The Milam Building was the tallest reinforced-concrete structure and the first air conditioned high-rise office building in the world. Carrier offered this building the first-of-a-kind air conditioning equipment by allowing doors and windows to be closed, reducing dirt and noise from the street. “Buffalo” units were installed in 1928. Several of the units were refurbished during the renovations made between 1989 and 1994.
