Provision of adequate and affordable housing is a major challenge in both emerging and industrialised countries. With increasing urgency for addressing climate change and other environmental issues these habitats will need to be environmentally sustainable too. Conventional construction, especially in dense urban centres and in rural or remote areas, is putting great pressures on cost and resource efficiency and is compelling the industry and governments globally to question the approach of business-as-usual. Prefabrication or off-site construction can offer great opportunities for both environmental and economic performance and hence is emerging as an attractive alternative to on-site construction. Although in the established markets the share of prefabrication in overall construction output remains strong, in many countries including Australia it still remains in its infancy. In order to enhance the profile of prefab housing and effectively develop high performance sustainable and affordable housing it is vital that first the needs and perceptions of the industry on these issues are adequately studied.
This paper relates to the first of a two part research project aimed at exploring the makeup of the prefab housing industry and identifying various challenges and opportunities. The study was conducted as an international industry survey in which barriers, opportunities, performance and perceptions of sustainability and affordability were explored. The paper presents the results of this survey. Based on a cross-sectional analysis the responses are compared and categorised. Among other things the findings highlight the gaps in the understanding of the relationship between sustainability and affordability. This research contributes to the discourse on the need to better understand the role of design and design decision making for developing high performance prefab housing.
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
Financing the upfront costs of energy efficiency and renewable energy projects in buildings can be a significant barrier to the expansion of sustainable, low carbon buildings, despite this being a low-cost option on the carbon abatement curve. Systematic literature on...Read more
Rapid global urbanization and the increase of the Urban Heat Island (UHI) effect make urban cooling a necessity as well as an opportunity to increase the liveability and amenity of cities. This review is a scoping study of the relevant worldwide UHI mitigation/adaptation...Read more
Sustainability assessment tools aim to promote high sustainability outcomes in residential buildings, ensuring less consumption of water, energy and less emission of greenhouse gases. However, existing literature often presents variations between the estimated outcomes from the assessment tools and actual outcomes after building occupation.
This book focuses on the challenge that Australia faces in transitioning to renewable energy and regenerating its cities via a transformation of its built environment. It identifies innovative and effective pathways for decarbonising the built environment from applied research undertaken by the Co-Operative Research Centre for Low Carbon Living.
This report presents a summary of all the findings and activities performed in the LCL-CRC research project RP1011 “Sustainable and affordable living through modular homes and communities” and represents the culmination of the project.
