Season 1 Episode 3

Recorded at Past Event: May 28 @ 12:00 pm – 1:00 pm


The Province’s CleanBC Plan 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 we 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.
