Affordable, accessible, and energy-efficient homes are no longer optional; they are often a requirement for CMHC funding. Meeting these three goals simultaneously can feel challenging, but building science provides the guidance to make it achievable.

‍

At BKC, we help builders and developers navigate this landscape. On the energy side, we identify design and material strategies that improve efficiency without inflating costs. On the construction side, we show how to build affordably while maintaining quality, from selecting cost-effective materials to optimizing building methods and high performance insulation and air tightness details.

Operational costs are just as critical. Affordable housing isn’t truly affordable if tenants face high utility bills. Integrating building science early ensures homes are not only built well but also built to perform efficiently and optimally.

Connect with BKC to leverage building science principles, optimize materials, and reduce operational costs through thoughtful planning so you can deliver homes that truly meet the needs of tenants today and into the future.

Recent case studies from Building Knowledge Canada, delivered in partnership with Trim Tab, show how these principles translate into real-world impact. By applying building science during unit turnovers in existing affordable housing, the project achieved meaningful energy and carbon reductions while improving tenant comfort—without the high costs typically associated with deep retrofits. This practical, scalable approach demonstrates how affordable housing providers can meet funding requirements, lower operational costs, and improve the quality of life for tenants, all at the same time.
