<br /> City Council <br /> Meeting Minutes <br /> June 20, 2006 <br /> Page 4 of 7 <br />reducing energy produced by coal-fired power plants and advancing innovation <br />must be taken into consideration. <br />AEC and staff have researched availability of grants and other funding from state <br />and federal agencies, Xcel Energy, and research groups such as NREL. Grants <br />and technical assistance are available for residential systems, and for large-scale <br />systems with a minimum size for a new or renovated building of 50,000 square <br />feet. The library is approximately 32,000 SF, and the City Hall is about 17,000 <br />SF, making this source of funding unavailable. <br />Mayor Sisk requested a presentation from the consultant. <br />Mike Johnston, Architectural Energy Corporation, (AEC) reviewed the preliminary <br />quotes for the three solar systems, the unit costs versus the system size, and the <br />number of years in which the system would payback the investment. The10 kW <br />System would be $83,000, with a potential rebate of $45,000. The 25.5 kW <br />System would be $199,674, with a potential rebate of $52,000. The 51 kW <br />System would have a cost of $314,934.000, with a potential rebate of $102,000. <br />Library Director Mojo reported the library project manager contacted the roofing <br />representative relative to the installation of rooftop ballast systems. The <br />representative stated the roof was not anticipated or designed to have anything <br />added to it. The library's roof warranty would be compromised by the installation <br />of the ballast system, or any additional work required on the roof to support the <br />system. <br />Mayor Sisk requested information on alternative energy efficient systems for the <br />new library. Mr. Johnston stated there is technology in hot water systems. He <br />noted photovoltaic is on site and therefore preferable. <br />Mayor Sisk asked about the feasibility of wind power. Mr. Johnston stated wind <br />power would not be practical at the site. He noted another option would be a pre- <br />heated ventilation system, which is a visible system. <br />Council member Muckle reported receiving an email from Doug Grinbergs <br />relative to a Sun Edison program, which will build, own and operate solar projects <br />and lease these systems to municipalities and companies. He suggested the City <br />buy energy from such a company. <br />Mayor Sisk explained leasing arrangements are prohibited by the City's Home <br />Rule Charter. City Attorney Light stated the Home Rule Charter prohibits leasing <br />of equipment, but he would investigate whether such a third-party purchase of <br />energy would be compliant with the Charter. <br />Mayor Sisk suggested energy efficient systems be purchased through the bond <br />
