This report provides an overview of the IPEEC Building Energy Efficiency Taskgroup (BEET) project on opportunities for international collaboration on building energy codes amongst the major economies represented in the MEF and G20 (known as the BEET 3 project). Specifically, the BEET 3 project focused on code implementation and compliance activities critical to realising the energy, financial, and climate benefits of building energy codes. Here, implementation refers to the establishment of administrative structures to put the code into practice and compliance refers to the adherence of a building to the provisions of the code. Effective implementation and compliance include a number of interconnected elements, including training and awareness programmes; building plan review and site inspections; supportive infrastructure such as software tools to check designs; meaningful penalties for non-compliance; and building material testing, rating, and labelling systems that allow for quick assessment of whether materials meet code-approved design requirements.
National and subnational governments are ultimately responsible for adopting and implementing building energy codes. Where appropriate, international collaboration can play a critical role in helping governments to advance their own priorities, through the sharing of policy best practices, improving analytical capabilities, and providing other resources that accelerate and maximise the benefits of building energy codes.
