Answer 20 questions about your home. Get a 1-10 efficiency score and prioritized upgrade list. All data stays in your browser.
This calculator asks 20 questions about your home and gives you a score from 1 to 10. A 1 is a drafty shack. A 10 is net-zero ready. Most homes score 4 to 6.
The questions cover insulation, air sealing, HVAC age, thermostat type, appliances, lighting, and solar. Based on your answers, the calculator generates a prioritized upgrade list with estimated cost, payback period, and annual savings for each improvement.
Tip: Do the cheap fixes first. Air sealing ($50) and a smart thermostat ($200) often pay back in under 6 months. Save insulation and windows for later.
