Honeywell's Healthy Buildings
systems are designed to address
current challenges inside facilities
like airport terminals without
hav i ng to replace ex ist ing
infrastructure. It provides a
holistic view of a building's health
based on factors such as indoor
air quality, occupant f low, PPE
analytics, thermal screening, body
temperature monitoring, social
distancing and sanitation efficacy.
" We want the airport to operate
efficiently and make the airport
safe and know it's safe while
continuing to ensure it's safe and
we want passengers to be confident
when they go to the airport that
they feel safe, " said Colin Dorsett,
global airports business leader for
Honeywell. " All of the technology
solutions being deployed in
Pittsburgh and other airports are
all centered on that foundation of
efficient and safe operations and
increasing the confidence of the
passenger community, because
that's what's going to lead to a
recovery. "
Pittsburgh's xBridge is a
10,000-square-foot innovation area
built to nurture the evolution of
the aviation industry and inspire
creative solutions to challenges. It
allows PIT to test equipment to
see what a post-pandemic airport
can look like before implementing
w ide s pre ad adopt ion of a
technology.
Installation began in July with
completion in November. Testing
has been successful so far and
Hottenfeller said there is discussion
on implementing the system on a
larger scale throughout the airport.
" They've kept their current
30-year-old technology and they're
on a refresh cycle to keep it best in
class, " John Isherwood, sales leader
for the Americas for Honeywell,

said. " They don't let the systems
lag behind what's best in class in
today's current world. "
T he s ystem at x Br id ge
measures indoor air quality
parameters such as temperature,
hu m id it y, c a rbon d iox ide,
particulate matter and volatile
organic compounds (VOC). A
network of 16 IAQ multi-spectrum
sensors connected to the Healthy
Buildings dashboard provides realtime updates on the airport's air
quality performance to help the
facilities staff identify and correct
critical building controls issues.
The system follows ASHRAE
standards to def ine the best
approach to indoor air quality with
data on when to best replace filters.
" If a filter starts to get clogged,
the differential pressure changes
and it has an alarm on the building
management system that would
trigger that for someone to look
at the air handler and the filter in
particular, " Isherwood said.
Carbon dioxide is a predictor
of how many people are in a room.

Rising levels indicate the airport
needs to move air into the area
or check for social distancing,
Isherwood said.
The concept looks at conditionbased maintenance for air handlers
as well. Isherwood said a lot of jet
fuel and dust is kicked into the
air hander units during normal
operations, which means f ilters
need to be replaced more often
than they normally have been.
" Instead of changing the filters
every quarter, semi-annually or
annually based on a maintenance
schedule, you're now changing
the filter based on the condition
of the filter and when it becomes
clogged, " Isherwood said.
Airports deal with different
pollutants compared to other
