Milwaukee St. John Mariner Bldg -1937 AD

First office building in Milwaukee to have year round “air conditioning” with windows that could not be opened by tenants. When I worked there in the 1970s the old York “ice” machine was still in the basement, however a new chiller had been installed because the old one was not fully automatic.

Another interesting part of the cooling was the roof had a sprinkler system and “high” drain covers that would allow for flooding of the roof on hot days to “reflect the heat of the sun and to keep the roof cool with water.

This building is now the Hotel Metro and was designed by Eschweiler & Eschweiler – at one time all of the great Art Moderne features of the interior could be seen. I am certain that the renovation of the building eradicated most of it.
