“…Studies show that occupants of green buildings are happier and more satisfied than those of conventional buildings (Symonds et al 2019;Aminuddin et al 2012;Li et al 2018;Meyer 2019). The advantages of green buildings include less waste production, higher interior environmental quality, increased productivity, lighting, acoustic management, thermal comfort, and general occupant well-being.…”

In most countries, buildings consume about 50% of the total energy. High energy consumption is still addressed by stakeholders through traditional technical methods, such as design considerations. However, studies suggest that strategic actions achieve a zero net energy or low energy goal depending on the behaviour of building occupants. The objective of this study is to develop methods for modeling and evaluating occupant behaviour in green office buildings. Specifically, this paper aims to present the research questions and hypotheses for the main investigation and to identify the predictors of occupant behaviour in conventional and green buildings based on a literature review. The research found that the behaviour of building occupants in interacting with or using the building, such as using blinds, and curtains, controlling lighting, opening and closing windows, the way they dress, and the temperature of their drinking water to adjust the indoor environment to their needs or tastes, has a strategic impact on the energy performance and consumption of the building. The study also found that the building envelope, building services, natural ventilation, daylighting, artificial lighting, and thermal comfort are the most important predictors of occupant behaviour in green office buildings. User satisfaction with the building depends on user interaction with the building system and the extent of user adaptation and social value systems. It is found that the ontology of positivism and the epistemology of objectivism are the appropriate metaphysical orientations for the main research. The main research includes qualitative and quantitative data. The results suggest that performance surveys, simulations, experiments, case studies, and questionnaires are appropriate for the main research.

“…Apart from the studies stated in Table 2, other studies related to thermal comfort for naturally ventilated building that have been conducted by previous researchers are more towards residential (Attia & Carlucci, 2015;Han et al, 2007;Kubota et al, 2009;Nur'aini, 2017;Taweekun & Tantiwichien, 2013;Wong et al, 2020), office building (Aminuddin et al, 2012;Damiati et al, 2016), educational facilities such as classroom, kindergarten and hostel (Dahlan et al, 2008;Fabbri, 2013;Kamaruzzaman & Tazilan, 2013). So far there is no thermal comfort study and field investigation have been conducted on correctional facilities especially police lockup in hot and humid climate region.…”

Thermal comfort performance of three vacant naturally ventilated Royal Malaysia Police (RMP) case study lockups (LK1 in Penang, LK2 in Melaka & LK3 in Kuala Lumpur) was measured during monsoon change period from Northeast Monsoon to Southeast Monsoon. According to NGO’s report and previous studies, the lockups condition is very poor and hot which contribute to discomfort among detainees. The objectives of the study are to investigate thermal comfort performance of the lockups based on four environmental parameters (Ta, Tr, Va, & RH) through physical measurement, to predict thermal comfort performance based on operative temperature (To) and neutral operative temperature (Tneutop), and to compare the results with thermal comfort criteria recommended by ASHRAE 55 standard and previous thermal comfort studies in hot and humid climate. The results show that To and Tneutop reading of LK1 is exceeding the maximum range recommended by ASHRAE 55 and previous studies by 2% to 8% (To) and 1% (Tneutop) which categorizing LK1 condition as hot. This is mostly due to high hot airflow brought through an ineffective window opening. The results will be used as reference for improvement towards some aspects such as window opening, building finishes materials, space volume and building orientation in future lockup design.

“…Such benefits can be enhanced by the role played (M18) and activities of knowledgeable motivators (M19), as experienced persons were observed to motivate others in water-related GEB practices (Waidyasekara et al, 2016). Component 2 seems to interpret dwellers' agreement on various "comforts" (M08-M10) offered by green features, which can also allow higher energy savings and reduced CO 2 emission (M7) (Aminuddin et al, 2012).…”

PurposeGreening existing buildings (GEB) considerably improves energy efficiency of old buildings, along with other benefits, but it is not widely practiced. As a part of a wider study, this paper aims to evaluate the perception of building dwellers/owners on the challenges and motivators to GEB in Brunei Darussalam.Design/methodology/approachA structured questionnaire survey collected 109 responses from building owners/dwellers. Cronbach's alpha tested the reliability of the data collected. One-sample t-test examined if sample means are consistent with population means. ANOVA examined if different respondent groups significantly agreed on the importance levels of individual factors. Moreover, factor analysis narrowed down the long list of factors in to a smaller number of components.FindingsA set of 30 challenges and 19 motivators of GEB was identified. “Lack of a GEB infrastructure” was identified as the collective key challenge, leading dwellers to recognize lack of support and knowledge and develop wrong perception on GEB. However, “framework of supports,” as a summative motivator, improves knowledge and awareness on GEB, which allows recognizing other benefits and developing a momentum of practicing GEB. Factor analysis suggested a consolidated approach for challenges through six interrelated components, but for motivators to focus on somewhat four independent areas.Originality/valueHouse/building dweller/owners' decision is the key to undertake GEB. This study, apparently for the first time, contributes to identifying the challenges and motivators that influence their decision-making.
