Environmental Manager Johnson said the City previously reviewed rooftop <br />solar performance, either last year or late the year before, and found that, <br />overall, the systems were delivering solid savings. Some elements, such as <br />demand credits and peak usage reductions, were more difficult to quantify <br />precisely. He noted that panel degradation over time is minimal and that staff <br />have not observed any significant decline in production since installation. <br />Mr. Johnson added that the City may revisit the analysis in the coming years, <br />particularly as planning for the maintenance operations center advances. At <br />that time, staff can evaluate whether to expand existing systems, retrofit <br />current installations, or incorporate additional solar capacity into new <br />facilities. He also said updated information could be shared through future <br />commission packets. <br />Vice Chair Hodder asked whether the City is considering re -roofing the <br />skating center in the future to support potential solar panel installation and <br />expand solar capacity at that facility. <br />Mr. Johnson said re -roofing the skating center to accommodate solar remains <br />under consideration and is still on the City's radar. He recently discussed it <br />with the Parks and Recreation Director, and both departments are interested in <br />pursuing it. However, planning considerations include the timing of roof <br />replacement, structural capacity, panel racking systems, and weight loads. <br />Mr. Johnson noted that the skating center would be an ideal candidate for <br />solar due to its high energy usage and large, open roof area, making it one of <br />the most promising facilities for expanded solar installation. <br />Ms. Bakken added that the skating center offers significant roof space that <br />could be well utilized for solar. She noted that the booster station project this <br />year is maximizing available roof area. Even with that effort, it will only <br />offset about 5% of that facility's energy use because it is such a high-energy <br />consumer. Given the skating center's large roof and substantial energy <br />demand, she said it presents a strong opportunity to expand solar generation <br />meaningfully. <br />Vice Chair Hodder commented that it would be beneficial if the school district <br />and retail property owners with large flat roofs also invested in solar <br />installations. He noted that those buildings present strong opportunities for <br />solar generation, though he acknowledged that those properties are outside the <br />City's direct jurisdiction. <br />Ms. Bakken shared that she regularly encourages Rosedale leadership to <br />consider installing solar, noting the significant rooftop space available. She <br />believes there has been positive movement, as Rosedale has become more <br />engaged with Earth Day activities and appears increasingly interested in <br />sustainability efforts. She also mentioned encouraging the installation of <br />Page 13 of 18 <br />
