STRATEGY PURPOSE

slide-15
SLIDE 15

Greenest City Action Plan The City is aiming to reduce city-wide GHG emissions by 33% and reduce GHG emissions in existing buildings by 20% by 2020.

STRATEGY PURPOSE

15

slide-16
SLIDE 16

16

55% of total GHG emissions are from buildings:

Nearly a quarter of planned GHG reductions* from building retrofits.

16

STRATEGY PURPOSE

* Excluding targeted reductions from Provincial legislation on vehicle fuel standards, vehicle efficiency and clean power.

Building Retrofits, 23% Waste, 7% Electric Vehicles, 5% Increased Walking, Bike & Transit, 32%

Neighbourhood Energy17%

New Building Energy Efficiency, 16%

The Greenest City Action Plan targets 160,000t of GHG reductions from existing building retrofits

slide-17
SLIDE 17

BACKGROUND ON RETROFITS

Barriers to Retrofitting Our Buildings:

  • Hard to access and compare energy use data
  • Low owner awareness of cost saving opportunities
  • Competing demands and lack of owner expertise
  • Low natural gas prices

Opportunities:

17

BACKGROUND ON RETROFITS

  • Improve housing affordability by reducing energy costs
  • Support green jobs
  • Pilot new approaches
  • Leverage and enhance existing incentives through

partnerships with BC Hydro, Fortis BC, and strong industry associations
