The City of Port Arthur engaged Siemens to conduct an investment-grade audit of the City’s infrastructure. The City wanted Siemens to identify facility improvement measures that would: • Address needed facility updates • Improve the energy efficiency of city facilities • Reduce utility and operational costs • Minimize impact on capital funds In late 2011, Siemens presented the audit results to the City of Port Arthur, and in early 2012, the City decided to move forward with a selection of facility improvement measures.
