Long Range Goals Consume 50% less Energy Purchase 90% less Energy Conservation High Efficiency

Long Range Goals Consume 50% less Energy Purchase 90% less Energy Conservation High Efficiency Equipment, Technology and Buildings Goals Attained by: Geo Exchange Heating and Cooling Solar Power

Conservation (Consume Less Energy) $2. 1 Million dollar Energy Performance Contract with Chevron Energy

Conservation (Consume Less Energy) $2. 1 Million dollar Energy Performance Contract with Chevron Energy Solutions ØReduce energy consumption by 8% Ø Reduced Carbon Emissions by 8% Ø $$Dollars$$ - Saved from Energy Efficiency will Offset the Cost of Implementation Efficiencies Gained by improvements in: ØLighting ØHeating/Cooling ØBuilding Controls ØMechanical Systems

Geo-Exchange CMU Using the Largest Solar Collector in Existence: The Earth Ø CMU has

Geo-Exchange CMU Using the Largest Solar Collector in Existence: The Earth Ø CMU has completed four bore fields and has one field currently under construction Ø The 378 bore holes will combine to provide 189, 000 lineal feet of 2. 5” diameter pipe - Over 35 miles! Ø Bore fields are connected into 18” dia. pipes that deliver the geo resource to buildings across campus, allowing heat energy to move between buildings, the natatorium, the ground & other heat sinks yet to be developed (tail water heat exchanger) Ø Combined, the Current Fields provide 1, 962 tons of Heating and 1, 579 tons of Cooling Ø 1, 162, 728 s. f. of connected load (10 buildings and one swimming pool

Solar Photovoltaic Energy 300 Days of Sunshine=CMU’s Other Clean Energy Power Plant Ø CMU

Solar Photovoltaic Energy 300 Days of Sunshine=CMU’s Other Clean Energy Power Plant Ø CMU has Completed two arrays; one on the Science Building and another on NASH Ø These Panels Produce 30 k. W of Clean Energy (18 k. W on NASH, 12 k. W on Science) Ø How much additional solar is needed on campus? Ø Additional solar panels could be placed on the roofs of up to fourteen buildings and one or more parking garages and existing lots https: //solarthermalmagazine. com/wp-content/uploads/2015/04/solaire-generation-solar-parking-lot-structures. jpg http: //www. paulblacks. com/images/gallery-4. jpg
