About the report

This report examines how the development of the 2020 model national energy codes navigated this tension between a minimum standard building energy code and an implicit goal within the PCF to promote market transformation towards highly efficient and low-carbon buildings.

While the 2020 model building codes will introduce significant changes and a path towards a net-zero energy-ready standard, there is also evidence that the institutional inertia associated with the traditional ways building codes are developed held back the development of the model building code required for a net-zero emissions future.
