Energy consumption analysis of passive buildings in the Yangtze River Delta based on PKPM-PHEnergy simulation

Abstract

The Yangtze River Delta region is characterized by hot summer and cold winter, mild climate in spring and autumn, significant precipitation in plum rain season, high relative humidity throughout the year and relatively sufficient light and heat. In this climate environment, people use a large number of air conditioners to improve the indoor comfort of buildings, which also greatly increases the building energy consumption. Combined with the natural environment and human economic characteristics of the Yangtze River Delta, this paper simulates the energy consumption of passive buildings, and the significant improvement of energy efficiency fully explains the applicability of developing passive buildings in the Yangtze River Delta.
