Influence of residential building air tightness on energy consumption

Briefly presents the relevant standards, current research status and energy saving measures of residential building air tightness at home and abroad. Considering the needs of human health and energy saving, establishes the air tightness model and ventilation model of residential buildings. Analyses the energy consumption of heating and air conditioning system under different air tightness levels, different ventilation modes and different climate areas. Puts forward optimal air tightness and ventilation mode.
