Frequently Asked Questions
A HERS (Home Energy Rating System) rating is a standardized measurement of a home's energy efficiency. It's like a miles-per-gallon rating for a house, providing a clear indication of its energy performance. Lower HERS scores indicate better energy efficiency and lower utility bills. Custom Green Construction Inc. provides certified HERS ratings to help you optimize your project.
California's Title 24 energy code often requires HERS ratings for new construction and major renovations to ensure compliance with energy efficiency standards. A HERS rating can also qualify you for energy efficiency incentives and rebates, increasing your property value. Custom Green Construction Inc. can guide you through the requirements and benefits.
Custom Green Construction Inc. offers comprehensive HERS rating services, including plan review, on-site inspections, and performance testing. Our certified raters will work closely with you to identify opportunities for energy savings and ensure your project meets all applicable codes and standards, maximizing your investment and environmental impact.
