India Applies Green Building Extensively

NAGPUR: Looking at the reality boom in the city, the Visvesvaraya National Institute of Technology(VNIT) has been making conscious efforts to promote the concept of green buildings among public as well the people and agencies involved in construction industry.

Thanks to this awareness, a number of government as well as private agencies or builders have starting opting for green buildings. Thoughthe Public Works Department (PWD) in the city has not as yet announced any green building project, there is a clear inclination towards the concept.

“The department has already started certain projects at certain places in state at places like Nashik and Amravati. In Nagpur, the department has not finalized any projects but surely our upcoming big projects will use the concept of green buildings,” said Nita Thakre, executive engineer (vigilance and quality control) told TOI who was attending a training programme on the subject organized by the civil engineering department at VNIT. Krusha Gharde, an assistant engineer, said thatthe new Ambedkar Bhavan on South Ambazari road was already using rain water harvesting.

Project coordinator of Mahindra Bebanco Developers Ltd who was also attending the training said that the company’s residential project coming up in Mihan was using the green building concept extensively. “We are following the Indian Green Building Council norms. It is expected that everything used in the construction comes from within 500 km radius and is efficiently used. We use fly ash bricks, recycled steel and adopt rainwater harvesting. Above all, MADC has made the provision of a non-domestic water supply system for use of grey treated water,” he said.

Alpana Dongre, architecture and planning professor in VNIT, explained the role of various factors related to the concept. Stressing on the role of use of natural light to maximum possible extent, she said though it aims at getting maximum sunlight but glare has to be avoided. “We also use light sensors for energy conservation. There are also occupancy sensors which put off the light when the place is not used by anyone,” she said. Health of workers during construction and occupants after construction is another prime concept, she said.

Rahul Ralegaonkar, the programme coordinator, R K Ingle, dean faculty students welfare, Prof V A Mhaisalkar, Prof A R Tembhurkar, Prof Rajashri Kotharkar also spoke on the occasion. The training was basically designed for PWD department.

The lowdown on various components of the concept of green buildings

What is a green building?

* Building which efficiently uses energy, water, and other resources.

* Protects occupants’ health and improves employee productivity.

* Reduces waste, pollution and environmental degradation.

* Resource efficient in construction, design, operation, maintenance, renovation, and even demolition.

Components of green building

Sustainable site planning | Preserving and protecting landscape during construction and compensatory forestation | Soil Conservation (post construction) | Reduce hard paving


Use materials like flyash | Reduce volume, weight and time of construction using precast systems and ready mix concrete | Use low energy materials in interiors, minimizing waste, efficient segregation, disposal and recovery

Building energy management

Optimising building design for minimizing use of conventional energy | Energy audit and validation | Using renewable energy sources

Efficient water management

Efficient water use before and after construction | Water recycling and reuse including rainwater

Indoor environmental quality

Provision for minimum health and safety facilities for workers | Reducing air pollution | Using low volatile organic compounds such as paints, adhesives, sealants | Acceptable noise levels | Providing minimum levels of accessibility to disabled.
