They include (1) Building codes and Regulation, (2) Appliance and equipment standards and labels, (3) Building rating, labelling, and disclosure, (4) Building component standards and labels. A second set of priority areas of action is addressed by the report as “enabling collaboration areas" includes (1) Data availability and quality and (2) Education and capacity building. A third relevant category to be considered is “Metrics”, which refers to the importance of defining appropriate standards metrics.
