Research On Energy Saving Design Of External Windows Of Residential Buildings In Yancheng

Building industry’s energy consumption is growing sustained and rapidly, energy conservation is of great urgency, energy saving has become an important strategy for sustainable development of China. Outside window energy efficiency is an important part of building energy consumption, improving and enhancing its consequence is the key to raising the level of overall building energy efficiency.This thesis based on the climate and geographical location of Yan Cheng areas outside the main factors combined with energy-efficient windows, respectively, from window to wall ratio in accordance with local laws and regulations, the heat transfer coefficient, shading coefficient, air tightness, outside of the window, the window frame material, external window toward a comprehensive analysis, and give the specific and feasible energy efficiency in residential buildings of the outside window design measures of Yan Cheng areas, applied to engineering practice, and achieved good results. Thus, with the popularity of building energy gets deeper and deeper, promote the outside window product standardized, systematic and industrialization will be the future trend of development.
