|
Background |
AHFC’s BEES (Building Energy Efficiency Standard) is based on the 2018 IECC and adapted for Alaska’s extreme climate. |
|
State-Owned/Funded Buildings |
All state-financed residential buildings must comply with AHFC BEES. |
|
Adoption Process |
Code adoption is implemented through AHFC programs and local enforcement. |
|
Enforcement Process |
Compliance is verified through energy audits, inspections, and blower door tests. |
|
Compliance Process |
Homeowners must submit ResCheck reports or verified home energy ratings to qualify for AHFC loans and rebates. |
Why AHFC BEES Matters for Homeowners and Builders
• Lower Energy Bills: Compliance with BEES results in significantly lower heating and energy costs.
• Enhanced Comfort: Improved insulation and airtightness reduce drafts and temperature fluctuations.
• Higher Home Value: Energy-efficient homes have a higher resale value and qualify for special financing.
• Environmental Impact: Reduced energy consumption helps lower carbon footprints.
How to Achieve Compliance
1. Design Phase:
• Ensure the building meets AHFC BEES insulation, air sealing, and HVAC standards.
• Use energy modeling software (ResCheck) to verify compliance.
2. Construction Phase:
• Follow AHFC standards for air sealing, ductwork, and insulation.
• Schedule third-party inspections to verify compliance.
3. Final Testing & Certification:
• Conduct a blower door test to confirm airtightness (≤3 ACH50).
• Obtain a verified home energy rating for AHFC certification.
4. Submit Documentation:
• Provide compliance reports (ResCheck, energy rating certification) to AHFC or the local jurisdiction.
Final Thoughts
The Alaska AHFC Residential Energy Code 2018 ensures that homes in one of the coldest climates in the world meet high efficiency standards. By complying with BEES, homeowners and builders can reduce heating costs, improve indoor comfort, and increase property value while contributing to a more sustainable energy future.
