Page 111 Group14 modeled predicted site EUl,upfrontcosts,and annual energy costs for each building type to achieve the NBI EUI targets (see Table 3) under this policy option. The Group14 model investigated the most cost-effective means of achieving the NBI standards using both efficiency and onsite PV to reach each standard. Note, this differs from the NBI methodology, which only incorporated energy efficiency measures to meet each target.

GREENHOUSE GAS EMISSIONS To assess how this option m ight contribute to Louisville's em issions reduction goals, Group14 also modeled GHG em issions resulting from a building achieving its energy performance standard, based on the building type. Energy performance standards help to drive up energy efficiency and drive down building emissions,as illustrated in Figures 1 a n d 2.In each building type, for mixed fuel and all- electric system s,a building that has achieved its energy perform ance standard creates less GHG em issions than the sam e building compliant with current code.
