Commercial new construction
By being a leader in energy management, we can assist with resources, technical assistance to building owners, developers and the design industry to create high-performance, and energy-efficient buildings.
A look at how owners, developers, and design teams of new commercial buildings have benefited from participating in the New Construction Program.
Thanks to strong interest from the development community in BC our program is currently fully subscribed.
When in market we offer design support for large buildings in the early stage of the design process that have potential electricity savings with at least 50,000 kWh per year.
The energy-efficient lighting system design offer is no longer available. As part of the whole building design offer, please reference the lighting calculator and reference guide.
Note: Effective May 1, 2015 all Whole Building Design project applications must comply with the updated program/modelling requirements referenced below.

This guide explores how the building industry in B.C. can meet the challenges of reducing energy use in buildings, in part by effectively accounting for the impact of thermal bridging.
Version 1.2 – September 2018
The BETB Guide V 1.2 expands the thermal performance catalogue (Appendix A and B) with additional data for a number of newly analyzed assemblies and details. This includes more cladding attachment systems, window interfaces, precast concrete interfaces, wood frame and brick veneer walls and other thermal mitigation systems. This version also has updates to some previous values. All new data sheets have been added in sequentially so all detail reference numbers from V1.1 are still valid.
Refer to the original version of the BETB Guide released in 2014 for sections related to energy savings and cost benefit analysis (Part 2) and market transformation (Part 3: Significance, Insights, and Next Steps). These documents are still relevant to current realities but are not materials that need to be referenced in everyday practice and have not been updated since the original version of the BETB Guide.

Version 1.1 – April 2016
Many details and assemblies were added to the thermal performance catalogue (Appendix A and B) of BETB Guide Version 1.1. The sections related to the cost benefit analysis and market transformation have been removed so that the new version focuses only on providing thermal performance data and how to utilize this information in everyday practice.

Version 1.0 – October 2014
Most practitioners will find PART 1 and Appendices A and B to be most useful. PART 1 outlines how to effectively account for thermal bridging. Appendices A and B provide a catalog of common building envelope assemblies and interface details, and their associated thermal performance data.
Researchers and regulators will be interested in PART 2 and PART 3, and Appendices C to E. They contain the cost-benefit analysis, and discussion on significance and further insights, of using this guide to mitigate thermal bridging in buildings.
