Hand Calculate Fan Energy Savings
Hand calculating fan energy savings is crucial for understanding and reducing your energy consumption. Fans account for a significant portion of energy usage in many facilities. By calculating energy savings, you can make informed decisions about fan maintenance, replacement, and operation.
How to Use This Calculator
- Enter the fan’s cubic feet per minute (CFM) rating.
- Enter the fan’s voltage.
- Select the number of hours the fan operates daily.
- Click the “Calculate” button.
Formula & Methodology
The calculator uses the following formula to estimate energy savings:
Energy Savings (kWh) = (CFM * Volts * Hours * 0.746) / 1000
Where:
- CFM: Cubic feet per minute
- Volts: Fan voltage
- Hours: Daily operating hours
