AAON Energy and Economics Analysis Program
The AAON Energy and Economics Analysis Program (AAON EEAP) is a tool for
AAON sales representatives, consulting engineers, designbuild contractors, building owners,
and other professionals involved in the design and analysis of commercial buildings to show
the energy and economic benefits of innovative and high performance HVAC technology. It is
part of AAON Ecat program
Weather data was obtained from the bin weather data produced under ASHRAE research project
385-RP, “Development of Bin Weather Data for Simplified Energy Calculations and
Algorithms for Generating Variable Base Degree Day Information” with additional
sites added from the Typical Meteorological Year II Weather Sites developed by the National
Renewable Energy Laboratory.
Monthly profile calculations of occupied and unoccupied periods give this program flexibility and
enhanced accuracy, specifically in modeling schedule options. These monthly profiles are used
for calculating energy usage.
Many features and options available in AAON EEAP cannot be found in any other energy and
economics analysis program, such as variable capacity scroll compressors, evaporative-cooled
condensers, air-cooled condenser fan control, hot gas reheat, and direct drive backward curved
AAON EEAP allows a simple comparison of up to six alternatives in building
construction, scheduling and control, and energy consuming equipment and it can increase your
knowledge of the energy and economic benefits of various alternatives in your building and
The simple mode of operation allows a two alternative energy
and economic analysis to be completed in less than 10 minutes, while the detailed mode of
operation allows a comprehensive energy and economic analysis to be performed between multiple
alternatives. After either a simple or detailed energy and economic analysis is performed a
sophisticated, yet easy to understand, analysis report with weather information, load information,
system information, and plant information presented in graphs, charts, and summaries can be
produced in either a plain text or Microsoft Word® format.
Multiple analysis reports are available such as a one page summary report, a building/load
report, a systems report, a plants report, or a final report containing all of these along
with the charts and graphs from the analysis.
