Search Built to Save® Certified Homes in the Rio Grande Valley
Every home in this database passed two independent inspections — once before drywall and once at final completion — conducted by a RESNET-certified home energy rater. Built to Save® certification requires a HERS score of 63 or lower, which means these homes use significantly less energy than a home built to minimum Texas code. That score is not self-reported. A third party measures it.
What the database shows you: all Built to Save® certified homes in the Rio Grande Valley, verified by Magic Valley Electric Cooperative (MVEC) and RESNET. Search by street address or certificate number to confirm a specific home’s certification status before you buy.
Why this matters before you sign a contract: builders across the RGV use terms like “energy efficient,” “green,” and “high performance” in their marketing. Built to Save® certification is the only Rio Grande Valley standard backed by independent, third-party verification. If a home is not in this database, it has not been certified — regardless of what the sales brochure says.
Frequently Asked Questions
What is the Built to Save® certified homes database?
The database lists every new home in the Rio Grande Valley that has earned Built to Save® certification. Each listing confirms that a RESNET-certified rater independently verified the home’s HERS score at 63 or lower — before drywall and again at final inspection.
How do I search for certified homes in a specific city?
Enter the street address or certificate number in the search tool above. To browse by city, use the city links below the search box. Each city page lists active certified builders and current communities.
What does it mean if a home is not in the database?
It means the home has not earned Built to Save® certification. A builder may market a home as energy efficient without independent verification. Only homes that appear in this database have been third-party verified to the HERS ≤63 standard.
How often is the database updated?
The database updates as homes complete certification. New certifications appear once the RESNET-certified rater files the final inspection and MVEC confirms the record.
Can I search by builder name?
Search by address or certificate number. To find homes by builder, visit the directory or browse the city pages for builder listings in your target area.
