MOTION: Mayor Sisk moved the budget session scheduled for June 27,2006 be conducted as a special meeting, commencing at 12:00 p.m., at the Louisville Municipal Court. Council member Marsella seconded the motion. All in favor. REGULAR BUSINESS PRESENTATION - PHOTOVOL TAlC FEASIBILITY STUDY FOR NEW LOUISVILLE PUBLIC LIBRARY (ARCHITECTURAL ENERGY CORPORATION) Mayor Sisk requested a Staff presentation. Deputy City Manager Boyd reported on the City's agreement with Architectural Energy Corporation for professional services for the installation of a photovoltaic (PV) power system on the roof of the new Louisville Public Library. The first phase of the three-phase agreement is for completion of a feasibility study, including an evaluation of the preferred type of system and an economic analysis of the system including payback period with available rebates. Should Council decides to proceed with the project, the second phase will include preparing construction documents for bidding out the work to purchase and install the system, and the third phase will be commissioning of the system as it is designed and installed. The contract amounts are as follows: The Feasibility Study - $ 4,120.00; the Design & Bidding of System - $3,790.00; and the System Commissioning - $7,385.00, for a total of $15,295.00. Architectural Energy Corporation (AEC) representatives Tom Hickey and Mike Johnston were directed to provide more information about the feasibility of the PV system, including adding the soft costs to the cost estimate, assuming increasing energy costs for the life of the system, anticipated replacement cost of the inverter, and evaluating larger systems. A new report was prepared, which includes information for the originally proposed 10 kW system, a 25.5 kW system and a 51 kW system. With the addition of project soft costs, the pay-back period for the 10 kW system has increased from 38.9 years to 48.7 years for the discounted payback, even assuming increasing energy costs. The system's life is expected to be 20-25 years. Information presented at the previous meeting estimated that the 10 kW system would produce approximately 20% of the library's power needs. The Renewable Energy Credit of $2.50 per kW is not available for systems larger than 10 kW, increasing the pay-back period for systems larger than 10 kW. AEC staff noted from an economic analysis the costs for solar energy do not make the systems feasible and considerations such as
