CAMPUS ENERGY COST SAVINGS CASE STUDIES: APPLICATIONS OF ENERGY BEST PRACTICES

摘要

Global businesses continue to experience regular and significant cost increases in energy costs. Most companies have established energy and environmental sustainability commitments / policies which address decreasing energy emissions, and indirectly lower costs. At Armstrong, a corporate goal was established in 2008 to reduce Green House gas emissions 10% from 2006 baselines by the year 2015. In 2009, Armstrong completed a greenhouse gas inventory third-party verification from the established 2006 baseline year through 2008. Our partnership with The Climate Registry assisted in ensuring measurement accuracy. While the corporation already surpassed the 2015 reduction goals, the achievement was largely a result of a decrease in manufacturing production tied to the overall downturn in the economy. The company continues to be committed to projects that decrease energy usage and our environmental impact. In 2007, Armstrong initiated several projects at its Corporate Campus to continue process improvements that reduce energy usage and costs. This paper describes these projects and the energy cost reductions that resulted from their implementation. Together, these projects have resulted in significant energy usage reductions - more than 2,950,000 kWh, about a 16% overall reduction compared to the 2007 base period. Since Pennsylvania regional electric rate cap expiration at the beginning of 2010 significantly increased electrical costs, the annualized electricity cost savings will be about $280,000 this year. Aggregate annual savings including boiler fuel savings are expected to be about $327,000 or 11.6% of total Campus energy costs in 2010, compared to 2007.
