Kempegowda International Airport (BIAL)

Introduction

Bangalore International Airport Ltd., Bengaluru (BIAL) is one of the world's busiest and fastest-growing airports with 33 million annual footfalls. Bengaluru Airport's new terminal, "Terminal in the Garden," resembles a garden walk. It is the largest LEED Platinum-pre-certified airport structure. The airport was built on 4 pillars: technology leadership, a terminal built in a garden, environmental and ecological stewardship, and honoring Karnataka’s rich heritage and culture.

BLR Airport has made great strides toward the ‘Green building’ concept by using eco-friendly, biodegradable products in design, construction, and facilitation. Sustainable development targets are met by BLR Airport's environmental strategy, which employs state-of-the-art technology, new services, and innovative ideas. Having switched almost entirely to renewable energy sources, the campus went from water-depleted to water-positive and energy-neutral! The airport also prioritized environmental, waste, and ecological management to promote sustainable growth.

Water Positive & Energy Neutrality

BLR Airport uses cutting-edge technology to conserve water. A weather-based Smart Automatic Irrigation System manages our 100-acre landscape, and terminal washrooms have low-water fixtures. A smartphone app controls this first-of-its-kind weather-based Smart Automatic Irrigation System. It calculates evapotranspiration, soil moisture, and weather to irrigate plants.

With a Hydro-pneumatic Pump Station and Automatic Filtration Unit, the irrigation system saves 30% more water than conventional methods. This smart irrigation system reduces evaporation by applying the right amount of water to plants. Reusing, recycling, and replenishing water is the goal!

Environmental and Ecological Balance

Several steps were taken to reduce the environmental impact of our energy consumption, especially given the role of greenhouse gas emissions in accelerating global warming. 90% of the roof is covered with Solar. BLR Airport has become net energy neutral by using less non-renewable energy. High-efficiency chiller plant is used for the reduction of cooling energy consumption.

As a result, BLR Airport has saved enough energy to power 9,000 homes for a month by conserving energy. Both runways and surrounding streetlights are lit by LEDs, saving energy without sacrificing lighting quality or visibility.
