The rebirth of a touierng icon: Empire State Building becomes model of energy efficiency

摘要

Soaring above the corner of Fifth Avenue and 34th Street in the heart of Manhattan, the Empire State Building is truly an American icon. Dubbed "the world's most famous office building" and "a prewar trophy," it has been featured in more than 250 films and is one of New York City's most popular and enduring tourist attractions.rnTo engineers, though, the Empire State Building is more than just a celebrated skyscraper: It is also 'a district energy system standing on its head,' with its own large central cooling plant below street level and piping networks supplying chilled water as well as district steam from Con Edison to individually monitored tenants on the 102 floors above.
