Vancouver: city of green aspirations

green initiatives

"The False Creek Energy Center, for instance, has pumps that capture heat from untreated sewage, transfer the warmth to hot water, and then pipe it throughout a downtown neighborhood, providing "heat and hot water to 1.8 million square feet of homes and businesses" That is amazing! I do wonder though how they got around the building code. Plumbing codes must be different in Canada. I can't see this working in most of the US. Xtreme Green Homes is looking for more ways to reduce energy consumption for residential construction, perhaps this may provide some clues.

green initiatives - Neighbourhood Energy Utility

Plumbing code wasn't an issue - The Neighbourhood Energy Utility ("NEU" http://vancouver.ca/neu) is a district heating system, where thermal energy is produced centrally, distributed by insulated pipes buried in streets, then transferred to numerous customer buildings using heat exchangers.  While the energy source (sewage heat recovery) is different, the heat distribution technology is not uncommon and based on international best practice standards.  No sewage is piped through the buildings that are heated, and for domestic hot water the NEU uses a double-walled heat exchanger to protect domestic water potability.  Hope this helps.
