SAU Energy Talking Points
• SAU per square foot energy cost of $1.20 is among the most efficient in the state.
• District Heating and Cooling Systems save 30% on annual electricity cost and 15% on annual gas cost over conventional stand-alone systems.
• Estimate Annual Savings: Electricity: $282,862 Gas: $ 58,437
Total $341,299
SAU District Cooling SystemPhase XIII Completed This Year
SAU Energy Talking Points• Selecting energy efficient equipment has resulted in
approximately $100,000 in rebates from power and gas companies over the past 5 years.
• $2.5M AARA funding and $1.6M RLF funding spent on energy efficiencies over past 4 years. In the 2010/2011 FY, SAU experienced a 21% reduction in KWH, and 11% reduction in demand charges and a cost reduction of 35%. However, record heat waves, 14% increase in new construction square footage, a 115% increase in water unit cost , 47% increase in wastewater unit cost and a 7.9% increase in student enrollment and associated OPTEMPO have offset some of these savings.
SAU Energy Talking PointsReference following 5 year history of energy usage and
cost charts: Factors Influencing Usage & Cost• Square footage increased by 14%.• Student population increased by 7.9%• Student activity and OPTEMPO increased proportionally.• Water unit price increased by 115%• Wastewater unit price increased by 47%• Experienced hottest summer months on record during
2009-2012 period.
SAU Energy Talking Points Performance Indicators (Based on 5 Year Average)• Overall utility cost increased by only 6% ($1.20 per square foot).• Electrical usage increased by 4.6%; cost increased by 0.4%.
(Electricity is 60% of overall cost).• Gas usage increased by 15%; cost decreased by 14% due to
significant reduction in unit market cost. (Gas is 21% of overall cost.• Water usage increased by 22%; cost increased by 102% due to 115%
increase in unit price and increased usage (Water is 11% of overall cost).
• Wastewater usage increased by 135%; cost increased by 96% due to 47% increase in unit price and increased usage. Wastewater is 8% of overall cost.
