Energy Independence Outcomes Increase to 2,300 Tons of Heating and 2,000 Tons of Cooling Thru Geo-Exchange Create Jobs to Stimulate Economic Activity Increase to 1.2 MW of Solar Electricity 10,040 Tons of CO2 Emissions Reduced Per Year

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

Conservation (Consume Less Energy) $2.1 Million dollar Energy Performance Contract with Chevron Energy Solutions  Reduce energy consumption by 8%  Reduced Carbon Emissions by 8%  $$Dollars$$ - Saved from Energy Efficiency will Offset the Cost of Implementation Efficiencies Gained by improvements in:  Lighting  Heating/Cooling  Building Controls  Mechanical Systems

New Buildings and Significant Remodels New Buildings Designed to Meet High Performance Standards  Dominguez Hall LEED Gold Certified  Wubben-Science LEED Certified  Houston Hall Green Globes Certified (3 Globes)  Escalante Hall Green Globes Certified (2 Globes)  Tomlinson Green Globes Certified (3 Globes)  Xcel Energy described Dominguez Hall as the most Energy Efficient Building in Western Colorado CMU Dominguez Hall

Conservation (Consume Less Energy) Comparison of Dominguez Hall to Houston Hall prior to remodel Energy Usage Index (EUI)* Dominguez Houston Hall Pre-Remodel Electrical Usage per year KWh842,5181,196,126 Gas Use per year, CCF091,251 Facility Size, GSF56,86271,250 EUI in kBtu/Sf-yr New Classroom Building is 316% More Efficient * Source: EMC Engineers and Davis Partnership Architects

Geo-Exchange CMU Using the Largest Solar Collector in Existence: The Earth  Combined, the Current Fields provide 1,962 tons of Heating and 1,579 tons of Cooling  1,162,728 s.f. of connected load (10 buildings and one swimming pool  CMU has completed four bore fields and has one field currently under construction  The 378 bore holes will combine to provide 189,000 lineal feet of 2.5” diameter pipe - Over 35 miles!  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)

Solar Photovoltaic Energy 300 Days of Sunshine=CMU’s Other Clean Energy Power Plant  CMU has Completed two arrays; one on the Science Building and another on NASH  These Panels Produce 30kW of Clean Energy (18 kW on NASH, 12 kW on Science)  How much additional solar is needed on campus?  Additional solar panels could be placed on the roofs of up to fourteen buildings and one or more parking garages and existing lots
