{"title":"Evaluating graphical user interfaces for buildings","authors":"Esa Halmetoja, F. Forns-Samso","doi":"10.1108/jcre-08-2019-0037","DOIUrl":"https://doi.org/10.1108/jcre-08-2019-0037","url":null,"abstract":"The purpose of this paper is to evaluate six different graphical user interfaces (GUIs) for facilities operations using human–machine interaction (HMI) theories.,The authors used a combined multi-functional method that includes a review of the theories behind HMI for GUIs as its first approach. Consequently, heuristic evaluations were conducted to identify usability problems in a professional context. Ultimately, thematic interviews were conducted with property managers and service staff to determine special needs for the interaction of humans and the built environment.,The heuristic evaluation revealed that not all the studied applications were complete when the study was done. The significant non-motivational factor was slowness, and a lighter application means the GUI is more comfortable and faster to use. The evaluators recommended not using actions that deviate from regular practice. Proper implementation of the GUI would make it easier and quicker to work on property maintenance and management. The thematic interviews concluded that the GUIs form an excellent solution that enables communication between the occupant, owner and service provider. Indoor conditions monitoring was seen as the most compelling use case for GUIs. Two-dimensional (2D) layouts are more demonstrative and faster than three-dimensional (3D) layouts for monitoring purposes.,The study provides an objective view of the strengths and weaknesses of specific types of GUI. So, it can help to select a suitable GUI for a particular environment. The 3D view is not seen as necessary for monitoring indoor conditions room by room or sending a service request. Many occupants’ services can be implemented without any particular layout. On the other hand, some advanced services were desired for the occupants, such as monitoring occupancy, making space reservations and people tracking. These aspects require a 2D layout at least. The building information model is seen as useful, especially when monitoring complex technical systems.,Earlier investigations have primarily concentrated on investigating human–computer interaction. The authors’ studied human–building interaction instead. The notable difference to previous efforts is that the authors considered the GUI as a medium with which to communicate with the built environment, and looked at its benefits for top-level processes, not for the user interface itself.","PeriodicalId":45969,"journal":{"name":"Journal of Corporate Real Estate","volume":"22 1","pages":"48-70"},"PeriodicalIF":2.3,"publicationDate":"2020-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1108/jcre-08-2019-0037","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48396126","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}

This tool is particularly useful for making strategic decisions in facility planning, portfolio management, investment appraisal, development project evaluations and deciding on usage possibilities in an unbiased, objective manner.,The proposed EDSS uses fuzzy logic and uncertainty theory as two of the most useful tools to deal with uncertainties involved in the problem environment. The system performs an unbiased mathematical analysis on the input data provided by the decision-maker, using a combination of Analytical Hierarchy Process (AHP) and Global Criterion Method; determines a suitable compromise level between the objectives; and delivers a set of locations that complies best with the outlined desires of the management as the final solution. The application of the system is tested on a real case and has delivered satisfactory results.,The proposed EDSS took the defined objectives, the list of alternative locations, and their attributes as the required input for problem-solving, and used a combination of AHP, Possibilistic approach, and global criterion method to solve the problem. The delivered outcome was a set of proper locations with the right attributes to meet all objectives of the organization at a satisfactory level, confirmed by the problem owners.,The application of such a system with such a degree of preciseness and complexity has been very limited in the literature. The system designed in this study is an Industry 4.0 decision making tool. For designing this system several body of knowledge are used. The present study is particularly useful for making strategic decisions in the domains of portfolio management, investment appraisal, project development evaluations and deciding on property usage possibilities. The proposed EDSS takes the information provided by the experts in the field (through qualitative and quantitative data collecting) as the inputs and operates as an objective decision-making tool using several bodies of knowledge considering the trends and developments in the world of FREM. The strong scientific method used in the core of the proposed EDSS guarantees a highly accurate result.","PeriodicalId":45969,"journal":{"name":"Journal of Corporate Real Estate","volume":"22 1","pages":"21-47"},"PeriodicalIF":2.3,"publicationDate":"2019-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1108/jcre-03-2019-0019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43869331","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}

Coworking spaces may impose various approaches that not only attract potential workspace users and form initial ties between them but also produce a certain ambience that leads to collaborative action between users. The factors of spatial design need to be adapted, and engagement strategies need to be constructed to maximise the preferential output.

New working practices (NWPs) are viewed as a reform tool to manage expensive real estate around the world. However, it is unclear whether NWPs influence office space usage in business organizations in Hong Kong. This study, therefore, aims to evaluate if the average space reduction in office firms is caused by the NWPs in the finance, insurance, real estate and business (FIREB) firms.\u0000\u0000\u0000Design/methodology/approach\u0000A total of 20 NWPs were initially derived from the extant literature. A questionnaire survey was conducted with listed FIREB firms in Hong Kong to assess the impact of the identified NWPs on space usage. The data collected from the questionnaire survey were analysed using descriptive, explorative factor analysis (EFA) and partial least squares-structural equation modelling (PLS-SEM) to evaluate the effects of NWPs on average space usage.\u0000\u0000\u0000Findings\u0000Results revealed that four major NWP factors influence average space usage. Three of these factors, namely, “flexible arrangement”, “multitasking knowledge workers” and “teamwork and communication”, influence space usage positively. Even though the effect of the fourth factor “training and networking” was significant, it does not reflect a positive influence on space usage. Business organizations can focus more on the implementation of NWPs to cushion the effects of the high cost of occupancy.\u0000\u0000\u0000Originality/value\u0000The research provides new knowledge to the limited literature on the effect of NWPs in FIREB firms and enriches the growing body of international literature on how today’s competitive global business organizations should revisit their workplace strategies to accommodate the rising agile workforce and NWPs.
