Abstract

This paper analyzes the potential of natural resources to improve the indoor thermal environment in Chongqing through the statistical analysis of natural resources including solar energy, wind, water, and earth, etc. The building form, systems, and principle of usage of natural resources are briefly analyzed through the building site decision, building form design, and computer simulation, which will be the real reference for the design of building energy efficiency.
