  • 2. © OECD/IEA/UNDP 2013 Building energy code is the first IEA EE policy recommendation for buildings The IEA recommends in its 25 Energy Efficiency Policy Recommendations that governments “require all new buildings, as well as buildings undergoing renovation, to be covered by energy codes and meet minimum energy performance standards (MEPs) that aim to minimise life-cycle costs. Energy codes and MEPs should be enforced, regularly strengthened and take a holistic approach that includes the building envelope and equipment”

  • 7. © OECD/IEA/UNDP 2013 Building energy codes: the policy instrument to reduce buildings’ energy consumption 1970 • Prescriptive energy codes (trade-off could be made between energy performance of the envelope and those of HVAC systems) 1990 • Model energy codes (called also performance code in some countries) (energy requirements vary from one reference building to another) 2000 • Overall performance code (integrated design & holistic approach, standard energy performance requirements for each building type in each climate zone)
