Energy Star Certification

Homes that earn the ENERGY STAR are at least 15% more energy efficient than standard homes. That means lower energy bills for you, and a reduced impact on the environment. ENERGY STAR home builders achieve this high efficiency for you by selecting from a variety of features:

EFFECTIVE INSULATION - Ensures even temperatures throughout the house, while using less energy.
HIGH-PERFORMANCE WINDOWS - Keep heat in during winter and out during summer.
TIGHT CONSTRUCTION AND TIGHT DUCTS - Improve comfort and indoor air quality, while lowering utility and maintenance costs.
MORE EFFICIENT HEATING AND COOLING EQUIPMENT - Uses less energy, which reduces utility bills.
INDEPENDENT TESTING - While it's easy to claim that homes are energy efficient, ENERGY STAR partners back the claim up with a third-party inspection verifying the energy performance of your home.

Xcel Energy's Home Efficiency Program helps home builders construct ENERGY STAR homes by providing training, construction site inspections and third-party testing for ENERGY STAR certification.
