If you’ve ever stood under a tin roof in May, you already know the problem we’re describing. Now imagine that roof isn’t over a warehouse or a workshop, it’s over a one-room home in a slum settlement, where a family sleeps, cooks, and lives all day, every day, through a Gujarat summer that can stretch five to six months.
That’s the problem the Healthify Slums campaign was built to solve. It’s an initiative run by the GCGC Foundation, a registered NGO based in Vadodara that works on practical, low-cost green-technology projects across Vadodara and, through its Bloom Foundation partnership, in Pune as well. Panache Green supports the initiative because it sits squarely inside what we care about: reducing heat where people actually live, not just where it’s profitable to sell paint.
A bare metal roof in direct summer sun can reach surface temperatures near 75–80°C. Almost none of that heat has anywhere to go in a small, low-ventilated room, so it just builds up indoors, reports on Indian slum housing during heatwaves have put indoor temperatures as high as 50°C. Over 70% of slum households in India have no electricity or only limited access, so running a fan through the night usually isn’t an option. The result isn’t just discomfort; health workers and researchers have documented real consequences, heat rash, dehydration, disrupted sleep, and worse for young children and the elderly, who are least able to cope with sustained heat stress.
The fix Healthify Slums pilots is a solar-reflective, IR-reflective, coating applied directly to the metal roof, which reflects away the infrared component of sunlight before it turns into stored heat. In the pilot rollout in the Channi area of Vadodara, the coating brought roof surface temperatures down by roughly 20–30°C compared to an untreated sheet, a meaningfully cooler home without adding a single appliance or a single rupee to anyone’s electricity bill.
The beneficiaries are low-income families across tropical and sub-tropical regions where summer temperatures climb dangerously high and households simply don’t have the resources to protect themselves from a superheated roof. Around 95% of slum housing uses low-clearance metal roofing, the cheapest durable option for all seasons, which routinely hits 80°C on the surface and turns the home underneath into a furnace. In cities like Vadodara, that isn’t a two-week heatwave, it’s a five- to six-month reality every year. With over 70% of slum households lacking reliable electricity for a fan or exhaust, treating the roof itself is often the only realistic intervention.
It’s a small example of a bigger idea Panache Green keeps coming back to: cooling a building doesn’t have to mean cooling it with more energy. Sometimes it just means reflecting the sun’s heat before it ever gets in.
