Energy Efficiency on Buildings is a necessity

Buildings are the largest consumers of energy worldwide and will continue to be a source of increasing energy demand in the future. Globally, the sector’s final energy consumption doubled between 1971 and 2010 to reach 2 794 million tones of oil equivalent (Mtoe), driven primarily by population increase and economic growth. 

Under current policies, the global energy demand of buildings is projected to grow by an additional 838 Mtoe by 2035 compared to 2010 (IEA International Energy Agency), which is equivalent to the total current energy demand of the buildings sector of the United States and China combined ! 

Buildings will therefore add substantial pressure on primary energy supply, if further policy action is not taken at a global level to improve their efficiency.
