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.

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.)

In March 2020 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.
