Heat recovery ventilators now required in all new Vancouver homes

With the City of Vancouver’s Green Homes Program, new homes are required to be better insulated with less air leakage than ever before. This means lower heating costs. Unfortunately, it can also lead to stuffy, stale indoor air.

 

To prevent this, the City is now also requiring a heat recovery ventilator (HRV) to be installed in every new home.

 

An HRV delivers fresh outdoor air into a home’s ventilation system while also exhausting stale outdoor air. But, unlike with other ventilation systems, operating an HRV results in very little energy loss. This is because an HRV will transfer the heat from the outgoing stale air into the incoming fresh air. It does so by passing the air through a countercurrent heat exchanger, where the air flowing in each direction is passed through an array of narrow passages. As the outgoing indoor air flows through the narrow passages, its heat is transferred into the incoming outdoor air. Up to 90% of the heat can be saved.

 

 

In short, an HRV is an energy efficient way to keep your home’s air fresh.

 

All BC homeowners who have not already received a LiveSmart BC grant can receive a $800 grant when they install an HRV in an existing home.

ecoENERGY program closed early to new participants

Last summer, the federal government announced the ecoENERGY program would be renewed until March 31st, 2012. But they also announced that it would be available to only 250,000 homeowners. On January 28th, it was announced that 250,000 homeowners had registered to begin the program. If you have not already registered for the program, you are not eligible to receive grants.

If you have already registered for the program, you have until March 31st to complete your pre-retrofit evaluation and your renovations. Then you have until June 30th to complete your post-retrofit evaluation. The grants available can be seen at http://oee.nrcan.gc.ca/residential/personal/retrofit/4171.

The LiveSmart BC program is still available until March 31st, 2013 (or until funding is depleted). See our grants & rebates page for details.
