Research conducted by The Warren Centre in 2009 (Low Energy High Rise Project – stage 1) showed that there was a strong link between the implementation of low and no-cost initiatives and the energy efficiency performance of commercial buildings demonstrated through improved NABERS (performance-based rating system for existing buildings) Energy ratings. These findings demonstrated that energy efficiency could be improved at very low or no capital cost amounting to a potential 1 star improvement. The Low Energy High Rise Project began with Stage 1 in 2007 to examine the factors influencing energy efficiency in high rise office buildings.
This world first project found that there was significant differences in energy efficiency and established the first empirical data to relate operational behaviour to energy efficiency outcomes. Following the completion of the Stage 1 Project, Stage 2 set out to develop information to assist building operators in the implementation of energy efficiency strategies and behaviours.
