- Double walls with air gap save more energy
- Add heat-resistant paint on outside walls
Best Wall Materials
- Fly ash bricks: Cheaper than clay bricks, keep rooms cooler
- AAC blocks: Light weight, good insulation

Wall Colors
- Light colors for outside walls (white, cream, light yellow)

- Plants cool the air and give fresh herbs
Window Planning (खिड़की का प्लान)
Window Size and Position

- Water features like small fountain add cooling
Room Height
- Make ceilings 12 feet high instead of 10 feet
- High ceilings keep hot air up, cool air down
- Add ceiling fans for better air movement
Insulation Methods (गर्मी से बचाव)
Roof Insulation
- Put 6-inch thick insulation under roof
- Use thermocol sheets – cheap and effective
- Reflective foil on top bounces heat away
Wall Insulation
