Thermal environmental adjustment is one of the most important behaviours. In our daily life, we use some behavioural adjustments for thermal comfort such as fan use. The occupant-behavioural stochastic models were proposed by some previous studies. However, the relative proportion of each behaviour has not yet been fully understood. It is important to make it possible to estimate the proportion of each behaviour relatively because how one or more behaviours is determined in relation to each others. In our previous study, the stochastic models of window open/closed, cooling and heating use were integrated in one model and thereby one holistic model was made. The integrated fan use model is useful for understanding the occupant behaviour. The objective of this study is to clarify the fan use in relation to the window open and cooling use. For this purpose, the occupant behaviour surveys were conducted in 120 dwellings during a four-year period in Kanto region of Japan. From this survey, we have collected 36,114 responses. The major findings are: 1) the proportion of fan use was highest in summer; 2) the stochastic model of fan use was explained by outdoor air temperature, and the combined stochastic model of “fan use” and “window opening or cooling use” were developed; and 3) the proportion of the “combined fan use” was higher than that of “fan single use”. The results indicated that the residents in Japanese dwellings often use fans with window opening or cooling use, and thus it is important to clarify the fan use behaviour as “combined pattern”. The knowledge of this research can be used in building thermal simulation reflecting realistic occupant behaviour.

开发包括日式住宅中的风扇在内的乘员-行为随机综合模型

热环境调节是最重要的行为之一。在日常生活中,我们会通过一些行为调整来提高热舒适度,例如使用风扇。先前的一些研究提出了乘员行为随机模型。但是,每种行为的相对比例尚未完全了解。重要的是使相对估计每种行为的比例成为可能,因为一个或多个行为是如何相对于彼此确定的。在我们以前的研究中,将窗户开/关,制冷和供热使用的随机模型集成到一个模型中,从而制作了一个整体模型。集成的风扇使用模型有助于理解乘员的行为。这项研究的目的是弄清与开窗和冷却使用有关的风扇使用情况。为此,在日本关东地区的四年中,在120户住宅中进行了居民行为调查。从这次调查中,我们收集了36114份回复。主要发现是:1)夏季风机使用比例最高。2)用室外空气温度解释了风机使用的随机模型,并建立了“风机使用”和“开窗或制冷使用”的组合随机模型;(3)“组合风机使用”比例高于“风机单独使用”比例。结果表明,日本民居居民经常使用带有开窗或制冷用途的风扇,因此,将风扇的使用行为明确为“组合模式”非常重要。该研究的知识可用于建筑热模拟,以反映实际的乘员行为。在四年的时间里,在日本关东地区对120所住宅进行了居民行为调查。从这次调查中,我们收集了36114份回复。主要发现是:1)夏季风机使用比例最高。2)用室外空气温度解释了风机使用的随机模型,并建立了“风机使用”和“开窗或制冷使用”的组合随机模型;(3)“组合风机使用”比例高于“风机单独使用”比例。结果表明,日本民居居民经常使用具有开窗或制冷用途的风扇,因此,将风扇的使用行为明确为“组合模式”非常重要。这项研究的知识可用于建筑热模拟,以反映实际的乘员行为。在四年的时间里,在日本关东地区对120所住宅进行了居民行为调查。从这次调查中,我们收集了36114份回复。主要发现是:1)夏季风机使用比例最高。2)用室外空气温度解释了风机使用的随机模型,并建立了“风机使用”和“开窗或制冷使用”的组合随机模型;(3)“组合风机使用”比例高于“风机单独使用”比例。结果表明,日本民居居民经常使用带有开窗或制冷用途的风扇,因此,将风扇的使用行为明确为“组合模式”非常重要。该研究的知识可用于建筑热模拟,以反映实际的乘员行为。
