It is important to consider the orientation before you buy any property (including an apartment or bungalow), or start designing a new house or renovate the house. It is the positioning of a building in relation to seasonal variations in the sun’s path as well as prevailing wind patterns which is most important. The good orientation can increase the energy efficiency of your home, making it more comfortable to live in & of course cheaper to run! For more detailed on orientation, please refer our detailed article: Importance of Building Orientation in Architecture!

Plant Shade

Growing plants and trees outside your house is the simplest way to drive away heat. A deciduous tree provides shade in summer and allows light through their branches which are bare in the winter. Providing an efficient plant shade for the south and west windows will reduce the heat from the sun.

Wet clothes increase the level of humidity in the house.

Cross ventilation allows the static hot air to get replenished and allows fresh air circulating throughout the building.

12. False Ceiling

False Ceiling

False ceiling has become much popular in the recent times. It serves two good purposes. The false ceiling not only gives modern look to the house but is also used for thermal insulation. False ceilings are suspended a few inches below the ceiling on a metal framework which is made from lightweight materials like wood, plaster of Paris, plywood, and gypsum. The air filled in the gap between the two layers of ceilings cools the room. There is a gap between these two layers, hence the air within gets trapped. Air, being a poor conductor of heat, does not allow the heat to flow into the room. Thus, it also helps to reduce electricity bills. Further, if the material of the false ceiling is thermal insulating type, it will further reduce heat and hence inside temperature.

14. Use of Heat Reflective Paint

Heat Reflective Paint on Roof

Heat reflective paint is used as a heat insulating coating on the terrace and rooftop of buildings. Its application reduces the temperature of the roof or slab thereby correspondingly reducing the room temperature. They are called High Albedo Paint but they are very costly. According to Akbari et al. in USA, the use of reflective roof coatings reduced the need for space cooling by about 20% to 70%.

18. Vent and Insulate Your Attic 

Vent and Insulate your Attic

Attics tend to trap the heat, which can make your entire house feel warmer. This is because roofing materials absorb heat. Attach gable-mounted fans to your existing attic vents or install a roof-mounted fan to draw some of the heat out of your attic. Attic insulation, such as foam, fiberglass, or cellulose, also helps to create a barrier that prevents heat from escaping into the rest of your house.
