One of the original West Building refrigerating compressors, 1941
The West Building was planned and constructed with the most modern
mechanical systems available at the time. It was among the first museums in the world to include air
conditioning as an integral part of the design. Elaborate equipment provided a continuous flow of air
to manage temperature and humidity throughout the building. Though now modernized, the system was so
effective that it was extended to the East Building and remains in use today.
