Strategy 5 Beginning in 2014, City Hall University will continue to its facilities to optimize energy performance and comply with New York City’s Local Law 87. This includes auditing of its existing buildings and identifying low-cost improvements to equipment controls to optimize system performance. This will reduce City Hall University’s electricity consumption by an estimated 1.5 million kWh, which translates to about 634 metric tons of carbon dioxide equivalent. The strategy will reduce energy costs by $20,000 per year and is expected cost only $50,000 to implement, implying a payback period of 2.5 years. The university expects this strategy to make a significant contribution to its goals by reducing its carbon emissions per square foot by an additional 1.3%. five projects represent relatively simple strategies to reduce City Hall University’s energy use and carbon emissions. Taken together, the strategies are projected to reduce City Hall University’s total energy use by about 86,488 MMBtu and cut GHG emissions by roughly 4,882 metric tons of carbon dioxide equivalent. Based on current electricity prices, this will save the university $1,621,000 in energy costs annually with a payback time of 10 years overall. Because there is a degree of uncertainty in all projections, City Hall University will continue to update energy use projections over the next five years to reflect additional evaluation, measurement, and verification of its projects using the 2010 International Performance Measurement and Verification Protocol. Additional Opportunities and General Strategy to Meet the Challenge Goal Based on the results of City Hall University’s LL87 Energy Efficiency Report (EER), the university estimates that it will achieve the remaining carbon reductions to meet the Challenge goal through three main strategies: additional lighting projects; plug load reductions through a combination of energy efficient purchasing standards, software controls, and staff engagement; and on-site generation.
