Putting Your Existing Cleanroom on an Energy Diet
Vincent A. Sakraida, P.E.,
Stanley Consultants, Inc.
Cleanrooms are among the most energy intensive facilities
operated. Typically, most existing cleanrooms are designed and operated
to meet the worst case operating conditions, which only occur several
hours during a given year, resulting in extensive wasted energy
during the remainder of the year. This presentation looks at relatively
economical energy saving modifications that can be implemented in
existing cleanrooms to reduce overall energy usage. The specific
cleanroom modifications to be discussed include variable supply
air flow controlled by active space particle monitoring, sensitive
process isolation, space cleanliness classification reduction, space
pressurization reduction, and cleanroom air exfiltration reduction
by sealing cracks and openings in cleanroom walls and ceilings.
Labs21 Connection:
The Labs21 Approach philosophy being incorporated in this presentation
is the optimization of building efficiencies. Cleanrooms utilize
substantial energy for heating, air condition, and air movement.
Typically, most existing cleanrooms are designed and operated to
meet the worst case conditions which only occur several hours a
year, resulting in extensive wasted energy during the remainder
of the year. This session presents modifications that can be implemented
for minimal capital investment and disruption to cleanroom operations
while providing substantial energy savings.
Biography:
Vincent A. Sakraida, P.E., is a Senior Mechanical Engineer
at Stanley Consultants, Inc., a Denver-based engineering consulting
practice, and is a recognized leader in engineering systems for
laboratories, cleanrooms, hospitals, pharmaceutical production facilities,
and other high technology facilities. He graduated from Georgia
Institute of Technology with a Bachelor of Science in Mechanical
Engineering and is a registered Professional Engineer in the states
of Colorado, Ohio, Indiana, and Michigan.
He has worked over 24 years performing engineering design for high
technology projects for corporate, government, and institutional
clients. He is responsible for the MEP system assessment, program
development, schematic design, design development, construction
documentation, construction administration, and commissioning for
R&D laboratories, hospitals, pharmaceutical production facilities,
electronic assembly facilities, and plastic manufacturing cleanrooms.
Recent work includes projects for Westinghouse Nuclear Services
Group, Allina Healthcare, Bayer Corp, and University of Colorado.
Vincent has been active in professional organizations such as the
Association of Facility Engineering, the American Society for Healthcare
Engineering, and the International Society of Pharmaceutical Engineers.
He has presented seminars at three national conferences and numerous
seminars at regional conferences. The national conferences seminars
include Project Management presented at the Association of
Facility Engineers 2003 Conference in New Orleans; Planning and
Constructing a Contamination Controlled Environment presented
at the April 2004 Cleanroom East Conference in Orlando, FL; and
Buried Energy Savings in ISO5 Cleanroom HVAC System Design Details
presented at the October Labs21 2004 Annual Conference in St. Louis,
MO. Regional seminars include Cleanroom Design: Everything you
wanted to know about a cleanroom, but were afraid to ask; Laboratory
Basics; CGMP Basics; Validation Basics; and Commissioning
Basics. Cleanroom Design seminar participants received a 200
page unpublished book written by Vince.
