Residential and commercial buildings consume approximately 60% of the world’s electricity. It is almost impossible to provide a general definition of thermal comfort, because the feeling of thermal comfort is affected by varying preferences and specific traits of the population living in different climate zones. Considering that no studies have been conducted on thermal satisfaction of net-zero energy buildings prior to this date, one of the objectives of the present study is to draw a comparison between the thermal parameters for evaluation of thermal comfort of a net-zero energy building occupants. In so doing, the given building for this study is first optimized for the target parameters of thermal comfort and energy consumption, and, hence, a net-zero energy building is formed. Subsequent to obtaining the acceptable thermal comfort range, the computational analyses required to determine the temperature for thermal comfort are carried out using the Computational Fluid Dynamics (CFD) model. The findings of this study demonstrate that to reach net-zero energy buildings, solar energy alone is not able to supply the energy consumption of buildings and other types of energy should also be used. Furthermore, it is observed that optimum thermal comfort is achieved in moderate seasons.

提高居住者热舒适度的净零能耗建筑能耗优化

住宅和商业建筑消耗了全球约 60% 的电力。几乎不可能提供热舒适的一般定义，因为热舒适的感觉受到生活在不同气候带的人群的不同偏好和特定特征的影响。考虑到在此之前没有对净零能耗建筑的热满意度进行研究，本研究的目的之一是比较用于评估净零能耗建筑热舒适性的热参数。居住者。在这样做时，本研究的给定建筑物首先针对热舒适性和能源消耗的目标参数进行了优化，因此形成了净零能耗建筑。在获得可接受的热舒适范围之后，确定热舒适温度所需的计算分析是使用计算流体动力学 (CFD) 模型进行的。这项研究的结果表明，要实现净零能耗建筑，仅靠太阳能是无法满足建筑能耗的，还应使用其他类型的能源。此外，据观察，在温和的季节可实现最佳的热舒适性。
