The LEED process is a tool to look at sustainable design. 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. Certified Gold Platinum
A prerequisite must be achieved in order for a building to be certified, regardless if it is seeking a certified, silver, gold or platinum level. Achieving any individual credit is optional – points are awarded for achieving credits. The greater the number of points, the higher the level of certification is awarded.
Sustainable Sites Prerequisite:Erosion & Sediment Control Cr. 1:Site Selection Cr. 4:Alternative Transportation Cr. 5:Reduce Site Disturbance Cr. 6Stormwater management Cr. 7:Reduce Heat Island Effect Cr. 8:Light Pollution Reduction
Prerequisite 1: Erosion & Sedimentation Control Prepare an E&S Plan Install silt fences around perimeter of property Protect storm sewers from sediment Protect topsoil by stockpiling for later use Plant grass to prevent wind erosion of soil
SS Credit 4.2: Bike Storage Bicycle storage, showers & change facilities for 5% of building occupants
SS Credit 4.4: Parking Size parking to meet zoning requirements and provide preferred parking for car pools Consumes less fuel Fewer vehicles on roads Fewer vehicle exhaust emissions 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
Water Efficiency Cr. 1Water 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!
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!
Energy and Atmosphere Prereq. 1Building System Commissioning Prereq. 2 Minimum Energy Performance Prereq. 3 CFC Reduction Cr. 1Optimize Energy Performance Cr. 3Best Practice Commissioning
Prerequisite 1: Building System Commissioning Commissioning is a process that ensures all of a buildings fundamental systems and elements operate as they were designed to do. Saves energy and money Verifies that spaces receive adequate ventilation Confirms that controls operate as expected
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 CFCs are a chemical that damages the ozone layer By using equipment that is CFC-free, we help protect ourselves against harmful UV rays What can you do to protect the ozone layer?
Credit 1.1: Optimize Energy Performance WMES is 46.9% more cost efficient with regard to energy consumption than a typical building. Thats a lot of energy being saved! Enough to W light bulbs … … 24 hours a day for 365 days a year Thats a lot of money being saved! About $70,000 per year Or close to $200 per student What do you do to save energy?
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 tonnes of this was diverted from landfills Thats a diversion rate of 78.5% How much of your household waste is diverted from the landfill? Thats the weight of 5 adult elephants
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. 1Minimum Indoor Air Quality Performance Prereq. 2Tobacco Smoke Control Cr. 3Indoor Air Quality Management Plan During Construction Cr. 4Low-Emitting Materials Cr. 8.2Views 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 VOCs – thats Volatile Organic Compounds VOCs evaporate at room temperature, and our bodies (and noses) are very sensitive to them VOCs arent good for us … so products containing as few as possible were used … … 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 workers 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. 1.1Scent-smart policy Cr. 1.2Exemplary performance for using Regional Materials Cr. 1.3Exemplary performance for Water Use Reduction Cr. 1.4Green Education & Demonstration Program Cr. 2LEED Accredited Professional
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:
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.
