  • Saskatchewan's first Net Zero multi-unit residential building
  • 1 of 7 projects nationally
  • Results will provide direction to the National Building Code of Canada
Willowview Heights in the Willowgrove neighbourhood of Saskatoon features the province’s first Net Zero multi-unit residential building.

One of only seven such projects nationally, the building will be studied to provide direction to the National Building Code of Canada. The Net Zero units at Willowview Heights will be highly energy-efficient and it's designed so that any energy consumed can be offset by renewable solar energy generation in the future. 

Net Zero Ready features include:

  • R80 attic insulation
  • R36 insulation in the walls
  • Insulated concrete forms
  • Low-E, argon triple pane windows
  • Air source heat pump domestic hot water heaters
  • Hot water heat recovery drain coils
  • Right-sized, energy-efficient modulating furnaces with air source heat pump
  • Interactive energy monitoring system
  • Highly efficient LED lighting
  • Solar panel array
  • Passive solar design elements
  • Engineered modular construction method

Through its various housing partnerships, the NAHC is dedicating a percentage of the units as affordable units.

When this property was rezoned for residential development in 2018, Big Block applied architectural controls to the project so that the exterior features, materials and colours will complement neighbouring houses. Throughout the construction process, we will have regular communication with residents and will be making every effort to minimize disruptions. As a modular-built project, construction materials and supplies deliveries were reduced by up to 70% and overall build time was reduced by up to 50%.

Another environmentally-friendly benefit of modular builds is the reduced waste generated by its construction. The modules are built in a factory environment; with less material in transit and transition like on a building site, there is less likelihood of accidents, spills, and environmental damage to the material. The factory setting also makes it easier to reuse and recycle waste materials. Overall, it is estimated that waste is reduced from 10% to 15% in a conventional project to 5% with a modular-built project.

Additionally, consolidating work at a factory, in combination with the more efficient construction operations, results in modular-built projects producing up to 50% less CO2 emissions than conventional projects.

Construction on this project started in May 2020, and the project was completed and ready for move-in by October 2020.
