    Enhancing the Energy Performance of Historic Buildings Using Heritage Building Information Modelling: A Case Study
    (MDPI (Basel, Switzerland), 2025-07-02) Kakouei M; Sutrisna M; Rasheed E; Feng Z; Caggiano A; Kamari A
    Heritage building conservation plays a special role in addressing modern sustainability challenges by preserving the cultural identity, retrofitting, restoring, and renovating these structures to improve energy performance, which is crucial for revitalisation. This research aims to use Heritage Building Information Modelling (HBIM) to increase energy efficiency and environmental sustainability in historic buildings. Retrofitting heritage buildings presents unique challenges and opportunities to simultaneously reduce energy consumption and carbon emissions while maintaining historical integrity. Traditional approaches are often insufficient to meet heritage structures’ energy needs. Modern technologies such as information building modelling and energy simulations can offer solutions. HBIM is a vigorous digital framework that facilitates interdisciplinary collaboration and offers detailed insights into building restoration and energy modelling. HBIM supports the integration of thermal and energy efficiency measures while maintaining the authenticity of heritage architecture by creating a comprehensive database. Using a case study heritage building, this research demonstrates how retrofitting the different aspects of heritage buildings can improve energy performance. Evaluating the preservation of heritage buildings’ cultural and architectural values and the effectiveness of using HBIM to model energy performance offers a viable framework for sustainable retrofitting of heritage buildings.

    Systematic Review on the Barriers and Challenges of Organisations in Delivering New Net Zero Emissions Buildings
    (2024-06-16) Mahmoodi M; Rasheed E; Le T
    Achieving the net zero emissions target that was set in the Paris Agreement to mitigate the risks of climate change seems increasingly difficult as countries and sectors of the economy are falling behind the expected trajectory. The building and construction industry, as one of the main contributors to global emissions, has an essential role to play toward this aim. Net zero emissions target has been introduced to this sector as well; however, achieving it is a very challenging and complex task. Many studies have been undertaken on implementing different measures and strategies to reduce the industry’s carbon footprint. These studies identified many challenges and barriers in transforming the industry. This paper aims to provide a systematic review of challenges that organisations face in delivering new net zero emissions buildings. The relevant journal articles published since the Paris Agreement were identified and analysed using mixed-method data analysis, including quantitative (science mapping) and qualitative (thematic) analysis. The result showed increased attention to the subject over this period, with China, the UK, and Australia being the top contexts for research. The most discussed groups of barriers were “economic”, “knowledge”, and “technical”, respectively, followed by “organisational”, “market”, “technological”, and “legal” barriers.

    Proactive post-occupancy evaluation
    (Build Magazine, 2021-08-02) Rasheed E; Rotimi J; Vilasini N; Weerasinghe A
    A digital post-occupancy evaluation system for checking the operational performance of commercial buildings will be a useful tool as New Zealand faces the need to meet stringent carbon targets.

    Do Green Buildings Have Superior Performance over Non-Certified Buildings? Occupants’ Perceptions of Strengths and Weaknesses in Office Buildings
    (MDPI AG, 25/08/2022) Khoshbakht M; Rasheed E; Baird G
    The main objectives of green buildings are to improve their design and operation. Many studies have investigated whether green buildings lead to higher occupant satisfaction, yet with contradictory conclusions. The paper builds on the results of post-occupancy evaluation surveys of 68 buildings using the BUS Methodology. Satisfaction scores expressed by occupants with the qualities of their indoor environment were compared between the green and non-certified buildings. This research investigates whether green buildings have superior performance to non-certified buildings from the occupants’ perspectives. It was found that generally occupants were more satisfied in green buildings than in non-certified buildings. However, the differences were not significant for any of the environmental and operational parameters including thermal comfort, lighting, noise, and air quality. In the case of operational parameters such as design, needs, image of the building, and cleaning, the differences between the two building groups were notable. Air quality, design and work requirement had the strongest influence on perceived comfort in both green and non-certified buildings. Noise had the strongest influence on perceived productivity for both building groups. Although overall green buildings performed better than the non-certified buildings, the differences between the two were negligible particularly for environmental parameters. Most of the green buildings were not performing entirely as their designers may have intended and had weaknesses that needed to be addressed.

    Does the Number of Occupants in an Office Influence Individual Perceptions of Comfort and Productivity?-New Evidence from 5000 Office Workers
    (MDPI (Basel, Switzerland), 25/03/2019) Rasheed E; Khoshbakht M; Baird G
    Purpose—The purpose of this article is to present evidence of occupants’ perception of their work environment in five different office types (Solo, Duo, 2–4, 5–8 and 8Plus offices). The study examined the influence of the number of office occupants on individual perception of indoor environment quality (IEQ) in office environments. Design/methodology/approach—A dataset of 5000 respondents in 67 commercial and institutional office buildings was analysed using IBM SPSS v23. The dataset contained user response on the BUS Methodology questionnaire that is designed to retrieve occupants’ perception of their work environments. Analysis of Variance (ANOVA) and multiple regression analysis were conducted to calculate the impact of the office environment on occupants’ perception of comfort and productivity. Findings - This study showed that occupants in Solo and Duo offices perceived higher satisfaction with their environment (except for temperature in summer), better health and productivity; and more control over the office environment than those in 5–8 and 8Plus offices. Occupants in 8Plus offices were most satisfied with the temperature in summer. It was also noted that the IEQ factors that predicted comfort were observed to not predict productivity. Noise was the only IEQ factor that had predictive power for both comfort and productivity in all the office spaces. Originality/value—This article provides intriguing findings on occupants’ perception of various types of office environment that contributes significantly to the debate on open-plan versus cellular office environments.
