    A Review of Extant Literature and Recent Trends in Residential Construction Waste Reduction
    (SAGE Publications, 2024-04-10) Albsoul, Hadeel; Doan, Dat Tien; Aigwi, Itohan Esther; GhaffarianHoseini, Ali
    The residential construction sector in New Zealand and worldwide is experiencing increased criticism for generating substantial waste that poses environmental concerns. Accordingly, researchers have advocated implementing residential construction waste reduction (RCWR) strategies as a sustainable solution to managing construction waste (CW). This article aims to provide a comprehensive overview of RCWR by analysing 87 articles from the Scopus database using bibliometric and critical review methods. The co-occurrence analysis of keywords revealed five clusters, in which five main themes emerged: (i) waste generation and management performance, (ii) prefabrication and life cycle assessment concepts, (iii) design concepts, (iv) circular economy and (v) decision-making concepts. The findings suggest that sustainable practices such as designing for waste reduction, prefabrication, waste quantification, three-dimensional printing and building information modelling can effectively achieve RCWR. The study also highlights the benefits of RCWR, including reducing environmental impacts, and identifies management, economic, legislative, technology and cultural barriers that affect the implementation of RCWR strategies. These results provide valuable insights to support future policy formulation and research direction for RCWR in New Zealand.

    Examining Critical Factors Affecting the Housing Price in New Zealand: A Causal Loop Diagram Model
    (Springer Science and Business Media LLC, 2023-12-26) Albsoul, Hadeel; Doan, Dat Tien; Aigwi, Itohan Esther; Naismith, Nicola; Ghaffarianhoseini, Amirhosein; Ghaffarianhoseini, Ali
    The New Zealand housing market has become a public concern due to the significant surge in housing prices. The steep increase in housing prices has presented significant difficulties for individuals seeking homeownership, particularly for first-home buyers. Therefore, this research aims to identify the crucial factors of the New Zealand housing price system and their influence on housing prices. The system dynamics (SD) methodology was applied to organise the cause and effect variables into a causal loop diagram (CLD) illustrating the structure and interaction of the primary feedback mechanisms within the complex system of housing prices. Accordingly, population growth, macroeconomic stability, investment demand, monetary policy, and construction costs are key contributing factors to promoting affordable housing prices and increasing homeownership rates in New Zealand. The construction costs, including the land cost, are the most significant of all the factors. Hence, there is a call to prioritise optimising construction resources. This research’s developed model was validated by exploring experts’ views on the model’s components and system dynamics. The findings provide relevant stakeholders in New Zealand’s residential construction sector with solutions and guidelines for coping with supply and demand fluctuations and reducing economic cycles on material price and workforce development.

    Public Perception of Heritage Buildings in the City-Centre of Invercargill, New Zealand
    (Elsevier BV, 2023-08-30) Aigwi, Itohan Esther; Filippova, Olga; Sullivan-Taylor, Bridgette
    With the global advancement in heritage conservation and sustainable management practices, understanding the public perception of built heritage is crucial. This paper examined the public perception of heritage buildings in the city centre of Invercargill, New Zealand, using an online survey to gather relevant information from over 600 participants. The results showed significant support (73.8%) for Invercargill City Council (ICC)'s district plan heritage list to be narrowed down as recommended by professional heritage consultants. There was also substantial support (72.6%) for heritage recognition of some recommended 26 buildings to be removed from ICC's district plan so that ICC can focus more on conserving fewer heritage buildings with significant values in the city centre. Many participants (66.1%) believed that a well-maintained heritage building and access to local government incentives should be the critical determinants for a heritage building to stay on ICC's heritage list. In addition, open-ended responses mainly emphasised the safety concerns of earthquake-prone heritage buildings and the expensive costs of seismic upgrades, suggesting the ‘demolition and rebuild’ of irrelevant heritage buildings as a feasible solution to redeveloping Invercargill's declining city centre. This study's findings revealed the significance of local knowledge of relevant built heritage parameters in Invercargill and its role in enhancing the usefulness of macro-level heritage projections and local built heritage conservation initiatives. These insights could serve as a starting point towards formulating a sustainable management plan for cities worldwide with ‘fast disappearing’ inner-city heritage buildings – a topic of interest for relevant built heritage conservation enthusiasts.

    Unlocking the Potentials of Sustainable Building Designs and Practices: A Systematic Review
    (Elsevier BV, 2024-12) Poorisat, Tharaya; Aigwi, Itohan Esther; Doan, Dat Tien; GhaffarianHoseini, Ali
    Sustainable building designs and practices are gaining traction as a blueprint for constructing eco-friendly and economically viable buildings that can enhance the quality of life for occupants. This study presents a comprehensive analysis of the characteristics, drivers and barriers of existing sustainable building designs and practices using the Systematic Literature Review (SLR) process. Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocol, 40 characteristics, 63 drivers, and 48 barriers of sustainable building designs and practices were identified, categorised and analysed from peer-reviewed articles (n = 130) published in the Scopus database between 2013 and 2023. Accordingly, the categorised characteristics (i.e., energy efficiency, indoor environmental quality, sustainable sites, water efficiency, economic aspects, material and resources, waste management and social equity), drivers (i.e., financial and economic, environmental protection, policy and government-related, technological, educational awareness, health and socio-cultural, and organisational and marketing) and barriers (i.e., financial and economic, policy and government-related, technological, organisational and marketing, educational and awareness, and socio-cultural) were discussed, and recommendations provided. This study’s findings will serve as a crucial benchmark for relevant stakeholders, including governments, investors, building professionals, and researchers, to foster progress in the built environment field and encourage more sustainable approaches to building design and practices.
