FUNDING ADVICE Consider the value of conducting a
building energy audit
Contact your utility providers to learn about incentives
Setup a Sustainability Reserve Fund CARIP / Carbon Tax
Return
Additional monies (in lieu of carbon offsets)
-
CHALLENGES Submitting funding applications to BC Hydro
Hired a contractor to complete application for 3 projects
Retrofits to an older building are not as efficient as similar
technology in new construction (e.g. Recreation Centre)
Monitoring energy savings can be a challenge
Political Will – what’s popular now? (e.g. solar hot water)
Expanding operations, energy use and costs
