The average global cooling demand in non-residential buildings is expected to increase by over 275% between now and 2050. Controlled passive cooling is fundamental to successful operational performance of buildings and in mitigating of energy that would be consumed by mechanical systems. The aim of this study was to determine the resilience of different passive cooling control strategies in delivering optimal comfort and energy scenarios in both current and future extreme conditions, for low energy indoor office spaces. Simulations were conducted using a calibrated model of a nearly zero energy building using TRNSYS 17. The performance of ten passive cooling control strategies was simulated for climatic conditions in two representative cities, Dublin and Budapest. Each strategy used different combinations of passive cooling systems such as day-time ventilation, night-time ventilation and dynamic solar shading. The effect of static and adaptive indoor temperature set-points and a limit on external relative humidity was also investigated. The thermal comfort performance of each strategy was assessed by using standardised thermal comfort, overheating and overcooling metrics. Findings from the study show that passive control strategies maintained comfortable internal conditions between 57% and 95% of the occupied hours, without the need for mechanical cooling. The most resilient strategies were those that combined multiple measures. Passive control strategies were found to be resilient in the medium-term in Dublin, however, the same systems were not able to maintain comfortable conditions in Budapest in 2050. The use of an external relative humidity limit resulted in increases overheating incidences and failure of some overheating criteria. Based on the reductions in mechanical cooling requirements, it was concluded that there is regulatory need to consider the use passive control strategies in the design of buildings.

从现在到2050年，非住宅建筑的平均全球制冷需求预计将增长超过275％。受控的被动制冷是建筑成功运行性能以及减轻机械系统消耗的能源的基础。这项研究的目的是确定在低能耗室内办公空间中，在当前和未来的极端条件下，提供最佳舒适度和节能方案的不同被动冷却控制策略的弹性。使用TRNSYS 17使用接近零能耗建筑的校准模型进行了仿真。针对两个有代表性的城市都柏林和布达佩斯的气候条件，模拟了十种被动制冷控制策略的性能。每种策略都使用了被动冷却系统的不同组合，例如白天通风，夜间通风和动态遮阳。还研究了静态和自适应室内温度设定点以及外部相对湿度限制的影响。通过使用标准化的热舒适性，过热和过冷指标来评估每种策略的热舒适性能。该研究的结果表明，被动控制策略可将舒适的内部条件保持在占用时间的57％至95％之间，而无需进行机械冷却。最有弹性的策略是结合了多种措施的策略。在都柏林，中期发现被动控制策略具有弹性，但是，相同的系统无法在2050年保持布达佩斯的舒适状态。使用外部相对湿度限制会导致过热发生率增加，并导致某些过热标准失效。根据减少的机械冷却要求，得出的结论是，在建筑设计中需要在管理上考虑使用被动控制策略。
