In the market for a new home in Oregon? You can now check the energy efficiency of a house before you buy using the Earth Advantage Institute’s Energy Performance Score (EPS), developed in conjunction with Energy Trust of Oregon.
According to Earth911, the EPS system uses a 32 point audit that analyzes the energy efficiency of participating homes in terms of their energy usage and carbon emissions based on the electricity and natural gas consumed, as well as insulation, appliances and regional weather. These numbers are then compared with the state average, offering home buyers a relative “miles per gallon” type of analysis for new homes they may be considering, as well as potential upgrades for how to improve the score.
This Energy Performance Score system is already in use on a voluntary basis for new homes in Oregon and for existing homes in a city of Seattle pilot program; it is also currently being considered in other cities, including Chicago and Houston.
