The Good News!
Since 2007
14% increase in Floor Space
11% increase in population
50% drop in price of natural
gas
No increase in GHG’s!

How do we get there? (with Infrastructure
Downtown
Cambie Corridor
Central Broadway
Cambie Corridor - Context
Existing Systems:
• Children and Women’s Hospital steam
system (conversion opportunity to reduce
CO2 emissions by 10,000 tonnes/year)
Demand Context:
• Large development sites such as Oakridge,
Pearson Hospital, Little Mountain not
currently served by Neighbourhood Energy
• Corridor-wide redevelopment underway
• Connection policy in place
Cambie Corridor - Strategy
• Convert C&W steam heat system:
– Require as condition of Children and
Women’s hospital rezoning
– Create supportive policy for low-carbon
conversion
• Evaluate business case of establishing NE
systems at large development sites and
explore competitive process to establish
service area contracts
• Clarify connection policy
Downtown - Context
Existing Systems:
• Central Heat (largest CO2
reduction opportunity in City
>70,000 tonnes/year)
New Systems:
• NEFC, SEFC
Demand Context:
• Significant development activity
including False Creek Flats, West
End, Granville Loops, CBD
• Existing gas heated buildings
convertible to NE
Downtown - Strategy
• Enable the Conversion of Central Heat:
– Require any expansion to be low carbon
via utility contracts (e.g. NEFC)
– Create supportive policy for low carbon
conversion
– Utilize rezoning conditions to require low
carbon heat for new buildings
– Investigate complimentary low carbon
options through a competitive process
• Implement connection policy for new service
areas
