High-income cities have an ecological footprint—the dispersed area of land and water required to supply their needs and assimilate their wastes—that is several hundred times larger than their political areas.‖ Scientific American, Building More Sustainable Cities, William E. Rees, March 12, 2009 U.S. uses 20% of all energy in the world. US population is only 4.4% of the world’s. U.S. uses 8% of all energy in the world just for our buildings!

Editor's Notes
- Hello, I’m Marc Harary. I’m an architect and alumnus of New Rochelle High School. I’m going to speak to you this morning about Green Architecture. This is how sustainability is applied to the man-made environment that people live and work in. Before I begin I would just like to thank Mr. Conneta, Ms. Kent, Ms. Chemelli, and Mr. Gardner for inviting me to give this presentation. I think this sustainability day is a fantastic idea.I don’t want you to leave this talk with just a bunch of facts and statistics. In this 30 minute discussion, I would like you to see and understand that there is a process to design. Armed with this insight, as you continue your studies, I hope that you’ll continue to educate yourself about what green architecture is and how you can take action to put in place green architecture as users and future clients of our built environment.Here are the main topics that I will cover in this talk:What is Architecture?What is Green Architecture?How are biologic systems similar to buildings?Examples of Green ArchitectureHow do Green Building Rating Systems work?What are some green features of the Lehman College New Science Facility in the Bronx. This is the project that I am currently working on?
- I thought that before we jump into Green Architecture, I would step back for a minute and discuss briefly what is architecture and engineering. This will help explain how architects can incorporate green building principals into the life of a project, from inception to construction.
- Does anyone know what “Green Architecture” is?Here is a quote that I got from a website, which I think it pretty good:“Green architecture, or green design, is an approach to building that minimizes harmful effects on human health and the environment. The "green" architect or designer attempts to safeguard air, water, and earth by choosing eco-friendly building materials and construction practices.”**http://architecture.about.com/od/greenconcepts/g/green.htm
- This diagram shows the process of how we use buildings. We’re at the center. We’re the reason buildings exist in the first place. We use energy and materials to support our bodies and activities while inside the building. The building must get it’s energy and materials from somewhere. That somewhere is the infrastructure. It can either be fixed – like a pipe under the street to your house, or it can be mobile, like a garbage truck hauling trash.Does anyone want to give me some examples of infrastructure?Incoming Electrical Grid Natural Gas OilFresh (domestic) water Steam (in Manhattan)Outgoing Sewage (human waste combined with water) TrashStorm Water (water captured by buildings and paved surfaces during heavy rain storms)The infrastructure has to get it’s stuff from somewhere and that obviously is the environment. How efficiently and sanely we design buildings, telegraphs out and ultimately has an effect on how much of a load we put on the environment. Sustainable design helps us reduce that load. One of the main goals of green architecture is to reduce, reuse and recycle energy and materials at the level of the building and the occupant.
- This chart shows how buildings impact other parts of our infrastructure.
- In understanding how a building interacts with the environment, I find it helpful to think about how a building is similar to our bodies. Modern architecture and engineering have given buildings many of the same capabilities as humans and animals. Of course evolution has designed our bodies to accomplish these tasks in an incredibly efficient way. Architects and Engineers are on a continuing quest to make building systems as efficient as possible, lowering their impact on the environment.
- As an introduction to Green Architecture, I’ve chosen to show this striking house. It is located down under, in Australia. It was constructed in 1975. That’s kind of before green architecture, eco-friendly design, and the like were even in the popular mainstream the way they are today. I think that by studying this one house, you can learn much of what you need to know about the process of green architecture. After you’ve mastered this building, It’ll then just be a matter of applying principles learned to other situations.Magney House by Architect Glenn MurcuttBingie Point, NSW, Australia – on the southeast coast on the Tasman Sea, between Sydney to the north and Melbourne to the South.This is a vacation home. It is isolated. It functions mostly off the grid meaning it does not hook up to infrastructure the way most of the buildings we use around here do.
- Hot and arid in the summer Cool in the winter Temp rarely falls below freezing.Off the ocean – prevailing winds from the north. Views to the north Builing Runs east-west Living areas to the north, south side has service spaces. – circulation corridor down the middle.Water reuse – reuse for drinking and heating system. Drains down central trough into downspout on either side of house into an underground cistern.Energy ConservationLouvers block sun light in summer from north.Orientation takes into account prevailing winds.Overhang blocks high summer sun, lets in low winter sun
- Passive Solar – block walls and massive concrete floor slabs absorb heat during the day, release the heat at night.Curved shape of roof on the north side allows the prevailing winds to enter the upper (clerestory windows) and rise up and over the floor area and drop down toward the rear of the house.Efficiency and flexibilityInterior rooms are easily reconfigured with the open verandah.Materials and ResourcesMurcutt takes into account the primary and secondary energy required to build his structures. (sometime referred to as embodied energy). While wood at first may seem like a low impact resource, Murcutt considers the secondary energy to transport and process the wood. On the other hand, aluminum and metals may have a high primary energy cost, but their transportation, installation and longevity outstrip those of wood, so that on balance, at least in the Australian economy and geography, metal has a lower overall impact on the environment.I really love this piece of architecture because if fuses green design concepts with a beautiful architectural form which perfectly integrates with the function of the house.
- Now we’re going to jump forward about 35 years to the present. I’m going to show you a couple of examples of green roofs. In the Magney house, the roof took on a dual function. It protected the occupants from the weather and collected rain water. In green design, roofs are now sometimes designed as a replacement of the ground that was there before the building was put in place.This is the ACROS Fukuoka building in Fukuoka City, Japan. It was designed by Architect Emilio Ambasz. It houses offices, retail space, a 2,000 seat theatre and a museum
- This is the Musée du quaiBranly (Quai Branly Museum ) designed by the architect Jean Nouvell of France. Here they have taken the concept of a green roof and turned it vertically so that it is a kind of green or garden wall. These hanging garden walls were designed by a French botanist named Patrick Blanc who works at the French National Centre for Scientific Research. He studies plants of southeast Asia and was inspired by cliff and grotto walls which support the growth of mosses. Mr. Blanc has installed this system on a number of buildings in Europe over the last several years.
- Green RoofsHigh insulation value for the roof, makes building more energy efficientReflects lightAbsorbs lightRetains water during a storm, reduces rate of water runoff – which reduces load on city’s infrastructure.Requires increased structural capacity – which increases the cost of the building.Different thicknesses of planting systems.Sedum is a typical low maintenance plant amongst others.The green roof can also be programmed as a roof garden for users of the building or others to use as a park space increasing the quality of life in the city.
- This building may be the mother of all green buildings in the US at the moment. It is a living laboratory of green architecture. Both research and practice rolled into one. It is just a simple office building, yet is a unique and special structure. It’s not going to win any architectural design awards for it’s aesthetics, but it has subtle, hidden beauty. This building could help to lead the way to the future of how we are to construct buildings in the United States, and perhaps the world. This is called a ‘NET ZERO BUILDING’. That means that over the course of a typical year, it will have a net energy use of zero. For every unit of energy it draws from the electrical grid at some point, it will return that unit of energy back into the grid at another point in time over the year, for example when the sun is overhead and it’s Photovoltaic cells are producing more energy than the building needs. This is when the electrical meter will literally spin backwards.This is the Research Support Facility of the National Renewable Energy Laboratory which is a division of the Department of Energy (DOE), which means that is was commissioned by the Federal Government. It is located outside of Denver CO.It Is a showcase for energy efficiency and renewable energy technologies222,000 ft2Cost - $64 Million. – twice the cost per s.f. for an avg. office bld’g. in the Denver Area.Opened in July of 2010Houses 750 Employees
- Wings are oriented East-WestRoofs are completely covered by Photovoltaic solar cells, with additional cells in the adjacent parking lot areas. These are solar energy collectors that convert photons from sunlight into direct current electricity. As a footnote, if one were to cover every square foot, walls and roof, of a mid rise building with solar cells, you’d provide approx. 35% of the total energy needs of that building.No fixed thermostat – will fluctuate between 68 and 80 degreesTrombe walls – hold heat or cold and release back to building slowly.Thermal mass in cellar fed by fans and transpired wall. (similar concept of ancient adobe architecture of the native Americans). The transpired walls consist of a double layer with an air gap in between. The sun heats up the outer layer of the transpired wall and fans draw that heated air down into the cellar catacombs of concrete blocks which absorb and store the heat. In early morning and later at night when the outside air is cool, the fans blow building air over the blocks to heat it for circulation into the building. Running the fans takes much less energy than running a heating system.The building has a constant process of monitoring and adjustment of systems as the building is used. The energy models can never be 100% predictive. The scientists and users will be constantly tweaking the systems until they are optimized.
- These are two views of the interior lobby areas. These show how natural light is utilized to reduce the amount of artificial lighting (and thus energy usage) required. The two story space on the right has several other features. The wood paneling used is actually reclaimed wood. It is from trees that were harvested from bark beetle infested trees. This pest has killed millions of acres of pine trees in the Rockies including CO. The reception desk top is made of sunflower seeds bonded together in environmentally friendly clear adhesive. Aggregate, which are the small pieces of stone and gravel in concrete, in foundation/concrete slabs comes from the demolition of Stapleton airport. The picture at the bottom left is a photograph of a typical office area. It shows the combination of natural and artificial light.Employees only have control of a 10 watt light over their desk, all other light is monitored and controlled by the building management system – using day lighting sensors to turn room lights on and off automatically depending upon what the sun and clouds are doing.Some windows will open and close automatically as per computer program that monitors temperature and humidity inside and outside.The photo on the right is from a computer modeling program used to calculate and project how light will bounce around the space. It’s the same programs that are used to generate computer graphics for Pixar and other animated films.
- How do I know if I have designed and constructed a green building? (ask for ideas from audience). To help a building owner answer that question, many non-profit organizations have developed design guidelines and corresponding rating systems to help measure the methods and levels of environmental savings that a design has. Architecture is a process of relationships. It is not so much about absolutes.So when we say we are making a building more energy efficient as part of green design, more energy efficient than what?Measuring the greenness of buildings is about establishing baselines. Establishing a general industry level and then saying, we’ll do X% better than that, then we’re green. This is usually based upon the current building energy code requirements, which themselves are updated to be more energy efficient every several years. So this is a game of relativity.This chart shows some of these green rating systems.How many of you have heard the term LEED? LEED stands for Leadership in Energy and Environmental Design. It is but one of many green building rating systems, but has become probably the most prevalent and most well known at the moment. I just wanted you to be aware that there are various rating systems each with unique attributes. The ISO 140001 system is a more facility based holistic type system used in Europe and much of the rest of the world.
- This is some detail on the LEED rating system. LEED updates it’s own system every several years. The current version is 3.0. Individuals can be accredited by LEED (or the USGBC which publishes the LEED system). I passed the exam, which is now administered by the Green Building Institute so I have my LEED AP credentials. If I were to take the exam today, I’d have to declare which flavor of LEED accreditation I wanted. There is no prerequisite for sitting for the LEED exam, in other words anyone can take it.
- I’m going to run you through the LEED checklist quickly. I don't expect you to memorize this. I just want you to get an idea and feel for the types of issues and the structure of the process. This is the LEED version 2.2., which was the version that was used to design building that I am working on currently which I’ll show in a minute. I have also indicated which credits depend upon the architect, the contractor or both. The checklist is broken up into six major categories which are highlighted in the gray bars. You earn points for each credit that you accomplish. The number of total credits tells you which level of LEED you are planning to achieve, certified, Silver, Gold, or Platinum. At the start of the project you make a commitment, kind of like a pledge, to get certain points. Then by the end of the project, you must submit documentation to the USGBC, who reviews this documentation and either accepts or denies your credits. After final approval by them, your building is officially LEED certified.At the start of a project, the entire design team holds a charette (which is a term for a kind of all-nighter that students would hold at the Ecole des Beaux Arts in Paris in the olden days). During that session, they brainstorm and try to figure out which credits would fit most easily into their particular project. Most categories have pre-requisites without which you cannot get any of the LEED certifications.Sustainable Sites deals with how the building sits in and relates to the environment, from encouraging public transportation to designing the outdoor lightning on the building and parking lot to be as low as practical so as to reduce light pollution.Water efficiency seeks to reduce the use of freshwater by utilizing low flow toilet fixtures and also recycling water within the building.
- Energy and Atmosphere deals with energy efficiency. Optimize energy performance is a sliding scale. The better you do compared to the minimum of the building code energy efficiency requirements, the more points you get. We are also installing solar thermal hot water heating, which is reflected in the On-site renewable energy. So the calculations prepared by the engineer indicate that on average 2.5 % of all of the energy needs of the building will be provided by this solar system.Innovation & Design Process allows the team to in essence create their own credits. For example on this project, the architect has designed a special electronic display which will show the status of the energy flow from the solar thermal hot water system. The purpose of this is as an educational aide, which was accepted by the USGBC as a valid credit. A project also gets a credit for having at least one LEEP AP professional involved.
- Materials and Resources deals with saving material and the corresponding energy needed to manufacture and transport those materials. For example, if you can show that at least 20% of all materials used in the building come from within a 500 mile radius of the project site, you’ll get 2 points.Indoor Environmental Quality deals with creating the healthiest environment within the building as possible. It addresses light, air, temperature, and viewing conditions within the designed spaces.The project that I am currently working on is the Lehman New Science Facility at Lehman College. It was designed by Perkins + Will architects. I am part of the owner’s team onsite working with the construction manager and contractors. This building is projected to be a LEED platinum building. There are not a great many university science and research buildings that have achieved the platinum status to date. Science buildings present greater hurdles to overcome in terms of air systems because they require so much more air than other types of building, which requires more heating and cooling and therefore more energy. So it was a great job of planning by the design team to figure out how to squeeze platinum out of this project. Now, if you’re a betting type, you might want to bet on this project, because the platinum is not guaranteed at this point. Some of the credits are part of the construction process, so there’s always the possibility that we’ll mess up on two of the credits, in which case we’ll drop down to gold at 51 points. Actually, in all public presentations, the college and CUNY always officially says that the building is going to be gold, to cover themselves, but I’m an optimist on this one. I think that we’ll be able to keep all of our points until the end.
- Here is a photos of the building under construction.
- This photo shows a bank of detention basins. Each tank is 20’ high and about 15’ in diameter. A series of pipes near their lower portions interconnects them. These have been incorporated into the project as part of the LEED credits that deal with stormwater quality and quantity. In a heavy rainstorm, these tanks will fill with the rainwater before it is dumped into the sewer system. This will buffer the sudden violent release water that would otherwise happen without the presence of these tanks. The tanks will fill successively. In addition, sand at the bottom of them will help to remove small particles from the storm water (called turbidity) reducing water pollution once this water finds it’s way out to the Hudson River and Lower New York Harbor.
- This shows ductwork protected by plastic wrap. This is part of the indoor air quality management credit. This ensures that once these duct sections are installed and connected together that when the building air system is turned on, it will not spit out dust and debris onto the occupants.
