We verify: HERS Index target per ENERGY STAR v3.1 (National + Regional), thermal enclosure checklist (air sealing + insulation), HVAC completion checklist, water management system (per ENERGY STAR Water Management System Certification), and lighting/appliance packages.
v3.1 adds National + Regional HERS Index targets, a thermal enclosure checklist with separate thermal / air-sealing sections, more stringent water management requirements, and a program-affiliated HVAC checklist. v3.0 projects in Missouri are no longer accepted for new certifications as of 2025.
HECS documents the specific failure (HERS Index above target, missing checklist item, water-management gap) and recommends corrective action. Re-inspection is coordinated at no charge for the first re-visit within 30 days. The certification only ships once all requirements pass.
