CFU 5-Star Home Program
Through the CFU 5-Star Home Program, CFU customers building new homes can qualify for a 25% electric discount. In homes heated by natural gas, the 25% discount on the electric bill is good for the first four years. Homes with electric heating can earn the 25% electric discount for the first two years. To qualify, new homes must meet the energy efficiency standards listed below. CFU Energy Services staff reviews building plans for model energy code compliance, and will advise customers about eligibility for the 5 Star Home program as part of the plan review. During construction, the home must pass CFU air-sealing and insulation inspections. | Equipment | CFU-Certified 5-Star Standards | | Cooling | - Central air conditioner must be minimum 16.0 SEER
