Project Title CNCC Craig Campus Geothermal Program: 82-well closed loop GHP well field to provide geothermal energy as a common utility for a new community college campus.
Project Type / Topic 1 Recovery Act – Geothermal Technologies Program: Ground Source Heat Pumps
Project Type / Topic 2 Topic Area 1: Technology Demonstration Projects

Project Description This "geothermal central plant" concept will provide ground source loop energy as a utility to be shared by the academic and residential buildings on the soon-to-be-constructed campus.

The primary component in this campus approach is the common GHP well field ground heat exchanger (GHEX). The innovative design of the shared well field will demonstrate that it is cost-effective to develop shared geoexchange systems to provide GHP energy for present and future growth on campus. Each new building will be constructed with individual GHP mechanical systems and will utilize the common GHP loop energy.

In addition to grants, the project will also be funded in-part from energy savings performance contracting. The demonstrated energy savings will be guaranteed by an energy services company (Chevron Energy Solutions) and the associated utility and operational savings will be leveraged to help fund the total cost of the project.

As well as providing energy savings benefits, this project is expected to create 65 “green” jobs.

Funding Opportunity Announcement DE-FOA-0000116

DOE Funding Level (total award amount) $430,000.00
Awardee Cost Share $516,149.00
Total Project Cost $946,149.00



Principal Investigator(s) Dr. John C. Boyd, President, CNCC


Targets / Milestones Geothermal energy provided by a ground source heat pump system will reduce consumption of electricity (~60% is from coal) and natural gas resources compared to traditional heating and cooling systems. This project will reduce CO2 emissions by 539 Tons per year compared with a traditional HVAC system. A 25-year Lifecycle Cost Comparison (LCC) demonstrates the economic viability of the GHP technology with traditional HVAC construction. The results of this analysis which takes into account initial capital cost estimates and energy models using a Trace 700 model shows that the GHP solution is the most economic solution for the new campus. This project will demonstrate and report on the actual implemented costs and energy usage.
