Leadership in Energy & Environmental Design (LEED) Intended to transform the market Promote integrated design Recognize environmental leadership Raise awareness Prevent false claims – “Greenwashing” USGBC established in 1993, CaGBC in 2003 LEED is not a perfect system – but it has successfully met it’s goals History In response to environmental concerns, the USGBC was established in 1993, with the intention of accelerating the adoption of green building practices, technologies, policies and standards. In order to stay competitive, the building industry needed to address the economic and environmental consequences of its building practices. To do this, the USGBC developed the LEED rating system to promote market transformation. LEED is a certifying system designed for rating new and existing commercial, industrial and high-rise residential buildings. Different levels of green building certification are awarded based on credits earned in several categories including site, energy, water, material resources, and indoor environmental quality.   In Canada, several green building programs were initiated throughout the 1990’s including the C2000 program, BEPAC green building rating system, GreenGlobes, the International Green Building Challenge, and BREEAM Canada. The CaGBC was established in 2003 to further encourage the adoption of green building practices across Canada. 7 7 7

SS Credit 4.4: Parking Consumes less fuel Size parking to meet zoning requirements and provide preferred parking for car pools  Consumes less fuel Fewer vehicle exhaust emissions Fewer vehicles on roads Less area required for parking = more green space

SS Credit 5.2: Development Footprint Designate a green space equal in area to the building footprint that will be preserved for the life of the building.  For schools, the sports field works very well as the designated green space.

SS Credit 7.2: Heat Island Effect - Roof Reduce the heat island effect by using reflective roofing materials  Want to learn more about the heat island effect? Check out this Health Canada publication: The Urban Heat Island Effect: Causes, Health Impacts and Mitigation Strategies

SS Credit 8: Light Pollution Reduction Prevent any light ‘spill-off’ from the property to both adjacent properties and upward into the night sky. Image from http://imageshack.us/photo/my-images/213/nightskiesstellarium.jpg/

Water Efficiency Cr. 1 Water Efficient Landscaping Cr. 2: Innovative Wastewater Technologies Cr. 3: Water Use Reduction

Credit 1: Water Efficient Landscaping The landscaping does not require potable water to be maintained. The native and adapted species can survive using only rainwater. Red Maple Sugar Maple Pin Oak

Credit 2: Innovative Wastewater Technologies A cistern stores rainwater collected from the roof, which is then used to flush toilets and urinals. This saves more than 650,000 litres of fresh water per year! http://www.epa.gov/oust/graphics/clipart.htm

Credit 3: Water Use Reduction Low flow fixtures reduce water by more than 64% of a typical school. This school used one millions fewer litres of fresh water than a typical school! http://www.epa.gov/oust/graphics/clipart.htm

Energy and Atmosphere Prereq. 1 Building System Commissioning Prereq. 2 Minimum Energy Performance Prereq. 3 CFC Reduction Cr. 1 Optimize Energy Performance Cr. 3 Best Practice Commissioning

Prerequisite 1: Building System Commissioning Commissioning is a process that ensures all of a building’s fundamental systems and elements operate as they were designed to do. Confirms that controls operate as expected Verifies that spaces receive adequate ventilation Saves energy and money

Prerequisite 2: Minimum Energy Performance A LEED certified building must be at least 25% more energy cost efficient than the Model National Energy Code for Buildings (MNECB) Waverley Memorial Elementary School is 46.9% more energy cost-efficient than the MNECB – this will earn 5 additional points under the “Optimize Energy Performance” credit.

Prerequisite 3: CFC Reduction CFC stands for Chlorofluorocarbon What can you do to protect the ozone layer? CFCs are a chemical that damages the ozone layer By using equipment that is CFC-free, we help protect ourselves against harmful UV rays

Credit 1.1: Optimize Energy Performance WMES is 46.9% more cost efficient with regard to energy consumption than a typical building. That’s a lot of money being saved! That’s a lot of energy being saved! Enough to 850 100W light bulbs … About $70,000 per year … 24 hours a day for 365 days a year Or close to $200 per student What do you do to save energy?

Materials & Resources Prereq. 1 Collection & Storage of recyclables Cr. 2 Construction Waste Diversion Cr. 4 Recycled Content Cr. 5 Regional Materials

Prerequisite 1: Collection & Storage of Recyclables Every LEED Certified building requires a room or area dedicated to collecting and storing recyclables In addition, an area outdoors is also dedicated for storing recyclables and compost Cardboard Glass Metal Plastic Organics

Credit 2: Divert Construction Waste from Landfill 39.6 tonnes of waste were removed from the site during construction. 31.1 tonnes of this was diverted from landfills That’s a diversion rate of 78.5% That’s the weight of 5 adult elephants How much of your household waste is diverted from the landfill?

Credit 4: Recycled Content Some of the materials used to construct this school contain recycled material Concrete blocks Steel beams Whiteboards Insulation About 23.5% of all the materials used to construct this school contain recycled content.

Credit 5: Regional Materials Regional materials are those that are extracted and manufactured within a certain distance from the school Within 800km when transported by truck Within 2400km when transported by ship or rail

Indoor Environmental Quality Prereq. 1 Minimum Indoor Air Quality Performance Prereq. 2 Tobacco Smoke Control Cr. 3 Indoor Air Quality Management Plan During Construction Cr. 4 Low-Emitting Materials Cr. 8.2 Views for 90% of Spaces

Prerequisite 1: Minimum IAQ Performance This prerequisite ensures adequate fresh air is being supplied to people in the building IAQ stands for Indoor Air Quality What sorts of things might affect the air quality in a school? Why is having fresh air in a building important?

Prerequisite 2: Tobacco Smoke Control This prerequisite ensures smoking does not occur near any building openings, such as vents, doors and windows This is easy to achieve … … because smoking is not permitted on school property

Credit 3: IAQ Management Plan During Construction It is important to ensure everyone in the building has clean air to breathe. This includes the workers constructing the school Here are photos of some of the measures used to protect workers Gravel to keep workers from tracking dirt inside … ductwork is sealed to prevent dust from entering … low-emitting materials were used … fans were used to move fresh air throughout the building … porous materials were kept sealed until they were ready to be installed.

Credit 4: Low Emitting Materials Ever notice that after a room is painted, it smells bad? This is caused by VOC’s – that’s Volatile Organic Compounds VOC’s aren’t good for us … so products containing as few as possible were used … VOC’s evaporate at room temperature, and our bodies (and noses) are very sensitive to them … Products such as paints, adhesives, sealants, glues and carpet.

Credit 8.2: Views for 90% of Spaces Views to the outdoors are important for people in buildings … would you want to spend all day in a room with no windows? Windows allow people in buildings to connect with the outdoors, while still being productive In fact, studies have shown that having a view to the outdoors actually increases a worker’s concentration.

Innovation in Design Points can be earned for innovative designs and measures beyond the scope of the LEED rating system – here is what WMES has accomplished: Cr. 1.1 Scent-smart policy Cr. 1.2 Exemplary performance for using Regional Materials Cr. 1.3 Exemplary performance for Water Use Reduction Cr. 1.4 Green Education & Demonstration Program Cr. 2 LEED Accredited Professional

For a list of locally available scent-free products, visit: Scent Smart Policy No scents is good sense. Scented products, such as perfumes and colognes, can trigger asthmatic reactions for people sensitive to odours Keep your school as a safe environment for everyone and avoid using scented products For a list of locally available scent-free products, visit: http://lesstoxicguide.ca/

Exemplary Performance Exemplary performance credits are awards when the design team has gone above and beyond the LEED standards. Regional Materials: 39.1% of the materials used in construction are of a regional content. Water Use Reduction: WMES uses 64.1% less water than a conventional building

Green Education & Demonstration Having seen this presentation, do you have a better understanding of what features make your school a LEED certified building? What is LEED? Name some of the “green” features in your school What can you do to keep your school “green”?

LEED Accredited Profession (AP) A LEED AP helps guide the project from design through construction to ensure that LEED standards are met. A LEED AP may be an architect, engineer, designer, technician, or one of many skilled trades in the construction industry.
