ABSTRACT This research assesses whether the perceived indoor air quality (IAQ) can be improved with additional sensors in older buildings. The research does not investigate IAQ in its broadest sense, but focus on phenomena perceived by the human senses, such as thermal comfort. The effects of the maintenance of technical systems on perceived IAQ are also studied. In the study, 2506 sensors were installed in 29 public buildings in nine cities in Finland. The change in studied indicators was measured over four years and compared to 65 buildings in the comparison group. The study provides an objective view of the usefulness of BAS-connected and cloud-based sensors. The study also shows that a building owner considering introducing cloud technology to improve perceived IAQ should also be prepared to reform property maintenance processes. The study showed that additional sensors connected to the BAS improve thermal stability. No such improvement was observed in sensors connected to cloud services.
本研究评估了在旧建筑中增加传感器是否可以改善室内空气质量(IAQ)。这项研究没有从最广泛的意义上调查室内空气质量,而是关注人类感官感知到的现象,比如热舒适。还研究了技术系统维护对感知室内空气质量的影响。在这项研究中,2506个传感器安装在芬兰9个城市的29座公共建筑中。研究指标的变化是在四年的时间里测量的,并与对照组的65座建筑进行了比较。该研究为bas连接和基于云的传感器的有用性提供了客观的观点。该研究还表明,考虑引入云技术以改善感知的室内空气质量的建筑物业主也应该准备改革物业维护流程。研究表明,与BAS连接的附加传感器提高了热稳定性。在连接到云服务的传感器中没有观察到这种改善。

ABSTRACT The New Zealand Ministry of Education has a single electronic monitoring device (sensor) that simultaneously measures five environmental elements (light, temperature, relative humidity, noise, and carbon dioxide levels) in some schools. The aim is to develop an indoor environment monitoring protocol to inform proactive assets management of school buildings. This study used observations and actual measurements of these environmental variables in three typical classrooms in three schools, to assess whether the use of a one-point sensor in one location could predict the thermal condition across a classroom. The results revealed that a single sensor located at a height of 1.5 m on an unglazed vertical wall with a low thermal mass, and away from direct sunlight, heating and cooling systems, and drafts from open windows can be used to identify good and poor thermal conditions in classrooms. A one-point sensor provides a general indication of the thermal performance of a room, but not the thermal variations across the room. This study provides a systematic method for using a single sensor to monitor thermal performance in a large school property portfolio for early discrimination from hundreds or more classrooms to direct thermal intervention programmes for large groups of school buildings.
新西兰教育部有一个单一的电子监控设备(传感器),可以同时测量一些学校的五种环境要素(光线、温度、相对湿度、噪音和二氧化碳水平)。目的是制定一个室内环境监测协议,为学校建筑的主动资产管理提供信息。本研究在三所学校的三个典型教室中对这些环境变量进行了观察和实际测量,以评估在一个位置使用单点传感器是否可以预测整个教室的热状况。研究结果表明,单个传感器位于1.5米高的无玻璃垂直墙上,热质量低,远离阳光直射,加热和冷却系统,以及打开窗户的通风,可以用来识别教室的良好和不良的热条件。单点传感器提供一个房间的热性能的一般指示,但不是整个房间的热变化。本研究提供了一种系统的方法,使用单个传感器监测大型学校物业组合中的热性能,以便从数百个或更多教室中进行早期识别,从而为大型学校建筑群体提供直接的热干预方案。

ABSTRACT Offsite prefabrication (OP) is an important approach in overcoming some inefficiencies in the U.K. construction sector. Whilst growth in OP can be demonstrated, its uptake is limited in relation to the expected benefit of its application. Perception, in part due to historical application, has been highlighted as a significant contributing factor in its limited uptake. However, despite recognition that the uncertainties associated with perception on OP are important to technological innovation adoption, these uncertainties were not explored in the previous studies. We adopt fuzzy-set theory, in combination with a survey from 76 organisations in the U.K., to explore these uncertainties in perception for a broad range of OP applications. Through fuzzy-set analysis, the study presents insight into some of the uncertainties related to the perception of OP through three themes: Uptake, Impression, and Strategy. This study proposes that the uncertainty in the perception of OP value, within specific and across all applications, needs to be explicitly considered to understand how perception is informing uptake. This research also suggests that negative perception is one of the key constraints to uptake and it is in fact the overall culture of the U.K. construction sector that is limiting the uptake of OP.
摘要:场外预制(OP)是克服英国建筑行业效率低下的一种重要方法。虽然OP的增长是可以证明的,但与应用的预期效益相比,其吸收是有限的。部分由于历史应用,感知被强调为其吸收有限的一个重要因素。然而,尽管人们认识到与OP感知相关的不确定性对技术创新的采用很重要,但在以前的研究中没有探讨这些不确定性。我们采用模糊集理论,结合对英国76个组织的调查,探讨了在广泛的OP应用中感知的这些不确定性。通过模糊集分析,该研究通过三个主题:接受、印象和策略,深入了解了与OP感知相关的一些不确定性。这项研究提出,在特定和所有应用中,需要明确考虑OP值感知的不确定性,以了解感知是如何影响吸收的。这项研究还表明,负面认知是吸收的关键制约因素之一,事实上,正是英国建筑业的整体文化限制了OP的吸收。

ABSTRACT This research proposes an investigation on the problem of detecting and predicting occupancy by using solely readily available electricity consumption data, obtained from smart metres. The following research questions are defined: (1) Is it possible to predict occupancy by using solely electricity consumption data?; (2) Is it possible to use a single classification model to monitor occupancy in multiple households? The findings show that an occupancy detection accuracy of up to 92% can be achieved by using solely electricity consumption data. The problem of generalizing the classification model, i.e. using a single classification model to monitor occupancy in multiple households, is also addressed. It is found that an occupancy detection accuracy of up to 83% is achievable in this case. Regarding occupancy prediction, occupancy in multiple households with an accuracy of up to 75% is obtained, by using solely electricity consumption data. For both occupancy monitoring and prediction, it is found that households with a low level of occupancy can benefit more from these systems.
摘要:本研究提出了一个调查的问题,检测和预测占用仅使用现成的电力消耗数据,从智能电表获得。定义了以下研究问题:(1)是否可以仅用用电量数据来预测入住率?(2)是否可以使用单一分类模型来监测多个住户的入住率?研究结果表明,仅使用用电量数据就可以实现高达92%的占用率检测准确率。本文还讨论了推广分类模型的问题,即使用单一分类模型来监测多个家庭的占用情况。研究发现,在这种情况下,占用率检测准确率可达83%。在入住率预测方面,仅使用用电量数据就可以获得多户入住率,准确率高达75%。对于入住率监测和预测,发现入住率低的家庭从这些系统中获益更多。

ABSTRACT Next to personal, psychosocial and physiological aspects, environmental aspects of homes may affect the health and comfort of their occupants. This study aimed to investigate the multifactorial character of both rhinitis and headaches among five groups of students from universities in five different cities: Taichung (Taiwan), Concepcion (Chile), Paramaribo (Suriname), Beijing (China) and Delft (The Netherlands). Among the students studied, 18% declared having suffered from rhinitis in the last 12 months, and 30% from headaches in the last 3 months. Self-reported characteristics of 682 students and their homes were linked to self-reported rhinitis and headaches. Logistic regression modelling was applied to explore relations between building-related factors and rhinitis, and between building-related factors and headaches. After full adjustment, the regression model for both rhinitis and headaches confirmed their multifactorial character. While personal-related factors family rhinitis and age were associated with rhinitis, negative events and PANAS negative were with headaches. Biological pollutants (caused by pets) were associated both with rhinitis and headaches; chemical pollutants, caused by open bookshelves and lack of sweeping floors, were associated with rhinitis. The study concludes that the identified risk factors seemed independent of season or climate region.
摘要除了个人、社会心理和生理方面,家庭的环境方面也可能影响居住者的健康和舒适。本研究旨在调查台湾台中市、智利康塞普西翁市、苏里南帕拉马里博市、中国北京市和荷兰代尔夫特市五组大学学生鼻炎和头痛的多因素特征。在所研究的学生中,18%的学生声称在过去12个月内患有鼻炎,30%的学生在过去3个月内头痛。682名学生及其家庭的自我报告特征与自我报告的鼻炎和头痛有关。应用Logistic回归模型探讨了建筑相关因素与鼻炎以及建筑相关因素和头痛之间的关系。在完全调整后,鼻炎和头痛的回归模型证实了它们的多因素特征。虽然个人相关因素家族性鼻炎和年龄与鼻炎有关,但阴性事件和PANAS阴性与头痛有关。生物污染物(由宠物引起)与鼻炎和头痛有关;开放的书架和没有扫地引起的化学污染物与鼻炎有关。研究得出结论,确定的风险因素似乎与季节或气候区域无关。

ABSTRACT The underlying factors of housing research emanate from the fact that people's lives and well-being rely on the quality of the house and the surroundings where it is situated. Housing satisfaction goes beyond brick and mortar and aesthetics. It examines housing attributes that are not already visible to the eyes that could influence the occupants’ satisfaction with such buildings. This study investigated user's satisfaction with private housing estates using the Analytical Hierarchy Process (AHP). The research is imperative because most studies in Nigeria focused mainly on government-owned or social housing satisfaction. While private housing estates have received little attention over the years. 280 questionnaires were randomly distributed to the building occupants within the estates under consideration based on their level of availability during the 13 weeks surveyed periods. From the survey, the top-ranked factors that influence user satisfaction were utility adequacy, infrastructural, provision of facilities, and maintenance factors with the priority weight of 0.425, 0.235, and 0.203 accordingly. Therefore, real estate practitioners and housing developers must take these housing attributes into proper consideration to promoting a better quality of living, enhancing building performance that could increase the total return on investment, and meet the overall user satisfaction.
摘要住房研究的基本因素源于这样一个事实,即人们的生活和幸福取决于房屋及其所在环境的质量。住房满意度超越了实体和美学。它研究了眼睛还看不到的住房属性,这些属性可能会影响居住者对此类建筑的满意度。本研究采用层次分析法(AHP)对私人住宅小区的使用者满意度进行调查。这项研究势在必行,因为尼日利亚的大多数研究主要集中在政府所有或社会住房满意度上。虽然私人住宅近年来很少受到关注。在13周的调查期内,根据住户的可用性水平,向考虑中的屋苑内的住户随机发放了280份问卷。根据调查,影响用户满意度的首要因素是公用事业充足性、基础设施、设施提供和维护因素,优先级权重分别为0.425、0.235和0.203。因此,房地产从业者和住房开发商必须适当考虑这些住房属性,以提高生活质量,提高建筑性能,从而提高总投资回报率,并满足整体用户满意度。

A data-driven approach for window opening predictions in non-air-conditioned buildings 非空调建筑开窗预测的数据驱动方法

ABSTRACT In non-air-conditioned buildings, opening or closing of windows is one of the most common behaviours that occupants tend to carry out to restore their thermal comfort. As an alternative approach to studying the occupant behaviour, particularly when it is difficult to run extensive field studies or due to limits like privacy concerns, this work explores a data-driven method to predict the window openings based on thermal comfort evaluation. The Gradient Boosting Decision Trees (GBDT) algorithm is applied to investigate the importance of selected features, including weather and main building characteristics, to the indoor thermal comfort in non-air-conditioned buildings across whole China. The training set comprises the building simulation results of 95 main cities covering all the five climate regions in China and has 828,360 groups of data in total. The predictor achieves a high accuracy of approximately 95%, and therefore enables the users to estimate the likelihood of window opening based on outdoor weather conditions and local building characteristics. As an original contribution, the study shows that conditioned upon the availability of adequate simulation data, a machine learning predictor trained solely on simulation data can accurately predict realistic window opening behaviours, without relying on any indoor measurement.
摘要在非空调建筑中,打开或关闭窗户是居住者为恢复热舒适性而采取的最常见的行为之一。作为研究居住者行为的另一种方法,特别是当很难进行广泛的实地研究或由于隐私等限制时,这项工作探索了一种基于热舒适性评估的数据驱动方法来预测车窗开口。应用梯度提升决策树(GBDT)算法研究了包括天气和主要建筑特征在内的选定特征对中国非空调建筑室内热舒适性的重要性。该训练集包括覆盖中国所有五个气候区域的95个主要城市的建筑模拟结果,共有828360组数据。该预测器实现了大约95%的高精度,因此使用户能够基于室外天气条件和当地建筑特征来估计开窗的可能性。作为最初的贡献,该研究表明,在有足够模拟数据的情况下,仅根据模拟数据训练的机器学习预测器可以准确预测真实的开窗行为,而不依赖于任何室内测量。

ABSTRACT There are different thermal perception models linked to a mathematical thermophysiological human model, with which the thermal sensation under stationary and/or dynamic conditions can be evaluated. Each of these perception and thermophysiological models have their own field of application. Stolwijk developed a thermophysiological human model without an associated thermal perception model, which today is still the basis for other mathematical thermophysiological models. Fiala developed the FPC model, also based on the Stolwijk model, and is one of the latest developments in the field of thermophysiological human models. In the FPC model, an equation is included with which the thermal sensation under stationary and dynamic conditions can be assessed; the so-called Dynamic Thermal Sensation (DTS). The DTS equation is, however, specifically developed for use in combination with the FPC model. In contrast to the Stolwijk model, the source code of the computer programs of the later developed thermophysiological human models is not freely available, which limits the use and applicability of the models in practice. It is precise because of the availability of the source code that the Stolwijk model is still used in industry and the research world. The question, therefore, arises: ‘To what extent can a human transient thermal sensation equation be derived, combined with the Stolwijk model, in a similar way to that used for the DTS equation in the FPC model?’.
摘要:有不同的热感知模型与数学热生理人体模型相关联,通过该模型可以评估静止和/或动态条件下的热感觉。这些感知和热生理模型中的每一个都有自己的应用领域。Stolwijk开发了一个没有相关热感知模型的热生理人体模型,该模型至今仍是其他数学热生理模型的基础。Fiala在Stolwijk模型的基础上开发了FPC模型,是人体热生理模型领域的最新发展之一。在FPC模型中,包括一个方程,利用该方程可以评估静止和动态条件下的热感;即所谓的动态热感觉(DTS)。然而,DTS方程是专门为与FPC模型结合使用而开发的。与Stolwijk模型相比,后来开发的热生理人体模型的计算机程序的源代码不是免费提供的,这限制了模型在实践中的使用和适用性。正是由于源代码的可用性,Stolwijk模型仍在工业界和研究界使用。因此,问题来了:“以与FPC模型中DTS方程类似的方式,结合Stolwijk模型,可以在多大程度上推导出人类瞬态热感方程?”。
