This time the weather is too hot as compared to previous years. So we have to care how to prevent the heat.We can keep our windows open in the morning and afternoon. We can keep wet cloth in the window and it will reduce the temperature of the wind to room. If we keep small plants inside the room also will reduce the heat. While building new house itself plant trees around the house. We have plant good trees to get more cooling. The big size windows we can keep it in the north and south directions. The maximum fresh air should come inside the room with this. The sunlight will reach in the east and west directions and there will be less hot. Here there should not be wall and can keep car porch or sit out. While designing a house or at the time of maintenance we have to change it as open area. Make sure about the cross ventilation. Thereby we can reduce the heat.
