[EN] Commercial buildings account for approximately 18% of the total energy use in the
United States, although only 7% of this consumption is currently supplied by renewable
energy sources, including hydropower, biomass, geothermal, wind, and solar heat and
photovoltaics. This is a low percentage and it is imperative to explore potentials for using a
combination of renewable energy systems to increase this percentage, particularly for large
establishments with large land areas and existing facilities that can support large amounts
of renewable energy technologies, such as airports.
O’Hare International Airport (ORD), located in Chicago (Illinois), has been
selected for this research, with the main purpose of supplying the maximum possible
amount of the airport energy demand by a proposed wind and solar hybrid system. The
first part of this research includes a wind energy system design performed using wind
speed data at ORD locations and determining a suitable number and type of turbines
loacted within the airport premises. Special considerations are made for for height, turbine
locations, and prevailing wind directions. The second part of the study involves design of
solar photovoltaic panel arrays both for existing terminals as well as for a proposed new
terminal. The design of the arrays includes considerations for optimal energy production
with varying installation angles as well as the number of sunny days useful for sun energy
harvesting. Finally, the total electricity output from the hybrid system is estimated and
compared with the total and monthly electricity demand at ORD.
Results show that a considerable percentage of the electricity demand at ORD can
be obtained through the wind and solar hybrid system. Specifically, if the airport authority
decides on a new terminal, the integration of PV panels with the new terminal structure can
be optimized such that the pecentage of total electricty demand at ORD could be met by
more than 50% on-site renewable energy sources. An analysis of potential return in
investment reveals that economically such a design is viable and can result in sizeable
annual savings over a 20-year investment period.
