| Summary: | There is an essential need to reduce energy consumption in building sector as it consumes about 40
percent of the world energy and causes environmental problems. About fifty percent of energy in the
building sector is used for heating, cooling and air conditioning purposes. Considering building
envelopes as particular building elements with many functions which its energetic function is the most
important one influencing building energy consumption, enhancing the thermal and energy efficiency
of envelopes would decrease energy consumption of the buildings. Building envelopes contain roofs,
external walls which are in touch with the outside environment and the floors on the ground. This
paper would review a brief history of envelopes evolution and introduce a categorization for the
envelopes based on different strategies for enhancing energetic function. A huge literature review on
building envelopes has been done to identify different techniques. The result is summarized in five
strategies as energy generation, cooling and heating, sun radiation control, and Thermal moderation
and adaptive. |
