In the past, many mechanical cooling systems designed to reduce energy costs and demand were innovative but cost-prohibitive for most applications. Now, however, alternative energy solutions with relatively quick paybacks have been developed. One such solution is thermal energy storage, which is growing in use and reducing electrical costs around the country.
TES systems work well for facilities ranging from as few as 100,000 sq ft to those with up to several million sq ft of space. They work best in facilities that are not fully operational at night, such as office buildings, schools, airport terminals, convention centers, and sports complexes.
