IEA-UNDP report shows how to modernise building codes
21 August 2013
A new report by the International Energy Agency and the United Nations Development Programme shows how building codes can be modernised with the aim of limiting pressure on global energy supply, improving energy security, and contributing to environmental sustainability.
Buildings are the largest consumers of energy worldwide and will continue to be a source of increasing energy demand going forward. Globally, the building sector’s final energy consumption doubled between 1971 and 2010 to reach 2794 million tonnes of oil equivalent (Mtoe), driven primarily by population increase and economic growth. Under current policies, the global energy demand of buildings is projected by the IEA experts to grow by an additional 838 Mtoe by 2035 compared to 2010.
The challenges of the projected increase of energy consumption due to the built environment vary by country. In IEA member countries, much of the future buildings stock is already in place, and so the main challenge is to renovate existing buildings stock. In non-IEA countries, more than half of the buildings stock needed by 2050 has yet to be built.
Against this backdrop, the IEA and the United Nations Development Programme (UNDP) partnered to analyse current practices in the design and implementation of building energy codes. The aim is to consolidate existing efforts and to encourage more attention to the role of the built environment in a low-carbon and climate-resilient world.
The new report, Modernising building energy codes to secure our global energy future, seeks to share lessons learned between IEA member countries and non-IEA countries, the report sets out key steps in planning, implementation, monitoring and evaluation of building codes.
The new report is part of the IEA’s Policy Pathway series, which aims to help policy makers implement the IEA 25 Energy Efficiency Policy Recommendations endorsed by IEA Ministers 2011.
