The following calculation demonstrates the savings that can be obtained in a typical hotel/motel installation by replacing existing PTACís with RetroAire units:
- Number of Rooms: 120
- Occupancy Rate: 85%
- Annual Cooling Days: 50%
- Energy Cost: $.08/KWH
- Estimated Efficiency Gain w/ RetroAire Replacement = 150 Watts per Hour
8,760 Hr/Yr x 120 Units
x .85 Occupancy x .50 Cooling Demand
x 150 WATTS/1,000 = 67014 KILOWATTS
Estimated Annual Savings
with RetroAire replacements:
67014 KWH x $.08/KWH= $5,361.12
Substitute your own numbers and see what a RetroAire upgrade can mean to you.
Substantial energy savings can actually pay for your upgraded equipment.
