Article Title and/or Image Caption (Dublin Core): Title: World's largest building cooled by sun control
extracted text (Extract Text): THE sun cools, as it heats, the Army's

Pentagon Building in Arlington, Va,
(P.S.M., Feb, '43, p. 49). Passing over the
vast roof of the world's largest building, its
rays fall upon photoelectric cells in five
roof-top control stations. Registering the
temperature rise, each of these stations in
turn, by means of electronic relays and
compression tanks, activates the fans of
the cooling system. Designed by the Min-
neapolis-Honeywell Regulator Company
and Charles S. Leopold, consulting engi-
neer of the War Department, the system
maintains a temperature of 77 degrees.
