Existing building energy standards in the United Nations Economic Commission for Europe (UNECE) region vary from voluntary guidelines to mandatory requirements, which may apply to one or many building types. Their development is typically a complex decision-making process that can involve any combination of participants. Building energy standards are difficult to classify and the standards that are stringent for one country may be ineffective in another country, depending on climate conditions, occupant behavior, existing building stock, and construction practices.
In response to this challenge and to strengthen understanding about the status of deployment and implementation of energy efficiency standards in buildings in the UNECE region, Committee on Housing and Land Management (CHLM) and Committee on Sustainable Energy (CSE) made a decision to develop a study on “Mapping of existing energy efficiency standards and technologies in buildings in the UNECE region” with the objective to identify which energy efficiency standards in buildings the UNECE Member States are using. The objective of this study is also to evaluate the most effective policies and highlight the best practices to help nations learn from one another and achieve greater savings. This report presents the results of this study and takes a look at the building energy standards in the UNECE region to determine which countries are embracing energy efficiency through highly effective building energy codes.
