Project Summary
Trane Wireless Zone Sensors speed the construction process at a large school district in Missouri.
Liberty Public Schools serves residents
of about 85 square miles of Clay County,
northeast of Kansas City. The District includes
a preschool, ten elementary schools, two
middle schools, two junior high schools,
a senior high school and a second senior
high school scheduled to open in 2010.
Liberty Public Schools has been named a
“High Performing School District” by the State
of Missouri for six consecutive years—the
highest accreditation given to a Missouri
school, recognizing Liberty Public Schools as
one the state’s best school districts. Liberty
students consistently score above state and
national norms on standardized tests, have a
graduation rate of 90.8 percent and more than
90 percent of graduates seek higher education.
Liberty Public SchoolsHVAC and Control Systems Upgrades • Liberty, Missouri
The district was one of only three schools in the
nation honored by the National School Boards
Association for technology excellence. Liberty
is being used as a State of Missouri model
for effective use of technology in learning.
ChallengeIn early 2007 the Liberty School District
initiated a project to renovate and upgrade
the HVAC systems and equipment throughout
the district. As part of the project, the district
also wanted to install and integrate the HVAC
systems with a single, district-wide building
control system. At that time the school district
had Trane HVAC systems in five of the schools
and control systems from two other suppliers
in the other 10 school buildings. Four of the
schools had no control systems. Magnifying
the challenge was the requirement that all work
needed to be completed during the summer
of 2007, before students returned to class.
SolutionWorking with Dan Ketelle in the Kansas City
Trane office, Liberty School District replaced
many of the old HVAC units with new Trane
products for improved efficiency, comfort
control and reliability. Liberty Schools also
opted to purchase a Trane Tracer ES™
automation system for district-wide control.
In the schools where Trane HVAC equipment
is used, Trane also recommended installing
their newly developed wireless zone sensors
to speed the installation process. Wireless
zone sensors eliminated the time and
expense associated with hard wiring.
ResultsBy using Trane wireless sensors the HVAC
upgrades in schools with Trane equipment
were completed on time before school opened
in the fall of 2007. Schools not using Trane
systems were not finished until 2008. Trane
wireless sensors improved the construction
process by eliminating the need for hard wiring.
Without the need for conduit and wiring, Trane
wireless zone sensor technology is perfect
for new construction, remodels and retrofits.
No hard wiring provides substantial savings
in time and money by eliminating the need
for wiring schematics, conduit and running
wires. Wireless sensors are simply placed where
desired. When space configurations change,
the sensors can be quickly and easily moved
to a new location. Working with a Trane Tracer
ES system, the zone sensors provide better,
targeted control of temperatures and humidity.
Steven Aldrich, Director of Maintenance at
Liberty School District, said, “Installation of
the wireless sensors definitely expedited the
installation/construction process which is a
very important feature when dealing with the
small windows of opportunity—spring break,
Christmas break, summer break—that we usually
have to accomplish projects of this nature.
“The biggest advantage of the wireless
sensor is the fact that it’s easily relocated.
On occasion we are required to reconfigure a
classroom (or classrooms) to support a new
course of instruction or to accommodate
our growing student population. The
ability to easily and almost instantaneously
relocate the sensor anywhere in the
room during the course of remodeling or
construction gives us complete flexibility.
“The wireless sensors operate as well as
our hard-wired sensors. When you couple
the operating characteristics, which are
virtually the same as a hard-wired sensor,
with the ease of installation, it makes the
wireless sensor a very attractive option.
Aldrich concluded, “I’m pleased with the
performance of our wireless sensors. They
expedited the installation process and
gave us options for sensor placement we
wouldn’t have had with hard-wired sensors.
In addition, they allow flexibility and ease
of sensor relocation if future construction
or remodeling projects require this.”
