CLIMATE RESILIENT



CHAPTER-XI -3 (G.O.119 Contd..)

CLIMATE RESILIENT CONSTRUCTION:

INTEGRATION OF ENVIRONMENTAL CLEARANCE WITH SANCTION

General:

Land, Air, Noise, Water, Energy, Biological/Socio-Economic/Solid/Other Waste Management are the main facets considered in relation to Pre, During and Post Building Construction for Sustainable Environment Management. The building construction sector is a major contributor towards carbon footprints which affects climate change. It is necessary for the building process to ensure compliance to various conditions laid down by the Ministry of Environment, Forest and Climate Change, Government of India.

Environmental Conditions for Compliance During Building Approvals:

The Ministry of Environment, Forest and Climate Change has decided to integrate the environmental concerns into building plan approval process and empowering the concerned ULB/Development Authority/any other body authorized to sanction building plans, to approve and certify compliance of stipulated requirements.

The new building construction proposals are classified in the following 3 categories:-

Category

Built Up Area (sq. m)

A

5000 –            20000

B

20000 –50000

C

50000 – 150000

The ULB/Development Authority/any other body authorized to sanction building plans shall approve the building plans by ensuring the stipulated conditions in Table 37 (for above 5,000 sq. m and up to 20,000 sq. m), Table 38 (for above 20,000 sq. m and up to 50,000 sq. m) and Table 39 (for above 50,000 sq. m and up to 1,50,000 sq. m).
