Cleanroom Energy Use—Questions NOT Answers
J. Patrick Carpenter, PE, Facility
Performance Engineer
Energy Use in Cleanrooms is one of the most intense building energy
use applications, second only to Data Center Energy use. There are
many things that drive energy use, ranging from the criteria or
cleanliness classification objectives to the system concepts and
even to the operational dynamics of the space. This presentation
looks at the basic drivers of Cleanroom Energy use and provides
insight into the facility objectives and design approaches that
can minimize unnecessary energy use. It suggests challenging many
conventional assumptions and looking at ways to optimize and integrate
the architectural and engineering approaches to minimize overall
energy use in cleanrooms.
Findings:
This seminar will review the basic design issues, approaches and
impacts of engineering mechanical systems in clean rooms. It will
review many of the industry standards and guidelines and identify
the relative energy cost intensity of various parameters and design
assumptions. It will characterize the complex interaction of MEP
systems and present in simple terms how fundamental decisions about
criteria can perhaps be the most significant determinant of Cleanroom
energy costs. By highlighting how Cleanrooms and their magnified
arflow intensities tend to exaggerate the significance of basic
engineering design decisions, it will compare the relative cost
benefits of good engineering practice. It will also provide a basic
decision tree of questions to be answered before attempting to truly
optimize energy use in any cleanroom.
Labs21 Connection:
The goal of this seminar is to aid engineers, architects and owners
in understanding what is involved in an effective energy design
of a cleanroom. It will help the design team achieve more dependable
design decisions with more appropriate and accurate estimates of
energy use in cleanrooms.
Biography:
J. Patrick Carpenter, PE, Facility Performance Engineer,
is a nationally recognized leader in engineering systems for laboratories,
cleanrooms, animal facilities, data centers and other high technology
facilities. He graduated from the University of Pennsylvania with
a Bachelor of Science in Mechanical Engineering and is a registered
Professional Engineer in the states of Pennsylvania and New Jersey.
He has over 35 years experience in the industry and has focused
on the design of engineering systems in high technology projects
for corporate, government and institutional clients for over 25
years. He has been responsible for the conception and development
of MEP systems for many research laboratory, vivarium, and data
center projects and has led the conceptual development of HVAC and
utility systems with emphasis on the safety, reliability, operational
effectiveness and energy conservation of engineering systems for
those and other projects. His experience includes projects for U.
S. Dept. Agriculture (USDA), University of Colorado Health Science
Center (UCHSC), University of MD - Frostburg, Rutgers University,
Food and Drug Administration (FDA), University of Pennsylvania,
University of VA, Environmental Protection Agency (EPA), National
Institutes for Health (NIH), National Cancer Institute (NCI), U.S.Navy,
Cornell University, Merck & Co., DuPont, Johnson & Johnson,
AstraZeneca, Wyeth-Ayerst, Aventis, Pfizer, Glaxo, Boehringer Ingelheim,
Exxon, ARAMCO, Rohm & Haas, Morgan-Stanley and Merrill Lynch.
Patrick has been active in professional organizations such as ASHRAE,
AIHA (American Industrial Hygiene Association) and ISPE (International
Society of Pharmaceutical Engineers). His ASHRAE activity includes
over 18 years involvement with Technical Committees involving Laboratories
and Clean Spaces, Industrial Air-Conditioning and Industrial Ventilation
and Energy Calculations. He also served for 8 years on the Standards
Project Committee which rewrote the ASHRAE Standard 100.5 dealing
with Energy Conservation in Existing Buildings - Institutional and
served on the Standards Project Committee (SPC) which revised the
ASHRAE Standard 110-95 dealing with the Performance Testing of Laboratory
Fume Hoods. He is also involved with the current SPC which is finalizing
revision of Standard 110. He has participated in all Labs21 Conferences
over the last five years making seven presentations and moderating
several sessions and roundtables.
