Requirements for HERS Rating Certification
A professional auditor must evaluate a building’s energy consumption to meet the HERS rating requirements. The HERS index score is based on a 0 – 150 scale, with 0 representing net-zero energy (the ideal).
Elements that are evaluated include:
Building Envelope
Insulation Quality & Installation: Checks that insulation is properly installed, without compression or gaps, and meets rated R-values.
Air Sealing: Identifies leaks around windows, doors, electrical outlets, and penetrations.
Thermal Bridging: Looks for areas where heat can bypass insulation.
Ductwork & HVAC System
Duct Leakage Testing: Uses a duct blaster to measure air leakage in the duct system.
HVAC Equipment Efficiency: Verifies the system’s SEER, EER, HSPF, and AFUE ratings.
Proper Ventilation & Airflow: Ensures adequate airflow to maintain indoor air quality and comfort.
Blower Door Test
Measures air leakage in the home to determine airtightness and compliance with energy codes.
Windows & Doors
Checks U-factor and SHGC (Solar Heat Gain Coefficient) to confirm compliance with energy efficiency requirements.
Water Heating System
Evaluates the efficiency of water heaters and distribution systems.
Inspects for proper insulation on hot water pipes.
Lighting & Appliances
Reviews energy-efficient lighting (LEDs, CFLs) and ENERGY STAR-rated appliances.
Renewable Energy (if applicable)
Inspects solar PV systems, battery storage, or other renewable energy components.
Why Pursue HERS Rating Certification?
Achieving HERS certification offers a multitude of benefits, particularly for large-scale, multi-family housing projects. These benefits include:
- Reduced Operational Costs: Lower energy consumption translates directly to significant savings on utility bills over the building’s lifespan.
- Enhanced Building Value: A certified energy-efficient building is more attractive to tenants and buyers, increasing its market value.
- Improved Occupant Comfort: Buildings designed for optimal energy performance often result in more consistent temperatures and better indoor air quality.
- Compliance with Energy Codes and Standards: HERS ratings can help projects meet or exceed increasingly stringent energy codes and sustainability goals.
- Demonstrated Commitment to Sustainability: Achieving a favorable HERS rating showcases your organization’s commitment to environmental responsibility.
