Liberty School District

Liberty Schools J-4 is a small, rural public school district serving the communities of Kirk and Joes in the Eastern Plains of Colorado. With a focus on educational excellence, the District is proud to have a 100% graduation rate for over two decades and has received Accreditation with Distinction from the ColoradoDepartment of Education for five consecutive years.

For many years, the District has dealt with a failing steam heating system, inefficient and ineffective cooling from window A/C units, and no ventilation system of any kind. During the development process, the Millig team identified aunique opportunity to address the heating, cooling, and ventilation needs notonly at the K12 School but also the central plant building. These two facilities nowshare one highly efficient thermal energy network provided by a ground-sourceVariable Refrigerant Flow (VRF) system. This system combined with a dedicatedventilation system, fed by Energy Recovery Ventilators (ERV), provide much-needed cooling and ventilation functions, both lacking previously, whilemaintaining the operating costs previously experienced by the District.

To offset significant project costs associated with ground loop installation and the highly efficient electric heat pumps, the Millig team assisted District administration in applying for and securing several external funding sources.

Scope:

• Ground-Source Variable Refrigerant Flow (Thermal Energy Network)

• Energy Recovery Ventilation System

• Packaged Rooftop Unit (Gymnasium)

• New Electrical Infrastructure

• Modern Code Compliant Fire Alarm System
