Research on envelope design of ultra low energy consumption passive building in severe cold area

Abstract

At present, the common solid clay brick structure is widely used in residential building walls, which leads to higher indoor humidity, serious energy loss, waste of economy, environmental pollution and lower people’s comfort. The passive technology of ultra-low energy consumption can improve the insulation performance of the enclosure, reduce the energy consumption of heating and improve the comfort of the owner, and finally achieve the goal of energy saving of low energy consumption buildings in the cold area.
