Energy-saving Renovation Technology Studies of Existing Residential Building in the Hot Summer and Cold Winter Summer Zone

摘要

The hot summer and cold winter zones are some of the key national construction energy conservation zones. In this paper, we analyzed the outside environment in the hot summer and cold winter zones and its influence on heat loss in an existing residential building. We further explored and analyzed major elements of residential outdoor environmental design, including water and vegetation. Through mathematical calculations, graphic analysis and logical reasoning, this article gives suggestions for residential energy-efficient outdoor environment-transforming technologies and methods.
