By positioning a house to receive less direct sunlight during the hottest parts of the day and taking advantage of natural shading devices such as trees, overhangs, or awnings, it is possible to reduce the amount of heat that enters the house. Additionally, by positioning a house to take advantage of prevailing winds and create cross-ventilation, hot air can escape and cool air can enter, reducing the need for artificial cooling systems such as air conditioning.


Insulation and Ventilation



Insulation and ventilation keep houses cooler even during the hottest days. Insulation helps by preventing heat from entering the house from the outside and keeping cool air inside the house. This can be achieved by using materials with high thermal resistance such as fiberglass, cellulose, and foam can help keep your houses insulated.


Ventilation, however, allows hot air to escape and cool air to enter. To make a well-ventilated house, including windows, doors, and vents to allow passage of cool air inside and to let out hot air. You can also use fans and aircon to circulate air around the house to keep it cool.

Indoor Plants


The green won’t only keep the house cool from the outside, but also from the inside. Indoor plants reduce the temperature and improve air quality through transpiration and evaporative cooling. Plants release moisture through tiny pores (transpiration) which cools the surrounding air and reduces the temperature indoors. As plants release moisture, the humidity levels increase, making a more comfortable indoor environment.
