Building energy efficiency has been identified as a cost-effective opportunity to reduce energy consumption and greenhouse gas emissions and a variety of policies are being implemented to harvest this efficiency potential. However, there are growing concerns about a gap between predicted or expected energy consumption levels in buildings and the actual measured energy consumption in...

The energy agenda under the G20 Presidency of Japan focuses on the theme of “accelerating the virtuous circle of environmental protection and economic growth by innovation”. Through the Energy Transitions Working Group (ETWG) and Environment Senior Officials Meeting, G20 countries are working together to progress energy transitions that achieve “3E+S”: energy security, economic efficiency, and...

This presentation was delivered for the conference of Behaviour Change for Energy Efficiency: Opportunities for International Cooperation in the G20 and beyond, Paris.

Building energy efficiency policies are an important tool in addressing energy and climate policies. There has been tremendous technical and policy activity in recent years aimed toward improving building energy performance, with a focus on getting to very low energy buildings and targeting “zero” energy or emissions buildings. A variety of governments have established ambitious...

The National Development and Reform Commission of China (NDRC) guided the China Quality Certification Center (CQC) to develop a China TOP TENs Best Energy Efficient Practices list to highlight energy savings practices for the China’s buildings sector. The list covers a broad range of building practices including commercial and residential. Each practices have been weighted...
