jailcd2023035: Research on Energy-Saving Technologies for External Windows of Residential Buildings in Hot Summer and Cold Winter Areas

Abstract

In recent years, with the development of China's economic level, environmental and resource issues have become more and more prominent. As the most active part of the heat exchange between the building and the outside world, the external windows of the building have been the focus of the issue of building energy efficiency. At present, existing residential buildings in hot summer and cold winter areas generally lack energy-saving measures, and the thermal insulation performance of external windows in the external envelope is poor, and the heat loss through external windows is large. Research into reducing the energy consumption of external windows has become a key focus of energy efficiency work in buildings in hot summer and cold winter regions. This study investigates the application of external windows in existing residential buildings in hot-summer and cold-winter areas, analyses the thermal performance parameters and problems of external windows in these areas, summarizes the energy-saving design techniques for external windows, and optimizes the design by combining the characteristics of residential buildings and climate in hot-summer and cold-winter areas. The study aims to provide practical ideas on the selection of external windows for residential buildings in hot-summer and cold-winter regions, in order to achieve a reduction in building energy consumption and promote the development of the green building sector.
