Applicability Analysis of Passive Building Energy Efficiency Technologies across Climate Zones

Abstract

With the continuous development of China’s economy, people’s awareness of environmental protection is gradually increasing. Passive building energy conservation is achieved by utilizing the ecological building design principles of natural climate resources to endow buildings with energy-saving natural characteristics. Therefore, it is greener and environmentally friendly, more conducive to the sustainable development of human living environment, and has become a direction actively advocated for building energy conservation. Analyze the applicability of six passive building energy-saving technologies, including passive solar heating, natural ventilation, heat storage walls, induction + night ventilation, direct evaporative cooling, and indirect evaporative cooling, based on the climate characteristics of typical cities in various climate zones in China, and compare the applicability of various passive building energy-saving technologies in each climate zone.
