you can gain a couple of credits resource reuse we use of resources in a couple of points recycled content so if you incorporate recycled material within the building envelope or the new building you can gain some points local materials so if you use twenty percent of materials local sort of manufactured locally you can use a gain a point and a and things like there’s no extra category for locally harvested products rapidly renewable materials you can gain you another point and then certified wood can also gain you a point so material resource examples here so we’ve got the Lea Wow Center for Asian Studies at the University of British Columbia so lower Ned at low energy durable material so there was a lot of would incorporate so we use large Timbers in roof structure so these timbers were reused from somewhere else and also low site impact no destructions of local trees in the retained vegetation as you can see here’s some substantial pine trees very near the building so they were able to to don’t build this and build this building without the impacting local or the existing trees some more examples here of examples of a efficient use of materials and resources this particular building here avoided demolition of the building reused the concrete structure and used an energy efficient at double skin facade and exposed concrete for passive game so the show I Institute again at the University of British Columbia reused brick on the exterior reused large timber structures in the interior shown over here in this picture composite composting toilets and also natural ventilation so those were examples of points achieved about this building so again other examples here of material resources credits fly ash concrete was used in this particular building into our environmental quality 22% 15 out of 69 points it’s the largest category with two prerequisites and the this one here it basically measures the performance of the indoor air quality and and kind of gets a tasting to get a friend into consideration things like tobacco smoke control which in Canada here is a mute point as most public buildings are smoke-free in most provinces as opposed to the states where there a little bit lacking behind on tobacco grew tobacco laws but you know you you’re not always designing you won’t always be designing public buildings you will design your Shumate design a lot of private buildings so you know this could potentially gain you a point if you corporate these tobacco smoke control features so it looks at including ventilation carbon monoxide monitoring

low admittance materials controllability of systems thermal comfort daylight access you know crease daylight access to reduce energy consumption or electricity consumption through the use of lighting or electric lighting make better use of daylighting things like that nature can be all incorporated to gain some points in this particular category so here the categories here so the two prerequisites or minimum IAQ performance and the smoke test control than the different categories here range from carbon dioxide to ventilation effectiveness construction I AK IAQ of management plan Jane construction before occupancy low mints material has four khattak report point available points indoor chemical pollutants source control control ability of the system perimeter and non perimeter thermal comfort and then there’s a nash rea requirement here that has to be met in order to get this particular point and then permit monitoring system daylight’s and views so if they like this is that seventy-five percent of the space you can get in one point and if day lighting is used at many percent of the spaces then you can gain one extra point so here are some examples here of daylighting as you can see here you’ve got some substantial fenestration on the roof as with the end of the corridor here so it provides a lot of daylighting that minimizes the use of electric lighting so in this particular case you they’ve just got some accent lining along the sides to to compensate or to add to the day lighting in the building so again here are some more examples of daylighting here we have a national factory here that’s you know it’s got a lot of daylighting requires less electrical lighting so more examples of daylighting so the last category spell innovation and in design process and allows a building to obtain as many as four credits for innovation as well as a additional point including a LEED accredited accredited professional in the design process if you have a lead accredited professional involved in the design process you can get an extra point it can be also awarded to things like a life cycle analysis community development education of the occupants and things of that nature so here are the four five categories there are no prerequisites for this particular category and what you can achieve innovation and in design depending on what you’ve incorporated and then one extra point here for the credit accredited professional so here’s an example of innovative design process it’s the york university system here you can sort of not going to enter into here for too much detail here but it basically incorporated some innovative designs in the form of a ground source heat heat pump and also some major ventilation components here to maximize efficiency in the building so here’s some same details here that shows you how it performed or achieved some extra points with some of the features built into the building so we’re like I’m not spending too much time on this particular these particular size only because the next few slides we’re going to dive into these concepts of paths of solar heating and cooling within buildings or residential buildings of course but so we’re going to spend a lot more detail on some of these systems and how you can incorporate in an appropriate incorporate them into the design process so some of the main focal points in this in this course is we’re going to be in

this course and the program as well is we’re going to look at lead as the sort of benchmark for sustainability and how we can achieve sustainability through the lead system and to lead rate the lead rating system and and you’re going to study it in further detail in this course in other courses within the programs
