The office expansion for Miron Construction’s Neenah, Wisconsin headquarters was completed in 2009. Tweet/Garot was selected as the HVAC contractor of choice. The project consisted of two new wings to the existing office adding an additional 51,000 square feet.

A unique aspect of this project is that it has a geothermal heating and cooling system. The geothermal field is under one of the parking lots and is a vertical design.

Tweet/Garot did not install the geothermal field, but did connect to the field and installed all the HVAC piping and related heating/cooling equipment. There are a total of 42 heat pumps installed throughout the new addition. The geothermal system has proven to be very efficient. It is estimated that 40-50% of energy savings are being realized due to the efficient design and application.
