Blossom Park Passive House Supportive Housing Redevelopment

Project Description

This project includes the redevelopment of a group home run by Indwell into 34 supportive apartments and a community hub that will be shared with other nearby tenants. The average unit size is 34m2 and includes a washroom, kitchenette, bedroom, and living space. Common spaces include a large community kitchen, laundry room, lounge, dining area, storage space, and offices for Indwell staff. The project was tendered at a construction cost competitive with other non-PH projects at $195/ft2.

The development is currently under construction with Trigon Construction Management. The main construction of the exterior walls, windows, and airtightness layer is being built off-site in Kansas as a prefab BuildSMART system.

The walls are designed to be an impressive R55 effective. Triple-glazed PH-certified indows included with the BuildSMART system are by Klearwall. The remainder of the structure is wood studs, TJIs, and trusses.

A unique catwalk in the unconditioned attic provides access to the four Swegon Gold ERV units manufactured in Mississauga. Heating & Cooling is provided by Mitsubishi VRF units in each apartment along with solar and latent gains.

Passive House Consulting was provided by Zon Engineering, Mechanical & Electrical design by CK Engineering, and Structural by Kalos Engineering. This is the third multi-unit residential building designed by Invizij Architects for Indwell, a Hamilton non-profit who have committed to the PH standard.

Oxford County has been a key partner in this project, as Blossom Park is helping direct future development for the County which aims to be net zero by 2050.
