This study evaluates the energy performance of ASHRAE Guideline 36–compliant control (ASHRAE 36 control) and reinforcement learning (RL)–based control through experimental field tests and a simulation study. Three field tests were conducted at Oak Ridge National Laboratory’s commercial building test facility in Oak Ridge, Tennessee: a baseline with a baseline conventional control, a test with ASHRAE 36 control, and a test with RL-based control. The selected ASHRAE 36 controls were trim and respond control, as well as variable air volume (VAV) box control. We compared the measured supply air temperature of the rooftop unit, VAV box supply air temperature, and VAV box supply airflow rate across the three test cases. The field data indicated that ASHRAE 36 controls operated as specified by ASHRAE Guideline 36. Based on these data, ASHRAE 36 control achieved a 45 % reduction in hourly averaged HVAC energy consumption compared with the baseline, and RL-based control achieved a 66 % reduction. These potential annual energy savings were confirmed using a calibrated whole-building energy model. Compared with the baseline, ASHRAE 36 control reduced HVAC energy consumption by 42 %, and RL-based control achieved a 54 % reduction. Furthermore, RL-based control reduced total HVAC energy consumption by 21 % more than ASHRAE 36 control.

使用现场测量对 ASHRAE 准则 36 控制和基于强化学习的控制的能源性能进行评估


本研究通过实验现场测试和模拟研究评估了符合 ASHRAE 准则 36 的控制（ASHRAE 36 控制）和基于强化学习 （RL） 的控制的能源性能。在位于田纳西州橡树岭的橡树岭国家实验室商业建筑测试设施进行了三项现场测试：基线常规对照、ASHRAE 36 对照测试和基于 RL 的对照测试。选定的 ASHRAE 36 控制装置是配平和响应控制，以及可变风量 （VAV） 箱控制。我们比较了三个测试用例中测得的屋顶单元送风温度、VAV 箱送风温度和 VAV 箱送风气流速率。现场数据表明，ASHRAE 36 控制措施按照 ASHRAE 指南 36 的规定运行。根据这些数据，与基线相比，ASHRAE 36 控制措施的每小时平均 HVAC 能耗降低了 45%，基于 RL 的控制措施减少了 66%。这些潜在的年度节能效果使用校准的整体建筑能源模型得到证实。与基线相比，ASHRAE 36 控制将 HVAC 能耗降低了 42%，基于 RL 的控制降低了 54%。此外，与 ASHRAE 36 对照相比，基于 RL 的控制将 HVAC 总能耗降低了 21%。
