How We Analyze Home Energy
Based on DOE Data
We utilize the latest consumption profiles from the U.S. Department of Energy (EIA) specific to your state's climate zone and average utility rates.
Home-Specific Modeling
Your home's vintage (year built) and square footage determine its "Thermal Leakage" factor, which drastically impacts heating/cooling costs.
Frequently Asked Questions
Is this calculator accurate for my specific city?
While we use state-level averages for rates, our consumption model adjusts for your specific home size and age. For exact localized rates (e.g., Houston vs. Dallas), the tool uses a weighted average for your state.
Why don't you ask for my utility login?
Privacy is our priority. Many tools scrape your data to sell leads. ZunoEnergy is designed to give you a "Smart Estimate" instantly without needing invasive access to your private accounts.
What does the "Health Score" mean?
Your Home Energy Health Score (0-100) is a benchmark against efficient, modern construction. A score of 100 means your home performs like a net-zero 2024 new build. A score below 50 indicates significant waste from older insulation or HVAC.
