What is Energy Star?

An Energy Star New Home means it was designed and built to standards well above most other homes on the market today. Energy Star new homes are built with rigorous requirements that result in better durability, better comfort, and reduced utility and maintenance costs. Even in states with more stringent energy codes, the U.S. Environmental Protection Agency ensures that Energy Star remains the symbol for truly energy-efficient performance. Energy Star homes are designed with integrated systems and features to deliver higher performance energy efficiency.

  1. High-Efficiency Heating & Cooling: Equipment and systems that use less energy, operate at reduced noise levels, and come with extended warranty coverage. Providing better moisture control and improved indoor air quality to your home.

  2. Complete Thermal Enclosure System: Using air sealing, proper insulation, and high-performance windows to enhance comfort, improve durability, reduce maintenance costs, and lower monthly utility bills.

  3. Efficient Lighting and Appliances: Energy Star certified appliances and lighting provide high-quality performance while also reducing energy costs.

  4. Water Protection System: Comprehensive building practices and materials protect roofs, walls, and foundations from water damage and helps ensure durability and prevent moisture-related indoor air quality problems.

Benefits for Homeowners


  1. Peace of Mind: Tried-and-true best building practices followed by independent inspections and testing from certified professionals mean that you can be confident that things were done right

  2. Enduring Quality: Value-adding energy efficiency features and a combination of materials and equipment deliver better performance and an overall superior level of quality

  3. Wall-to-Wall Comfort: You’ll see, feel, and hear the difference of a heating and cooling system that has been engineered and installed to efficiently deliver comfort. Enjoy consistent temperatures across every room and a constant supply of fresh, filtered air reducing indoor pollutants, dust, pollen, and other allergens.

  4. Proven Value: Better energy efficiency and performance means lower utility and maintenance costs. Homes earning the ENERGY STAR label use 15-30 percent less energy than typical new homes, and even more when compared to most resale homes on the market today.
