Recent simulation-based studies have indicated that Economic Model Predictive Control (EMPC) of space heating systems can exploit the thermal mass in residential buildings for demand response (DR) purposes in district heating systems. However, there is a lack of studies on residents’ perception and acceptance of the fluctuating indoor air temperature behaviour inherent in EMPC of space heating. This paper reports on a case study featuring the residents of three one-story houses located in Denmark. The houses were equipped with technology enabling remote actuation of radiator thermostats and collection of various indoor environmental data. Four different temperature boost interventions mimicking the typical behaviour of EMPC of radiators were executed while a mixed-methods triangulation design, employing questionnaires and semi-structured interviews, was used to collect subjective data. Data showed that residents accepted the behaviour but only after the benefits of the EMPC were explained. The acceptance was motivated by either the prospect of saving money, environmental benefits, or a combination of both. The results thereby indicate that explaining the benefits of EMPC is important if residents are to abandon their current preferences and practices in favour of an EMPC concept. The explanation should consider the diversity in current preferences, expectations, and level of technological pre-knowledge. In addition, the paper also reports on a range of findings related to technical aspects of realising EMPC in practice.

居民热舒适度和对空间采暖高峰转移态度的混合方法案例研究

最近基于仿真的研究表明,空间供暖系统的经济模型预测控制 (EMPC) 可以利用住宅建筑中的热质量来实现区域供热系统中的需求响应 (DR) 目的。然而,缺乏关于居民对空间供暖 EMPC 所固有的室内空气温度波动行为的感知和接受程度的研究。本文报道了一个以丹麦三栋单层住宅的居民为特征的案例研究。这些房屋配备了能够远程启动散热器恒温器和收集各种室内环境数据的技术。模拟散热器 EMPC 的典型行为的四种不同的温度提升干预被执行,而混合方法三角测量设计,采用问卷调查和半结构化访谈的方式收集主观数据。数据显示,居民接受了这种行为,但只有在解释了 EMPC 的好处之后。接受的动机要么是省钱,要么是环境效益,要么是两者兼而有之。因此,结果表明,如果居民要放弃他们当前的偏好和实践以支持 EMPC 概念,那么解释 EMPC 的好处是很重要的。解释应考虑当前偏好、期望和技术先验知识水平的多样性。此外,本文还报告了与在实践中实现 EMPC 的技术方面相关的一系列发现。数据显示,居民接受了这种行为,但只有在解释了 EMPC 的好处之后。接受的动机要么是省钱,要么是环境效益,要么是两者兼而有之。因此,结果表明,如果居民要放弃他们当前的偏好和实践以支持 EMPC 概念,那么解释 EMPC 的好处是很重要的。解释应考虑当前偏好、期望和技术先验知识水平的多样性。此外,本文还报告了与在实践中实现 EMPC 的技术方面相关的一系列发现。数据显示,居民接受了这种行为,但只有在解释了 EMPC 的好处之后。接受的动机要么是省钱,要么是环境效益,要么是两者兼而有之。因此,结果表明,如果居民要放弃他们当前的偏好和实践以支持 EMPC 概念,那么解释 EMPC 的好处是很重要的。解释应考虑当前偏好、期望和技术先验知识水平的多样性。此外,本文还报告了与在实践中实现 EMPC 的技术方面相关的一系列发现。因此,结果表明,如果居民要放弃他们当前的偏好和实践以支持 EMPC 概念,那么解释 EMPC 的好处是很重要的。解释应考虑当前偏好、期望和技术先验知识水平的多样性。此外,本文还报告了与在实践中实现 EMPC 的技术方面相关的一系列发现。因此,结果表明,如果居民要放弃他们当前的偏好和实践以支持 EMPC 概念,那么解释 EMPC 的好处是很重要的。解释应考虑当前偏好、期望和技术先验知识水平的多样性。此外,本文还报告了与在实践中实现 EMPC 的技术方面相关的一系列发现。
