 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 more than 100 papers in these areas in several international journals and conferences. Topic: Decoupled ventilation strategies for enhanced IAQ –
“Demand cooling” and “Demand ventilation” The concept of decoupling “ventilation air” from “supply air” is fast emerging as an ideal solution to combatthe problems associated with poor indoor air quality (IAQ). This talk will present the PersonalisedVentilation (PV) system and the Single Coil Twin Fan (SCTF) system, which show considerable promise intheir abilities to provide both good IAQ and energy efficiency. The PV system is fundamentally aimed atimproving ventilation in the immediate breathing zones of occupants in the built environment. The SCTFsystem is a new air-conditioning and air distribution system that improves occupants’ thermal comfort andindoor air quality whilst significantly saving energy. It provides “demand ventilation” and “demand cooling”by dynamically responding to the varying requirements in the individual occupied zones of a building.
