HERS-Rated for Energy Efficiency
Designing for Energy Efficient Performance Starts on Day One
Many homeowners don’t learn about the HERS (Home Energy Rating System) requirement until it’s too late—when construction is nearly complete and design decisions have already locked in inefficiencies. At Beauchemin Designs, we take a proactive approach. By integrating HERS standards from the very beginning, we design homes that are not only beautiful but also energy-efficient and compliant with state regulations.
With our sister company, Energy Geeks, we’ve seen firsthand how costly it can be to overlook these performance standards. Our process ensures that your new home meets or exceeds energy code requirements—without last-minute stress or expensive fixes.
Better design. Smarter planning. Lower HERS scores.
Accessibility Within a High-Performance Framework
Aging In Place Home Modifications
Aging in place requires more than adding grab bars or widening doorways. In New England, accessibility must be integrated into the home’s structure, mechanical systems, and building envelope to ensure long-term comfort and durability
Beauchemin Designs approaches aging-in-place renovations through a systems-based, climate-aware framework — aligning universal design with energy performance, moisture control, and structural planning. The result is a home that supports independence while continuing to perform efficiently for decades to come.
