This is a revised report from the initial Building energy codes issued in year 2008. IEA and UNDP joint report shares best practices and lessons learned among IEA member countries and non-IEA countries in improving energy efficiency in the building sector.

The objective is to limit pressures on global energy supply, improve energy security and contribute to environmental sustainability. Part of the IEA Policy Pathway series, Modernising Building Energy Codes to Secure our Global Energy Future sets out key steps in the planning, implementation, monitoring and evaluation stages. The Policy Pathway series aims to help policy makers implement the IEA 25 Energy Efficiency Policy Recommendations endorsed by IEA Ministers (2011).
