本研究使用微型建筑的一阶近似来研究决定热容（ITC）与蓄热管理（TSM）的增加如何在天气条件相对温和的地区（如美国东南部）降低能耗的主要因素。在这项研究中，ITC是通过建筑围护结构中嵌入的大型储罐和管道之间的水循环来实现的。尽管ITC导致建筑物热响应的主导时间常数较大，但通过TSM对附加电容的自适应分配和控制显着提高了额外电容的效益。本文比较了微型建筑的两种一阶模型：一个参考案例模型与建筑相关的单个集总热容，另一个模型与建筑的电容加上水系统的电容。结果表明，ITC/TSM系统通过减少制冷系统和供暖系统的运行时间，降低了建筑物的调节成本。5月至9月，空调运行时间平均减少70%，10月至4月，供暖系统运行时间平均减少25%。
This study uses a first-order approximation of a micro-building to investigate the major factors determining how increased thermal capacitance (ITC) with thermal storage management (TSM) can reduce energy consumption in locations with relatively mild weather conditions such as the southeastern part of the United States of America. In this study, ITC is achieved through water circulation between a large storage tank and pipes embedded within the building envelope. Although ITC results in a larger dominant time constant for the thermal response of a building, an adaptive allocation and control of the added capacitance through TSM significantly improves the benefits of the extra capacitance. This paper compares two first-order models for a micro-building: a reference case model with a single lumped thermal capacitance associated with the building, and another model, with the building’s capacitance plus the capacitance of the water system. Results showed that the ITC/TSM system reduced the cost of conditioning the building by reducing the operating time of both the cooling and the heating systems. May through September, the air conditioning operating time was reduced by an average of 70%, and October through April, the operation of the heating system was reduced by an average of 25%.
