The increasing importance of sustainability for building ownership

Purpose — This study seeks to investigate the degree to which energy efficiency is incorporated into office building refurbishment and capital expenditure with the emphasis placed on a cost-benefit analysis from the owner’s perspective. Design/methodology/approach – In order to develop a research framework, a thorough literature review was conducted of three disciplines being construction technology, building refurbishment and property management. The study identifies differences between varying levels of capital expenditure to ensure an existing building is more energy efficient, with the emphasis placed on the cost of implementation and the potential for tenants to acknowledge the increased energy efficiency via higher rents. Findings – Office buildings have been identified as a contributor to global warming during the construction phase, however during the building lifecycle there is a greater contribution to CO2 omissions. Whilst various building designs and construction techniques have evolved to improve energy efficiency, the focus has largely been placed on new buildings where it is easier to incorporate change and innovative approaches. However, the proportion of new buildings constructed each year is relatively small in comparison to existing building stock, which requires regular capital expenditure to maintain and attract new tenants within a competitive marketplace. Practical implications – The increasing importance of energy efficiency affects the office market in a variety of different ways. Originality/value – This paper identifies important links between the environment and the built environment, and the implications for office building owners

Analysis of the transition effects of building codes and regulations on the emergence of a low carbon residential building sector

© 2017 Elsevier B.V. It is now established that energy use in buildings is a significant source of global greenhouse gas emissions and that abatement by the building sector can provide significant social, economic and environmental benefits. This paper examines the application of socio-technical transition theory to the building sector with Australian energy policy as a case study. The relatively high level of local building construction offers significant opportunities for market transition with appropriate policy settings so this national case has international implications. Evolution of building energy efficiency standards through the Australian National Construction Code is scrutinized by benchmarking the building energy code against international best practice. The benchmarking underscores the contribution high performance energy efficient buildings could make to a low carbon transition with appropriate policy settings. Specifically government intervention in the building sector through direct regulation was shown to have substantial potential to effect this transition. Nevertheless, such intervention has proven to be politically controversial in Australia. The paper provides a twofold contribution to research in the domain of building energy policy. Firstly, by making the connection between transition theory and the role of building energy codes; secondly, by demonstrating the practical application and utility of a structured building code benchmarking process
