Pursuing LEED Gold – 60 Points Required Currently at 68 Leadership in Energy & Environmental Design Energy Savings Measures 420 ton closed-loop geothermal heating and cooling system Chilled beam cooling system Variable air volume air handling units Energy recovery on air handling units Variable volume heating and cooling pumps High efficiency domestic water heating system Variable frequency drives for motors Building-integrated photovoltaics Transformers bearing Energy Star labels High efficiency light fixtures Lighting controls  Occupancy sensors  Daylight harvesting sensors  Multiple switching zones  Use of low mercury lamps Thermally efficient glazing (low-E coatings, ceramic fritting) Reflective white roofing membrane Enhanced commissioning Upon completion, Rock Valley College will likely be the first community college in Illinois to have two LEED Gold projects on its campus.

Saavedra Gehlhausen Architects Closed-Loop Geothermal System The closed-loop Geothermal system include (8) water-cooled heat pump units, primarily loop water pumps, a 164 vertical well geothermal bore field, and associated piping. This system will work to create jobs, reduce energy consumption and greenhouse gas emissions, and leverage grant funding in a learning environment that can promote these initiatives to future generations. ADVANTAGES More efficient than the existing central heating and chiller water plant Places the project in a better position to obtain LEED Gold Certification than more traditional systems Excess capacity will be shared with CL-I building Supports the College’s long standing “green” philosophy Can be used as a teaching tool for sustainable design SYSTEM ECONOMICS Geothermal System Cost $1,783,000 Less Conventional System Cost($ 695,000) DCEO Grant (Pending)($ 420,000) ICECF Grant (Pending)($ 90,000) Remaining Project Cost $ 578,000 Modeled Annual Energy Cost Savings Compared to Traditional System:$76,000 Simple Payback (Including Grants)7.6 years
