Roof of Hope grows to 1,000 homes
With support from the Nagarro Foundation, our cool roof pilot in Bakkarwala, West Delhi scales up from 100 homes to 1,000 this summer.
Decarbonize. Democratize. Digitize.
Clean energy for India and beyond.
We design, test and scale real-world solutions for the energy transition, bringing technology, policy, economics and human behaviour together in one research platform.

Four areas, one energy system
From the heat on a single roof to the intelligence of a whole grid, our research covers how India will keep cool, stay powered and cut emissions.
Urban microclimate
Measuring urban heat, mapping cities with AI, and turning proven fixes like cool roofs into state policy.

Decarbonizing residential cooling
District cooling and thermal storage that let homes cool at night using solar energy captured during the day.
2 projects
Smart buildings
How technology, occupant behaviour, energy use and indoor air interact, from DC ceilings to air quality in Delhi homes.
5 projects
Smart microgrids
A campus-wide microgrid living lab that brings solar, storage and controllable loads under intelligent control.
2 projectsIndia's largest academic testbed for thermal energy storage
Our Thermal Energy Storage Living Lab stores cooling during the day, when solar power is plentiful, and uses it to cool a 220-room hostel at night. Startups, manufacturers and solution providers can test their technologies here in a real field environment.

Roof of Hope: cooler homes for families who need it most
In a low-income colony in West Delhi, a simple reflective roof sheet made homes measurably cooler in the peak of summer.
68 °CRoof surface before

- 80% of families reported better comfort and sleep
- 95%+ were satisfied overall
- 1,000 homes this summer, up from 100
