Abstract

With economic development, social progress, living standards have gradually improved. Artificially create a comfortable indoor stir up trouble, will inevitably lead to dramatic building energy consumption, building energy consumption as an important part of a country's total energy consumption, energy conservation has become an important breakthrough. To make the buildings from the architectural level to improve building indoor thermal environment to maximize, to achieve the greatest degree of building energy efficiency, promote low-carbon society today has become a top priority. Building energy consumption of hot summer and cold winter region is the focus of the object, and Chongqing due to the special nature of its geographical situation, control of indoor thermal environment in the region is particularly important, it is based on the above purpose, the hot summer and cold winter areas Chongqing targeted understand the Chongqing area residential construction indoor heat and moisture status and building basic characteristics, the degree of importance of the environment and the Laboratory of Heat and Moisture architectural level impact and impact factors, the design and construction of energy-saving building layout priority considered object to provide some support. The first Chongqing climate conditions as a starting point, the analysis of its architectural outdoor hot wet environment, come to Chongqing hot and humid summer, winter cold and intolerable characteristics. Building indoor thermal environment and building basic information in an outdoor environment, research, research results found in harsh outdoor environments, the winter and summer indoor natural adjustment of status under the indoor thermal environment is urgent need to improve the and the architectural layout of the area is slightly messy, building layout, construction of indoor thermal environment improvement effect is a way of reasonable evaluation of whether the layout of the building. Indoor thermal and humid environment in order to clear the building level indoor main influencing factors and the degree of importance of the heat and moisture environment, this paper based on the survey questionnaire data and building basic information, using factor analysis method, basic information on the winter and summer building its indoor thermal environment analysis of the situation, the eight basic factors of influence, the summer extracted five main factors, instead of the original eight indoor thermal environmental impact factors and with 5 main factors, its efficiency up to 85.527%; winter extracted four main factors instead of the original eight indoor thermal environmental impact factors, and these four main factors, the efficiency up to 82.924%; and the weight coefficient of each factor in the factor analysis a major factor in the order of importance. Then, using a single-factor analysis method to the analysis of the factors at different levels of indoor thermal environment to find out the main factors analyzed: whether it is winter or summer, the building envelope structure, window type, window open area, different window toward and building floors of indoor thermal environment, research data and draw differences in the degree of subjective and objective evaluation of the room staff. Window toward the analysis found that the differences between the different orientations window there are strong or weak, by comparison of the data analysis, respectively, to find out the differences between winter and summer, two windows toward building indoor thermal environmental impact from the strong to recommended by the order of the weak, and Chongqing region toward the window. Therefore, based on the above analysis, building energy efficiency is growing concern today, from the architectural level to do building energy efficiency and improving indoor thermal environment, is one of the important tasks of the current study, the research results of the above building energy efficiency and building design layout provides important support.
