Energy Audit and Management Masterclass

Dr. Lock is a Professor (Engineering) at the Singapore Institute of Technology (SIT) and the Head of its Energy Efficiency Technology Centre. He plays an active role in energy efficiency and sustainability, being the Chairman of Accreditation Committee for Energy Service Companies (ESCOs) and the Co-Chair of Steering Committee of Singapore Certified Energy Managers (SCEM) Scheme. He is an Accredited Tier Designer awarded by the Uptime Institute. He is a specialist consulting engineer in the areas of mission-critical electrical design, power quality, EMC, and safety. He conducted many power failure investigations of data centres.

Professor Lock has a unique blend of practicing and academic experience acquired through a career which is equally split between the industry and the academia. He received both his B.Sc. (1975) and Ph.D. (1979) degrees in Electrical Engineering from the University of Strathclyde, UK. He was a faculty at the Department of Electrical Engineering, National University of Singapore for 17 years when he left to set up his consulting practice in 1997. He returned to the academia as a professor at SIT in 2016 after 20 years in the industry.

He is a registered Professional Engineer (Electrical) and served as a Board Member of the Professional Engineers Board, Singapore for 14 years. He is a Fellow of Academy of Engineering Singapore and an Honorary Fellow of the ASEAN Federation of Engineering Organizations.

He is the co-Laureate of the 2021 WFEO Medal for Excellence in Engineering Education awarded by the World Federation of Engineering Organisations. He received the Public Service Medal (2015) and the Public Service Star (2020).

Dr Lal Jayamaha is the author of two books on energy efficiency titled “Energy Efficient Building Systems” and “Energy Efficient Industrial Systems”, both published by McGraw-Hill, USA and the founder of LJ Energy which is one of the leading ESCOs (Energy Service Companies) with offices in Singapore, Malaysia, Sri Lanka and Vietnam. 

He graduated from Queen Mary College, University of London with a First Class Honours degree in Mechanical Engineering in 1982. In 1990 he was awarded a Research Scholarship by the National University of Singapore to undertake research leading to a MEng degree. After completing his Master’s degree in 1993 he continued his research in heat transfer relating to building heat gain and building energy performance and was awarded a PhD. degree in 1997. 

After completing his PhD, he specialised in the area of Energy Management and has been the team leader for many major energy audits and energy retrofits carried out in the Asian region. 

He is an EEO Assessor, SCEM (Certified Energy Manager), LEED AP (Accredited Professional), Professional Engineer (PE), Chartered Engineer (UK), GBI Facilitator, Green Mark AAP, BCA Registered Energy Auditor, and GreenRE Accredited Professional. He is also a member of the Institution of Mechanical Engineers, UK and the American Society for Heating, Refrigerating and Air-conditioning Engineers (ASHRAE).

Dr Jahangeer is the founder of the Singapore-based accredited Energy Services Company (ESCO), Energy Conservation Specialists Singapore Pte Ltd providing consultancy services for mechanical and energy Systems including large-scale trigeneration systems, boilers, and compressed air systems. 

He is a registered Professional Engineer (Mechanical) with the Professional Engineer Board (PE Board) Singapore. Dr Jahangeer graduated with a Master of Science (M.Sc.) in Mechanical Engineering from the National University of Singapore in 1998. He was awarded a Research Scholarship by the National University of Singapore (NUS) in 1999 to undertake a research project on solar energy and was awarded a Master of Engineering (M.Eng.) degree in 2002. After completing his M.Eng. degree, he continued with research and teaching at NUS and his research on evaporatively-cooled condensers of air-conditioning systems led to the award of a PhD degree in 2013. 

Dr Jahangeer’s areas of specialisation include air-conditioning and mechanical ventilation systems, combined heat and power systems, steam technologies, steam turbines and boiler systems, compressed air system optimisation, building energy simulation and energy optimisation and energy efficient data centres. He has also authored chapters in several technical books and research papers in international peer-reviewed journals. Dr Jahangeer is a certified Energy Efficient Opportunity Assessor (EEOA, Industry) by the National Environment Agency (NEA), Singapore. He is also an SCEM (Singapore Certified Energy Manager) and a Certified Data Centre Professional. He is a Senior Member of the Institute of Engineers Singapore (IES) involved in many professional engineering activities in Singapore and the region. 

For the last 12 years, he has also been providing training for local and international practising engineers from the mechanical and energy services sector including the Singapore Certified Energy Manager (SCEM) professional candidates. He along with his former colleagues has already trained about two thousand industrial professionals as Singapore Certified Energy Managers (SCEMs) since the inception of the SCEM in 2009.
