# RIBBON CUT ON ENERGY-EFFICIENT AND EARTH-FRIENDLY GEOTHERMAL HVAC SYSTEM - Link: https://greenlivingguy.com/2017/09/ribbon-cut-on-energy-efficient-and-earth-friendly-geothermal-hvac-system/ - Published: 2017-09-14T04:58:24-04:00 - Author: greenlivingguy MONROE, Mich. – Monroe County Community College officials formally recognized the college’s switchover. That’s from an outdated, conventional heating, ventilation and air conditioning system. That’s to a much more energy-efficient and earth-friendly geothermal-based system. All during a ribbon cutting ceremony today. # Geothermal The geothermal-based system will result in significant energy cost savings for MCCC. For it has a 50-year lifespan on its well field. One that is double that of a conventional system. Moreover it will greatly reduce the college’s carbon footprint. _Ameresco, Inc., a leading energy efficiency and renewable energy services provider. It was the engineer and general contractor for the project._ ## Five Main Campus buildings So the Audrey M. Warrick Student Services / Administration Building. Also the Life Sciences Building and Campbell Learning Resources Center. Finally the East and West Technology Buildings. All which were all built in the late 1960s or early 1970s. For they are now being served by the new MCCC geothermal-based system.

Geothermal-based HVAC brings the buildings into harmony with the earth beneath by taking advantage of subterranean temperatures to provide heating in colder-weather months and cooling in warmer-weather months, said Jack Burns, director of campus planning and facilities at MCCC, who oversaw the project. Outdoor temperatures fluctuate with the changing seasons; however, underground temperatures do not change as dramatically because of the insulating properties of the earth, he said.

All to capitalize on these constant temperatures to provide “free” energy to the buildings. “Essentially, we are using water that has been heated or cooled by the earth’s energy to a temperature that requires less additional energy to heat or cool it to acquire specific comfort levels, depending on the season,” Burns said.

The rectangular field sits on a 3-acre piece of land that is located on the extreme southeast portion of MCCC’s Main Campus. MCCC’s system is a closed-loop system that does not pump any ground water in or out, Burns said; rather, it was supplied by 10,000 gallons of water that were pumped in from the college’s connection to the city water system. Through its contract with Ameresco, the college is guaranteed to reduce its previous yearly energy consumption by about 160,000 kilowatt hours annually. ### It is guaranteed to save in total around $5.55 million in electricity, gas and water costs over the next 20 years or an average of $275,000 per year. But the system will likely save far more than that, according to Suzanne Wetzel, MCCC’s vice president of administration. “We fully anticipate that our energy savings will surpass the $5.55 million over 20 years that Ameresco has guaranteed,” she said. In addition to the cost savings of the geothermal system and its long life-cycle. For it provides substantial environmental benefits. According to Ameresco, MCCC will reduce its carbon emissions by 1,068 metric tons per year. Based on the Environmental Protection Agency’s Greenhouse Gas Equivalencies Calculator. So the annual green benefit from this reduction each year is equal to the following.. #### _**2.6 million road miles driven by an average passenger vehicle**_ _**120,176 gallons of gasoline consumed**_ _**1.14 million pounds of coal burned**_ _**113 homes’ energy use for one year**_ _**27,678 tree seedlings grown**_ #### _**1,011 acres of U.S. forests**_ _“This was an investment in the present and future of MCCC,” said Lynette Dowler, chair of MCCC’s Board of Trustees. “The geothermal-based HVAC system provides state- of-the-art, sustainable energy creation. All to maintain a comfortable environment for teaching and learning. It will serve us well environmentally and financially for many years to come.”_ _“This geothermal asset has a 50-year lifespan on its well field; a conventional upgrade would have lasted less than half that,” said MCCC President Dr. Kojo A. Quartey. “Going geothermal will lower our annual energy costs, save us additional money far into the future because of its long system lifespan, and reduce our carbon footprint year after year. It’s a win-win-win for our college and community now and for many decades to come.”_ ### Some other site-specific features of the geothermal-based HVAC system include mechanical upgrades, such as new water-to-water central chiller cooling/heating plants for: 1) the Campbell Learning Resources Center and East and West Technology buildings, 2) the Warrick Student Services/Administration Building, and 3) the Life Sciences Building, each with capacities of 612, 459 and 286 tons, respectively; a supplemental boiler for the geothermal distribution loop; 10 new air handling units; upgrades to electrical switchgear, transformers and subpanels, and the installation of new electrical meters. In addition, an automated HVAC control system was installed as part of the project that controls not only the geothermal-based system, but also the other conventional campus systems. This was installed at both the Main Campus and Whitman Center in Temperance and offers a user-friendly interface, Web-based access, remote monitoring, and automated alarms and alerts. Ameresco will regularly provide the college with a dashboard of key, building-specific energy performance metrics. All to identify additional savings opportunities and measure the performance of energy upgrades. The company will summarize baselines and trends. As well as  provide the college with a campus-wide view of energy conservation measures. Building by building.
