Go Green

KOCHI: Incorporating energy-efficiency measures in buildings has the potential to save up to 50 per cent energy, since buildings are responsible for 40 per cent of the total greenhouse gas emissions.

For existing buildings, the savings potential through alterations and energy-efficient fittings is between 20 and 25 per cent. Even non air-conditioned buildings can go green, by making optimal use of wind and daylight and by adopting other environment-friendly measures. These were stated at ‘Go Green’ – a seminar-cum-exhibition on green buildings, organised here on Friday by the Rotary Club of Thripunithura and KREEPA, as part of their Akshaya Vikas Project.

Making a presentation, Siva Kishan, chief executive officer of GRIHA – Green Rating for Integrated Habitat Assessment (which is the national rating system for green buildings), said the Energy Conservation Building Code regulates the usage of power in new buildings. “Green-rating mechanisms have been able to sensitise the construction industry to the benefits of integrated design and resource efficiency, from both the economic and environmental perspective. A rating system for India must respond to the country’s diversity and help develop sensible solutions relevant to different building projects.”

In her presentation on ‘Green buildings – the potential to earn carbon credits,’ Mayurika Chakraborthy, senior consultant with Deloitte Touche Tohmatsu India, said that less power consumption for lighting, air-conditioning, etc., would mean lesser usage of electricity from the thermal-power dominated power grid. “This in turn means an equivalent reduction in the amount of greenhouse gases like carbon dioxide that are released from fossil fuels. This makes a green building eligible to earn carbon credits.”

Guruprakash Sastry, manager (Green Initiatives) of Infosys, said the IT firm has been aggressively going ahead with its plan to design all its buildings as green buildings, to optimise energy performance and occupant comfort. “Sustainable buildings and saving every percentage of electricity and water make business sense and reduces expenses, especially when the annual electricity bills exceed Rs.120 crore and the water consumption is over 3 billion litres.”

Quoting Winston Churchill, Sathiaram Ram of IGBC, Hyderabad, said, “We shape our buildings. Thereafter, they shape us.” Buildings consume more energy than industry and vehicles. The green concept must become part of society’s DNA. Even a 100-sq ft building can make a difference in shaping a better world. The intangible benefits of green buildings include better working/living atmosphere, he said and cited how a 20,000 sq ft green building saved Rs.9 lakh a year.

“India also has a great opportunity to export green-building technologies. Already, India has 508 green buildings spread over 358 million square ft area,” Mr. Ram said.



ISHRAEISHRAE, the “Indian Society of Heating, Refrigerating & Air-conditioning Engineers” was founded in 1981 in New Delhi by a group of eminent HVAC&R professionals. Between 1989 & 1993, ISHRAE Chapters were formed in all major cities in India and also in the Middle East. ISHRAE has grown rapidly and now has more than 3000 HVAC&R professionals as members in 11 chapters in India and abroad. The Delhi Chapter is the first and the oldest of the constituent chapters of ISHRAE and has about 700 members.

Organizing successful international and national exhibitions is one of ISHRAE’s major activities. Its primary objective is to further the arts and sciences of heating, refrigerating and air-conditioning. ISHRAE has successfully organized more than ten exhibitions out of which four have been in New Delhi.

ISHRAE is an associate of ASHRAE (American Society of Heating, Refrigerating and Air-conditioning Engineers). ISHRAE Foundation Trust was formed in 1995, mainly to consolidate the Society’s resources and to channel them towards projects necessary for achievement of Aims and Objectives, as listed below.

Aims and Objectives

  • Advancement in Heating, Refrigerating and Air-conditioning Engineering and related Sciences.
  • Education of interested persons in said sciences through lectures, demonstrations and publications.
  • Rendition of Career Guidance and Financial Assistance to students of said Sciences.
  • Encouragement of Scientific Research.
  • To establish facilities for testing, rating, certification of air-conditioning, refrigeration, and allied equipment and systems.
  • To offer consultancy services in the areas of Education and Training in said sciences.
  • To disseminate and make available to the Government, Industry, and General Public information relating to said sciences through papers, reports and periodic publications.

Priority Areas


ISHRAE has recognised that training technical personnel is the single most important need at present, to improve the quality of HVAC & R work and raise it to meet ever-increasing customer expectations. It has also been felt that the existing manpower needs continuing education to equip them with the latest technology. This has become particularly relevant in the wake of globalisation of the Indian economy. Several industry leaders have also strongly expressed the need for such training.

Testing, Rating & Certification of Equipment and Devices

The last few years have seen a surge in manufacturing of both – major equipment as well as ancillaries and devices in the HVAC&R Industry. This has given rise to a need for a facility which will undertake testing, and will develop ratings which will help the industry establish reliable ratings and encourage development work.

Advisory Council

In addition to the Board of Trustees, an Advisory Council consisting of eminent persons in the fields of Air-Conditioning, Refrigeration and Allied fields, are to be formed to deliberate on the activities of the foundation.

Sustainable Development

ISHRAEACREX INDIA 2010, which is Asia’s largest International Exhibition and Conference catering to Air Conditioning, Refrigeration, Ventilation & Building Services Industry is organised by ISHRAE, endorsed by ASHRAE and supported by the Indian Green Building Council, the Bureau of Energy Efficiency, and the Refrigeration & Air-conditioning Manufacturers Association amongst others.

ACREX INDIA 2010 was held at the Bombay Exhibition Centre from 17th – 20th February and brought together leading companies and technologies that focussed on energy efficiency, indoor air quality, and innovation in and products and services that are green and sustainable.

Highlights of the Exhibition:

  • Exhibitors showcased products that conform to the Energy Conservation Building Code, 2007 of the Bureau of Energy Efficiency
  • Solar Energy for Air-conditioning was featured by Mamata Energy of Ahmedabad
  • The Indian Green Building Council (CII organization) and the Bureau of Energy Efficiency (Govt. of India) were both supporting agencies that influence the development of the Industry and its products.
  • ASHRAE (The American Society, with 55 000  members) endorsed ACREX for the 1st time with an active contribution to Workshops, Seminars and overall Promotion
  • With substantial overseas participation, ACREX demonstrated India as a prime market for efficient products
  • The event was produced professionally by UBM, a leading International Media and Exhibition Company

Workshop for BEE Energy Star

A Half day workshop on “Workshop for BEE Energy Star Labelling and Energy Efficiency Improvement in Buildings‟ has been organised by ISHRAE.

BEE Star labelling program for buildings has recently been launched by Bureau of Energy Efficiency, New Delhi, for evaluating the energy performance of buildings. There was a provision of issuing “Energy star labels” to buildings as per their energy efficiency, similar to the energy star labels for home appliances (e.g. air-conditioners, tube-lights). Energy audit studies in buildings have shown large potential for energy savings both in government and commercial office buildings.
