Iris Campus - Bill Gates Foundation World Headquarters

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.

Kaiser Permanente Hospital

Polygon and the Contractor utilized a sheet metal ducting and stack system to deliver dehumidified air onto each floor of the Kaiser Permanente Hospital. Polygon was able to save the building owner 194 KW in power consumption (roughly $22,410 per month). The system worked so well, that even though it had been slated to be used for seven months, the Contractor did not need it for the entire contract length.

Yale University Art Gallery

Yale University Art Gallery’s $135 million restoration and expansion project included the full renovation of two historic structures — the 1928 Gothic-style Swartwout building and the 1866 Street Hall. Their careful conversion enlarged exhibition spaces, collection study rooms and classroom facilities. Polygon was brought in to provide both temperature and humidity control for the preservation and renovation of extensive millwork. These finished wood products had to be installed and kept within the Standard Service Life Conditions. Polygon’s HCU dehumidifier cooled and dehumidified the gallery to the specified humidity levels and saved more than $10,000 a month in energy costs.
