We recently talked to the team in the Dallas market, and they told us, “At Mattamy Homes, sustainability is one of our core values. We go beyond code requirements to make sure our homes are both affordable and energy-efficient. We invest in keeping detailed records and performance data so we can better understand how our homes are performing and identify opportunities to keep improving. Rating every home helps us stay consistent, transparent, and focused on delivering lasting value to our homeowners.” As for marketing their homes, “We display expected HERS scores on our website by plan and community. Each of our sales counselors is equipped with tools and training to discuss estimated HERS scores and explain what they mean for our buyers. We also highlight that every home we build is expected to receive a rating as part of our standard features.” More and more buyers are seeing the value of a HERS rating, especially when comparing home options. It gives them confidence that they’re buying a well-built, efficient home. For many, it’s another layer of assurance that their builder has invested in their long-term comfort and savings The team concludes, “We work with US-EcoLogic, and they’ve been a great partner in helping us meet and exceed our energy efficiency goals. Their third-party testing, feedback, and code expertise help us improve our construction practices, keep our HERS scores low, and choose the best ways to meet or go beyond code requirements.
