NKDA announces incentives for green buildings in Kolkata

The New Town Kolkata Development Authority (NKDA) is encouraging builders to build more green buildings in Rajarhat, New Town.

The authorities recently gave green signal to the decision of 2% reduction in the building plan sanction fee for developers who would be able to present a provision where recycling of grey water can be done using the dual-pipe system so that the water could be used for gardening or washing cars.

A further 2% incentive would also be given if the solid waste generated for the building is recycled through composting.

A meeting was held recently among senior NKDA officials to discuss ways to implement these incentives so that real estate developers cooperatives or individual building owners are encouraged to design and come up with green building modules to develop New Town into a smart green city .

Officials mentioned that the current rules will be amended by the state government once the recommendations are passed. According to NKDA rules, a 2% incentive is already provided for having provisions of rainwater harvesting and solar energy .

Earlier this year, the Housing Infrastructure Development Corporation (Hidco) allowed a 10% additional floor area ratio (FAR) over the usual FAR for constructing residential buildings in New Town by following the green norms. Residents were encouraged to set-up more multi-storied parking spaces.

Residents are being encouraged to set up more multi storied parking spaces in big commercial and residential complexes like malls and hospitals, the extra parking space will not be counted as consumption of FAR, added officials.

In another effort to turn New Town into a solar city, NKDA made it mandatory for all commercial and residential multi-storied high rises in the township to install solar rooftop panels that could meet 2% of the total electrical load.

The green building technical committee of the state urban development department follows a number of recommendations, among them are use of two glass panes with a layer of 6 mm air in between to ensure good insulation, use of auto-claved aerated concrete bricks that will help keep the interior cool, dual plumbing system for water re-use, more open space than the minimum allowed under building laws and use of LED fixtures.
