    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.

    Enhancing Construction Waste Management in New Zealand: Lessons from Hong Kong and Other Countries
    (IOP Publishing, 2023-10-06) Doan, Dat Tien; Albsoul, Hadeel; GhaffarianHoseini, Ali
    Global construction waste (CW) poses escalating environmental, social, and economic challenges. While New Zealand grapples with a dearth of research on optimal construction waste management (CWM) techniques, it stands to gain from the comprehensive practices employed in regions like Hong Kong. Drawing from the extensive literature on CWM practices in Hong Kong and other countries, this study seeks to furnish New Zealand's construction professionals and policymakers with invaluable insights. Key findings illuminate the determinants of successful CWM, the motivations steering stakeholder behaviour towards CW reduction, the transformative potential of public policy, and innovative enhancement strategies. The research underscores the instrumental roles of green building and big data in CW curtailment, delving into the attendant challenges and rewards. By assimilating lessons from these international paradigms, New Zealand is poised to refine its CWM, catalysing a shift towards a more sustainable construction landscape.

    Estimating Construction Waste in New Zealand: A Focus on Urban Areas, Residential and Non-residential Building Activities
    (IOP Publishing, 2024-02-26) Albsoul, Hadeel; Doan, Dat Tien; GhaffarianHoseini, Ali
    This paper examines the significant increase in construction waste (CW) due to urbanisation and population growth in New Zealand and worldwide. The aim is to estimate CW using available data in New Zealand and identify relevant indicators to employ estimation methods. Various methods and models for estimating CW at the urban level and from building activities are reviewed. According to the best available data, the paper uses the per-capita multiplier and waste generation rate methods to estimate CW in New Zealand. New Zealand's per-capita multiplier for CW is 943.46 kg/per capita. The waste generation method using the floor area indicator is applied at residential and non-residential building levels. The estimated CW in 2021 was 531,109 tonnes for residential and non-residential buildings using the floor area indicator. The findings reveal a positive relationship between residential building activity and population growth, with Auckland generating the highest rate of CW. Because of the limitations of the available data and estimation methods, the paper highlights the need for standardised data collection systems and outreach programs to improve CW estimation practices. Further research is recommended to enhance waste reduction strategies and identify high-waste-generating materials and methods. It is vital to have accurate CW estimations to support project waste management plans and sustainable construction practices and to inform waste management policies and regulations at the regional or national level.

    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.
