Warren Woods Ecological Field Station
The University of Chicago’s two-story, 2,450-sf Warren Woods Ecological Field Station is the first Passive House-certified laboratory in North America and only the fifth in the world. “Passive House” standards achieve minimal energy usage for heating and cooling, despite the presence of a minus-80-degree-Celsius freezer, plant growth chambers, an incubator, and tools for DNA extraction, all of which generate a lot of heat, coupled with a humid environment and a high level of occupancy by researchers.
