The Federal Trade Commission announced February 22 that proposed settlements in five separate cases will prohibit replacement window sellers from making exaggerated and unsupported claims about the energy efficiency and energy cost savings of their windows. Though many electronic devices carry energy guide labels that indicate measured energy savings, windows do not display efficiency qualifications. The proposed settlement would required companies to possess and rely on scientific evidence before making energy efficiency and cost savings marketing claims and requires each company to substantiate savings claims that include the words “up to” a certain amount of money or achieve energy savings “up to” a certain amount.
