一种自然通风办公建筑主动式立面的环境评价

主动式立面经常在建筑中应用以促进建筑通风，为了保证这个过程的有效性，主动式立面必须朝南，然而这样，太阳辐射就会穿过玻璃直射室内，夏热季节则需要借助遮阳设施来遮挡，这可能会导致室内采光达不到标准。另一方面，采用主动式立面的建筑倾向于提高蓄热性能来强化夜间蓄冷效果，结果可能导致声回响时间延长，干扰人的工作。本文对采用主动式立面的办公建筑室内光、声和热环境性能进行测试评价，初步分析结果表明，主动式立面的优点是能够通过被动方式利用太阳能，提供高质量的工作环境，而如何确保空气流动路径通畅，以及如何采取相应措施减少声回响时间值得关注。

Environmental Evaluation of an Active Facade in a Naturally Ventilated Office Building

An active facade is often used to promote the flow of air through a building. However in order to ensure that this process is effective the facade should face a southerly orientation. This means that not only solar energy is transferred across the glazing but in warm periods shading is needed which can produce an internal environment where the luminance distribution may not comply with current lighting requirements. Also such buildings tend to have a high thermal mass to promote the use of night cooling; one consequence of this type of design is that there is a tendency for high reverberation times which can be acoustically distracting. This paper reports the initial findings of an internal assessment of the day lighting, acoustic and thermal comfort conditions of such a building. The results have indicated that such designs are to be commended for their passive use of solar energy and can provide a high quality working environment, provided that care is taken to ensure that the air flow paths are maintained and reasonable precautions taken to reduce reverberation times.
