HONORABLE MENTION | 2020 ASHRAE TECHNOLOGY AWARD CASE STUDIES

Gerald R. Ford International Airport in Grand Rapids,
Mich., had its ﬁrst regularly serviced ﬂight beginning in 1926. Almost 100 years later, Gerald R. Ford
International Airport is continually striving for the highest standards of passenger experience. Most recently,
to improve and enhance passenger service, the airport
needed to relocate its checkpoint areas as well as rightsize the pre- and post-security marketplace programs.
The solution provides a more
functional checkpoint and recomposure area, creating a grand space
with panoramic views of the airﬁeld
through a 26 ft (8 m) high by 178 ft
(54 m) long glass wall system. The
Main Terminal received a 59,000 ft2
(5481 m2) expansion on the east side
and 38,000 ft2 (3530 m2) renovation
of the existing main terminal grand
hall. The marketplace level includes
a seven-lane consolidated checkpoint (ﬁve lanes built immediately
and two future lanes). There are also
retail stores, a kid's play area, a business area, a full-service restaurant,
additional seating, restrooms and a
data center.

Energy Efﬁciency
HVAC was provided by an energyefﬁcient system consisting of displacement ventilation with return
air bypass, energy recovery, variable air volume ventilation and
extensive integrated DDC controls.
The marketplace and checkpoint
area were thoroughly designed to
use displacement ventilation with
return air bypass for dehumidiﬁcation and discharge air temperature
control. This allowed the total airﬂow required to be reduced by 30%
and outdoor air reduced by 20%.

An outdoor air energy recovery unit
with 100% outdoor air bypass for airside economizer serves the air-handling units and provides additional
energy savings.
The air-handling systems use the
existing chilled water system with
waterside economizer and existing heating water system. All the
water coils were optimized for reset
water temperatures and future considerations for lower temperature
heating and higher temperature
chilled water opportunities. Close
to completion of the project high
efﬁciency, condensing heating
plant boilers were engineered and
installed.
Radiant heating along the expansive glass viewing area required
detailed calculations to balance
