ABOUT THE SPEAKER AND THE TOPIC
CHANDRA SEKHAR, Ph.D.
Department of Building
National University of Singapore, Singapore
Dr. Chandra Sekhar is currently an Associate
Professor and Programme Director (M.Sc – Building
Science) in the Department of Building at the National
University of Singapore (NUS). He is also a Founding Director
of Enhanced Air Quality Pte Ltd., a NUS Spin-off Company
incorporated in June 2004, arising out of his research
in the fields of indoor air quality (IAQ) and Energy.
He has been an IAQ consultant in Singapore since 1993.
He received his PhD in Mechanical Engineering from the
University of Adelaide, Australia, and continued as a
postdoctoral fellow at the same university until 1991
where he worked towards the continued development of energy
efficient cooling and dehumidification systems. In 1992,
he joined NUS as a Faculty and has since been teaching
and conducting research in the areas of ventilation and
indoor air quality, air-conditioning and ventilation systems,
building energy analysis and has published about 150 papers
in these areas in several international journals and conferences. |

Dr. Sekhar is an editorial board member of Energy and Buildings
journal (Elsevier) and International Journal of Ventilation
and is a regular reviewer of articles for several international
journals, such as, ASHRAE HVAC&R Research Journal and Transactions;
Indoor Air; Energy and Buildings; Building and Environment;
Energy. He was the recipient of The Enterprise Challenge award
of the Prime Minister’s Office, Singapore in 2004. He
is actively involved in the development of local IAQ, ventilation
and energy standards in Singapore. He is a member of the International
Scientific Committee of the Healthy Buildings, Indoor Air, ROOMVENT
and IAQVEC series of conferences and was the Technical Co-Chair
and member of the organising committee of the Healthy Buildings
2003, the Seventh International Conference in Singapore in 2003.
In September 2005, Dr. Sekhar was elected as a Member of the
International Academy of Indoor Air Sciences (IAIAS). He is
an ASHRAE Fellow and member of International Society for Indoor
Air Quality and Climate (ISIAQ) and Institution of Engineers,
Australia (CPEng, IEAust). Within ASHRAE, he is currently a
member of Environmental Health Committee (EHC), SSPC 62.1, SSPC
55, TC 2.1 and TC 4.3 as well as the CTTC Chairman of ASHRAE
Singapore Chapter.
International Ventilation and IAQ Standards
Whilst research on ventilation and indoor air quality (IAQ)
is ongoing and a better understanding of the impact of ventilation
and IAQ on human comfort, health and productivity is continuously
evolving, it may be argued that it is difficult to agree upon
one international standard that is universally accepted. Most
existing Standards/Guidelines stipulate criteria or requirements
that are given as ventilation rates. However, some of these
standards also include more than one procedure to address the
issue of acceptable IAQ.
• Prescriptive Method : Minimum ventilation rates can
be found in a table listing values for different types of space
• Analytical Method : Calculation of required ventilation
rate on the basis of pollutant type, emission rates and acceptable
concentration
All current and proposed Standards aim to deal with both HEALTH
and COMFORT issues. This talk is an attempt to review some of
the current international efforts in the development and review
of ventilation and IAQ standards, such as ASHRAE, ISO and CEN
standards.
