Mr Steven Kang worked as a Mechanical Engineer in Singapore's Public Works Department for more
than a year before joining Trane in 1996. A year later, he completed Trane's 6-month Graduate Training
Program at Trane's Headquarters in the USA. Steven Kang has varied experience in Trane ranging from
Unitary Sales, System Sales, Six Sigma and the design and energy optimization of HVAC systems. Steven
is a certified Six Sigma Black Belt (American Standard) and a certified Energy Manager (USA Associationof
Energy Engineers). He is a member of the American Society of Heating Refrigeration and Air-Conditioning
Engineering (ASHRAE) and a member of American Energy Engineers (AEE). He has spoken at various
forums on such topics as HVAC design, energy optimization and environmental issues.
mr Lee Eng Lock is a General Manager in Energy Division of Trane Singapore. He is a pioneer of super
efficient designs of cleanrooms, hotels, and office buildings. He routinely has designed electrical and
mechanical systems that use half the energy of standard buildings. He was responsible for optimising
the super efficient world headquarters, office/assembly complex of Compaq Computer in Houston,
Texas. He has given workshops on energy efficient wafer fabs and clean rooms in Portland, Oregon,
for leading semiconductor companies in Japan, Taiwan and USA; and lectures and gives seminars on
measurement, data visualisation and energy efficiency for utilities, national research labs, universities,
and government agencies in the USA.Target Audience
