Abstract

A comprehensive understanding of occupant comfort in mixed-mode (MM) buildings is crucial for the design of MM buildings which are being proposed as a low-energy solution to combat the global warming without compromising comfort. Current comfort standards are mainly for naturally ventilated (NV) or air-conditioned (AC) buildings, and there is a significant gap in standards for MM buildings. With comfort databases playing a major role in the development of thermal comfort models, the recently published ASHRAE Global Thermal Comfort Database II is utilised, in this research, to investigate the thermal sensation and occupant’s behavioural adaptations in MM buildings in temperate oceanic climates and to develop an adaptive thermal comfort model based on the outdoor environmental conditions. The Fanger's PMV model was found to underpredict the actual thermal sensation of the occupants while the occupant adaptivity was found to be lower than that predicted by the adaptive models of Standard 55 and EN15251/EN 16798-1. Furthermore, based on the results of this study and the various impediments faced, recommendations are proposed for future comfort surveys so that more detailed and conclusive studies can be conducted for wider applications using open-source thermal comfort databases. Practical application Good understanding of occupant comfort is necessary to reduce building energy consumption without compromising comfort. This article explores the use of ASHRAE Comfort Database II for determining occupant comfort in MM buildings in temperate oceanic climates and the limitations faced therein. A practical and publicly accessible database developed based on the recommendations from this study will improve thermal comfort models and enable better prediction of occupant comfort while improving energy efficiency substantially.
基于美国采暖、制冷和空调工程师学会舒适度数据库的温带海洋性混合模式建筑热舒适性评价2
综合了解混合模式(MM)建筑的居住者舒适度对于MM建筑的设计至关重要,这是一种低能耗的解决方案,可以在不影响舒适度的情况下对抗全球变暖。目前的舒适性标准主要针对自然通风(NV)或空调(AC)建筑,MM建筑的标准差距较大。由于舒适性数据库在热舒适模型的开发中发挥着重要作用,本研究利用最近出版的ASHRAE全球热舒适数据库II,研究温带海洋性气候下MM建筑的热感觉和居住者的行为适应,并开发基于室外环境条件的适应性热舒适模型。Fanger的PMV模型低估了乘员的实际热感觉,而乘员的适应性低于标准55和EN15251/EN 16798-1的自适应模型。此外,基于本研究的结果和面临的各种障碍,提出了对未来舒适性调查的建议,以便使用开源热舒适数据库进行更详细和结论性的研究,以实现更广泛的应用。要在不影响建筑舒适度的前提下降低建筑能耗,对居住者舒适度有充分的了解是必要的。本文探讨了使用ASHRAE舒适度数据库II来确定温带海洋性气候下MM建筑的居住者舒适度及其面临的局限性。根据本研究的建议开发的实用且可公开访问的数据库将改进热舒适模型,并在大幅提高能源效率的同时更好地预测乘员舒适度。
