Feature

Critical
considerations
for specifying a
building automation
system for health care
By Damian Skelton, MBA, PE, CHFM, vice president, Medxcel Facilities Management; Jason King, building automation specialist,

O

ne of the least understood
and most expensive
systems in a hospital is
the building automation
system (BAS). Controlling
every aspect of the heating,
ventilation, and air conditioning system,
from chillers to boilers to air handling
units to variable air volume boxes and
more, the BAS is the primary backbone
for managing facility operations and
energy consumption in a hospital. The
benefits of a well-designed BAS include
ensuring HVAC systems' operational
performance, reducing energy costs, and
keeping the employees, patients, and
visitors comfortable.
As technology continues to advance,
more systems-fire alarm, power
monitoring, lighting control, and
security-are being integrated into the
BAS. With the convenience of having a
streamlined system comes additional
code requirements and complications.
Because of this, more deliberate
communication must be created between
the various stakeholders, including the
owner, designer, commissioning agent,

construction team, and on-site HVAC
operations department.
Some health care executives direct
engineers to make multimillion dollar
decisions on which manufacturers BAS
to use in their facilities, without either
the executive or the engineer fully
understanding the effects associated
with this important decision. The choice
of BAS has long-term ramifications and
affects almost every aspect of facility
operations and maintenance; therefore,
the decision should not be based on
second-hand experience, manufacturer's
sales representatives' presentations and
sales pitches, or unvetted third party
recommendations. The BAS controls
almost all of a hospital's critical utility
systems, and more than 50 percent of the
facility manager's budget is invested in
energy. The building automation system
should be one of the specifying engineer's
primary focuses, and due diligence is
essential when making these decisions.

Fundamentals
The BAS is a facility maintenance
department's primary view into

the operations of the HVAC system
in the hospital. HVAC and facility
technicians who will be using the BAS
are under pressure to minimize the
time to monitor, evaluate, adjust, and
troubleshoot daily operations. They
are responsible for creating spaces
that are comfortable for the occupants
while meeting the appropriate codes.
This is especially vital in a hospital
where patient comfort directly affects a
patient's well-being and ability to heal.
The BAS is a tool that the facility staff can
use to simplify the task of maintaining
the comfort level for patients and the
staff who treat them.
In a perfect world, the patient would
have control of the room temperature
right next to the bed. Too many times
nursing staff or visitors adjust the
thermostat for their own comfort, and
the patient suffers. This eventually is
reflected in patient experience scores
such as those collected by the Hospital
Consumer Assessment of Healthcare
Providers and Systems (HCAHPS). Using
the BAS to control setpoints can help
ensure the patient's comfort.
