Annual energy savings
923.1 kWh/yr
Old system usage
3,323.1 kWh/yr
New system usage
2,400 kWh/yr
Estimated cost savings
138.46 $/yr
Formula and working
kWh = (BTU load × hours) ÷ SEER2; savings = kWh_old − kWh_new
- 1
Collect the inputs
Cooling capacity = 36,000 BTU/hr; Annual cooling hours = 1,200 hr/yr; Existing SEER2 = 13; New SEER2 = 18; Electricity rate = 0.15 $/kWh
- 2
Apply the formula
kWh = (BTU load × hours) ÷ SEER2; savings = kWh_old − kWh_new
- 3
Result
Annual energy savings = 923.1 kWh/yr
