Energy Performance Score compares home energy consumption

The last time you bought a car, especially in the current economy, you probably paid close attention to the fuel efficiency by looking at the mile-per-gallon ratings and comparing similar vehicles. Now home buyers in certain states may soon be able to do the same with homes, and it looks like the trend will go national.

Earth Advantage Institute, a leading nonprofit green building resource that has certified more than 11,000 homes, has played a key role in the conceptualization, promotion, and adoption of the Energy Performance Score (EPS), currently the only residential energy labeling system that enables buyers to directly compare home energy consumption. The tool provides homeowners with both an energy consumption score and an associated carbon emission score. The number is based on in-home measurements and diagnostics data, as well as your utility’s energy source, which are entered into online software for calculation.

The EPS has proven popular enough in the Northwest that it has been rolled out on a voluntary basis for new homes in Oregon and in a large 5,000-home pilot for existing residences in Seattle. Both Oregon and Washington state legislatures have created task forces to explore the potential of mandatory energy labeling at time of listing. Lawmakers see energy labeling as a key tool in motivating homeowners to make energy efficiency improvements. Homeowner surveys indicate the public is heavily in favor of having a rating system that can help them obtain information on energy performance, where to make improvements, and how to add to the value of their home.

“We use EPS information as a marketing tool to help sell our homes,” said Aaron Fairchild, president of G2B Ventures, a Seattle-based real estate investment firm. “The EPS is an amazingly innovative tool that will help us transform the Seattle real estate market.”

Now the federal government has turned its eyes toward energy labeling. The Department of Energy has targeted the month of October as the deadline for developing a voluntary national rating standard that may serve as a tool for banks and other institutions to provide preferred finance products for energy efficient, healthy homes.

“We pointed to energy labeling as one of the top 10 green building trends for 2010,” said Sean Penrith, executive director, Earth Advantage Institute. “The federal government has taken up the flag, and has asked for additional data on the EPS program to inform its efforts in creating a voluntary standard this year.”

who we are:

Early in 2008, St. Petersburg College recognized its responsibility to model to our students, employees and community ways to minimize global warming emissions and provide the knowledge to our graduates to help achieve a more environmentally friendly future. Because of this, the College made sustainability (defined as meeting the needs of the present without compromising the ability of future generations to meet their own needs) a top priority. As a result, the Office for Sustainability was established.

what we do:

Working alongside internal and external partners, the Office for Sustainability focuses on the following areas of environmental stewardship: educational programs and corporate training, energy and natural resource conservation, green buildings and facilities, carbon emissions, recycling and student activities.
