1. What Is The Energy Savings Formula?

The Energy Savings Formula calculates the financial savings achieved by reducing energy consumption, typically through efficiency improvements like window upgrades.

2. How Does The Calculator Work?

The calculator uses the Energy Savings Formula:

Where:

• \( E_{old} \) — Old energy consumption (kWh)
• \( E_{new} \) — New energy consumption (kWh)
• \( C \) — Cost per kWh ($/kWh)

Explanation: The formula calculates the difference between old and new energy usage, then multiplies by the cost per unit to determine monetary savings.

3. Importance Of Energy Savings Calculation

Details: Calculating energy savings helps quantify the financial benefits of efficiency upgrades, informs investment decisions, and demonstrates environmental impact reduction.

4. Using The Calculator

Tips: Enter old and new energy consumption in kWh, and cost per kWh in dollars. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What types of energy savings can this calculate?
A: This calculator works for any energy efficiency improvement where you can measure before and after consumption, particularly window upgrades.

Q2: How accurate are these savings calculations?
A: Accuracy depends on the precision of your input data. For best results, use measured energy data rather than estimates.

Q3: Should I use average or time-of-use electricity rates?
A: For most accurate results, use the actual rate you pay. If you have time-of-use pricing, consider calculating savings for each rate period separately.

Q4: Does this account for seasonal variations?
A: No, this is a simple calculation. For comprehensive analysis, compare energy use during similar weather conditions or calculate annual savings.

Q5: Can this calculate payback period for efficiency upgrades?
A: While this calculates savings, you would divide upgrade cost by annual savings to determine simple payback period.
