1. Your Concrete Roof Is a Unit of Storage
The majority of houses in Chennai have RCC (concrete) slabs.
During the day:
- The terrace is filled with unending sunshine.
- The trap is made of concrete and not miraculous.
By evening:
- That accumulated heat gradually radiates out into your room.
That is the reason why your room feels the hottest after sunset, not in the afternoon when it is hot.
2. Exposure to the Sun on the Terrace
At such places as Chrompet and Tambaram:
- Detached houses enjoy numerous sunny hours.
- Natural shade is very scanty.
This leads to:
- The surface temperature of the terrace is high.
- Constant heating of the building.
This, in the long run, is the primary cause of indoor heat discomfort.
3. Heat No Barrier: Terrace/Room
The terrace is only fair in most of the houses:
- Plain concrete
- No insulation
- None on a protective roofing
Directly heat flies:
Dining room/terrace → Ceiling wall roofing.

4. It is Worse with Poor Ventilation
In case heat comes in, appropriate airflow can minimize the effects.
But most of the homes have:

- Minimal cross airflow

This causes:

In low-cost and space-limited houses, this is very prevalent.
6. Surroundings Heat Reflection
Your house doesn’t heat up in isolation.
Nearby:
- Concrete walls
- Roads
- Adjacent buildings
All bounce back heat to your building.
Therefore, you can still have your home take on the heat of the environment even in the absence of the sun.
Why is it even more painful in Chennai

- The humidity is high, so that the heat is not able to escape.
- Cooling is delayed at night due to conditions at the coast.
- Exposure is increased by a long summer period.
And when your building gets heat, it is likely to last longer.
