Building sustainability assessment methods

Over last 15 years it has been increasingly important to understand the sustainability performance of buildings across a broad range of considerations. This has stimulated the development of a number of sustainability assessment tools intended to measure objectively a project's impact in sustainability terms and so encourage designers and planners to improve a building's performance. This paper examines the nature and contribution, as well as the limitations, of current sustainability rating assessment tools in evaluating building sustainability in different countries. Two yardsticks are used to review the current tools: first, how well they relate to the goal of sustainable development, and second, how adequately they adhere to the principles of objective assessment. Scope for further development of sustainability assessment tools is identified – in particular, the need for tools to assess more adequately how buildings provide well-being, and to expand how assessment systems capture qualitative information. The paper proposes that methodology and procedures of assessment methods should feature the broad participation of user groups drawn from the public.
