This assessment estimates that energy loss through windows is approximately 15 percent of all the energy used for space heating and cooling in residential and commercial buildings in New York State. The rule of thumb for the nation as a whole is about 25 percent. The difference may reflect a traditional assumption of single-pane windows while this assessment analyzed installed window types in the region. Based on the often-quoted assumption, in the United States some 3.5 quadrillion British thermal units (Btu) of primary energy, costing some $20 billion, is annually consumed as a result of energy lost through windows. According to this assessment, in New York State, the energy lost due to heat loss through windows is approximately 80 trillion Btu at an annual cost of approximately $1 billion
