Thermal comfort is a critical component of indoor environments, especially in schools where learning is the main objective. However, thermal comfort comes at a price that many schools are unable to afford. Therefore, it is critical to determine a method to lower the energy costs of a building while still maintaining occupant thermal comfort. The objective of this study is to investigate how three indoor environmental parameters of air speed, humidity, and air temperature influence energy and thermal comfort in classroom environments. We employed a multi-objective optimization method that considers all three thermal parameters in the design and operation of a classroom. This method is demonstrated for three distinct climate locations (very hot and humid, cold and humid, warm and marine). Overall, our findings demonstrate significant energy savings from 1.3 to 9.1 kWh/year/m² for cases where energy reduction is achieved. These values are for cases where the total annual number of hours that more than 10% of people are dissatisfied in a space are 0 to 42 in Miami and San Francisco and 26 to 49 in Boston. This translates to a cost savings of $3,000 to $12,800 per year for the entire building at current market rates. Note that for all locations, there were also cases where the number of hours that more than 10% of people were dissatisfied were reduced from the baseline value while still reducing energy use. This optimization framework shows promise for building mechanical designers seeking to maintain increased levels of thermal comfort throughout the year while lowering energy use.

热舒适是室内环境的重要组成部分，尤其是在以学习为主要目标的学校中。然而，热舒适的代价是许多学校无法承受的。因此，确定一种降低建筑物能源成本同时仍保持住户热舒适度的方法至关重要。本研究的目的是调查风速、湿度和气温这三个室内环境参数如何影响教室环境中的能量和热舒适度。我们采用了一种多目标优化方法，该方法考虑了教室设计和操作中的所有三个热参数。该方法适用于三个不同的气候位置（非常炎热潮湿、寒冷潮湿、温暖海洋）。全面的，²对于实现节能的情况。这些值适用于迈阿密和旧金山超过 10% 的人对空间不满意的年度总小时数为 0 到 42 以及波士顿为 26 到 49 的情况。按当前市场价格计算，这意味着整个建筑每年可节省 3,000 至 12,800 美元的成本。请注意，对于所有地点，也有超过 10% 的人不满意的小时数从基线值减少的情况，同时仍然减少了能源使用。该优化框架为寻求在全年保持更高水平的热舒适度同时降低能源使用的建筑机械设计师展示了前景。
