INDICATORS OF ENVIRONMENTAL AND PRODUCTIVITY PERFORMANCE FOR BUILDING REFURBISHMENT PROJECTS

Since the end of the 1990s, much has been written on construction key performance indicators but little on indicators for building refurbishment, although indicators for road and sewage refurbishment are in use. The purpose of this paper is to formulate principles for developing building refurbishment productivity and environmental performance indicators. When starting from traditional productivity measures, also including effects on client productivity, and from environmental sustainability measures, it is necessary to ask why firms rely on performance measures and why they collect certain types of data. Literature in the areas of performance measurement, key performance indicators, sustainability and productivity has been reviewed and applied to a refurbishment context. When developing new indicators for refurbishment projects, it is important to consider practical issues such as resources required to collect data, including both leading and lagging measures, waste management, local, negative disruptions and effects on user satisfaction, consequences of coproduction, changes in input and output qualities and client productivity
