Utility Management & Energy Benchmarking for Airports April 24, 2014 Charles F. Marshall, Utilities Manager 1
Objectives Benefits of utility invoice analysis in utility performance Trends in metrics and benchmarking utility performance at airports Planning parameters for improvements in utility performance Utility Invoices Energy Design Conservation Management 2
Utility Bill Invoice Analysis 3
Benefits of Utility Bill Analysis Refunds from errors Wrong date, wrong reads, wrong rate, etc. Refunds from optimum rates Real-time pricing vs. regular pricing Adders, etc. Equipment improvements that lower demand should change rates electric CBL (customer base load) Many utility companies have rate departments 4
Benefits of Utility Bill Analysis Refunds from incorrect calculations or misapplication of taxes, especially if the company is government or a non profit Benefits can be gained from all utilities Water, natural gas, and electricity You should not pay sewage for irrigation meter 5
2012 Refunds & Rebates $90,000 $80,000 $70,000 $60,000 $50,000 $40,000 $30,000 $20,000 $10,000 $ Refunds Rebates Water Electricity Gas 6

EPA WEIGHING IN ON AIRPORT BENCHMARKING Building Owners and Managers Association International (BOMA) BOMA International supports voluntary benchmarking and encourages its members to benchmark their buildings at least annually using EPA s ENERGY STAR Portfolio Manager platform or other similar programs. BOMA also supports increased funding for the Energy Information Administration (EIA) to enhance their research and depth of data in the Commercial Buildings Energy Consumption Survey (CBECS) and for EPA ENERGY STAR.

FROM ATL UTILITIES MANAGEMENT AND BENCHMARKING TO PLANNING Plans Completed the Sustainability Management Plan 2011 Completing the Comprehensive Water Audit and Master Plan 2013 Began Comprehensive Energy Management System Assessment
Hartsfield Jackson Atlanta International Airport adopted a Sustainability Management Plan in 2011 that set a number of goals, including the following 20% reduction of water use by 2020 20% reduction of energy by 2020 25
UTILITIES MANAGEMENT AND BENCHMARKING AT ATL TO PLAN TO MAKE SUSTAINABLE IMPROVEMENTS Improvements Energy design to LEED Silver Status or better. Water retrofits Energy audits conducted to identify low hanging fruit Participation in the Atlanta Better Buildings Challenge, which is a part of the DOE s Better Buildings Initiative Use Energy Star Portfolio Manager to compare and measure performance
