“优势度”法在独院式住宅平面设计中的应用

Plan Design Strategy for Isolated House Based on Predominance Score

住宅平面设计多为直觉和感性设计,由此产生的设计方案往往在住宅的朝向、采光及节能等方面存在着不足,从而造成住宅使用功能方面的问题,这种现象在低密度住宅的设计中尤为突出。针对独院式、并联式、联排式等低密度住宅的平面布局特点,提出住宅内不同位置处依据朝向、自然采光及节能保温等因素的“优势度”概念,并根据房间不同朝向,自然光源数量及不同围护内墙数量等因素,分别为每一个区域赋于优势度分值。建议平面设计以各区域综合优势度排序为依据。该方法有助于建筑师将直觉和感性设计转为理性设计。具体案例应用表明了方法的适用性。

Plan design of residential building is usually based on intuition, so there are often shortcomings in room orientation, natural lighting, ventilation and energy saving, causing some problems in its function. A concept of Predominance Score is suggested for different locations of the building according to the room orientation, natural lighting, ventilation and energy saving. Based on the low -density characteristics of isolated house ,the suggested Predominance Score （PS） is assigned to each specific zone based on room orientation, amount of natural lighting sources and number of inner walls etc. Then, the plan design is carried out according to the order of PS. This strategy will help architects to make decision on technical analysis rather than on intuition. A case study shows the validation of the suggested strategy.
