Measures of environmentally sustainable development and their effect on property asset value : An Australian perspective

Purpose – The global market for sustainable buildings is growing, albeit from a slow start, as awareness of the consequences of climate change begin to influence the corporate decision makers seeking new office accommodation. Research has shown that a circle of blame has prevailed in recent times resulting in few sustainable buildings being developed. The recent growth of the Green Star and NABERS rating schemes is testament to the need to establish market recognisable measures of environmentally sustainable development (ESD) against which developers, occupiers, and owners can benchmark their sustainability credentials. The developer's and owner's dilemma that has emerged from the uncertainty as to what a sustainable building is, has been one of; can I afford the added cost of ESD or, more particularly, can I afford not to build ESD? A more precise question that is being asked is how many green stars do I actually need? This paper aims to examine the growth of the rating systems in Australia and the issues facing developers, owners and valuers in establishing the viability of ESD. Design/methodology/approach – This study examines the growth of the environmentally sustainable building rating systems in Australia and the issues facing developers, owners and valuers in establishing the viability of environmentally sustainable design (ESD). It explores the occupiers'/corporate real estate perspective looking at workplace and triple bottom line performance as well as issues relating to green leases in ESD premises. Findings – Results from this study suggest that building owners and developers are seeking to develop and own buildings with ESD credentials and that there is a growing demand for these buildings from occupiers. The study shows that currently there is a focus on rating buildings at the design stage rather than as constructed, and that there is a need to develop consistent rating tools to enable valuers to evaluate buildings on a like for like basis. Originality/value – This study analyses data on green building ratings and evaluates the growth of ESD rating systems in the Australian market.
