The HUDA administrator, Mr Praveen Kumar, said that Gurgaon can be better planned city. Issues like green buildings, water conservation, solar powered harnessing, etc. should proactively address to make the city more sustainable. Gurgaon already has a number of green buildings to its credit such as ITC Green Centre, Fortis Hospital, IRRAD building, Wipro Campus, Delta India Electronics Unit, TAtvam Vilas and the TERI Retreat.
