Green building of the Environment Ministry showcased to the UN Secretary General
Shri Prakash Javadekar meets UN Secretary General Ban Ki-moon
The Minister for Environment, Forests and Climate Change, Shri Prakash Javadekar today met the UN Secretary General, Mr. Ban Ki-moon at the New Paryavarn Bhavan Building. Shri Javadekar showcased to the Secretary General salient features of the Green Building and highlighted that the design philosophy of the New Paryavaran Bhavan focused on increasing the efficiency of resource usage i.e. energy, water and materials while minimizing the impact of the building on Human Habitat and the Environment.
Shri Javadekar further said that this had been achieved through careful site planning, most appropriate building form and very low effluent disposal and energy production on-site. The objective was to have a ‘Green Building’ with a state of art modern amenities and comfort with Intelligent Building Management System which optimizes the energy consumption.
The basic design concept of the project was to have a NET ZERO ENERGY consuming green building. It was expected to be the flag bearer for ‘Green Buildings’. The building has the highest green building rating of ‘5star’ of GRIHA of Ministry of New & Renewable Energy and also ‘Platinum’ rating of LEED India of Indian Green Building Council.
The architectural design of the building is primarily based on following concepts.
· Preservation of maximum possible number of trees standing over the site
· Solar Passive Architecture with proper orientation and shading of Fenestrations
· Appropriate building envelope design with envelope insulation to reduce heat intake.
· Use of permanent, durable and local materials such as sand stone on exterior face, low heat transmission glass, reflective roofing, etc.
· Priority for pedestrians in the front, with vehicular access on the sides of the building
· Reduction of conventional lighting load by ensuring 75% day-light use
· Natural ventilation due to stack effect
· The building is designed in such a way that there is free ventilation across the entire building.
Energy Conservation Measures
o Many energy conservation measures have been adopted to optimize the overall design load.
o Utilization of High Efficiency Solar Panels to achieve Net Zero criteria. Energy efficient T-5 and LED fixtures
o Innovative chilled beam system for cooling
o Pre-cooling of fresh air from exhaust using heat recovery wheel in order to reduce load on chiller plant
o Water cooled chillers
o Double skin air handling units with variable frequency drives
o Geo thermal heat exchange technology used for heat rejection from Air-conditioning system.
o Innovative energy saving regenerative lifts which have been installed for the first time in government institutional building.
Mr Ban Ki-moon also planted a sapling at the premises jointly with Shri Prakash Javadekar to mark the occasion.
