(not required for laneway homes)

  1. Furnace/ Boiler: 92% efficient AFUE, no side venting
  2. Hot Water Tank or on demand: domestic hot water heater must be 78% or greater efficiency or at indirect source. Electric tank to be wrapped RSI 1.75 (R10)
  3. Hot Water Pipe: the first 3M from and the last 1M to all hot water shall have pipe insulation with an RSI of 0.35 (R2)
  4. Recirculating System: the entire pipe system must be wrapped with pipe insulation with RSI 0.35 (R 2.84)
  5. Gas-fired fireplaces in conditioned spaces: shall use a) intermittent pilot ignition (IPI) systems, or b) on-demand ignition systems that automatically shut off within 7 days of appliance non-use
  6. Wood Burning Heating Appliances: produce not more than 2.5 grams per hour of particulate air contaminant emissions for catalytic appliances, or produce not more than 4.5 grams per hour of particulate air contaminant emissions for non-catalytic appliances

Electric Vehicle Charging: (Info on plans)

Solar Ready Pipe Run: (info on plans)

  1. Two 50 mm diameter pipe chase for connection

EnerGuide Requirements: (info on plans)

  1. Pre-Permit checklist and P file submission (Plans evaluation energy model)
  2. Pre-drywall checklist and air leakage testing(Prior to City insulation inspection)
  3. energy rating stickers must be left on windows at time of pre-drywall verification by CEA
  4. Final Blower door test and EnerGuide Report (prior to final occupancy)
