ABSTRACT This is a methodological, cross-sectional descriptive study designed with the purpose of developing a valid and reliable measurement instrument allowing determination of the Comfort of PPE used by healthcare workers. The draft scale which was reduced to 20 items after content validity analysis was prepared as a 5-point Likert-type scale and applied to 502 volunteering healthcare workers employed at state, university and private hospitals in the province of Istanbul in Turkey. The scale was tested for validity and reliability. Internal consistency and test-retest reliability analyses were used to assess reliability, exploratory factor analysis was conducted with the SPSS software, and confirmatory factor analysis was conducted with the Lisrel software. As a result of the analyses, a 20-item scale consisting of 3 dimensions and explaining 63.14% of the total variance was developed. The Cronbach’s α value for the entire scale was determined as 0.93. For test-retest reliability, the scale was applied again on the same group with a two-week interval, and the correlation coefficient was found significant. The three-factor construct was confirmed with the confirmatory factor analysis. The PPE Comfort Scale may be used in a group of healthcare workers as a valid and reliable instrument.

ABSTRACT Focusing on the housing issue which segregates city dwellers and marginalises the migrants, this paper proposes an architectural transformation of a dominant type in Chinese cities, in search of a sustainable regeneration strategy which encourages social integration. This paper is concerned with two main issues: how to transform a dominant type of high-rise residential living – i.e. tower-podium residential – in China to promote a sustainable city, architecture and community; and how to integrate migrant-working class with the middle-income class to form a hybrid cohabitation place. The paper uses a design project to put forward a hypothesis, focusing on modifying the spaces of the podium in a tower-podium residential building in Xiaowen Street, Ningbo to provide a cohabitation living space for both migrant-working class and middle-income class group. The design creates spaces for living, co-working and community interaction, etc. to cultivate hybrid programme and spaces aided by informal spatial design strategies. Besides providing a case study of typological transformation with a tower-podium housing type of Ningbo, the study also contributes to the literature of informal cities and design strategies in seeing architectural design as an active agent for social changes.

ABSTRACT Since the outbreak of COVID-19, wearing a mask, voluntary or obligatory, has led to diverse and numerous designs. Guidelines for minimum requirements include tests for visual inspection, strength, filtration, and breathing resistance, but not for the fit of a mask. The fit of a mask was assessed by testing the outward leakage of exhaled breath based on the visualization of coloured mist exhaled by a manikin head. Fourteen masks were selected based on differences in design, such as type of material, shape (cheek wings vs. none), filter type, and the number of layers. Leakage expressed in mean mist percentages (visualized with a camera), patterns of coloured mist left inside the masks, as well as visual fit of the masks on the manikin head, showed that a loose fit mask results in more leakage. Also, combining quantitative with qualitative assessment proved to be complementary. Future tests should be conducted on a range of users, covering the best fit over time as well breathability, use, and comfort. The use of face masks, whatever their characteristics, seem an adequate strategy to reduce the dispersion of potential ‘infected’ aerosols into the space from people, as opposed to not wearing one.

ABSTRACT In the last two decades, automation systems have shown advanced developments and are widely adopted for various purposes in many fields. However, automation in buildings has not gained popularity and has a low acceptance level amongst the occupants. Decreased perceived control, ever-changing dynamic human needs, and standardized, one-size-fits-all approach in current automation systems lead to disharmony in human-machine coexistence. Although well-established continuous interaction between building control systems and occupants is acknowledged as one of the core elements of intelligent buildings, defined borderlines of the prevailing automation modalities fail to satisfy this primary feature. This research proposes a conceptual mixed-initiative building control framework enhancing collaboration and communication between building occupants and the automation. Through benefiting from both the control capacity of computer-powered methods and flexibility granted by incorporating occupants in the loop, demonstrated framework components may enact concurrent assessment of occupant comfort and energy efficiency while making automated applications more favorable for building inhabitants.

ABSTRACT Industrial sector consumes a substantial portion of electrical energy. Building owners persistently believe that combining on-site renewable energy systems to buildings is not cost-effective in Sri Lanka. Therefore, this research aimed to evaluate the use of on-site renewable energy sources for industrial buildings in Sri Lanka. This research carried out 10 expert interviews and 6 case studies. Experts determined that solar and biomass as viable on-site energy generating sources in Sri Lanka. Life-cycle cost was calculated for six case studies representing three case studies for each viable option followed by a sensitivity analysis. Based on the research findings, biomass can effectively manage waste while eliminating the risk of the emission of harmful biomethane. Based on the calculations, the payback period for a solar system varies between 4 and 6 years and biomass system varies between 6 and 7 years. This research explored the potential of generating on-site renewable energy for industrial building. Although the ‘on-site’ energy generation is not widely discussed in industrial buildings, this research study strengthened the possibility of adopting solar and biomass as on-site renewable energy generation sources.

ABSTRACT A Business Model (BM) is fundamental to the success of any business because it creates and captures value. BMs are widely known in several disciplines where it has been given idiosyncratic definitions to suit the respective disciplines. Because definitions can bring clarity to the terms they define, this study attempted to define the BM relevant to a construction business. The methodology followed included a structured literature review and content analysis. From 38 BM definitions, 10 themes were located using the keywords abstracted from each definition. From among the ten themes, eight construction business-specific ‘fundamental themes’ were selected. The ‘wordings’ extracted from the definitions associated with the eight themes were used to develop a BM definition for the construction business. The proposed definition will facilitate a better understanding of construction businesses. It, therefore, will promote the application of the BM concept in the construction industry.

ABSTRACT For sedentary activities, the PMV equation, derived by Fanger, is mainly based on the research of Nevins et al. (720 test subjects). Nevins' experiments were later on repeated by Fanger, but with 128 college-age Danish subjects and 128 elderly Danish subjects, instead of American subjects. Rohles did the research from Nevins et al. again, but over a more extensive temperature range and more, namely 1600, test subjects. Rohles' research results have been partly included in the derivation of the PPD equation, but not in the derivation for the PMV equation. Rohles' experimental results are published at a later time than the publication of the thesis of Fanger. The question arises: ‘If Rohles' experimental results were included in the derivation of the PMV equation, instead of Nevins' experimental results, to what extent does that change the PMV equation and the application area of the PMV equation, with regard of validity, for sedentary activities?'. In the same way, as Fanger described in his thesis, and using the results of Rohles’ experiment, this study is limited to the derivation of a PMV equation with a wider PMV range than −2 to 2, for sedentary activities.

ABSTRACT Architects are increasingly integrating principles of biophilic design to foster experiences of nature in regularly occupied buildings such as schools. Although researchers often objectively measure building variables to document the presence of nature, few tools currently help architects assess subjective biophilic experiences during building walkthroughs in the preliminary design stages of renovation projects. This paper presents the results of a pilot study designed to assist the development of an architectural diagnostic tool that represents designers’ experiences of natural elements such as sunlight, wind and snow. The Biophilic Experience Representation Tool (BERT) was used during site visits in two Canadian primary schools in winter. These post-occupancy evaluations with BERT highlight its potential to discuss subjective dimensions of biophilic architecture. It further reveals the importance of seasonality when assessing and designing biophilic buildings in cold climates.

The Biophilic Experience Representation Tool (BERT) was used during site visits in two Canadian primary schools in winter. These post-occupancy evaluations with BERT highlight its potential to discuss subjective dimensions of biophilic architecture. It further reveals the importance of seasonality when assessing and designing biophilic buildings in cold climates.","PeriodicalId":45828,"journal":{"name":"Intelligent Buildings International","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2021-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17508975.2021.1925209","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43329651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT Architecture's reach into neuroscience has demonstrated the value of biometric data, particularly neurophysiological data captured through the use of portable electroencephalography (EEG) technology, in understanding users’ physiologic responses to spaces. While methods employing portable EEG technology are increasingly being used to study a variety of everyday settings, office environments have not yet been the subject of such studies. To address this gap, we used portable EEG sensors and heart rate monitors to conduct a pilot-scale, quasi-experiment of office occupants in their space and then again when that group relocated to new space several months later. Our findings revealed that users experienced the new office, particularly its café space, in a more relaxed way compared to the old office, suggesting that neurophysiologic data can be used in describing the effects of design features and affordances. When conducted before and after an office space redesign, biometric studies of office users broaden the methodological diversity of post-occupancy evaluations. We reflect on the significance of our findings, given our pilot approach and limited sample size, with respect to biometric data's role in the design of mixed methods post-occupancy evaluations. We also reflect on directions for future research of office environments.
