RESEARCH AND ANALYSIS ON INDOOR ENVIRONMENT DESIGN OF GYMNASIUM FROM THE PERSPECTIVE OF LOW ENERGY CONSUMPTION

The balance between thermal comfort and low energy consumption is very important in the design of indoor environment of gymnasium. Based on the analysis of the influencing factors of thermal comfort and energy consumption, combined with the key parameters of indoor environment design, this paper determines the main influencing factors, establishes the sensitivity analysis model, uses the analysis of variance method to measure the accuracy of the model, and uses the response surface method to analyze the significance level of each factor on energy consumption and the enthusiasm of the influence. Based on the average thermal comfort index (PMV), the concept of thermal neutral temperature is introduced, the influence of indoor humidity and other factors is integrated, and the influence of various factors on energy consumption and thermal comfort is quantified, so as to optimize the best scheme of interior design. Based on the perspective of low energy consumption, the optimal scheme 3 is the building scheme with low energy consumption and good thermal comfort. It finds that the optimal design method can save about 20% of the heat energy, and significantly improve the thermal comfort of the building personnel in different seasons. The research results can provide more accurate heat consumption prediction data for the whole design process.
