    Developing a Framework for Construction Sector Capacity
    (UTS ePRESS, 2022-11-28) Le ATH; Domingo N; Macgregor C; Potangaroa R
    Understanding construction sector capacity allows stakeholders to assess the ability to deliver construction projects critically. However, the capacity concept in the construction sector is dynamic, and interrelationships of capacity at different levels have not been explored thoroughly. Accordingly, this paper reviewed studies on capacity at different levels: sector, organisational, and individual to (1) identify attributes of capacity at each level; (2) map relationships of the capacities in the construction sector; and (3) develop a conceptual framework of project capacity in the construction sector and propose future research directions. This study used an integrative literature review approach to synthesise literature from various domains to describe different levels of the construction sector’s capacity. The findings of the literature review conceptualised a construction sector capacity framework at four levels: sector, organisational, individual, and project. The detailed descriptions of the relevant attributes at each level advance our understanding of capacity within the construction sector and are fundamental to developing capacity assessment tools for the construction sector. The relationships formed in the proposed framework help explain how the capacity at each level affects the system. Findings also serve to identify areas for future research, including investigating interrelationships of attributes in the capacity framework.

    Zero carbon refurbishment for existing buildings: A literature review
    (IOP Publishing Ltd, 2022-01-01) Bui TTP; Domingo N; Macgregor C; Wilkinson S
    The need to mitigate climate change calls for the construction industry to achieve net-zero greenhouse gas (GHG) emissions for new and existing buildings by 2050. Zero carbon refurbishment (ZCR) for existing buildings is a significant area of interest, as many existing buildings will still be there in 2050. This paper investigates the global development, knowledge structure and gaps in the research field by conducting a systematic literature review. The final selection of 147 up-to-date journal articles was analysed using mixed-method data analysis, including quantitative (science mapping) and qualitative (thematic) analysis. Quantitative results reveal evolving research topics including energy performance and efficiency, life cycle environmental impacts, energy resources and policy, and decision-making with multi-objective optimisation. Research in ZCR is well-established in European countries and there is much interest and activity around the world. ZCR research on residential and office buildings provokes much consideration compared to other building types. The qualitative findings discuss the mainstream research areas (e.g. decision-making with multi-objective optimisation), determines research gaps (e.g. carbon impact), and recommends the future research agenda. The study offers academics a comprehensive understanding of ZCR research to link current research areas into future trends. It also provides construction professionals with current practices and an interdisciplinary guide to better deliver ZCR projects.
