Building Technology Roadmap: ICCA

According to the International Energy Agency's Energy Technology Perspectives 2012 report, the building sector is directly or indirectly responsible for about 32% of global energy consumption and for 26% of global total end-use energy-related carbon dioxide (C02) emissions.

Huge amounts of energy -- over 970 million tons of oil equivalent in 2009 -- are required for space heating and space cooling in the global building stock due to heat gains and losses from building envelopes. The energy requirements and associated greenhouse gas (GHG) emissions are substantial in cold and hot climates alike. Overarching climate goals (reduction of GHG emissions by 80 to 95% by 2050) can only be reached with major contributions from the building sector.
