Therefore, some ICE's ore still necessary for the initial phases of this plan. <br />See the appendices of the building audit reports for detailed descriptions of scope for each decarbonization <br />measure. <br />Miscellaneous Electrification <br />Replace -40 % of remaining gas equipment <br />Renewable Phasing <br />Renewables are recommended to be implemented right away to take advantage of existing federal and state <br />funding options. <br />Efficiency & Load Reduction Phasing <br />Efficiency & load reduction measures are recommended to be implemented right away to realize any <br />potential downsizing for mechanical and electrical systems as buildings are upgraded in the future. <br />Recreation Center Phasing <br />The Recreation & Senior Center measures are split into two phases. The first phase addresses the majority of <br />the RTUs that are near end -of -life and one of the pool natatorium dehumidification units (NDHUs). <br />Near Term Summary Table <br />Add -On <br />Potential Add -On <br />Metric Near Term <br />Tons Electric Emissions <br />EC <br />O2e] <br />4,000 <br />3,500 <br />31000 <br />Renewables <br />$9-11OM <br />2,500 <br />[$2.7MTax <br />Credit] <br />2,000 <br />1,500 <br />Efficiency & <br />Load Reduction <br />8200-250k <br />1,000 <br />Clean <br />500 <br />; Grid <br />0 <br />Life Cycle Carbon <br />Total <br />Total Like -for -Like <br />Net <br />Reduced <br />Construction <br />Construction <br />Construction <br />Measures <br />[tonnes] <br />Costs* <br />Costs* <br />Costs* <br />fA <br />Building Hybrid Electrification <br />13,000 <br />$12-1611 <br />$8.1-9M <br />$3.9-711 <br />Fleet Electrification <br />1,300 <br />$4-511 <br />$3.5-411 <br />$0.5-1M <br />Miscellaneous Electrification <br />1,000 <br />$1.5-2.511 <br />$0.9-1.511 <br />$0.6-114 <br />Efficiency & Load Reduction <br />2,400 <br />$0.4-0.514 <br />$0.4-0.511 <br />Renewables <br />- <br />$9-10M <br />$9-10M <br />Total 17,700 $27-34111 $13-15111 $14-20M <br />*Costs do not include incentives or grants.
