Architect designs unique rooftop cooling system, cuts electricity bill by 60%
- •Architect Gokul Goyal from Haryana has developed an innovative roofing method to beat intense summer heat naturally.
- •He replaced traditional concrete layering on his roof using 7000 earthen kulhads and waste tiles.
- •This scientific jugad keeps the top floor cool, maintaining a temperature 5 to 10 degrees lower than usual.
- •The insulation prevents heat from entering through the roof, drastically reducing the need for air conditioning.
- •This passive cooling technique costs around Rs 200 per square foot and has slashed electricity bills by nearly 60 percent.

Haryana-based architect Gokul Goyal renovated his roof by applying a passive cooling technique using 7,000 clay kulhars and waste tiles, which creates an air gap that blocks solar heat and keeps the indoor temperature 5 to 10 degrees lower.
The new roof treatment technique costs around 200 rupees per square foot, which translates to a total expense of roughly 150,000 rupees for a 700-square-foot roof.
Chinese mosaic tiles reflect about 70 percent of heat, while the clay kulhars create an insulating air gap that prevents the remaining heat from penetrating the concrete slab and reaching the rooms below.
