Keywords: Australia, clients, demand-supply model, innovation, residential construction

Adopting sustainability as an innovation in the Australian residential construction sector is constrained in an industry characterized by mass produced standardized new home production. Traditionally perceived as supply-led the residential construction procurement model inhibits the ability of consumers to demand change, or for innovation to be consumer demand-lead. This research adopted Heywood and Kenley’s consumption-based demand and supply model for corporate real estate as a framework for understanding the roles and relationships in the Australian residential construction industry, in particular the volume homebuilder as a key client for innovation from its supply chains. The investigation provides an informed understanding of demand and supply-side structural relationships in the residential procurement process. The research identifies how innovation and change, particularly towards more sustainable homes, can be enabled through the Australian residential housing industry’s current mechanisms.
Investigating demand-side stakeholders’ ability to mainstream sustainability in residential property

Keywords: Homebuyers; supply chain framework; sustainability; residential property; volume homebuilders

Current sustainability approaches in the residential property sector for new home construction are deficient, yet crucial in reducing reliance on finite resources whilst providing better social outcomes. At present, efforts to improve dwelling sustainability are inhibited: as sustainability is considered an overly expensive additional extra; there is poor implementation of energy efficiency regulations; unempowered consumers are unable to demand sustainability and consumers distrust the suppliers of sustainable initiatives. This research addresses an important issue to eliminate the “blame game” and transform the sustainability conversation, adoption and value in new home markets. It adopts an innovative demand-side approach to the residential property sector, in order to target largescale standardised new home producers as the pivotal, demand-side player in mainstreaming sustainable solutions in new housing. By examining the sector from this new perspective, sustainability can be mainstreamed in the new housing property sector overcoming current inhibitors to sustainability adoption and implementation.
Mainstreaming Sustainability in the Housing Sector: a New Approach to an established process

Keywords: Australia, sustainability, innovation, residential construction

The operation of the Australian residential sector is currently inhibiting and preventing the mainstreaming of sustainability in the construction of new homes. The established approach to housing construction in the Australian market applies a traditional design and construct approach, which has been industrialised, to mass-produce new homes. This approach has evolved an ogliogpoly of housing providers that limits the incorporation of sustainability for new homes under this traditional old world design and construct approach to housing delivery. For innovation and sustainability to achieve real change within this sector, a new perspective and approach is required to drive innovation and adoption of sustainability in new homes to minimise the long-term environmental, social and economic repercussions that could burden current and future generations in Australia. This research has investigated and identified a new framework that utilises a consumption-based demand and supply model to identify the key stakeholders that have the power to drive societal change for increased adoption of sustainability in new homes. Utilising semi-structured interviews of major Volume Building housing providers in Australia the consumption-based demand and supply model has been tested and verified. For the first time the research will provide an innovative re-examination of demand stakeholders’ roles and expose…
Volume Home Building: Sustainability Inclusions for New Homes

Pacific Rim Real Estate Society Conference
Keywords: Residential Construction, Volume Builders, Consumers, Sustainability, Australia

Purpose: This paper investigates the provision of sustainability related inclusions in the standard inclusions lists for new homes offered by the HIA’s top 100 homebuilders and that are available for download from their websites. Homebuyers are identified as being a key reason for the limited uptake of sustainability initiatives in new housing. However, if homebuyers are unaware of options, features or information relating to sustainability, how can they make informed decisions in the new home building process? Consequently, homebuyers engagement in sustainability are guided and influenced by the information provided to them from professionals in the sectors, in particular the volume builders. The purpose of this research is to examine a key source of information and provides insight into the structural, lifestyle and sustainable features that a homeowner will have in their completed home, such as sustainability features. Approach/method: The research utilises content analysis of standard inclusions collected from websites of the HIA’s top 100 homebuilders in Australia to identify the type and information provided regarding sustainability features in standard inclusion lists for new homes. Findings: This paper highlights the limited range of sustainable inclusions that Australia’s top builders are drawing on when designing and constructing homes for new homebuyers.…
9 Step guide to facilitating Regenerative Development
– fostering Living Environments in Natural, Social and Economic Systems

Keywords: LENSES, Regenerative Development, Regional Development, Master plan

The concept of regenerative development is gaining traction. Let’s face it, it is a compelling thought that our projects cannot just alleviate social, ecological, and economic issues but foster potential and innovation to thrive. What is not less known is the process to achieving such a project. While many developments are claiming the title ‘regenerative’, they often support elements of one sphere more than the others. Hence, it is important to go through a flexible and holistic process that ensures you consider every element and challenge your thinking process to identify whether the strategies drafted for them are patching up a problem or creating long-term benefits. For the past year, the Thrive Research Hub has supported the Seacombe West Design Team and Project Managers to achieve a master plan that could result in regenerative outcomes. This was done by applying the Living Environments in Natural, Social and Economic Systems (LENSES) framework. The philosophies embedded in this framework are represented through three overlaid lenses: the foundation lens (in green) highlight guiding principles important for every project, the flow lens (in blue) indicate the fluid elements that impact and are impacted by the project, and the vitality lens (in yellow) which reminds…
Towards Buildings that Thrive
Thrive team
The University of Melbourne
Keywords: Health and Wellbeing, Resource Efficiency, Systems Approach, Economics, Buildings of the Future

This report outlines some of the key problems associated with the way in which we currently design, construct, operate and manage our buildings. The critical areas covered include health and wellbeing, natural resources, fragmented decision-making and economics. It then presents a range of strategies for addressing these problems and creating buildings that are much more efficient in their use of resources, are healthier places for people to live and work in, and ultimately make a positive contribution to the environment, social wellbeing and building performance. A range of case studies are used to reinforce both the extent of the problems and urgent need to address them as well as demonstrate how suggested strategies can be used to produce buildings that help protect our fragile ecosystems, are healthier, and most importantly, help people to thrive.
Cool Roof Retrofits as an Alternative to Green Roofs
Hes, D., Jensen, C. and Aye, L.
John Wiley & Sons, Ltd.
Keywords: Cool roofs, Urban Heat Island, Green roofs, Albedo

Cool Roof Paint (CRP) is a practical, low cost and popular retrofit option for improving the thermal performance of buildings in locations where there are significant cooling loads. This chapter looks at their viability in a more cool-temperate climate where there is a higher heating load. The chapter presents the results of four experiments investigating a CRP roof retrofit of a twenty year old metal roof; the extension of this data through modelling to test the sensitivity of CRP to changes in shading, roof pitch, insulation levels, insulation location and building roof to surface areas ratios; the testing of the CRP against a green roof retrofit and finally the benefit of white roofs on electricity production through Photovoltaics.
Life Cycle Assessment in the Built Environment

Taylor and Francis
Keywords: Life cycle assessment, buildings, built environment, case studies, sustainable building

After outlining the framework for life cycle assessment, this book uses a range of case studies to demonstrate the innovative input-output-based hybrid approach for compiling a life cycle inventory. This approach enables a comprehensive analysis of a broad range of resource requirements and environmental outputs so that the potential environmental impacts of a building or infrastructure system can be ascertained. These case studies cover a range of elements that are part of the built environment, including a residential building, a commercial office building and a wind turbine, as well as individual building components such as a residential-scale photovoltaic system. Comprehensively introducing and demonstrating the uses and benefits of life cycle assessment for built environment projects, this book will show you how to assess the environmental performance of your clients’ projects, to compare design options across their entire life and to identify opportunities for improving environmental performance.
Designing for Hope: Pathways to Regenerative Sustainability
Dominique Hes and Chrisna du Plessis
Keywords: Regenerative Development, Regenerative Design, Biophilia, Biomimicry, Positive Development, Contributive Practice, LENSES framework, Living Building Challenge; Ecological Worldview

A forward-looking book on sustainable design that describes problems and then, by providing a different way to conceptualize design and development, leads on to examples of regenerative solutions. Its aim is to move the discussion away from doing less, but still detracting from our ecological capital, to positively contributing and adding to this capital. This book offers a hopeful response to the often frightening changes and challenges we face; arguing that we can actively create a positive and abundant future through mindful, contributive engagement that is rooted in a living-systems-based worldview. Concepts and practices such as Regenerative Development, Biophilic Design, Biomimicry, Permaculture and Positive Development are explored through interviews and case studies from the built environment to try and answer questions such as: ‘How can projects focus on creating a positive ecological footprint and contribute to community?’; ‘How can we as practitioners restore and enrich the relationships in our projects?’; and ‘How does design focus hope and create a positive legacy?’ Download 1st chapter here -
