ISHRAE Institute of Excellence IIE Delhi organised two workshops in Delhi and Pune
Dear Friends,
Welcome to second edition of Twitter for
this Society year 2012-13 of DCI
(covering the period of July-Sep). Our Half
yearly performance has more or less been
on course with immense support from all
Office bearers, CWC and Extended
Committee members’ whole hearted
support. Some of the stand out activities undertaken during this
period are listed below :
• Student Activities in GB Pant & School of Planning and
Architecture
• K-12 Activity at Happy Model Public School
• DCI-IIE Workshops
o Fundamentals of applied Physchometry
o Duct Design & Air Distribution
o Building Information Modeling
o Integration of DG Set Security Fire Alarm and other
Building Services Ingreated BMS System
• Product Presentations
o Systemair – By Mr. Richard Bietmirza
o Sevcon-LTI – By Mr. Gaurav Vasudev
• Annual General Meeting was held with Audited Accounts of
previous financial year adopted and Nomination Committee
for next Society year was approved by members. ETA and
Schnieder made Corporate presentation of their respective
conglomerates.
• IIE/DCI entered into an agreement with CAD Studio to
undertake 40 hours 7 day course on Revit MEP training
course
This edition of Twitter covers an important topic of Commercial
Kitchen Ventilation. An adequately designed kitchen ventilation
system should achieve the following objectives.
• Remove cooking fumes at the source, i.e. as near to the
cooking equipment as possible.
• Remove excess hot air and introduce incoming cool clean
air so that a comfortable environment is achieved.
Inadequate ventilation can cause stress, contributing to
unsafe systems of work and high staff turnover.
• Ensure that the air movement in the kitchen does not cause
discomfort.
• Provide sufficient air for complete combustion at fired
appliances, and prevent the risk of carbon monoxide
accumulating.
• Be easy to clean, avoiding the build-up of fat residues and
blocked air inlets which lead to loss of efficiency and
increase risk of fire.
• Be quiet and vibration free.
With Season's Greetings and Best
Wishes for a very Happy New Year,
from the Twitter team.
Sunil Kher
President (2012-2013)
Workshop on BIMIt gives us immense pleasure to inform the readers
that under the patronage of Mr. Sunil Kher, a
workshop on BIM (Building Information Modeling)
was successfully conducted on 15th September’
2012 at India International Center, New Delhi.
Building Information Modeling (BIM) or Virtual
Design & Construction (VDC), as the name
suggests, is enabling the developers and other
stakeholders to reap the benefits of the technology subject and details presented by the guest speaker Mr. Parveen Sharma and avoid the project delays caused due to poor from M/s Intec Infocom (www.intecinfocom.com) were very informative design coordination. The BIM technology helps in and appreciated by the participants. Mr. Parveen Sharma is an Architect optimizing the designs and integrating with other with Masters Degrees in Computer Science and Computer Applications applications to extract intelligence for all participants (M. Sc & MCA). of a construction project.
The workshop was attended by Mr. Sunil Kher, Mr. Prabhat Goel, Mr. V K The workshop was attended by the participants Seth, Mr. Dhiraj Rastogi & Mr. Sunil Yadav. Mr Dhiraj Rastogi was the from various organizations (DLF, Fortis, Godrej, driving force behind the success of the workshop . Special thanks to Mr. Blue Cost Group, AECOM, Elumatech, etc.). The Sunil Kher and the DCI secretariat for making the workshop a success.
IIE Delhi has started its 14th batch in advance diploma
course in HVAC&R from 7th August 2012. We have very
bright students in the current batch. Companies looking

Competition for students of grade 2nd to 5th. 250 enthusiastic students
participated in the event. Staff & volunteers at the school were very
grateful & apprecitative of ISHRAE’S initiative.Mr Paryushan Jain and
Mr Arvind Kumar from DCI oversaw the event with the kind assistance of
the School principal Mrs Astha. Refreshments were given to all children
at the end of the program alongwith a certificate of participation.

The presentation was
carried out by Mr. Sunil
Kher and Mr. Ekansh Kshetrapal from M/s SEVCON. The
program was addressed by the National President Mr.
Sushil Choudhury and the DCI President Mr. Sunil Kher.
Also, present were the Student Activity Chair Mr. Dhiraj
Rastogi, DCI Secretariat Mr. Vikram & Mr. Arvind. Efforts
made by the faculty advisor Prof. V K Paul and DCI
secretariat ensured the success of the event.The
