In­dia has over three bil­lion sq ft of reg­is­tered green foot­print, the sec­ond largest glob­ally. Of this, a large chunk, how­ever, in­cludes com­mer­cial realty space. With in­creas­ing pol­lu­tion and a large num­ber of hous­ing so­ci­eties man­aged by res­i­dent wel­fare as­so­ci­a­tions, it is nec­es­sary to en­sure that all res­i­dents in such so­ci­eties lead healthy lives in a green en­vi­ron­ment.

Green prac­tices can be eas­ily im­ple­mented in hous­ing so­ci­eties through sim­ple, cost-ef­fec­tive steps such as a no-smok­ing pol­icy in com­mon ar­eas, im­part­ing green ed­u­ca­tion to occu- pants, lay­ing walk­ing tracks, fol­low­ing rain­wa­ter har­vest­ing prac­tices, land­scap­ing ar­eas, in­clud­ing wa­ter ef­fi­cient fix­tures, seg­re­gat­ing dry and wet waste, us­ing so­lar power for com­mon area light­ing and en­cour­ag­ing in­stal­la­tion of elec­tric charg­ing points for ve­hi­cles in com­mon ar­eas.

Aim­ing to en­cour­age more res­i­den­tial so­ci­eties to go in for a green rat­ing, the In­dian Green Build­ing Coun­cil (IGBC) launched a Green Res­i­den­tial So­ci­eties Rat­ing Sys­tem (per­haps the first of its kind in the coun­try) for ex­ist­ing multi-dwelling com­mu­ni­ties (pi­lot version) at the Green Build­ing Congress 2015 held in Gand­hi­na­gar, Gu­jarat, last week.

Around 10 builder so­ci­eties, mostly in Pune and Mum­bai have signed up for the ini­tia­tive since the launch of the sys­tem, which trans­lates to 5,000 flats spread across 4.0 mil­lion sq ft area. “By the end of next year, as per con­ser­va­tive es­ti­mates, we an­tic­i­pate rat­ing 60 to 75 so­ci­eties/projects,” say IGBC sources.

For a rat­ing, any res­i­den­tial so­ci­ety (builder, co­op­er­a­tives, decades-old DDA so­ci­eties) op­er­a­tional for over and above a year can reg­is­ter. This in­cludes both DDA so­ci­eties spread across Delhi, co­op­er­a­tive so­ci­eties across NCR and projects de­vel­oped by pri­vate de­vel­op­ers which meet spe­cific cri­te­ria.

There are var­i­ous lev­els of rat­ing and for very ba­sic cer­ti­fi­ca­tion, a so­ci­ety has to score 30-39 points on cer­tain pa­ram­e­ters. A sil­ver cer­ti­fi­ca­tion is re­quired for 40-49 points; for gold 50-64 points are needed and for a plat­inum rat­ing, so­ci­eties need to score 65 and above. (See box)

Reg­is­tra­tion costs come to ` 10,000 and the cer­tifi­cate fee is ` 85,000 for up to 100 units, ` 1,30,000 for over 101 to 500 units, ` 1,75,000 for 501 to 1,000 units and ` 2,20,000 for over 1000 res­i­den­tial units, say IGBC sources.

The cer­ti­fi­ca­tion is valid for three years from the date of the cer­ti­fi­ca­tion. So­ci­eties can also up­grade their rat­ing by ap­peal­ing to the IGBC for a nom­i­nal fee in th­ese three years. There­after, they can re­new their rat­ing, say IGBC sources.

The rat­ing will help res­i­dents get a rea­son­able ap­pre­ci­a­tion of 5% to 10% in property rates, says V Suresh, chair­man, pol­icy and ad­vo­cacy com­mit­tee, IGBC. In the long run, he said such rat­ings will help res­i­dents avail property tax in­cen­tives.
