Specifications and Resources

  1. AQ 1.1 applies where Transportation Impact Study (TIS) is required as part of a development application as outlined in the Development Guide Terms of Reference for the Preparation of Transportation impact Studies. 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 carsharing vehicles.
  2. AQ1.2 only applies where there is a minimum Zoning By-law car parking requirement. The effective Zoning By-law 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. Electric vehicles are considered LEV. Carpooling is when two or more workers share a car ride to work locations. Carsharing 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, carpool or carshare) should be no less than one dedicated space for every 10 parking spaces provided above the minimum Zoning By-law requirement.
  5. EVSE, or energized outlets or receptacles, are acceptable to meet the requirement. All electrical circuits shall be 208-240 VAC single phase with a minimum circuit rating of 32Amps (40 Amp branch breaker). Electric vehicle supply equipment (EVSE) is defined by the Ontario Electrical Safety Code as: the complete assembly consisting of cables, connectors, devices, apparatus, and fittings, installed for the purpose of power transfer and information exchange between the branch circuit and the electric vehicle.
  6. Parking spaces are defined as inside the building, excluding outdoor parking lots. Provide Level 2 charging capability to the required % of enclosed dedicated parking spaces or by using an electric vehicle energy management system (EV EMS).
  7. Rough-in provisions include empty raceways starting in a junction box in the electrical room and terminating in a junction box central to each parking floor. Raceways will be empty to accommodate future wiring.
  8. Section 86 of the Ontario Electrical Safety Code includes provisions for and permits the use of electric vehicle energy management systems (EV EMS) to monitor electrical loads and to control electric vehicle supply equipment loads.
  9. EV EMS refers to a variety of technologies used to monitor and control electrical loads associated with charging EVs, also referred to as load sharing, load management, panel or circuit sharing or smart charging. EV EMS prevents circuit loads from exceeding the ampere rating of the circuit. Rough-in the remaining parking spaces for future EVSE.
    The system must be capable of supplying a minimum performance level of 16 kWh average per EVSE, over an 8-hour period, assuming that all parking spaces are in use by a charging EV:
    16kwh/8hrs translates to a 2000W circuit per parking space minimum. For example: 2000W/208V @ 9.6A per outlet or 2000W/240V@ 8.33A per outlet.
  10. Energized outlets or EVSE parking spaces shall be labelled for the intended use for electric vehicle charging.

AQ 4.2 Green and Cool Roofs

For new buildings or building additions with a GFA greater than 100m² provide the following:

  • Green roof equal to the greater than 50 per cent of the Available Roof Space or the coverage requirement of the Green Roof By-law
  • Cool roof on areas of Available Roof Space not covered by green roof area.5,6,7

Specifications and 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 the Green Roof By-law for definitions of Green Roof and Available Roof Space, details on calculating the green roof area required and the Toronto Green Roof Construction Standard. Definition of Available Roof Space includes exclusions for areas dedicated to renewable energy generation.
  6. Cool roofing materials must have a minimum initial reflectance of 0.65 and minimum emittance of 0.90 or a three-year aged SRI value of 64 for a low-sloped roof and a three-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).
  7. Consider designing green roofs to promote biodiversity. Refer to the City of Toronto Guidelines for Designing for Biodiversity on Green Roofs.
