Home Energy Labels reveal the energy performance of a home and the energy efficient assets in a home independent from occupant behavior. For existing homes, labels typically include a list of recommended upgrades to improve comfort and reduce energy bills. For new homes, labels highlight advanced energy measures that push toward net-zero energy where homes produce as much as they consume. These labels can be made publicly available to homebuyers to better understand the costs of homeownership. Home energy labeling creates economic development, clarifies energy cost burdens for residents and reduces energy use by providing a pathway for homeowners to identify and access special financing to make energy savings improvements.

Use EPS to Find a Home That’s Built to Perform

Brought to you by Energy Trust of Oregon, EPS is an energy performance score that helps smart homebuyers find homes that offer superior efficiency, comfort and savings. EPS lets you look behind the walls to see the true energy impact of a home. It reveals the estimated energy costs, the environmental impact, and it highlights specific energy-efficient features.

To earn a score, homes are third-party tested to be at least 10 percent above code with energy-saving solutions such as high-performance insulation, tight construction and efficient heating and cooling. EPS is compatible with other widely recognized energy ratings, and stands as a true symbol of top-quality construction.

Enerstructa is a third-party verifier for EPS homes in the Columbia River Gorge. EPS is similar to a Home Energy Score but includes a deeper analysis of a home's energy consumption, utility costs and carbon footprint through energy modeling. As part of EPS, we perform blower door testing which measures air tightness. We also test duct systems to ensure they are well sealed and insulated. We work with contractors throughout the design and construction process to support new cost effective ways to increase efficiency and durability in the homes they build. Contractors receive utility funded incentives for increased performance based energy efficiency measures.

We are a certified Sustainable Homes Professional, Home Energy Assessor, HERS Rater, BPI Building Analyst and Envelope Professional, and an Energy Trust of Oregon Trade Ally Contractor.

Resilient homes are affordable, durable, comfortable, healthy and energy efficient. They reduce the cost of homeownership through built in energy and water consumption savings. They include sustainable building materials that contribute to better indoor air quality. They are performance tested for air tightness and mechanical ventilation which ensures long term comfort and durability.

Earth Advantage certified homes reward you and your family with the quality of a home that reflects your lifestyle choices. All certified homes comply with prerequisites that assure construction best practices are implemented. The number of additional elective measures determine the certification level of each home; Silver, Gold, Platinum, or Zero Energy. Third-party certification ensures five key areas of building a sustainable home are met: energy, health, land, materials, and water.
