ABSTRACT The present study has focused on the impact of location and deadband (range of thermostat setpoints for cooling and heating) on the energy performance and economics of nano granular silica aerogel (nanogel) glazing in a multi-storey office building, by considering 26 climatic locations of Saudi Arabia. The selected cities were classified according to the cooling degree days (CDD) and outdoor dry bulb temperature (DBT), as warm, moderately hot, hot, and very hot, and the results were generalized with respect to these climatic zones. The building model was built in Autodesk Revit (2015), and the energy simulation was performed by Ecotect (2011) in two cases: (i) insulated wall and roof, and DG window and (ii) insulated wall and roof, and nanogel glazing. The results show that the location and deadband have crucial impact on the energy performance and economic viability of nanogel glazing. The energy-saving potential and payback period of replacing DG window by nanogel glazing are attractive for cities with higher DBTs and CDD, compared to those with lower DBT and CDD. For all the climatic zones studied, the benefit of replacing DG window by nanogel glazing could be achieved for a specific deadband of 20–24°C.

位置和死区对沙特阿拉伯办公楼纳米气凝胶玻璃能效的影响

摘要 本研究的重点是位置和死区（用于冷却和加热的恒温器设定值范围）对多层办公楼中纳米颗粒二氧化硅气凝胶（纳米凝胶）玻璃窗的能源性能和经济性的影响，通过考虑 26 气候沙特阿拉伯的位置。所选城市根据冷度日数 (CDD) 和室外干球温度 (DBT) 分为暖、中热、热和极热，结果对这些气候带进行了概括。建筑模型在 Autodesk Revit (2015) 中构建，能量模拟由 Ecotect (2011) 在两种情况下进行：(i) 隔热墙和屋顶，DG 窗和 (ii) 隔热墙和屋顶，以及纳米凝胶玻璃. 结果表明，位置和死区对纳米凝胶玻璃的能量性能和经济可行性具有至关重要的影响。与 DBT 和 CDD 较低的城市相比，纳米凝胶玻璃替代 DG 窗的节能潜力和投资回收期对 DBT 和 CDD 较高的城市具有吸引力。对于所有研究的气候区，可以在 20-24°C 的特定死区中实现用纳米凝胶玻璃代替 DG 窗的好处。
