Research on Key Technology of Ultra-low Energy Consumption Buildings in Beijing

Ultra-low energy buildings focus on realizing ultra-low energy consumption mainly by virtue of passive mode and providing a comfortable indoor environment. Such buildings mainly rely on high-performance envelope, fresh air heat recovery, air tightness, adjustable shade and other building technologies to enable ultra-low energy consumption. However, the difficulty mainly lies in technical suitability. That is, how to meet the energy requirements of heating and cooling under the conditions of non-mechanical, no energy or less energy consumption through reasonable design of key technologies. Combining with the climate characteristics of Beijing, this paper studies the key technologies of ultra-low energy buildings and attempts to make active exploration on the technical advance of ultra-low energy buildings.
