Multi-Family Residential


Multi-award winning Sustainable Townhomes

North Vancouver, BC

The Seven35 building on the North shores of Vancouver is a multi-award winning development and is the first installation of the PIRANHA wastewater heat recovery system.

In 2012, the 60 sustainable, two-story townhomes installed a PIRANHA T10 HC which uses wastewater to recover and save homeowners up to 75% in energy costs.

At the forefront of sustainable building, Seven35 has aggressively adopted several SHARC beta installations and became a key proving ground of SHARC & PIRANHA efficiency to the world (see EPRI Incubate Energy Challenge.)
