Dr Prem C Jain
Chairman, IGBC


Dr. Prem C. Jain is famous for decades of service to the environment, earning him a reputation as a “green visionary.” He has a bachelor’s degree, a master’s degree and a doctorate in mechanical engineering, and upon returning to India in 1970 after post-graduate studies in the U.S., he served as a visiting professor at IIT Kanpur, where he taught post-graduate studies and set up a laboratory for environmental engineering. He has also been on the visiting faculty for the School of Planning and Architecture at Delhi University since 1973.

In addition to his academic accomplishments, he is a business entrepreneur, founding Spectral Services Consultants Private Limited (now an AECOM company) in 1980 with the mission of providing energy-efficient, fire safe, fully-coordinated Mechanical, Electrical, Plumbing (MEP) services design for all varieties of planned buildings in India. The firm grew from four employees to a staff of more than 600 in 10 offices

Dr. Jain has served as advisor to Her Excellency the President of India and to the Prime Minister of India; has chaired the International Green Building Congress in Chennai, Bangalore and Mumbai from 2006 to 2011; and since 2007, has chaired the Indian Green Building Council. He founded the Indian Society of Heating, Refrigerating and Air Conditioning Engineers in 1980, and the India Chapter of the American Society of Heating, Refrigerating and Air Conditioning Engineers in 1989. He also rewrote the section on air conditioning, heating and ventilation for the National Building Code of India-NBC 2005, bringing it up to the international level of codes, standards and practices.

The recipient of numerous awards and honors, Dr. Jain is listed in Marquis Who’s Who in Asia (Marquis, U.S.A., 2007) and Marquis Who’s Who in Science & Engineering (Marquis, U.S.A., 2000–present), as well as The Asia 500 Leaders for the New Century (Baron’s Who’s Who, U.S.A., 2000).


IGBC Rating System encouraging Net Zero Energy Buildings

Net Zero Energy Buildings (NZEB) are buildings which are net energy consumption and therefore result in zero carbon emissions. NZEB, energy should ideally reduce the overall demand of energy by adopting better building design and usage of highly efficient HVAC & lighting technologies. As the electrical demand is optimised the building would have renewable energy systems to meet the demand.
IGBC Green Building Rating System encourages passive architecture – which includes better orientation of the spaces based on the functionality, size and placement of openings. It also encourages appropriate selection of envelope design, coupled with regionally sourced and eco-friendly civil construction materials and energy-efficient HVAC and lighting equipment, systems & controls. By incorporating such strategies in the design stage itself, the energy savings potential would be about 40 to 50 %.
IGBC rated green buildings-through the use of passive interventions have demonstrated embracing India’s conventional wisdom and traditions. These buildings have widely used renewable energy sources such as, Solar PV, BIPV (Building Integrated Photo Voltaic), micro wind turbines, etc.,
By adopting IGBC Rating System, the following building have demonstrated exemplary performance. These buildings are not only meeting their own energy demands but also are generating net positive energy.

  • Bayer’s Eco Commercial Building, Greater Noida
  • Sun Carrier Omega, Bhopal
  • Gujarat Pollution Control Board, Gandhinagar
  • MoEF’s- Indira Paryavaran Bhawan, New Delhi



IGBC shall encourage many such innovative and futuristic green buildings which will go a long way in building a greener India.
