Squibb Vivarium Energy Conservation Project
Marc Estra, Bristol-Myers
Bristol-Myers Squibb operates a 1MM SF drug discovery laboratory
in Wallingford, Connecticut. This facility has 150+ research animal
housing rooms which operate 24 x 7 to support the drug discovery
effort at the site. The facility was originally constructed in
1986 and utilized a pneumatic HVAC control system to maintain environmental
conditions in the animal rooms including air exchange rates, temperature,
pressure differential control and in some limited cases humidity.
In 2000 the site Engineering and Veterinary Sciences departments
experimented with electronic based HVAC controls to maintain tighter
environmental control in the animal rooms. Based on the testing
that was performed a project was initiated to convert all the animal
housing rooms to direct digital control coupled to a centralized
building automation system. The new controls will allow the animal
rooms to maintain a tighter range of environmental conditions and
also will reduce the maintenance requirements to operate this facility.
The site has recently embarked on reducing the average air exchange
rates from 18 to 15 per hour due to the higher reliability in the
controls. Additionally, a program has been initiated so that rooms
that are vacant can be shut down remotely to conserve additional
energy. This upgrade also allows room environmental conditions
such as temperature, room air exchange rates and differential pressures
to be rapidly changed so that species can easily be moved from
one room to another.
This upgrade has increased energy conservation, reduced greenhouse
gas emissions and has resulted in more stable environmental conditions
in the animal rooms.
Marc Estra has a Bachelor's degree in
mechanical engineering from Northeastern University and a Master's
degree in engineering from the University of Bridgeport. He is
a licensed professional engineer in the State of Connecticut.
He has over 20 years of mechanical engineering experience working
in the utility industry on coal fired power plant construction
and start-up during the early 1980's and then involved with product
design and manufacturing of diesel engine cooling systems for the
construction and industrial equipment industry. For the past 15
years he is been employed by Bristol-Myers Squibb Company at their
research and development facility in Wallingford, Connecticut.
Mr. Estra is currently responsible for facilities engineering,
construction, maintenance and utilities for the one million square
foot Bristol-Myers Squibb facility in Connecticut. He also leads
a regional maintenance governance board to improve maintenance
and operations productivity within the organization.
Mr. Estra has served on the Advisory Board of the Hartford Construction
Institute and currently is on their Facilities Management Council.
He is also a member of the American Society of Mechanical Engineers
and the International Society of Pharmaceutical Engineers.
