【 摘 要 】

Colorado Northwestern Community College (CNCC) is working collaboratively with recipient vendor Chevron Energy Solutions, an energy services company (ESCO), to develop an innovative GHP project at the new CNCC Campus constructed in 2010/2011 in Craig, Colorado. The purpose of the CNCC Craig Campus Geothermal Program scope was to utilize an energy performance contracting approach to develop a geothermal system with a shared closed-loop field providing geothermal energy to each building's GHP mechanical system. Additional benefits to the project include promoting good jobs and clean energy while reducing operating costs for the college. The project has demonstrated that GHP technology is viable for new construction using the energy performance contracting model. The project also enabled the project team to evaluate several options to give the College a best value proposition for not only the initial design and construction costs but build high performance facilities that will save the College for many years to come. The design involved comparing the economic feasibility of GHP by comparing its cost to that of traditional HVAC systems via energy model, financial life cycle cost analysis of energy savings and capital cost, and finally by evaluating the compatibility of the mechanical design for GHP compared to traditional HVAC design. The project shows that GHP system design can be incorporated into the design of new commercial buildings if the design teams, architect, contractor, and owner coordinate carefully during the early phases of design. The public also benefits because the new CNCC campus is a center of education for the much of Northwestern Colorado, and students in K-12 programs (Science Spree 2010) through the CNCC two-year degree programs are already integrating geothermal and GHP technology. One of the greatest challenges met during this program was coordination of multiple engineering and development stakeholders. The leadership of Principle Investigator Pres. John Boyd of CNCC met this challenge by showing clear leadership in setting common goals and resolving conflicts early in the program.
