Working Paper - Currently Submitted

Keywords: Energy Efficiency Ratings, Disclosure, House Prices, ACT

This paper seeks to elucidate whether high levels of non-disclosure lead to adverse market outcomes in the form of the well-known lemons problem. It also empirically tests whether energy-efficiency ratings (EERs) are reflected in both housing sales prices and rents in the Australian Capital Territory, the only Australian housing market with mandatory ratings for all dwellings at point of sale or lease. Using a comprehensive dataset of sale and lease transactions during the period 2011–2016, a hedonic framework is applied. The analysis confirms that both the reported energy-efficiency levels and other sustainability-related characteristics that are not part of the formal rating assessment influence the pricing of both sales and rental transactions. Characteristics such as heating and cooling systems and the presence of solar power generators are significantly reflected in rents and sales prices, as tenants and buyers are likely to estimate their expected utility costs based on the EER. It is also shown that the option of leaving the EER of a rental property unreported presents a moral hazard for landlords of sub-standard properties, in that the likelihood of EER disclosure increases in line with the number of energy-efficient features of a property as revealed in the marketing material.

9 Step guide to facilitating Regenerative Development
– fostering Living Environments in Natural, Social and Economic Systems

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
2016
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.

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

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
Routledge
2015
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 - https://www.academia.edu/30298725/CH1_Designing_For_Hope_-_Why_do_we_need_regenerative_sustainability
