The last of the GI.4 Heat Exchangers were installed last week. Work will begin soon on the horizontal connections between the bores and will eventually be connected to the buildings in the geo-district. While the bore headers currently appear above grade, the entire field will eventually be beneath the frost line in order to prevent freezing.
The diagram below shows an overview of the field. The field will only serve buildings 1-3 for now. Once Phase I of the Yale Acres project is completed and energy savings in the Energy Star building is verified, the remaining buildings will be upgraded and the field will eventually serve buildings 1-4.
