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
