窗墙比对传统民居能耗与天然采光影响的探讨

| 摘 要： | 苏州民居作为中国江南地区传统民居，由于数量繁多、建造年代久远等原因，室内舒适度差，建筑能耗高，目前对于这些传统民居建筑的节能改造和利用仍有不足。窗户作为建筑外立面一部分，窗墙比不仅影响室内天然采光，也关系到建筑室内的能耗。本文以苏州市过云楼陈列馆的南向窗为研究对象，采用参数化模拟工具ladybug，探讨两种形制的窗户在不同窗墙比条件下对建筑能耗与天然采光的影响。结果表明：1)形制二的窗户能耗略大于形制一，且二者窗墙比在接近50%时，室内能耗变化趋于不变或减少；2)两种形制的窗户在窗墙比达到25%时已经达到采光要求。考虑到原民居改造后做陈列馆之用，并无特别的采光需求，南向窗墙比采用25%为宜。 |

Discussion on the Influence of Window-wall Comparison on Energy Consumption and Natural Lighting of Traditional Houses
School of Architecture and Urban Planning, Suzhou University of Science and Technology, Suzhou 215009, China
| Abstract: | As a traditional residence in the Jiangnan region of China, Suzhou houses are still insufficient for energy-saving transformation and utilization of these traditional residential buildings due to a large number and a long period of construction, poor indoor comfort and high building energy consumption. As a part of the façade of the building, the window-to-wall ratio not only affects the natural lighting of the interior, but also relates to the energy consumption of the building. This paper takes the south-facing window of Suzhou Guoyunlou Exhibition Hall as the research object, and uses the parametric simulation tool ladybug to discuss the effects of the two types of windows on building energy consumption and natural lighting under different window-to-wall ratios. The results show that: 1) the energy consumption of the window of shape 2 is slightly greater than that of shape 1, and the window-to-wall ratio of the two is close to 50%, the change of indoor energy consumption tends to remain unchanged or decrease; 2) The windows of the two shapes have reached the lighting requirements when the window-to-wall ratio reaches 25%. Considering that the original house is used as a showroom after renovation, there is no special lighting demand, and the south-facing window wall is 25% more appropriate. |
