An existing Goodwill building was completely renovated to consolidate and house the Douglas County Juvenile Assessment Center, Health Department, General Assistance, and Veteran’s Administration functions of the County. The new space provides the County with a central location, the ability to share resources, and a better working environment for the staff and operations.
The Design Team started by performing a comprehensive facility assessment and equipment inventory of the existing space. The assessment looked at code compliance, condition, capacity, energy usage, remaining life of HVAC equipment, and replacement cost. The Owner and Design Team worked together to determine what systems to salvage and re-purpose and what systems to replace. Ultimately, and the Owner chose to replace the HVAC system with a ground source geothermal solution.
The new ground source, closed-loop geothermal system consists of 105 wells at a depth of 250 ft each. Redundant variable speed central pumps support the system and deliver water to approximately 40 high efficiency water source heat pumps and 2 makeup air heat pumps with energy recovery. Heat pumps were carefully chosen and specified to maximize energy performance while allowing for a competitive bid as required by the County.
