NEWSLETTER CHAIR MESSAGE
ASHRAE Application
Dear ASHRAE Colleagues,
ASHRAE’s Leadership is composed of a Board of Directors, Executive Council, Member Council,
Technology Council, and Publication & Education Council. ASHRAE’s committee structure is the
mechanism that makes the society run. Through this structure, members formulate policies, develop
procedures, direct society activities and promote the society to be an Education & Learning Institute.
How ASHRAE society is a Learning Institute & Why?
ASHRAE writes standards and guidelines in its fields of expertise to guide the industry in the
delivery of goods and services to the public. ASHRAE standards and guidelines include
uniform methods of testing for rating purposes, description for recommended practices in
designing and installing equipment and other information to guide the industry. ASHRAE
has some 87 active standards and guidelines project committees, addressing such broad areas
as indoor air quality, thermal comfort, energy conservation in buildings, reducing refrigerant
emissions and the designation and safety classification of refrigerants.
ASHRAE supports the use of ASHRAE Standards and Handbook internationally through
translation.
ASHRAE publishes the ASHRAE Handbooks:
- Refrigeration
- HVAC Application
- HVAC Systems & Equipment
- Fundamentals
ASHRAE organizes technical Conferences.

ASHRAE conferences create the ideal atmosphere for those interested in enhancing the
building industry where it ensures and facilitates the development of a good network between
all members who inspect the latest technology and learn about the newest practices for the
built environment.
- Society Conferences
- Region Conferences
- Chapter Conferences
ASHRAE provides Chapter Technical Seminars
ASHRAE offers Distinguished Lecture – Program.
ASHRAE DLP provides ASHRAE Chapters, Student branches and other organizations with
lectures equipped to speak about relevant subjects of interest to ASHRAE members and
guests.

Technical papers are presented by the authors at ASHRAE Conferences. Technical papers are
submitted for review and they must be technically accurate and clearly written. Technical
Papers undergo a rigorous double-blind review and they must be approved by three reviewers
knowledgeable on the subject matter.
ASHRAE provides Webcasts.
These webcasts are displayed for industry experts who identified the link between energy
efficiency and indoor environmental quality (IEQ) through the integrated design process.
ASHRAE Certification Program
ASHRAE Offers:
- BEAR – Building Energy Assessment Professional Certificate

ARTICLE
IMPORTANCE OF SYSTEM EFFECT TO DETERMINE FAN CATALOGUE
PERFORMANCE AND AVOID DEFICIENT EFFICIENCY DURING TESTING &
COMMISSIONING
By
Mr. Mohamad Mokdad
Export Manager
Maico Gulf (Dynair & elicent)
Vice President
Ashrae-Qatar Oryx chapter
We always encounter deficient fan performance after installation, the first question comes in mind
“Proposed fan under sized or wrong Fan rpm” but practically it is just opposite, not always 100% but yes
90% cases are the same.
There is a terminology called “System Effect Factor”, as per AMCA 201-02, after calculating all ESP, we
should always check the system & the fan location, if 100% EDL (Effective duct length) not maintained
before & after the fan, we should add system effect factor (SEF) to the calculated system pressure losses
to determine the actual system loss, below one graph to show the actual deficiency.

Below one example with a plenum with & without EDL (From AMCA Publication 201-02):
D-E duct friction at 5000CMH (Q) 747 Pa (duct design)
D contraction loss-plenum to duct 50 Pa (part of duct system)
D PS energy required to create velocity at D 125 Pa (part of duct system)
B-C SEF 149 Pa
B-C PV loss (also P
T loss) at C as result of air velocity decrease 0 Pa
PS does not change from duct to plenum at C
------------------
REQUIRED Fan PS 1071 Pa

So what should be the rule of thumb?
• Minimum 2.5 duct diameters on Outlet
• Minimum 3 to 5 duct diameters on Inlet
• Avoid inlet swirl
• Allow enough space in the building design to allow for appropriate fan connections to the system
• Use allowances in the design calculations when space or other factors dictate less than optimum
arrangement of the fan outlet and inlet connections
• Include adequate allowance for the effect of all accessories and appurtenances on the
performance of the system and the fan

ASHRAE NEWS
NEW OPERATION TRAINING
New HVAC Design & Operation Training coming to Atlanta
ASHRAE is offering the new Improving Existing Building Operation training on August 18–19, 2016 at
Headquarters in Atlanta. This interactive course provides the fundamental and technical knowledge for
the proper operation and maintenance of existing HVAC systems to maximize building performance.
Learn the techniques needed to measure existing building performance to make commercial facilities
operate more efficiently and economically.
NEW ANSI ACCREDITATIONS
Three ASHRAE certifications have received accreditation from the American National Standards
Institute (ANSI), joining the High Performance Building Design Professional (HBDP) certification
that was accredited last year. Accreditation was approved May 23 for ASHRAE's Building Energy
Assessment Professional (BEAP), Building Energy Modeling Professional (BEMP) and
Commissioning Process Management Professional (CPMP) under International Organization for
Standardization (ISO)/ International Electro technical Commission (IEC) 17024:2012.
ASHRAE JOURNAL
Hospitals use two to three times more energy than other commercial buildings. Two articles in this
month’s issue tackle ventilation in hospitals. The first examines best practices for determining the
airflow path in patient rooms, and the second explores the evolution of health-care ventilation.
