【 摘 要 】

Ultra-low-energy buildings have attracted increasing attention particularly for ensuring a comfortable indoor climate in summer and in winter with ultra-low energy demand. To permit this, there are high requirements on various parameters such as building envelope structure, and emphasizes the importance of building energy-saving optimization design. However, most of the current optimization analysis of the influencing factors of the building load is based on actual buildings with fixed spatial factors. Few studies have comprehensively considered the influence of building envelope parameters and spatial factors on building load. Actually, different architectural spatial design factors such as length-width ratio, building standard layer area, floor height correspond to different analysis results. Therefore, this paper first analyzes the influence of architectural space design factors on building load. Based on this, the orthogonal test method is used to study the contribution rate of nine building envelope thermal parameters to building load changes. The study found that under the premise of different spatial design factors, the thermal parameters of the envelope structure have different effects on the building load. The results of this paper provide a basis for energy-saving design and development of ultra-low-energy buildings in hot summer and cold winter regions.
