Year-round high temperatures and humidity in the Tropics, coupled with poor design decisions and climate change, can cause indoor environments to overheat, affecting health and increasing energy demand and carbon emissions. Passive cooling could help lower the indoor overheating risk. Given the gap in the relative influence of passive cooling design strategies on lowering the indoor overheating risk in tropical locations, this study investigated their impact in two warm tropical cities (i.e., Tegucigalpa and San Pedro Sula), considering both current and future climate scenarios, with a total of 3840 thermal simulations performed. Indoor overheating risk in apartment-type dwellings was assessed using two metrics (i.e., hours of exceedance and the indoor overheating degree), and considering fixed and adaptive thermal comfort limits. Simulation results show that the overheating risk can be significantly lowered in these tropical contexts using solely passive cooling strategies as heat adaptation measures. Multivariate regression models demonstrate that natural ventilation, wall absorptance, the solar heat gain coefficient, and semi-outdoor spaces have the greatest impact in lowering the risk in vertical social housing projects. This study emphasizes the importance of passive cooling and overheating protection design strategies in tropical building codes and building design while considering current and future risk.

热带地区终年高温高湿，加上糟糕的设计决策和气候变化，会导致室内环境过热，影响健康，增加能源需求和碳排放。被动冷却有助于降低室内过热风险。鉴于被动冷却设计策略对降低热带地区室内过热风险的相对影响存在差距，本研究调查了它们对两个温暖热带城市（即特古西加尔巴和圣佩德罗苏拉）的影响，同时考虑了当前和未来的气候情景，共进行了 3840 次热模拟。公寓式住宅的室内过热风险使用两个指标（即超标小时数和室内过热度）进行评估，并考虑固定和自适应热舒适限制。模拟结果表明，在这些热带环境中，仅使用被动冷却策略作为热适应措施可以显着降低过热风险。多元回归模型表明自然通风、墙体吸收、太阳能得热系数和半户外空间对降低垂直社会住房项目的风险影响最大。本研究强调了被动冷却和过热保护设计策略在热带建筑规范和建筑设计中的重要性，同时考虑了当前和未来的风险。
