This chapter emphasizes the importance of applying the calculators for assessing
the energy usage and pollution prevention for a hypothetical facility in Ohio. As a part of
the study, we identified lighting fixtures and suggested alternatives for energy reduction
and pollution prevention. We performed an energy assessment survey of the entire facility
using the Energy Assessment Spreadsheet (EAS) tool developed at The University of
Toledo to calculate reductions in energy use and costs associated with energy consumption
of lighting fixtures. As a result, there is a reduction of electricity usage from 2,056,942 kilo
Watt hour (kWh) to 1,477,059 kWh, or nearly 30% less energy expenses with an annual
savings of over $55 thousand. Additionally, we performed a life cycle assessment using
Economic Input Output Life Cycle Assessment (EIO-LCA) to determine the change in
environmental impacts due to the use of energy efficient lighting. EIO-LCA revealed a
reduction in Carbon Dioxide (CO2) gas emissions from 1,830 metric tons to 1,300 metric
tons, which is approximately 30%. The pollution prevention (P2) calculator comprising of
P2 Green House Gas (GHG) tool and the P2 Cost Calculator developed by the United
States (U.S.) Environmental Protection Agency (EPA) was the third tool applied. The
greenhouse gas reductions were calculated using the P2 GHG tool while cost savings
related to energy savings were calculated using P2 cost calculator. There was a reduction of
492.823 metric tons of Carbon Dioxide equivalents (MTCO2e) GHGs for the electricity
savings of nearly 580,000 kWh.
