BC Building Code 2018 Revision 2

Effective December 12, 2019

Revision 2 of the BC Building Code 2018 has been approved and takes effect December 12, 2019. Revision 2 includes three changes to the BC Energy Step Code requirements.

Change 1 – Part 9 Residential Buildings

There will now be two additional options to address building envelope performance requirements (sometimes referred to as ‘targets’ or ‘metrics’): revised TEDI requirements or a percent-better approach. Thermal Energy Demand Intensity (TEDI) requirements will remain the same, however Revision 2 will allow builders in colder parts of a climate zone to adjust their TEDI based on the Degree Days Below 18C (HDD) of their project location, rather than use a single value for the entire climate zone. Alternately, builders using the EnerGuide approach will have the option of demonstrating a percentage improvement of the annual space heating demand over the reference building. This is based on a similar approach being considered for the model National Building Code.

Change 2 – Part 3 Buildings Outside Climate Zone 4

The BC Energy Step Code has adjusted requirements for Total Energy Use Intensity (TEUI) and Thermal Energy Demand Intensity (TEDI) that better reflect colder climate conditions.

Change 3 – Part 3 Buildings: Some Group A and Group B Occupancies

Preliminary BC Energy Step Code requirements for hospitals, care centres, schools, recreation centres, libraries and colleges have been introduced, which establish a Step 1 requirement (energy modelling conforming to Part 8 of the National Energy Code for Buildings (NECB) and air leakage testing will be required) for these building types. At this time, specific energy intensity requirements are not included for these buildings.

As with previous BC Energy Step Code requirements, these are voluntary measures and are subject to adoption by participating jurisdictions.

BCBC 2018 – Public Review of Proposed Changes

Public Review Period: June 28, 2019 – August 23, 2019

The Building and Safety Standards Branch invites code users, industry, and partners to participate in a public review to provide feedback on proposed changes to the BC Code, including the BC Energy Step Code.

2019 Local Government Step Code Readiness Survey

Each year, the Energy Step Code Council surveys local government staff to get a sense of awareness and readiness of the standard in communities across the province. The 2019 edition of the survey is now open and closes March 22. The Community Energy Association administers the survey with support from BC Housing.

If you are a local-government building official, planner, energy and/or sustainability manager, facilities manager, or senior manager, this one’s for you. We’ll share the final report on this website when it becomes available.

2018 Metrics Update: Now Approved

The  changes described here as the ‘2018 Metrics Update’ were approved with minor modifications and took effect December 10, 2018 when the 2018 BC Building Code came into effect. They are part of Revision 1 of the 2018 BC Building Code.

2018 Metrics Update

At its September 19, 2018 meeting, the members of the Energy Step Code Council endorsed the following proposed changes to the BC Energy Step Code metrics, for consideration by the Ministry of Municipal Affairs and Housing.


The Energy Step Code Council is recommending a number of extensions and minor improvements to the BC Energy Step Code that will allow more communities to participate in the transition to net-zero energy ready buildings. Collectively, we refer to these proposed changes as the 2018 Metrics Update.

At a high level, the 2018 Metrics Update aims to accomplish three goals:

  • It will ensure builders can reach the Upper Steps — Steps 4 and 5 for homes and other simple buildings — in colder climates.
  • It will correct a part of the standard in which certain large single-detached homes could potentially use more energy than those built to the minimum requirements of the BC Building Code.
  • It will make the BC Energy Step Code available to communities outside southwestern BC that may wish to use it to incentivize and/or require larger and more complex high-performance buildings.

The 2018 Metrics Update is just that—an update. The fundamentals of the regulation remain unchanged. We’ve heard loud and clear that industry needs predictability and consistency. This update is part of our commitment to supporting communities and builders who want to put the standard to work. It will make the BC Energy Step Code easier to implement and more widely available.

The Council prepared a summary document (PDF) that outlines the changes and their anticipated impacts on stakeholders. Eight companion documents (available below) provide details of the proposed changes for Part 3 and Part 9 buildings for each Climate Zone.

A full costing analysis of the proposed changes is available in an updated 2018 Metrics Research Report from BC Housing.

If adopted, these recommendations would likely take effect in December.
