A comprehensive waste management policy was incorporated along with rain water harvesting and 100% use of recycled water. About 17 lakh square feet of green landscape on air side has been featured. Water-efficient landscaping is achieved through no Potable Water use and treating and reusing the sewage. Water Efficiency in Air conditioning System was achieved through the Sewage Treatment Plant (STP).
Special attention was paid to indoor environmental quality with a primary focus on daylight.
