SUSTAINABILITY

Energy Star Certified
90
ENERGY STAR certified buildings save energy and help protect the environment.

SUSTAINABILITY

ENERGY STAR® Energy Star is a program run by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE) that promotes energy efficiency and provides simple, credible, and unbiased information that consumers and businesses rely on to make well-informed decisions. Thousands of industrial, commercial, utility, state, and local organizations partner with the EPA to deliver cost-saving energy efficiency solutions that protect the climate while improving air quality and protecting public health. The Energy Star score compares a building’s energy performance to similar buildings nationwide and accounts for differences in operating conditions, regional weather data, and other important considerations. Certification is given on an annual basis, so a building must maintain its high performance to be certified year to year. To be eligible for Energy Star certification, a building must earn a score of 75 or higher on EPA’s 1 – 100 scale, indicating that it performs better than at least 75 percent of similar buildings nationwide. This 1 – 100 Energy Star score is based on the actual, measured energy use of a building and is calculated within EPA’s Energy Star Portfolio Manager tool.
