HVAC Design and Its Relationship to Fire Litigation
In today’s atmosphere in which most serious accidents result in some form of litigation, engineers must
design and build structures with the utmost care and concern for the safety of all occupants. In the event
of a fire, occupant safety involves consideration of not only obvious systems such as the sprinkler and fire
alarm systems, but also consideration of the HVAC design, HVAC operation and selection of the building
contents. Since most loss of life in a fire results from smoke inhalation rather than burns, the designer
and builder of a structure must be aware of how their participation in the building will affect the safety of
the occupants who utilize their building.
This talk will focus on the influence of building design and construction on the development and
movement of smoke when a fire occurs in a building. Examples will be taken from several major fires
including the MGM Grand Hotel fire in Las Vegas, the DuPont Plaza Hotel fire in San Juan and the
Cathedral Hill Hotel fire in San Francisco. The litigation that evolved from these fires will be used to
suggest ways that engineers can minimize the impact of fire litigation if it should occur.

VAV System Design: Problems and Opportunities
This talk explains the history and the physical principals of VAV systems. After exploring the genesis of the
concept, the evaluation of state-of-the-art systems is presented from a critical perspective. Through an
analysis of the deficiencies in the performance and economic parameters, concepts of systems based upon
elementary thermodynamics and fluid theory coupled with decreased complexity will be presented.
Air Conditioning Systems for Improved Comfort and Air Quality
Indoor air quality is of increasing concern as society redefines the needs of the indoor environment. This talk
presents a new perspective on the topic, starting with the fundamental dynamics of psychrometric instability
and its affect upon the controlled environment. System directed solutions will be presented which reflect a
significant departure from existing design practices.
A Fundamental Perspective on Chilled Water Systems
With chilled water systems, as with most other engineered energy systems, the parameters of performance
and energy efficiency are totally synergistic. However, as these systems have grown in size they seemed to
have grown in complexity and performance problems resulting therefrom have led to numerous publications
and papers on how to fix the problems. This talk examines the fundamental objective and physics relating
to chilled water system design and suggests design guidelines for all practitioners from entry level engineers
to experienced professionals.
The Ethics and the Economics of Energy Conservation
This talk explores the economics of energy conservation and the failure of economic alternatives in the
search for more energy conservative buildings and machines. Then, based upon this observation an
alternative perspective leads to the conclusion that energy conservation is an ethic, and if this ethic is
embraced by those who practice in the energy sciences, the inevitable result will be improved system
performance, energy conservation and economics.

Technical Issues Impacting HVAC&R
Technical problems become issues when there is government involvement or anticipated governmental
activity. Environmental concerns are the principle driving forces on many of those issues affecting the
HVAC&R industry - whether it be issues surrounding many of today's refrigerants, energy conservation
measures to reduce greenhouse gas emissions or indoor air pollution concerns.
On ozone depletion issue, there have been no recent changes to the provisions of the Montreal Protocol,
although implementation of the terms of these agreements continues. The U.S. remains below the
current allowable HCFC "cap." Climate change is a rapidly developing global issue. The scientific
understanding of the global-warming phenomena is advancing. The international community has initiated
the first binding agreement, the Kyoto Protocol. Since HFCs are identified as a targeted greenhouse gas,
some countries are seeking policies limiting the future of HFCs.
Refrigerants available for the long-term future will be affected by how these global environmental
concerns are addressed. An update will be provided on the status of the international agreements, and
the processes for implementing policies in the HVAC&R industry.
Renewed interest in energy conservation will be an important component in reducing greenhouse gas
emissions. The U.S. Department of Energy is publishing findings from numerous studies on energy
consumption of buildings, building systems and system components. The purpose of these studies is to
identify opportunities for additional energy savings.
Even though indoor air quality problems exist, the issue has not resulted in many actions by legislative
and regulatory bodies, although proposals have emerged through the years.
Individual issues generate their own momentum and sequence of events. The importance of specific
issues may rise or fall with the calendar. Topics discussed will reflect the current areas of activity.

The ASHRAE Member’s Survival Guide
This general legal education program focuses on legal and non-legal steps that ASHRAE members can
take to avoid being sued, and to limit their exposure if they are sued.
The first segment of the program identifies many of the risks that ASHRAE members face (including risks
arising out of plans and specifications, cost estimates, site visits, environmental hazards, project delays,
changed conditions, and lawsuits), and discusses how members can avoid and limit these risks through the
use of contract terms. The program also identifies provisions commonly contained in client generated
agreements that should be carefully avoided.
The second segment of the program concentrates on non-legal skills and techniques that can help
members avoid litigation. This portion of program discusses problem solving; how to determine when a
problem is escalating into a dispute; what to do if you find yourself with a full blown dispute on your hands;
when to settle; and how to conduct effective settlement negotiations.
The final segment of the program focuses on the kinds of documents members should always maintain, and
the kinds of documents they should never generate; briefly describes what members can expect in litigation;
and concludes with tips on how to survive the stress of a lawsuit.

(NOTE: The first topic is a meeting presentation; the second topic is a 4-5 hour educational seminar)
Fun with the Invisible Substance Water Vapour – Myths, Puzzles and Fundamentals for a Lifetime (Several
puzzles deal with surface mold and mold behind vinyl wall covering)
This 45-minute talk is structured for any combination of ASHRAE members, spouses, architects, home
builders and residential air conditioning contractors. “Fun” implies that the talk involves the audience with
the moisture myths and puzzles each of us encounter in our homes and buildings. Most of the audience will
leave with a far better understanding of the elusive substance called water vapour or humidity. Since
moisture is the single controllable variable in preventing mold, three of the “puzzles” will provide practical
and positive means of avoiding mold. Skeptics may leave with doubts, but they may think twice the next
time they encounter a humidity problem or moisture mystery and consider a technique based on a myth as
a solution. Water vapour makes no distinction between your home or a commercial-industrial building and
many of the solutions are presented in terms of your home and its IAQ – topics that effect the long-term
health of your spouse and children.
Psychrometrics – From Forgotten Fundamentals to Practical Application
This four-hour course is structured as a chapter educational seminar. It requires one or two breaks and thus
the total length is approximately five hours. This course does not overlap the 45 minute talk and for
economy could be presented on the same day as the 45 minute talk. Attendees should leave with a lifetime
understanding of underlying fundamentals (which are rarely taught); full knowledge of the equations used in
psychrometrics, accuracy and limits of the equations, accuracy limits (and hidden assumptions) of the
constants used in simplified air quantity and other HVAC equations; all psychrometric processes; FAQs and
error avoidance. Course material is the 317 page Psychrometric Handbook.
A beta test of this course was used by the Atlanta Chapter with proceeds to the chapter’s annual
contribution to ASHRAE research. The instructor’s fee, other than the cost of the handbooks, is waived
provided that the proceeds go to the sponsoring chapter’s research contribution. Handbooks ($89 per
attendee) for the course are provided to the sponsoring chapter at a 15% discount ($75 chapter cost).
Suggested attendee fee for this course is in the range of $195 to $295+ with net
proceeds to the chapter. Course outline is available by contacting the author. It is suggested that this
course be underwritten by guaranteed attendance commitments from local and regional consulting
engineers, design build-contractors, manufacturers, etc. Because of the cost and time commitment, this
course is probably not attractive to members of a local student chapter. It may be attractive to those
students and graduate students committed to a career in air conditioning, meteorology, drying,
dehumidification and some agricultural engineering students. It is suggested that individual local chapter
members underwrite expenses for students wishing to attend.

Air Conditioning: A look Into the Past and a Guess Into the Future
Starting with a brief historical review, and some of the trends in research, predictions are made as to what
the future might be in air conditioning for human comfort. The presentation could be considered “technically
entertaining.” Suggesting the fallacies of predictions, it shows the historical delays from defining a concept
to the marketing of an actual product. The implications to our industry are noted as well.
Thirty Years of Research in HVAC&R
An overview is given of thirty years of research conducted by students under the speaker’s tutelage. Major
successes and failures are pointed out. The dynamics of effective industry-sponsored research in academic
institutions are noted, challenging some of the current paradigms. The presentation will identify those areas
where further research could be needed, and also suggest some where research should not be a high
Releasing Individuals’ Own Creativity
Growth requires change; change is aided by new ideas; and new ideas require creativity. The potential to
be creative is within all of us. The lecture is intended as a means for individuals to attempt to realize their
own potential to be creative. Theories of creativity, blocks to creativity, and exercises to develop creativity
are presented. Examples of engineering students awakening their creativity will be presented. These will
be from a decade of facilitating a course on engineering creativity. To the extent possible, the lecture will
include some audience participation.
Differing Perspectives Into Ozone Depletion and Global Warming
This lecture is intended to provide a different perspective to the usual formal presentation on these topics. It
was the consequence of attempting to analyze the available data to demonstrate the reality of ozone
depletion and global warming. Unfortunately, the analysis led to the conclusion that the only reality is in the
uncertainties in these areas. Data demonstrating the ozone depletion and global warming trends are
summarized and the common understanding of terminology such as ODP and GWP is presented. The
lecture ends with a listing of assumptions and aspects of the data that could raise questions as to the validity
of the implied trends.
Active Listening and Styles of Communication
Role playing by the audience will assist in visualizing aspects of adverse responses. This will set the stage
to define and exercise active listening techniques. Active or empathetic listening is essential to effective
communication and group dynamics.
Principles of Leadership and Group Dynamics
Effective leadership is essential in ASHRAE committee work. The distinctions between management and
leadership are brought forth, together with major concepts defining effective leadership. Concepts of group
dynamics, including non-verbal communication styles are also presented.

I Learned About HVAC&R From That
This talk is a collection of recollections of the problems found in building systems construction and
operation, with a summary of lessons learned from each. Lecture topics may be selected from a list which
includes about 30 topics each, requiring about five to seven minutes to discuss. The topics are written in a
somewhat humorous vein and make the program suitable for presentation during lunch. The subjects range
from failure of engineers to observe proper testing procedures, failure of the contractor to keep a copy of the
Project Manual in the field, test and balance agency misdeeds during the early days of T&B, failure of
building operation and service technicians to follow proper operating procedures, and problems with
pneumatic control system air piping.

Technical Communications for the Practicing Professional
Practicing engineers and technologists have a solid foundation of technical skills as a result of their
academic education and job experiences. However their ability to communicate this knowledge to their
peers, clients, employers, general public and even politicians is critical to their success as professionals.
The importance of communication skills, including listening, and techniques for conveying a technical
message regardless of the audience will be presented.
Engineering Your Future
It is important that engineers and technologists are as deliberate about engineering their career as they
are in engineering building systems and equipment. Active participation in technical societies such as
ASHRAE helps in this design process. You will learn about specific opportunities for professional growth
through ASHRAE involvement and how that participation will contribute toward the engineering of your
Designing for Comfort
"Thermal Comfort: That condition of mind that expresses satisfaction with the thermal environment."
Fortunately, there is more guidance that ASHRAE provides in the design of environmental control
systems than merely a definition. ASHRAE and others have conducted extensive research to determine
conditions necessary to maintain thermal comfort. Within these conditions, engineers have considerable
latitude in the design of their systems. It is critical that engineers understand the variables affecting
comfort, the interaction of these variables and how they can be incorporated in system design to maintain
comfort at the least energy expense.
The Energy Design Process for High Performance Buildings
NOTE: (Primarily suitable for technical session of approximately 15 minutes)
Successfully designing, constructing and operating high-performance buildings requires a team approach
from the very inception of the design process. Ideally the team would include the building owner and
operator, building designers, equipment suppliers and contractors. Regardless of the composition of the
team, the design process is critical. This presentation will give details of a process that focuses on
energy efficiency. Actual high-performance buildings which have been designed using the suggested
process will be shown as examples.
The Future of the HVAC&R Industry
Our industry has had a profound effect on humanity throughout the globe. Occupants in our buildings are
more comfortable, healthier and productive. Food can be transported throughout the world and industrial
processes have been made possible because of our technology. These improvements have been
brought on by both advances in technology, market changes, societal concerns for our environment and
political decisions. Regardless of the reasons for this change, we must be prepared to direct those
changes for the betterment of our clients and our industry. This presentation will discuss new advances
in technology, market trends and global standards affecting the use of our systems and equipment and
how you can have a positive effect on the future of our industry.

Designing for Occupant Acceptance
In order to meet the increased expectations of building occupants, designers must be aware of the
conflicts between cost economics, occupant productivity and life cycle costs. Buildings that do not meet
the needs of the occupants often result in expensive redesign, or worse, result in lawsuits against all
parties involved. Recent court cases make it imperative designers understand the changing 'rules' of the

In order to meet the increased expectations of building occupants, designers must be aware of the
conflicts between cost economics, occupant productivity and life cycle costs. Cost savings measures
have resulted in severe building problems, including deaths due to Legionnaire’s disease, and often
energy consumption increases. Buildings that do not meet the needs of the occupants often result in
expensive redesign, or worse, result in lawsuits against all parties involved. Recent court cases make it
imperative that designers understand the changing 'rules' of the road. Building owner’s need to
understand how their building systems work, to avoid creating problems in a tightening economy.

Selecting VAV for Acceptable IAQ
In order to meet the increased expectations of building occupants, designers must be aware of the
conflicts between cost economics, occupant productivity and life cycle costs. Buildings that do not meet
the needs of the occupants often result in expensive redesign, or worse, result in lawsuits against all
parties involved. Recent court cases make it imperative that designers understand the changing 'rules' of
the road. Recent Specifications for VAV components are often flawed, and meeting the specification will
result in unacceptable spaces, and poor IAQ.
With the large number and types of VAV terminals available on the market, we are getting a number of
questions regarding the proper selection and interpretation of VAV terminal specifications. This talk will
cover proper engineering specifications and designs for this broad product range, with updates on the
latest rules and knowledge regarding VAV box type, linings, accessories and air flow limitations.

distribution systems. He is an annual visiting lecturer at the University of Wisconsin’s “Boiler Plant Design

on waterhammer accidents, steam safety, and chilled water design are available at www.kirsner.org.
Understanding Steam Condensation Induced Waterhammer
This is the type of waterhammer that kills people. Its initiating mechanism is much different than the image
most engineers have of what causes waterhammer – i.e., fast moving steam picking up a slug of
condensate and hurling it downstream against an elbow or a valve. Because it does not require flowing
steam, it often occurs during relatively quiescent periods when operators least expect it. Operators and
engineers need to understand this type of waterhammer so they can avoid procedures which can initiate it,
and designs that are susceptible to it.
3 GPM/TON Condenser Water Flow Wastes Energy, Right? Wrong!
Generalizations can be helpful when they are accurate and broadly applicable, but they can also be
misleading when they reach too far. One such generalization put forward in the last several years is that the
ARI standard of 3 gpm/ton condenser water flow rate for water-cooled chillers is too high. It is suggested,
depending on the source, that the optimum condenser water flow rate per ton is actually 2 gpm, 1.5 gpm, or
even the minimum flow recommended by the chiller manufacturer. Fortunately, the accuracy and generality
of this assertion can easily be tested using simple thermodynamic principles. This talk will look at how the
theoretical power requirements of each of the three equipment elements change if the condenser flow rate
is reduced from 3 to 2 gpm/ton in an effort to prove, or disprove, the assertion above.
The Demise of the Primary-Secondary Pumping Paradigm for Chilled Water Plant Design
The problem with the primary-secondary design of chilled water systems is that it cannot deal effectively
with “Low Delta Central Plant Syndrome.” Low Delta T is the condition whereby anemically low CHR
temperature causes excessive chilled water to circulate to meet system cooling loads, and chillers receiving
the low CHR temperature cannot be loaded to their design capacity. Virtually every large system suffers
from this syndrome to one degree or another. It is especially problematic in primary-secondary systems
where excess secondary CHR flows through the crossover-decoupler pipe dilutes the temperature of CHS
going out to the system. Mr. Kirsner believes that design engineers need to recognize the epidemic nature
of this problem and begin to view it as a design problem, not as a maintenance or operator problem.
The Causes of Low Differential Temperature Syndrome in Chilled Water Systems
Are all chilled water plants doomed to one day suffer from Low Differential Temperature Syndrome? Is it as
inevitable as old age? In previous articles written by Mr. Kirsner on chilled water design for HPAC
Magazine, he has advocated that engineers accept the fact that low differential temperature is present in
virtually all older central plant chilled water designs and engineers should begin to design chilled water
plants that are flexible enough to deal with it if it becomes a problem.
Designing for low differential temperature at the central plant generally means abandoning certain sacred
cows – like traditional primary-secondary pumping. Those who disagree with this approach argue – “Why
put a band-aid on the central plant instead of fixing the problem out in the system, especially in light of the
complication the band-aid approach is likely to cause to an otherwise simple central plant design.” The crux
of the differing views in this debate lies in each side’s apprehension of the key issue “How well do we
understand what actually causes low differential temperature, and how easy is it to eliminate?” This
presentation discusses the underlying causes of low differential temperature so we can begin to understand
why it is so widespread, and whether or not it can be eliminated from older systems.

How to Pre-Condition Outside Air to Ensure Good IAQ
ASHRAE Standard 62 – 1989 and now 62 - 1999 has substantially increased the amount of ventilation air
requirements in residential, commercial and institutional facilities. This was done to improve IAQ through
the dilution of contaminants produced in the occupied space. Unfortunately the increased amount of
outside air has in many cases reduced the IAQ. The reason is that in humid climates, standard HVAC
equipment is not able to remove the additional moisture. In many cases the moisture build-up in the
buildings has caused biological contaminates to breed. This condition has caused illnesses in the
This talk discusses 18 different ways to pre-condition the outside air before it is released in the occupied
zones or into the standard HVAC equipment. Many of these methods control the humidity of this air as
well as the temperature.

Thermal Insulation Systems in Buildings vs. the HVAC System
Unless the thermal envelope (i.e. the insulation-vapor barrier system) is carefully designed and installed it
may have a major negative impact on the HVAC system. Airflow through the thermal envelope can reduce
the insulation system R-value to near zero. A classic example of this is an acoustical ceiling with insulation
batts on top of the tile and a pressure difference across the ceiling. Another example is the HVAC designer
using a pressure difference across the thermal envelope in an attempt to control moisture issues. Insulation
failure can result in ice dams in northern climates and moisture condensation in hot humid climates and cold
climates. I have seen many so-called HVAC failures that were actually insulation system failures. Vapor
barriers/retarders are a very important aspect contributing to the performance of the HVAC system. A vapor
barrier is not a vapor barrier if it allows air transfer.
Moisture Problems in Buildings
Moisture problems are the most common problems in buildings. Excessive moisture or uncontrolled
moisture is a component of many IAQ problems. It is much less expensive to prevent moisture issues
than it is to correct the problems after they occur. The first step in the solution of a moisture failure is
external (rain or ground water leakage) or internal (condensation). Many buildings have a combination of
both sources. Humidified buildings (residential, commercial and industrial) have unique solutions. Indoor
pool buildings and trash-to-energy plans are two types of structures that frequently have condensation
stains, rot and corrosion resulting in lawsuits. Buildings in hot-humid climates such as the U.S. Gulf
Coast are just as likely to have mold and mildew as in buildings along the Canadian border. Is the HVAC
system a part of the problem or a part of the solution? I have seen both.
Pipe Insulation Liability on Underground Piping
Thermal insulation is quite vulnerable to expensive failure on underground piping. These failures are the
result of water entering and destroying the insulation system. The HVAC designer frequently does not
have adequate ground water level studies prior to specifying a system. Ground water level (year round)
is the single most important issue in choosing an underground insulation/conduit system. Manufactures
of insulation systems for underground pipes do not adequately provide design engineers or contractors
with the benefit of the many lawsuits that have shown weaknesses in their products and their application.

Chilled Water System Forensics
The topic of low return water temperature in chilled water systems is very complex. It can be related to
the classic “chicken and the egg” story, which came first?
Low return water temperatures do exist in some HVAC systems. Is it because of the type of system
design? Is it because of the way the system is designed? Is it because of the equipment selected for the
system? Is it because of the way the system is installed? Is it because of the way the system is
operated? Is it because of the way the system is maintained?
The answer is any one of the above reasons, several of the above reasons, or all of the above reasons.
So before we get into the forensics of curing an existing system with low return water temperature, let’s
review the proper design techniques for modern chilled water system. Proper design, up-front, alleviates
the need to treat symptoms later on.
Getting the Least Operating Cost Out of Your Pumping System
When faced with the task of designing an HVAC pumping system, the engineer has many factors to
consider….present load versus future load; pipe corrosion; dual usage; hot water and chilled water;
accurate pressure drop data; piping installation; and safety factor, among others. The result is usually the
selection of a pump that is over-sized (over-headed) for the application. During this session, we discuss
the steps that need to be taken to minimize pump over-sizing; the operational, maintenance and financial
impact of pump over-sizing; and what to do with your over-sized pump.
Modern HVAC Pumping Systems
Moving fluids from the production source to the load and back is a significant portion of the HVAC
engineer’s design task. No one pumping method is the best for all applications. During this session we
review the reasons for utilizing variable volume pumping, discuss design criteria and the advantages and
disadvantages of each of the five types of variable volume piping systems:

Professor of Architectural Engineering
Pennsylvania State University
University Park, PA
Dr. Stanley Mumma is currently a Professor of Architectural Engineering at Pennsylvania State University.
Prior to joining Penn State in 1984, he was a General Motors Corporation project engineer for 3 years
between his undergraduate studies in Mechanical Engineering at the University of Cincinnati, and his
graduate work at the University of Illinois at Urbana-Champaign. Since earning his Ph.D. in Mechanical
Engineering in 1974, under the mentorship of Dr. Will Stoecker, he has also held faculty positions at Ohio
State University and Arizona State University. In the first half of his academic career, his research
focused principally on solar and alternate energy. Then his interests changed to innovative ways of
meeting ASHRAE Standard 62 in an energy efficient fashion. That work has led to his current intense
interest in dedicated outdoor air systems (DOAS). In the year 2001 alone, he published 14 papers on the
subject and that number continues to grow. During his career, he has 71 peer reviewed publications and
57 other publications. Two of those publications were recipients of ASHRAE best paper awards. He has
also received ASHRAE’s Distinguished Service Award, the E.K. Campbell Award of Merit, and the grade
of Fellow. Currently Dr. Mumma is a Board-appointed trustee of the ASHRAE Learning Institute.
Dedicated Outdoor Air Systems (DOAS)
Dr. Mumma will present his view of DOAS, including in depth psychrometric analysis. Then he will
discuss why he is convinced engineers are seriously considering them. The reasons are based primarily
upon the following six propositions:
1. Ventilation air distribution uncertainty in all air VAV systems. Engineers cannot be sure
where the ventilation air, in all air systems, is distributed once brought into the building and mixed
with return air at the air-handling unit. Therefore engineers cannot really defend compliance with
ASHRAE Standard 62-1999 when using all air VAV systems.
2. Excess OA flow and conditioning required for all air VAV systems. When the multiple
spaces equation of ASHRAE Standard 62-1999 is used, generally from 20-70% more outdoor air
is required in an effort to assure proper ventilation air distribution in all air systems than is
required with a dedicated outdoor air system.
3. VAV box minimum settings must be suprisingly high. Perhaps contrary to current practice,
VAV box minimums must reflect both the ventilation requirements of the space and the fraction of
ventilation air in the supply air. When the box minimums are properly set to satisfy the ventilation
requirements, the potential for considerable terminal reheat becomes an issue.
4. Inability of most all air VAV systems as currently designed to decouple the space sensible
and latent loads and to provide adequate environmental safety. This leads to potential IAQ
problems and sick-building illnesses, not to mention the terrorist threat. The Lawrence Berkeley
National Laboratory estimates that U.S. companies spend as mush as $58 billion annually to
cover medical expenses and $200 billion annually in lost productivity as a result of sick-building
5. Significant first and operating cost savings can be realized when the DOAS employs total
energy recovery as required by ASHRAE Standard 90.1-1999. This will be contrasted with all-
air VAV systems that employ demand controlled ventilation.
6. Ceiling radiant cooling may be the optimum parallel sensible cooling approach to use with
the DOAS. Common concerns on condensation, capacity, cost, and comfort will be dismissed.
And the green building LEED rating point potential of the DOAS/cooling panel approach will be
very briefly explored.

published approximately 200 papers.
The Possibilities and Limitations of Water Based Radiant Heating and Cooling Systems
The demand for comfort, better insulation of buildings, and increased internal loads from people and
equipment has increased interest in installing a cooling system to keep indoor temperatures within the
comfort range. Due to the use of energy, high costs, problems with IAQ, draught and noise, it is in
several countries often debated if full air-conditioning of buildings is recommended. Alternatively, heating
and cooling may be done by water based radiant heating and cooling systems, where pipes are
embedded in the building structure (floors, ceilings, walls) or in the center of the concrete slabs between
each story. Activating the building mass will not only give a direct heating-cooling effect, but also, due to
the thermal mass, reduce the peak load and transfer some of the load to outside the period of occupancy.
Because these systems for cooling operate at water temperature close to room temperature, they
increase the efficiency of heat pumps, ground heat exchangers and other systems using renewable
energy sources. The lecture will discuss the possibilities and limitations of water-based radiant heating
and cooling systems. Performance regarding comfort and energy will be presented and discussed based
on computer simulations, measurements in test rooms and measured performance in existing buildings.
International Standards for the Thermal Environment, Indoor Air Quality and Ventilation
The main purpose of most buildings and installed heating and air conditioning systems is to provide an
indoor environment that is acceptable and does not impair health and performance of the occupant.
Today most people spend more than 90% of their time during work, at home, during transportation or
leisure time in an artificial indoor environment created by man. Buildings and installations should
therefore be designed, installed and operated so that a substantial majority of users during the time of
occupancy can achieve a healthy and acceptable indoor climate. The
knowledge on the thermal climate parameters (air temperature, operative temperature, air velocity,
humidity, clothing, etc), their influence on the occupants and the influence of buildings and systems on
these parameters are today relatively well know and established in international standards. The
knowledge on indoor air quality (ventilation, bioeffluents, tobacco smoke, humidity, emissions from
building materials and HVAC systems) has during the last decade increased and several standards are
now published or are being prepared. This lecture will give criteria for design and evaluation based on
existing international standards or standards in progress.

Indoor Air Quality
ASHRAE Standard 62 provides designers, owners and facilities operators a standard for designing
ventilation and acceptable indoor air quality. This lecture traces the history and development of Standard
62 to the present including the continuous maintenance process to change the standard. In addition, a
comprehensive analysis with examples on using standard 62 is presented. Examples include traditional
outside air ventilation systems, more advanced systems such as desiccant dehumidification, integrated
systems and advanced air cleaning devices.
The consumption of energy within buildings goes far beyond the traditional design of the building. This
lecture provides designers, owners and facilities operators a team approach to managing energy within
their facility. The approach starts with the design options available to reduce energy consumption. A life
cycle cost analysis is used to qualify energy reduction measures and practical examples are provided. In
addition, options are presented to measure and monitor the buildings energy usage and compare these to
multiple building sites and usage dates.
Indoor air quality and energy reductions in buildings have combined to present a challenge to designers,
owners and facilities operators in achieving both. This lecture addresses the opportunities in using
desiccant dehumidification to achieve dry indoor conditions in humid climates while reducing the energy
consumption of air conditioning. An overview of the desiccant process is provided including
fundamentals, types of desiccants, components of desiccant systems and practical design examples. In
addition, the most recent research and development on an integrated desiccant/vapor compression
system is presented.
Moisture in and Around Buildings, a Recipe for Disaster
In hot and humid climates, engineers, designers, contractors and owners face mounting challenges
controlling moisture in buildings. Sometimes the issues involve other building systems that the HVAC
professional has no control over. However, when the mold, mildew and fungus start to infest the building,
the HVAC professional is the first to be blamed.
The HVAC professional is also challenged with continuing research and design developments that lend
insight to the design strategy. ASHRAE research, through its technical committees and task groups has
advanced the arts and sciences of this special area of interest.

Worst Practice Lessons for Future Quality
This talk will review problems in the construction process that have led to litigation or arbitration. There
are many opportunities in construction for conflict. Troubles are based on technical and procedural
problems, both of which are a result of human failings. Triggers for a dispute are remarkably similar
project to project. Many problems result from an inability to design and manage the interface between
activities even though each activity is carried out in accordance with good practice. Quality management
solves problems of how well a particular piece of work is done, but may not address the way in which
groups work together.
History of Maintenance and Looking to the Future: The Divergence of Building Services Design from
Maintenance in 1950 to its Convergence in 2020
Tracing the commonality of design, construction and maintenance, from the code of Hammerabi in 2000
BC through Victorian engineering to World War II, shows common trade based skills. The foundation and
early years of ASHVE fit neatly into this history. The Second World War led to refinement of technological
design. Post-war changes in the education and training of engineers separated the scientifically based
design practice from the trade based maintenance and construction practice. In the building industry at
the present time, there is a lack of understanding and trust between the designer and the maintainer
which has caused, or is the result of, problem buildings and in particular Sick Buildings Syndrome.
Contemporary lessons from manufacturing, and in particular aircraft manufacturing industries indicate that
computer based design, diagnostics and simulation will draw the strands of design and maintenance
together, before 2050, and possibly by 2020.
The convergence will be successful only if ASHRAE members acknowledge the need and show technical
and cultural leadership. This talk will describe actions that must be taken and practices followed by the
Quality of the Internal Workplace and Worker Productivity: A Look Beyond Engineering
This talk is in three parts: the work of the HVAC Engineer, definitions of productivity, and other aspects.
The HVAC Engineer who refers to the ASHRAE standards and applies knowledge and wisdom contained
in the ASHRAE Handbooks has solved a major part of the problems of indoor air conditioning. The talk
will review the current knowledge base and consider related technical aspects of lighting and architectural
As comfort is perceived as a state of well being, productivity is usually taken as a perception of efficiency.
Work in this area has mainly addressed the perception of productivity, but others rely on measurement
including keyboard accuracy and speed. Aspects of productivity are the business of the HVAC engineer.
In parallel with developments in the HVAC and comfort aspects of indoor air quality, there is a large body
of alternative knowledge. The talk will review this, ranging from the philosophy of work and management
technique through the application of fung shui and other behavioral guides. The electronic smog
generated by the increasing use of computers, power lines and mobile phones will be presented. The
influence of earth energies and their interruption by electric and magnetic energy will be described. A
view will be presented for discussion on whether and to what extent the HVAC engineer is challenged in
their design by this alternative research.

filtration. This discussion will help ASHRAE members better understand the new standard and how to
What’s in the Air? Solutions for Indoor Environments in New and Existing Buildings
Particulate matter indoors provides an environment that is not conducive to building inhabitant
productivity and may possibly have adverse health effects. This discussion identifies contaminants in the
indoor environment with suggested ways to remove them through filtration.
Air Filters 101 – A Short Course in the Principles and Applications of Low, Medium and High Efficiency Air
Air filtration is a misunderstood science for most people. This discussion focuses on how a filter “filters,”
the different efficiencies of filters, and how to identify which filter best fits the application and need of a

RONALD J. WILKINSON, P.E.
Montana Division of Architecture and Engineering
Ronald J. Wilkinson is responsible for managing the State of Montana’s building commissioning program.
He earned his BSMAE from the Illinois Institute of Technology in Chicago in 1971 and his MPA from The
Evergreen State College in Olympia, Washington in 1985. He is a licensed mechanical engineer in the
states of Washington and Montana, with 30 years of engineering experience in commercial, industrial and
institutional facilities design.
Mr. Wilkinson was Secretary, Treasurer and Vice Chair of the Seattle Chapter of the American Society of
Mechanical Engineers from 1978-1982, has been a member of ASHRAE since 1982 and is currently a
member of the Building Commissioning Association. He is a recipient of the Environmental Protection
Agency’s Environmental Excellence Award, the Montana Governor’s Award for Excellence and is an
ASHRAE Research Investor. He is a Vice President at Large and C0-Chair of the Commissioning
Guidelines Committee for the National Association of State Facilities Administrators (NASFA) and a
member of the HPAC Magazine Editorial Board.
Mr. Wilkinson is a national author and speaker on the topics of commissioning and environmental control
systems. He has written for most major publications in the field of facilities design and energy
conservation, including the ASHRAE Journal, and is the author of the “Best Practices in Commissioning”
handbook published by the Northwest Energy Efficiency Alliance. He has been invited speaker at the
National Conferences on Building Commissioning since 1998 and will lecture and provide workshops at
the 2002 conference in Chicago.
Building commissioning is quality assurance applied to building construction. Integrated commissioning
begins in the planning stage of a new building and continues through construction and the first year of
occupancy. It includes documentation of the design intent, plans checking, inspection, testing, O&M
training and monitoring and is multi-disciplined, employing a team of engineers, control and air balance
technicians. Mr. Wilkinson’s programs are based on ASHRAE Guideline 1-1996, wherein the
commissioning program is coordinated by an independent third party commissioning authority.
Mr. Wilkinson offers seven commissioning programs. The programs range from a general overview to
more detailed treatments of commissioning project management. Program times are from one to six
hours and include lectures as well as group exercises. The shorter programs of a general overview and
current events are appropriate for luncheon or dinner meetings. The more in-depth programs are
intended for a classroom/workshop environment. All programs are in PowerPoint format and include
annotated workbooks for all participants.

Central Chiller Plants Turn Up Gold
Energy consumption of chiller plants often goes unchecked. This area has literally been a gold mine of
conservation opportunities for 99% of the chiller plants visited. Starting with the pumping system, what
pressure differential is there? What is needed in the buildings or air handlers served? What about the
devices absorbing the pressure differential? Are they needed or is there another way to accomplish the
goal? Is there a balance between the required flow and the pumps installed? Is it a constant speed
primary-secondary, a variable primary, or a constant primary-variable secondary pumping system? If it is
variable speed pumping, what controls the speed of the pumps?
How about the control system? Are the pumps controlled as one element of an integrated control system,
one that reads the needs of the devices served to determine the pump speed and pressure differential?
Can the operator easily diagnose the total plant operation with the control system central station? In case
of an emergency, can one dial in and look at all systems from a laptop from off-site? Are the flow
readouts reliable? Does the control system integrate directly with the chiller control system?
Want to talk about control systems? Come to the meeting and do just that.
"Virtual" Central Chiller Plant
Did you know that you can tie all those building chillers and pumping systems together, without adding
pumps, to serve the entire campus cooling needs? Whether an office complex, an industrial complex, or
a university campus, the entire cooling load can be met by the chiller(s) within any building connected to
the loop. This permits only one chiller to supply the cooling needs of all the operating building systems
during light load conditions. As the load increases, another chiller system is added. Energy savings will
normally repay the cost of installing the piping system within a very reasonable time.
What are the concerns? How can those concerns be addressed? Does it really work? Isn't this contrary
to all we've learned for years about chiller plants and campus distribution systems? Is there variable
water flow in the chiller? How can the system be balanced? Does it need to be balanced? How can it be
controlled effectively? Does it require a full time control system operator? These questions can be
addressed at the meeting.
Automatic Controls can reduce the energy consumption of old or new double duct systems, without the
expense of converting them to VAV and at a much lower cost. The preprogramming work is an important
issue to address. How can we save energy with a double duct system? What do you mean, install a
VFD on a constant volume system? What does a constant volume-variable pressure system look like?
How can the system be controlled? Attend the meeting and ask those questions.
