Green building

Set to become an iconic building of Uttarakhand, first green building of ONGC was inaugurated at Dehradun by CMD Sudhir Vasudeva. The building has been named ‘Green Hills’ to highlight the environment-friendly and energy-efficient features built in its design and fabrication. It has a number of state-of-the-art ‘Green’ features like conservation of water upto 30 per cent through use of onsite sewage plant, rainwater harvesting, energy saving upto 43 per cent energy by use of energy efficient motors and under floor air conditioning. Besides this, solar power generation will meet 7.5 per cent of total electrical load.

It was a dream of the erstwhile CMD of ONGC late Subir Raha that ONGC should take the initiative to create green buildings as its prime location offices. Turning his dream into reality, five ONGC green buildings are coming up at Delhi, Mumbai, Kolkata and Hyderabad, apart from the one commissioned at Dehradun.

Some of the main features of Green Hills, ONGC Dehradun are:

• With a total built up area of 14600 sqm, the five storey icon can seat 620 persons.
• Registered with UNFCCC under clean development mechanism. It will generate 735 CERs every year.
• landscaped green roof and abundant bamboo plantation in the atrium of the building.
• Conserving water upto 30 per cent through use of onsite sewage plant and low flow sanitary fittings. Rainwater harvesting is also taken care at the building.
• Up to 43 per cent energy saving by use of energy efficient motors, High COP Chillers for HVAC and under floor air conditioning.
• Solar power generation will meet 7.5 per cent of total electrical load.
• Solar panels over parking spaces to generate energy and reduce heat by reflecting the sun light.
• Intelligent lighting for the building through use of sensors for day light control, lED and CFl lights and abundance of natural light availability.
