Case Studies – Temporary Climate Solutions

Bill Gates Foundation World Headquarters - Iris Campus

With very little space in the yard and no space on the curbs outside to place equipment, logistical creativity was a must for the two large Iris Campus buildings of the Bill Gates Foundation World Headquarters.

The solution was to place large desiccant dehumidifiers on the roof and on the ground (hugged right up to the building and ducted vertically into the floors). For maintaining temperatures in a season that went below freezing on several occasions, Polygon built small hot water heaters to be placed on each floor. This system used the building’s closed-looped hot water system to heat the building while drying it with desiccants.
