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

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

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.”
METRICSThe Airport Cooperative Research Program (ACRP) reports metrics in the ACRP 19, “Developing an Airport Performance‐Measurement System”
Environmental Sustainability
• Compliance• Air Quality• Noise• Reuse/Recycle• Energy and Water
efficiency
Electrical power consumption• Energy costs per square foot of
buildings• Utility expense per enplaned
passengers (total number of revenue passengers boarding aircraft)
Water consumption per passenger
AIRPORT ENERGY BENCHMARKING
o Energy & carbon benchmarks for North American airports –Stantec (2012)
o International Airport Benchmarking Initiative – ACI, GTAA & Stantec (2013), includes 16 airports
o IFMA Airport Facility Council – 2012o Web‐based system ( 9 Airports)
o Clean Airports Partnership – 2003o Greek airports – 2003o ACRP – Model for Improving Energy Use in U.S. Airport
Facilities – 2003
Facility Facts
194 facilities totaling 8 million square feet of building assets
3000+ building systems (fire suppression, roofing, HVAC, etc.)

FROM ATL UTILITIES MANAGEMENTAND 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

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
