l�'�, <br />Jy <br />REQUEST FOR COUNCIL ACTION <br />Department Approval <br />�-. <br />Date: July 27, 2009 <br />Item No.: 12.c <br />City Manager Approval <br />Item Description: To Pursue Federal Stimulus Recovery Act - Geothermal Technologies <br />Program <br />BACKGROUND <br />Suildings in the US today consume 65% of the nations' electricity and 35% of the total energy <br />use. The Roseville Geothermal Campus Master Plan looks at reducing the use of fossil fuels by <br />exploring an integrated geothermal system that uses both the waste heat from the ice rinks and <br />the constant temperature of the earth for energy storage. As part of the process to convert the <br />Roseville Indoor Skating Center to a geothermal system, KFI (Karges-Faulconbridge, Inc.) <br />investigated the feasibility of expanding this system to include City Hall and Police, and the <br />Public Works Facility. After the first six months of operation, temperatures of the well field <br />showed that the Indoor Skating Center is not using all of its stored energy. To be more efficient <br />and use all of the stored energy, we would need to expand the current geothermal system to other <br />city facilities. This will require other piping loops to be added. <br />Sy expanding the current geothermal system to the maintenance building and city hall, KFI <br />calculates a total estimated energy savings of $55,000 -$65,000 per year. <br />As a part of the American Reinvestment and Recovery Act the Department of Energy is <br />soliciting applications for project using heat exchange technologies. These applications are due <br />in mid August. The m�imum request is $5,000,000. This particular category of grants requires a <br />50% local match. Staff is requesting the Council consider authorization for staff to move forward <br />with this application. <br />POLICY OBJECTIVE <br />The City Council has supported green initiatives to reduce the city's carbon footprint when <br />economically feasible. The proposed ARRA Federal Stimulus Recovery Act - Geothermal <br />Technologies Program Grant is consistent with our Energy Action Plan and Imagine Roseville <br />2025 initiatives. <br />FINANCIAL IMPACTS <br />This grant requires a 50% local match. The estimated project cost for the extension of the <br />system is $2,308,960. In order to expand the geothermal system to additional buildings, much of <br />the conventional HVAC equipment will need to be replaced. The following is a cost estimate for <br />the extension of the system to the maintenance building and city hall. <br />Page 1 of 3 <br />
