Decarb Lunch Series: Does it cost more to build a high-performance home?

May 28, 2021 @ 7:00 pm to 8:00 pm

Free webinar hosted by ZEBx and HAVAN as part of ZEBx’s Decarb Lunch Series.


The Province’s CleanBC charts a course for net-zero energy-ready homes by 2032. That’s Step 5 of the BC Energy Step Code for Part 9 buildings. Between now and then, the CleanBC plan sets Step 3 as a minimum requirement by 2022 and Step 4 by 2027. If clients are concerned about future-proofing the value of their new home, they may ask about the difference in cost between a code-minimum home and one that meets the 2027 or 2032 requirements. How does a builder approximate this difference?

NRCan’s Cost Benefit Analysis Tool (CBAT) is a powerful and free Excel-based costing tool that can help the Part 9 building community approximate the cost of high-performance homes of the future. Join ZEBx and HAVAN on Friday, May 28 as they present the CBAT along with some real-world insight into how it’s been used.

What is the Cost Benefit Analysis Tool (CBAT)

CBAT (Cost Benefit Analysis Tool) is a costing tool aimed at part 9 new construction builds. CBAT combines energy modeling and costing in an easy to use tool that offers insights into the cost of energy efficiency. The tool is excel-based and allows builders and energy advisors (EAs) to identify cost-effective technologies and envelope packages that meet the goals of their project, and satisfy building codes and desired performance targets. CBAT includes a costing database that can be used for cost calculations as is, or customized to reflect local prices. Optimal solutions can include: lowest cost to build, lowest cost to operate, lowest total cost of ownership, lowest operational carbon and more.

ZEBs’s May Decarb Lunch is online and free! With so many of us working remotely, we would like to provide an opportunity for the building community to connect in a safe way, share ideas and stay inspired.
