This demonstration module is the outcome of modeling and engineering high performance prefabricated panels capable of meeting Passive House insulation and airtightness specifications as well as meeting the BC Energy Step Code net zero energy ready (Step 5) performance targets for buildings constructed in the Northern BC Climate Zone.
By understanding how to meet the highest levels of energy performance, Winton is now able to assist commercial and residential customers in constructing assemblies to help their project meet the intermediate steps of the BC Energy Step Code.
As a regional forest products supplier, Sinclar Group Forest Products and Winton Homes believe that the lower embodied carbon and ecological footprint of wood-based construction components can help the Province of B.C. meet its overall Greenhouse Gas reduction targets. Increasing demand for innovative solutions manufactured in the North, also strengthens regional economies and communities involved in the forestry sector.
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:
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.
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.
