Energy reporting and disclosure, also known as energy benchmarking, is the practice of measuring a building’s energy use over time and comparing its performance to similar buildings. For new construction, it offers a way to assess whether a building performs as intended once it’s occupied—bridging the gap between design-stage energy modelling and real-world outcomes.
Unlike energy code compliance, which relies on simulations conducted before construction, post-occupancy reporting and disclosure reveals how a building actually operates. It can help identify inefficiencies, inform performance improvements, and support long-term planning for retrofits and emissions reductions.
Because energy reporting and disclosure requires at least 12 months of utility data, it applies after a building is operational. This means it cannot be used to regulate the construction phase, but local governments can still require energy performance reporting after a defined period of occupancy. Doing so supports both climate targets and asset management goals, while staying within the limits of the Building Act.
To support implementation, local governments can refer to the Step-By-Step Guide: Supporting Local Governments in British Columbia to Implement Energy Benchmarking, which provides detailed guidance on program design, data access, and stakeholder engagement.
