The application of advanced materials in energy conservation is mostly among the urgent issues worldwide. In this context, nanosilica aerogel has received growing attention in the last decade due to its remarkably lower thermal conductivity. Aerogel panels laminated to drywall boards initiated to be used in substantially the energy sufficient buildings. Nevertheless, the greatest and most promising application of silica aerogel appears to be in substantially insulating glazing systems. The present research has concentrated on evaluating the energy performance of the nano aerogel glazing if implemented to the El-Dakahliya governmental headquarters building located in Mansoura city in Egypt, compared with single-glazed windows (base case) and double-glazed windows. The modeling was carried out in Autodesk Revit, and the process of energy performance simulation was carried out by Autodesk Ecotect Analysis by adopting the weather data of Mansoura. The results show that the nano aerogel glazing system succeeds in conserving approximately 19% in the annual energy consumption for a set-point temperature band of 19–27°C. The paper attempts to present significant research especially in studied country. Selected category of buildings may add more originality in term of implementation scope.

走向埃及的节能政府建筑物：研究纳米气凝胶玻璃对能源性能的影响

先进材料在节能中的应用主要是世界范围内的紧迫问题。在此背景下，由于纳米二氧化硅气凝胶的热导率显着降低，因此在过去十年中受到越来越多的关注。层压到干墙板上的气凝胶板开始用于基本上能量充足的建筑物。然而，二氧化硅气凝胶的最大和最有希望的应用似乎是在基本上隔热的玻璃窗系统中。目前的研究集中在评估纳米气凝胶玻璃的能量性能，如果将其应用于埃及曼苏拉市的El-Dakahliya政府总部大楼，则与单层玻璃窗（基本情况）和双层玻璃窗相比。建模是在Autodesk Revit中进行的，能源性能模拟的过程是通过Autodesk Ecotect Analysis采用Mansoura的气象数据进行的。结果表明，在19-27°C的设定温度范围内，纳米气凝胶玻璃窗系统成功地节省了约19％的年能耗。本文试图提出重要的研究，特别是在被研究的国家。选择的建筑物类别可能会增加实施范围的独创性。
