St. Louis Park has several opportunities to use its public sector solar resources. The city's rooftop solar resources are substantial and may, in some cases, meet a significant portion of on -site electric energy use in the same building. Most sites have the potential to receive at least 25% of energy consumption from rooftop solar. The Municipal Service Center may be able to capture up to 171% from solar, which exceeds the benefits of net metering (net metering is limited to 120% of customer's on -site annual electric consumption). To capture the full benefit of solar on this roof space, the city should explore community solar. City Action: The city has a goal to achieve 100%of its electricity from renewable sources by 2030. This can be achieved at the city operations level through a combination of actions. • Set an internal goal to receive at least 10%of the city's electricity from on -site solar • Use the solar mapping to prioritize which buildings the city intends to install solar on • Explore solar carport opportunities for parking areas (see Mill Valley Rec Center) • Complete solar site assessments with a solar installer for priority buildings • Complete a structural analysis and electrical service evaluation of rooftops • Maximize rooftop solar on all public buildings with a good solar resource • Ensure there is an element for storage plus solar, or storage -ready solar in any RFP issued by the city • Use the city's sustainable purchasing policy to purchase on -site solar installations and/or renewable energy credits for the remaining electricity (the electricity that is not covered by on -site solar) • Identify financing and incentive opportunities (rebates, production incentives, third -party financing) • Explore opportunities for ground -mount systems to increase the amount of local generation • Track progress and share success The city can maximize building energy efficiency by implementing the following: • Ensure all buildings and facilities are benchmarked and kept up-to-date in B3 o Work to have all utility bills automatically uploaded to B3 database o Consider Portfolio Manager as an additional or alternative benchmarking tool (133 and Xcel allow for automatic uploads to Portfolio Manager), buildings maybe eligible to achieve ENERGY STAR certification • Participate in State financing programs like the Guaranteed Energy Savings Program (GESP) or Local Energy Efficiency Program (LEEP) • Prioritize improving the efficiency of the city's largest energy user (i.e. the Rec Center) o Consider solar thermal heating for the pool o Explore opportunities for ground -source heat -pumps for the ice arenas o Expand white roof to the entire rooftop • Require green building or net -zero energy standards for all new public buildings, and for major renovations of existing buildings • Encourage energy efficient behavior changes by all staff (e.g. turn computers off at night, eliminate any personal space heaters or refrigerators) The following measures can be tracked using GreenStep Cities Step 4: • Number of city -owned and private renewable energy generation sites • Generation capacity at city and at private renewable energy generation sites • Annual renewable energy purchases • Percent of total energy use that is generated and purchased renewable energy • Percent of total city energy use that is purchased from a community solar garden
