Energy reporting and disclosure, also known as energy benchmarking, is the practice of measuring a building\u2019s 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\u2014bridging the gap between design-stage energy modelling and real-world outcomes.<\/p>\n
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.<\/p>\n
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<\/em>.<\/p>\n
