About Us
As our planet faces the alarming reality of warming temperatures, India is confronting a critical challenge: by 2030, heat stress events could cost the nation 34 million full-time jobs—equivalent to 5.8% of its working hours. In this context, HVAC systems are no longer a luxury but a fundamental necessity.

The escalating demand for cooling in India is projected to necessitate an additional 800 GW of power generation, exacerbating carbon emissions and accelerating climate change. With HVAC systems already accounting for up to 60% of energy costs, the people, the planet, and profit appear to be at cross-roads with each other, making it imperative to decouple the gridlock.

The answer to this impending conundrum lies in Energy Efficiency.
We are Smart Joules. And, we are pioneering the journey towards profitable decarbonization.
Why Us?
OUR VISION
To reduce 29 million tonnes of Co2 by 2030 by pioneering profitable decarbonization.

OUR MISSION
To make energy efficiency simple, substantial and profitable through cooling-as-a-service business models, intelligent automation technologies and efficiency-first processes, culture and values.
