Energy and water are among NC State’s most necessary and costly expenses. For more than a decade, the university’s campus-wide energy management strategies have enabled significant conservation of vital fiscal and environmental resources.

Annual Energy and Water Report

The Energy and Water Report for Fiscal Year 2022 provides an update on campus progress toward utility reductions, highlights specific projects and outlines strategies for the next fiscal year that will contribute to further reductions.

Energy Consumption

Campus energy consumption peaked in fiscal year 2009 and has trended downward since. Reduced occupancy on campus during the pandemic produced a greater energy reduction in 2020 and 2021 than would have otherwise been achieved. Energy-intensive Covid-19 mitigation strategies such as higher air filtration, increased outdoor air levels and longer hours of HVAC operation to allow flushing of air before and after building occupancy for safety increased energy usage in 2021-2022. Compared to the FY 2003 baseline, total energy consumption per gross square foot (GSF) has decreased by 35% in FY 2022.

Water Consumption

In fiscal year 2016, NC State began utilizing non-potable reuse water supplied by the City of Raleigh on Centennial Campus. Reuse water is wastewater treated to a high standard and reused instead of being discharged into a waterway. Reuse water provides a more cost-effective and drought resistant supply of water for cooling towers, irrigation and toilet flushing. For total water consumption (potable and reuse), FY 2022 marked a level 51% below the FY 2002 baseline with potable water consumption decreased by 59%.
