This study seeks to evaluate the efficacy of several passive design strategies to reduce the risk of overheating in a Compressed Stabilized Earth Brick (CSEB) house situated in Johannesburg. The roof features CSEB masonry vaults and the walls were built from dry-stack (mortarless) masonry. The vaults were initially coated with maroon paint, which resulted in uncomfortably high temperatures during summer months. Several passive design strategies were considered to improve the thermal performance, and the effectiveness of each were assessed against the CIBSE TM52: 2013 overheating criteria. Surface shading and painting external surfaces white were especially effective at reducing the potential of overheating in the first-floor vaults. Ventilating the space in the late afternoon and evening reduced the period during which indoor operative temperatures exceeded T_max. An insulated ceiling proved effective at reducing the indoor temperature in early- and late-summer but had little impact on the severity of overheating during mid-summer.

本研究旨在评估几种被动设计策略的功效，以降低位于约翰内斯堡的压缩稳定土砖 (CSEB) 房屋过热的风险。屋顶以 CSEB 砌体拱顶为特色，墙壁由干式（无砂浆）砌体建造。拱顶最初涂有栗色油漆，导致夏季高温令人不安。考虑了几种被动设计策略来提高热性能，并根据 CIBSE TM52：2013 过热标准评估了每种策略的有效性。表面阴影和将外表面涂成白色对于减少一楼拱顶过热的可能性特别有效。_最大。事实证明，隔热天花板可有效降低夏初和夏末的室内温度，但对仲夏期间过热的严重程度几乎没有影响。
