Winton Homes, in partnership with Design Smart Construction, received funding from the CleanBC Building Innovation Fund. This funding, established by the Province of B.C. provides funding for projects that accelerate the availability and affordability of low-carbon building solutions including advanced building components, designs and new construction methods.


We gratefully acknowledge the financial support of the Province of British Columbia through the Ministry of Energy, Mines and Low Carbon Innovation.

While many municipalities are at different stages of implementing the BC Energy Step Code, it's inevitable that this energy-efficiency performance standard will be adopted across the province. It's designed to help the province meet its goal that all new British Columbia buildings must be net-zero energy ready by 2032.

A net-zero energy ready building is one that has been designed and built to a level of performance that it could, with the addition of solar panels or other renewable energy technologies, meet its energy needs entirely on-site. A building such as a passive house is one that has been designed and modelled to reduced energy demand enough to meet the rigorous certification of the International Passive House Standard. This type of building would easily reach the top step, Step 5, of the BC Energy Step Code.

Winton is working to provide affordable, low-carbon prefabricated homes that meet these new requirements.

Buildings constructed to meet higher performance standards require greater understanding of building science and attention to construction detailing. In order to achieve airtightness and reduce overall heating demand and energy use, buildings constructed to meet higher performance standards require:

  • increased insulation,
  • improved components such as windows, doors and HVAC,
  • greater attention to construction detailing,
  • greater understanding of building science.

Armed with in-depth knowledge from the CleanBC project and guidance from Design Smart Construction, Winton will be able to assist commercial and residential customers in constructing wall assemblies to meet each step of the BC Energy Step Code, and capable of reaching the Passive House standard.



This demonstration building looks small, but the partners involved are heavy weights!

The walls were prefabricated here at Winton, with the assistance of Design Smart Construction, where we sourced top quality materials and components from suppliers across BC and Canada.

For example the window and door package was supplied by Innotech based out of Langley BC, who offer a variety of high-quality products that achieve energy efficiency and performance standards. Sonoclimat wood fibre board was sourced from MSL in Quebec, and tapes and membranes from both 475 High Performance Building Supplies and Rothoblaas. A local crane operator helped erect the wall panels and local contractors finished the building exterior with Trex and Allura siding on this energy efficient, Step 5 demo module.

Winton extends a warm thank you to all the vendors, suppliers and partners that made this project possible.
