Living Building Challenge

We're building one of the greenest homes on earth.

“The Confluence” — a living building in southern Alberta

SAIT’s Green Building Technologies (GBT), Woodpecker European Timber Framing and an Alberta family have partnered to construct a one-of-a-kind home in the foothills of southern Alberta — one that produces more energy than it uses, captures water on site and creates a positive impact on its people and environment.

Together, they hope “The Confluence” will achieve the highest possible certification through the Living Building Challenge, the world’s most rigorous green building rating program and sustainable design framework. They're aiming for the home to be the fifth in the world — and the first of its kind — to do it.

Explore the home

Explore the 2,238 square-foot, three-level home nestled in the foothills of Alberta, Canada, just west of the town of Cochrane.

Living building challenge kitchen
The colours, textures and patterns of interior wood, stone and glass blend to create a modern yet homey feel throughout the kitchen and living room.
Living building challenge bathroom
The upstairs washroom, designed around a salvaged vanity, combines soft colours and textures which juxtapose nicely against the black window frame and picture-perfect view.
Living building challenge bathtub
A quiet and calming retreat. The sand tiling commands a comforting, peaceful presence similar to ocean waves on a beach or the nearby riverside.
Living building challenge bedroom
Two massive windows, with views over the forest canopy to the distant Rocky Mountains, flood the master bedroom with daylight.
Featuring a custom, oversized fir front door, the tile and wood foyer provides a warm welcome to family and friends.

Confluence (kän-ˌflü-ən(t)s):

a coming or flowing together, meeting, or gathering at one point.

"The Confluence" represents a confluence of natural and built environments, the Rocky Mountains and the prairies, new and salvaged materials, and human and environmental health — to name a few.


Living building challenge house

The house that green tech built

To achieve the gold standard in sustainability goes beyond installing solar panels and low-flush toilets. GBT and the Centre for Innovative Information Technology Solutions — both divisions of SAIT’s Applied Research and Innovation Services (ARIS) department — are applying emerging green technologies that could change the way we build homes.

What is the Living Building Challenge?

The Living Building Challenge (LBC) is the world’s highest standard for building green, administered by the International Living Future Institute headquartered in Seattle, Washington. To achieve full certification, projects must adhere to seven areas of sustainability. After construction, projects must be monitored for 12 months to prove sustainable performance — a requirement setting it apart from other green rating systems.

Homeowners

Gerton and Joleen Molenaar wanted to build a home that not only sheltered their family but helped inspire a greener world. They learned about the Living Building Challenge and approached SAIT and Woodpecker European Timber Framing to enlist the expertise needed to execute the complex challenge.
