外窗尺寸对办公建筑采光影响因素研究

外窗作为建筑重要的外围护结构,不仅会影响建筑采光,同时,还会影响建筑照明、空调、供暖能耗。在相同外窗面积条件下,为获得更好的采光效果,可以在不增加空调及供暖能耗的前提下有效减少建筑的照明能耗,进而降低整体建筑能耗。通过计算机模拟分析办公建筑外窗尺寸对有效采光宽度、有效采光深度、有效采光面积的影响,总结出不同吊顶高度下的采光效果指标的查询图标,供外窗设计参考。     

Prospective techniques of effective daylight harvesting in commercial buildings by employing window glazing, dynamic shading devices and dimming control—a literature review

Over a few decades, daylighting has been perceived to possess good potential for energy conservation. In this perspective, there have been significant advances in research methodologies and technologies for optimizing energy consumption through daylight harvesting in commercial buildings. In light of this, a thorough understanding of the application of available technology is very important for daylighting practices for building energy management. The objective of this paper is to examine the status of published research on three key building parameters: window glazing area, dynamic shading devices, and daylighting controls playing a rule on energy conservation. This article may serve as a coherent literature survey that would provide better understanding of the subjacent issues and possibly rejuvenate research interest in this immensely potential field of energy engineering.

天然采光与人工照明的智能结合策略

以‘绿色照明‘为出发点,提出了一个天然采光和人工照明相结合的智能策略.选择一间典型的办公室为试验对象,用BP神经网络建立模型,根据室内天然光的照度水平,自动控制灯具调光输出和遮阳设备状态,从而实现工作区域恒照度的目标.实际应用中,一旦人工照明打开,能检测到的就是天然光和人工光的混合量,很难把天然光分量用设备检测出来,这给控制带来了一定的麻烦.因此提出了一个自适应神经模糊推理系统,用以根据室外的天然光照度来预测室内的天然光照度,作为BP网络的输入.实验数据表明,该方法能有效节约能源,并改善工作环境,提高工作效率.     

Optimum design and analysis of the application of the air slot on the building horizontal sun-shading board

The sun-shading board is an important way to improve the indoor thermal environment. And air slot is the critical component to improve ventilation effect of sun-shading board. It not only can promote heat dissipation of sun-shading board but also can improve ventilation effect of building window. The shading coefficient of shading board and vorticity influence of air slot are the main principles of designing configuration and size of air slot. The horizontal sun-shading board of residential building south window in Nanjing is the study object. The shading and ventilation effect of shading board with various configurations and size is analyzed quantitatively. And appropriate configuration and size are obtained on the basis of comprehensive consideration of various factors.

Deculverting: reviewing the evidence on the ‘daylighting’ and restoration of culverted rivers

We review published references on ‘deculverting’ (also known as ‘daylighting’) projects in the United Kingdom and internationally. The aim of the review was to assess the objectives of implemented projects and to establish where evidence exists for the purported social, economic and environmental benefits of deculverting. The outcomes highlight the need for collaboration to collate detailed information on such projects, to support the further development of evidence‐based policy. It is clear that deculverting schemes can indeed exert considerable positive impacts, including ecological benefits, reduced flood risks, recreation for local communities and a stimulus for regeneration, but that the evidence for these impacts is sparse. We conclude that improvements in policy will help to maximise these opportunities, by encouraging the implementation of good practices.
