To design effective energy-saving strategies, it is essential to understand how the energy is used by the different building systems and spaces. However, available energy consumption data for the UIUC campus are only at the building level. This project aims to outfit a building(s) with sub-metering devices to collect granular and fine data on building energy consumption end-use. The collected data would help improve our understanding of building energy-use and consequently help identify more effective energy-saving strategies for improving campus sustainability. The collected data will be available online to all UIUC students, as well as Facilities & Services staff. The sub-metering system will be located on the second floor of the Hydro-Systems Laboratory.
