Recommended Targets for New Facility or Renovation Project Based on the City Hall’s programmatic needs as well as on the review of the existing site included in this report, the following strategies are recommended for consideration for any new construction or renovation project for the City of Arden Hills City Hall. Strategies should be revisited and amended as appropriate as project concepts are developed. Site Characteristics: Tree Canopy Cover: >37% Total Impervious Surface: <24% Recommended B3 strategies (in addition to “Required” strategies): Maximize tree canopy contribution by planting trees to cover/shade paved areas, goal of 50% of non-parking surfaces shaded within five years and 50% of parking surfaces shaded within ten years. Minimize impervious surface area through use of green roof assemblies. Minimize heat island impact through use of green roof assemblies and/or use of ENERGY STAR roof-compliant, high- reflectance, AND high emissivity roofing (initial reflectance of at least 0.65 and 3-year-aged reflectance of at least 0.5 when tested in accordance with ASTM #903 and emissivity of at least 0.9 when tested in accordance with ASTM 408) for a minimum of 75% of the roof surface. Reduce transportation impacts by: · Locating the building within 0.25 mile of one or more bus lines. · Providing means for securing bicycles, with convenient changing/shower facilities for use by cyclists, for 5% or more of building occupants · Installing alternative-fuel refueling or plug-in electric vehicle charging station(s) for 3% of the total vehicle parking capacity. Energy and Atmosphere: Recommended B3 strategies: Increase energy efficiency of building to meet SB2030 Energy Standards. Recommended minimum EUI target of 44.5 as reviewed in Section 2 of this report. Provide a minimum of 25% of the building’s energy needs through on-site renewable energy (solar or wind). Minimize impervious surface impact of solar installation by installing array on roof surfaces not receiving green roof assemblies, integrated with green roof assemblies, integrated into building facades and sun control devices, or installed over pavement sections as carport/shade device. Meet the Atmospheric Protection requirements of B3 strategy E.4. Indoor Environmental Quality: Recommended B3 strategies (in addition to “Required” strategies): Meet the View Space and Window Access requirements of B3 strategy I.9. Materials and Waste: Meet all “Required” B3 strategies. Site Sustainability Metrics 4- 3 City of Arden Hills Energy and Sustainability
