MISSION

By forming this club, the student members of our college will get involved in various discussions and activities that promote the use of renewable resources in the process promising sustainability for our future endeavors. 
Being students of architecture, we can incorporate the ideas and facts we gain through our activities and discussions in our design works, making them more eco-friendly.
Since the imperative fields such as sustainability and renewable energy are not very well concentrated on our academics, having such a club will ignite our thoughts and shape us to perform more reasonable deeds in our daily life.Thus, as ‘students for sustainable energy for all’, we amend to turn into a more sustainable livelihood, within a decade from here. And frugality/minimalism will be our ultimate theme.
