Research on Key Technologies of Small House Type Ultra-Low Energy Consumption Residential Buildings

For ultra-low energy consumption buildings, passive mode is emphasized to realize ultra-low energy consumption and provide comfortable indoor environment. It mainly relies on the high-performance building enclosure, new air heat recovery, air tightness, adjustable sunshade and other building technologies, but the difficulty of realizing passive ultra-low energy consumption mainly lies in the technical suitability. How to meet the energy demand of heating and cooling under the condition of non mechanical, non energy consumption or less energy consumption through the reasonable design of key technologies. Based on the climate characteristics of Beijing, this paper studies the key technologies of ultra-low energy consumption buildings, and tries to make a positive exploration on the technology promotion of ultra-low energy consumption buildings.
