The old Boston Floating Hospital (and, by old, we mean it ceased watery operations in 1927) was the first hospital in the U.S. to have air-conditioning (starting in 1906, wards were kept at a cool 70 degrees). By our back-of-the-envelop calculations that would make it the first "building" in Boston to have AC. Are we wrong? Stay cool. [Curbed Boston]
