About this calculator
The Efficiency Gap calculator measures the difference between a system's current energy performance and its theoretical potential. It calculates (Current - Potential) / Current, resulting in a value representing unused efficiency as a percentage or fraction. Useful for evaluating waste in plants, buildings, or industrial processes.
To use it, input real consumption data and the theoretical maximum. Negative results show underperformance (e.g., -0.2 = 20% loss). Positive values indicate exceeding expectations. Common in energy efficiency analysis, it helps prioritize investments in improvements.
Important: Input data must be consistent (same unit, e.g., kWh/month). This tool doesn't replace technical audits but provides a quick overview of optimization opportunities. Avoid comparing distinct systems without adjusting variables like scale or environmental conditions.
Frequently asked questions
What does the calculator measure?
It calculates the difference between current energy performance and theoretical potential, showing unused efficiency as a percentage or decimal.
How to interpret a negative result?
A negative value (-0.2, for example) means current performance is 20% below theoretical potential, indicating room for improvement.
What are the results used for?
Identifying waste reduction opportunities in energy systems and prioritizing improvements in plants, buildings, or industrial processes.
Can I use different units?
No. 'Current' and 'Potential' values must use the same unit (kWh, MJ, etc.) to ensure accuracy.
What if the result is positive?
It means performance exceeds theoretical potential, which is uncommon. Review data or consult experts to confirm.
