Phase 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.
