Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA) has been recertified for its Terminal-2 (T2) as a ‘PLATINUM rated Green Existing Building Project’ for the period from 2021 to 2024 by the Indian Green Building Council (IGBC). The recertification comes as the acknowledgment of the continued efforts by CSMIA to sustain the superior operational performance, maintenance, and occupant wellbeing features at the airport for the second consecutive time. After achieving the last title in the period 2016-2019, CSMIA has continued to consistently demonstrate its commitment to prioritising and enhancing its green practices in its day-to-day operations for a sustainable tomorrow.
Over the years, CSMIA has redefined the green processes at the airport by undertaking sustainable operations targeting key features such as water efficiency, energy efficiency, health & wellness practices amongst others. These developments bring in operational efficiency while also using innovative technology to address the challenges under environment management. Among the series of green initiatives undertaken at CSMIA, some of the key features honoured by IGBC are as follows:
- Onsite solar energy generation of 53,10,141 kWh with nearly a solar energy share of 6.6 percent of net energy consumption
- Retrofitting of existing lighting fixtures by LED fixtures for all external lights resulting in a reduction in load contributed to reduced energy utilisation at the airport, resulting in the consumption of approx. 6.5 Million units per annum
- Replacement of belt driven centrifugal fans with EC fans in Air Handling Units (AHUs) improve the overall energy efficiency, reduce energy consumption and significant reduction in maintenance time
- Installation of IoT-based sensor for temperature monitoring with the Wi-Fi enabled temperature sensors at multiple strategic locations across T2 to capture cold and hot pockets. It also allows for real time precise monitoring and control of the entire building temperature and cover the pockets not catered to by the Variable air volume (VAV) systems.
CSMIA offers a holistic approach towards sustainable operations and has carried out various initiatives under environment management. The IGBC Green Existing Building O&M is the first rating programme developed in India where the rating is focused on the sustained performance of buildings. With consistent efforts, CSMIA has been able to save approximately 13 million units of energy per annum by the implementation of energy conservation measures and has reduced around 2 MW load on the grid.
Meanwhile, under the zero-water discharge policy, CSMIA has the STP to treat the water and use treated water for the cooling tower as well as for horticulture purposes. CSMIA has 229 rainwater harvesting pits across the terminals for recharge of ground water table to ensure water efficiency. Whereas with the consistent adoption of latest technology, CSMIA aims to move towards achieving 100 percent energy requirement fulfilled through renewable energy in the coming years. Some of the core focus areas include carbon management system, carbon neutrality, renewable energy installations, wastewater recycling, effective waste management system enhancement in renewable energy capacity which are not just in alignment with the pillars of the IGBC rating criteria but also meet the global standards of sustainable practices proposed by renowned organisations across the world.
