    Benchmarking green technologies: a survey of non-domestic buildings in Sri Lanka
    (Science Exploration Press, 2024) Sachchithananthan M; Ramachandra T; Thayananth M; Rotimi JOB
    The escalating demand for energy and resources in the construction industry, together with poor energy performance of existing buildings, pose challenges for sustainability. Despite the incorporation of advanced technologies in modern construction to reduce energy consumption, a significant number of buildings are yet to adopt sustainable practices, owing to lack of awareness about potential technologies, and the considerations for selection. To this end, the current study aims to survey commercial buildings to explore the technologies implemented together with the basis that influenced the implementation. A detailed survey including semi-structured interviews with professionals engaged in the selected non-domestic buildings were conducted. The selected buildings comprise three (3) certified retrofit, eight (8) certified new and seven (7) non-certified green. The findings show that the buildings have incorporated 54 different technologies under the main sustainability criteria of water efficiency, lighting, heating, ventilation, and air conditioning (HVAC) systems, indoor environmental quality, and sustainable site. Advanced technologies, such as free cooling appliances, on-site wastewater treatments, and water-efficient climate-tolerant plantings, were predominantly found in green-certified buildings, while non-certified buildings tend to adopt more universally applicable and accessible technologies, like LED lighting, compact fluorescent lamps, and low-flow plumbing fixtures. The paper presents a detailed analysis on use of technologies with different building function, green rating levels, and challenges faced. Hence, the study findings would facilitate technology adaptation for a given context by providing insights into the availability and adaptability of green retrofit technologies in the Sri Lankan context for non-domestic buildings.

    Toward Standardised Construction Pipeline Data: Conceptual Minimum Dataset Framework
    (MDPI (Basel, Switzerland), 2025-08-07) Elkhidir E; Rotimi JOB; Patel T; Moshood TD; Wilkinson S
    The construction industry is a cornerstone of New Zealand (NZ)’s economic growth, yet strategic infrastructure planning is constrained by fragmented and inconsistent pipeline data. Despite the increasing availability of construction pipeline datasets in NZ, their limited clarity, interoperability, and standardisation impede effective forecasting, policy development, and investment alignment. These challenges are compounded by disparate data structures, inconsistent reporting formats, and semantic discrepancies across sources, undermining cross-agency coordination and long-term infrastructure governance. To address this issue, the study begins by assessing the quality of four prominent pipeline datasets using Wang and Strong’s multidimensional data quality framework. This evaluation provides a necessary foundation for identifying the structural and semantic barriers that limit data integration and informed decision-making. The analysis examines four dimensions of data quality: accessibility, intrinsic quality, contextual relevance, and representational clarity. The findings reveal considerable inconsistencies in data fields, classification systems, and levels of detail across the datasets. Building on these insights, this study also develops a conceptual minimum dataset (MDS) framework comprising three core thematic categories: project identification, project characteristics, and project budget and timing. The proposed conceptual MDS includes unified data definitions, standardised reporting formats, and semantic alignment to enhance cross-platform usability and data confidence. This framework applies to the New Zealand context and is designed for replication in other jurisdictions, supporting the global push toward open, high-quality infrastructure data. The study contributes to the construction informatics and infrastructure planning by offering a practical solution to a critical data governance issue and introducing a transferable methodology for developing minimum data standards in the built environment to enable more informed, coordinated, and evidence-based decision-making.

    Combating Greenwashing of Construction Products in New Zealand and Australia: A Critical Analysis of Environmental Product Declarations
    (MDPI AG, 2024-11-06) Moshood TD; Rotimi JOB; Rotimi FE
    The construction industry’s increasing environmental impact has led to the widespread adoption of sustainability claims, yet the prevalence of greenwashing—where organizations make misleading environmental claims—threatens genuine sustainable development efforts. Environmental Product Declarations (EPDs) have emerged as a potential solution, particularly in the New Zealand and Australia construction sectors, where recent government climate regulations have accelerated their adoption. However, the effectiveness of EPDs in combating greenwashing and their practical implementation remain understudied. This research addresses this gap through a comprehensive analysis of EPDs in construction, employing a systematic literature review of 82 articles from 2010 to 2024 across major databases. Using ATLAS.ti 9 software, this study makes three key contributions: (1) develops a novel framework for evaluating EPD programs and their effectiveness in preventing greenwashing, (2) establishes a standardized methodology for assessing the completeness and accuracy of life cycle assessment information in EPDs, and (3) provides evidence-based recommendations for improving EPD implementation in the construction industry. The findings reveal critical shortcomings in current EPD practices, including inconsistent assessment methodologies and incomplete life cycle data. This study proposes specific reforms to enhance EPD reliability and transparency, offering practical guidelines for industry stakeholders to verify environmental claims. These contributions advance both the theoretical understanding of environmental certification systems and practical implementation of sustainable construction practices by developing regulatory frameworks.

    The Potential Challenges and Limitations of Implementing Modern Office Design Features in Residential Spaces: A SPAR-4-SLR Approach
    (MDPI AG, 2024-09-24) Rotimi JOB; Moshood TD; Rotimi FE
    The COVID-19 pandemic has significantly altered how people work, with an increasing number transitioning to working from home (WFH). This paradigm shift has raised various challenges in adapting living spaces to meet the needs of remote work. Dedicated workspaces or home offices need to be customized for creativity and productivity. Thus, this systematic literature review explores the potential challenges and limitations of implementing modern office design features in residential environments. The study synthesizes findings from 108 peer-reviewed articles published within the last decade, focusing on ergonomics, productivity, work–life balance, and spatial constraints. The study found several challenges in translating office design features to home settings. Firstly, spatial limitations in residential areas often restrict the implementation of open-plan layouts and collaborative zones, which are hallmarks of modern office designs. Secondly, the integration of ergonomic furniture and adjustable workstations are limited by budget constraints and the dual-purpose nature of many home spaces. Furthermore, the review highlights the psychological challenges of maintaining work–life boundaries when professional and personal spaces overlap. Noise pollution and distractions emerge as significant factors impacting productivity in home offices, which contrasts controlled modern office environments. The review suggests that the complete replication of modern office design in homes may be impractical; a hybrid approach that adapts key features to residential constraints could enhance home office productivity. Potential solutions could include modular furniture designs, the simulation of collaborative spaces, and the development of noise-cancelling technologies specifically for home environments. This study contributes to the growing body of knowledge on remote work environments and provides valuable insights for enhancing work–life balance, environmental sustainability, and economic growth.

    The “Other” Workplace Design Factors: An Insight into What New Zealand Workers Want
    (MDPI AG, 2024-09-26) Rotimi JOB; Rasheed EO
    The recent COVID-19 pandemic has led to a reassessment of workplace necessities. It has resulted in the current shift from traditional workplace design to creating work experiences—a new paradigm in workplace management. Hence, while some conventional workplace factors remain important to the experiences of workers and, thus, to their well-being, comfort, and productivity, recent studies suggest other factors, not widely known, as important in creating the appropriate work experience. Our study explores these other factors in the workplace that contribute to or may be very important to, workers’ comfort, well-being and productivity. These include working mode; facilities; sustainability practices; and diversity, equity, and inclusion (DEI)—cultural connection. A sample of 149 occupants across offices in New Zealand was conveniently collected for the study and analysed using descriptive and content analysis in SPSS v24. The results show that the occupants prefer to have private offices in the workplace and separate meeting rooms for better concentration on work. In terms of working mode, a combined model of remote working and in-office working is preferred. Furthermore, occupants prefer to have access control and fire safety systems essentially in the workplace and for their offices to be cleaned daily. For sustainable measures in the workplace, the respondents choose the following as practical and convenient: turning off computers outside work hours, using more LED light bulbs in the office, opening windows and doors when required, and using a motion sensor lighting system. Interestingly, most of the respondents did not think having a cultural connection in their workplace was important. The study findings represent significant progress in identifying the needs of contemporary office workers. These findings assist facility managers and workplace designers in developing more proactive approaches to anticipated user issues in buildings.
