I live in Rajkot, India. Temperature goes above 40 *C (104 *F) for at least 4 months a year.
I live in a single floor house with 3 sides of house and roof is exposed to sunlight.
It's a house built with brick walls, plaster and concrete slabs. flat roof floor is tiled with white ceramic tiles. Outer walls are painted white.
Is there anything I can do to reduce the inside temperature?
