Inspiring innovation in the built environment.

A unique opportunity for leaders in the building ecosystem to drive the next frontier in buildings

What is the BIGathon?

The BIGathon is a unique opportunity for thought leaders from India and the United States of America to network, engage, and partner in the smart built infrastructure space.


Collaboration between the U.S. and India, the world's two largest democracies, has led to innovations in several spheres. In a novel realization of these bilateral ties, researchers at Lawrence Berkeley National Laboratory have created the Building Innovation Guide (BIG), a premier guide to achieve green, smart, energy-efficient, high-performance buildings in India.


The BIG was launched in five cities in India, Hyderabad, Mumbai, Delhi, Trivandrum, and Bengaluru, through a unique series of events: the BIGathon.


By covering the width and breadth of communities in India,  each with its own challenges and opportunities, the BIGathon seeks to inspire and drive innovation into each city’s own ecosystem.
