Geothermal Heat Pump Retrofit Project at 1315 Airport Boulevard
Document Type
NOE - Notice of Exemption

Document Description
The project components at the 1315 Airport Boulevard building would include 1) the installation of underground geothermal vertical piping loops using boreholes, within the existing parking lot, for connection to geothermal heat pumps that would use water to deploy geo thermal heat technology; 2) piping and geothermal heat pumps within the suspended ceiling space of the building; 3) water circulation pumps and a pump enclosure on the north side of the building; and 4) modifications to the existing heating, ventilation, and air conditioning (HVAC) system to utilize the geo-exchange technology. Minor trenching would be needed to run piping between the boreholes, into and out of distribution boxed, and into the building's HVAC system.
