Specifications & Resources

  1. AQ 1.1 applies where Transportation Impact Study (TIS) is required as part of a development application as outlined in the City of Toronto Guidelines for the Preparation of Transportation impact Studies (2013). Prior to undertaking a formal TIS, it is recommended that City staff be consulted to confirm whether a TIS is required and determine the scope of analysis required. Travel Demand Measures may include but are not limited to improvements to pedestrian connections, bicycle parking/bike stations, and dedicated parking for car-sharing vehicles.
  2. AQ1.2 only applies where there is a minimum Zoning Bylaw car parking requirement. The effective Zoning Bylaw is the applicable bylaw in effect for the subject property on the date of the application.
  3. Low-emitting vehicles (LEV) are defined as vehicles having a Combined Fuel Consumption Rating (CFCR) of 6.5L/100km or less, as defined by Natural Resources Canada’s Office of Energy Efficiency. Car pooling is when 2 or more workers share a car ride to work locations. Car-sharing refers to fee-based, shared automobile use that is intended to substitute for private vehicle ownership. It makes occasional use of a vehicle affordable, while providing an incentive to minimize driving and rely on alternative travel options as much as possible.
  4. For institutional, commercial and retail developments, the number of dedicated priority parking spaces (LEV, car-pool or car share) should be no less than 1 dedicated space for every 10 parking spaces provided above the minimum Zoning Bylaw requirement.
  5. Electrical Vehicle provision means Level 2 Electric Vehicle Supply Equipment (208/240 VAC) installed in compliance with Section 86 of the Ontario Electrical Safety Code. Provide to each designated parking space. The physical provision to permit future EVSE installation consists of empty raceways or conduits starting in a junction box in the electrical room and terminating in a junction box central to each parking garage floor. This conduit will be empty to accommodate future wiring.
  6. The Ontario Building Code includes requirements for electric vehicle charging systems.

Tier 2

AQ 4.3 UHI Non-roof Hardcape (Core)

Use any combination of the strategies in AQ 4.1 to treat at least 75 per cent of the site’s non-roof hardscape (including driveways, walkways, courtyards, parking areas, artificial turf and other on-site hard surfaces).9

Specifications & Resources

  1. Solar Reflectance Index (SRI) is a measure of a surface’s ability to reflect solar heat. The SRI for a given material is calculated using both the reflectance value and emittance value of the material. Black asphalt has an SRI of 0 and a standard white surface is 100. Pavement types range between these values with a SRI of 35 for gray concrete.
  2. Open grid pavement consists of concrete or hard plastic grid systems with large pore spaces filled with a planted growing medium or light coloured aggregate.
  3. Shade of 10-year canopy width is measured at solar noon at the summer solstice (approximately June 21). Refer to EC2.1 – 2.5 for the applicable tree planting standards. Shade cast by buildings is not an eligible strategy.
  4. Energy generation systems consist of solar photovoltaics (PV), solar thermal collectors and wind turbines.
  5. Refer to LEED V4 BD+C SS Credit: Heat Island Reduction Option 2. Parking spaces do not include drop off and loading areas. Acceptable cover includes: underground, under deck, under roof, under building. Uncovered parking at the top level of a multilevel parking structure is not required to meet the prescribed roof criteria because it is considered non-roof surface.
  6. Refer to the Green Roof Bylaw for definitions of Green Roof and Available Roof Space, details on calculating the green roof area required and the Toronto Green Roof Construction Standard.
  7. A Cool roofing materials must have a minimum initial reflectance of 0.65 and minimum emittance of 0.90 or a 3-year aged SRI value of 64 for a low-sloped roof and a 3-year aged SRI of 15 for a steep-sloped roof. Low sloped roofs have a surface slope of less than 1:6 (9.5 degrees) and steep sloped roofs have a surface slope greater than 1:6 (9.5 degrees).
  8. Consider designing green roofs to promote biodiversity. Refer to the City of Toronto Guidelines for Designing for Biodiversity on Green Roofs.
  9. For Tier 2 applications only, a weighted average may be used to calculate non-roof hardscape treated areas using the weighted average calculation.
