The new Environmental Science and Chemistry building (ESCB) will be home to the Department of Physical and Environmental Sciences and will house two of the three disciplines (Chemistry and Environmental Science). There is a geothermal field installed below the building foundations designed for a portion of 40% of the building cooling load. The geothermal field was designed to maximize capacity within the available footprint of the building foundations. Between 75 and 80 vertical boreholes (450 feet deep) were installed which provides in the order-of- magnitude of 200 tons of cooling rejection. . The use of Earth Tubes, a geothermal system, magnetic bearing chillers, and a low temperature (ultra high efficiency) heating water system contributes to an energy efficient and sustainable building.
