This paper focuses on how the existing sealed office typology can adapt to a warming world while minimizing the high energy demand for space cooling, through , by adjusting the cooling temperature profile towards the average human circadian rhythm to mitigate heat stress during times of heightened thermal sensitivity. This concept is explored through a study in which we compared the effects of , constant cooling, and no cooling on the core body temperature of 21 participants as well as a thermal dynamic simulation of 270 office space configurations under the same cooling profiles, comparing the total energy demand, peak loads, and overall hours of discomfort. The results of the study suggest the different conditioning profiles have no direct impact on the overall change in core body temperature throughout the day (difference < 0.04 K) but do influence the overall range throughout (from 0.37 K under constant cooling to 0.53 K under ). Additionally, there is no clear correlation between elevated indoor temperatures and CBT during the morning hours, questioning the necessity and effectiveness of pre-lunch cooling. This is underlined by the simulation findings, which reveal a non-linear relationship between savings in cooling demand and a decline in thermal comfort, with a 51.3 % reduction in ideal cooling energy demand and a 25.2 %–36 % increase of Over-Temperature-Kelvin-Hours, from a steady state cooling profile to a profile of . The results of the study and simulation challenge traditional cooling standards and highlight the need for a balance between minimizing thermal discomfort and the necessary cooling energy demand.

动态冷却——一种时间敏感的热调节概念，可减少办公楼的冷却能源需求


本文重点讨论现有密封办公室类型如何适应变暖的世界，同时最大限度地减少空间冷却的高能源需求，通过将冷却温度曲线调整为平均人类昼夜节律，以减轻热敏感度升高期间的热应激。通过一项研究探索了这一概念，在该研究中，我们比较了持续冷却和不冷却对 21 名参与者的核心体温的影响，并对相同冷却曲线下的 270 个办公空间配置进行了热动态模拟，比较了总冷却温度。能源需求、峰值负载和总体不适时间。研究结果表明，不同的调节模式对全天核心体温的总体变化没有直接影响（差异 < 0.04 K），但确实影响整个范围（从恒定冷却下的 0.37 K 到 0.53 K） ）。此外，早晨室内温度升高与 CBT 之间没有明显的相关性，这对午餐前降温的必要性和有效性提出了质疑。模拟结果强调了这一点，模拟结果揭示了冷却需求节省与热舒适度下降之间的非线性关系，理想冷却能源需求减少了 51.3%，而过温增加了 25.2%–36%。开尔文小时，从稳态冷却曲线到 的曲线。研究和模拟的结果挑战了传统的冷却标准，并强调需要在最大限度地减少热不适和必要的冷却能源需求之间取得平衡。
