The project consisted of energy retrofits and renovations to the existing Headquarters/Visitor Center. The existing concrete floor slab within the facility were removed to allow for updated plumbing and new code compliant restrooms. The new building addition will also house a new conference room, break room, additional offices, and storage.
MEP recommended the use of a geothermal HVAC system to provide heating and cooling through individual heat pumps with zoned temperature control. Water-to-air heat pumps located in the mechanical rooms will either extract or reject heat to the geothermal ground loop as needed to heat or cool the building. With the use of water-to-air heat pumps, each zone can control their desired temperature with a 24/7 programmable wall mounted thermostat.
Dedicated make-up air systems with energy recovery wheels will provide the required outside air CFM to each heat pump unit. Water-to-water heat pumps connected to the geothermal system will provide hot water in-floor heating along the building perimeter for improved comfort.
