Energy Smart Tool is an online performance-based building energy benchmarking tool developed by the Energy Sustainability Unit (ESU), Department of Building, School of Design and Environment, National University of Singapore, supported by European Union through the EU-ASEAN Energy Facility, and National Environment Agency of Singapore and Jurong Town Corporation Singapore. The main objective of the Energy Smart Tool is to provide comprehensive, reliable and accurate benchmarks of energy consumption and efficiency in buildings. This tool is intended to be a starting point in assessing building energy use and saving potential. It provides you with a direct comparison of your building energy performance among the total cohort of similar facilities, which can help to identify the position of your facility, and to set energy and efficiency targets.
