How the Smart Energy Checkup Works
Our methodology combines U.S. Department of Energy data, EIA state rate averages, and realistic efficiency improvements from Energy Star and LBNL studies. Each recommendation’s potential savings is computed based on your home type, size, and state climate.
- ZIP Validation: Fetches state and region for accurate rate and weather assumptions.
- Baseline Estimate: Annualized using your bill or state-level averages.
- Home Factors: Adjusted for size, age, and common inefficiencies.
- Smart Moves: Each selected improvement applies an empirical savings range (5–25%).
- CO₂ Calculation: Derived from regional emission intensity (EPA 2024 data).
Note: The calculator gives practical, educational insights — not utility-grade measurement. Actual savings vary by behavior and equipment condition.

Why Filters Matter
Dirty filters make HVAC systems work 10–15% harder. Replace or clean them monthly during heavy-use seasons for immediate ROI.
Insulation: The Silent Saver
Attic insulation pays for itself in 3–5 years. A properly sealed attic can save 15–25% of heating and cooling costs annually.
Smart Thermostats
Learning thermostats like the Amazon Smart Thermostat can cut cooling costs by up to 20% — and qualify for rebates in most states.
LEDs and Dimmers
LED bulbs use 75% less energy and last 25× longer than incandescents. Add dimmers for ambiance and extra savings.
Fans and Airflow
Using ceiling fans lets you raise your thermostat 2–4°F without losing comfort — a 10% cooling bill cut instantly.
Behavioral Tweaks
Turning off lights, managing peak hours, and optimizing schedules can save $100–$200 annually — zero investment required.

Frequently Asked Questions
How accurate is the Smart Energy Checkup?
Estimates are based on U.S. Energy Information Administration data, state-level rates, and DOE modeling. Expect around ±10% variance depending on equipment and weather.
Is my data stored or shared?
No — all calculations happen locally in your browser. ZIP and usage info are not saved. Email is optional and logged privately for follow-up only.
Does this replace a home audit?
Not exactly — think of it as a digital pre-check. It gives you clarity before hiring a professional audit or investing in new appliances.
Which states work best with the calculator?
The Checkup is optimized for all 50 states. It’s most accurate in high-load states like Texas, Florida, California, Illinois, and New York.
