Some of the proposed energy-saving and sustainable features include:

• Solar Farming
• Bio-digesters for sewage treatment
• Reforestation
• Electric/solar-powered Feeder Vehicles
• Double glazed building envelope with sun-shading elements
• Rain-water Harvesting
• LED Lights
• Efficient Central Air-conditioning
• Pre-cast construction methodologies to save time and cost

Steps have been taken to implement this from the development stage itself. Some of these steps are as follows:

• Bio-digester Technology

Airport South will reportedly be the first Metro station in the country to implement this technology which was conceived by the DRDO to degrade and convert human waste into usable water and gasses in an eco-friendly manner.

• Rainwater-harvesting

The stations will come equipped with rainwater harvesting system to avoid wastage of rainwater and to recharge groundwater.

• Soil conservation

The soil removed during construction is being used for planting native trees, which require less water, on the premises of the metro stations.
