* Estimate, not measured. EULs are sourced (see Methodology).
Reported, not scored: ~445 therms/yr gross avoided · ~2.36 t CO₂/yr (EPA factor).
Peak-day use 5.5 therms (estimated from size and insulation); annual use 832 therms (estimated from size, insulation and age).
Rough screening estimate using rule-of-thumb factors — not an energy audit.
