Cross ventilation
Passive Cooling
Cross ventilation techniques helps us to cool down our homes, we won’t be as reliant on a air conditioner. In turn, this means less expensive energy bills. It is one of the most effective natural ventilation method for our house. It allows fresh air to enter the room and hot air to leave, thus creating a circle of air flow. If Cross ventilation is considered during planning stage, the result may be a cooler house at less expensive energy bills.
Passive cooling is the least expensive means of cooling our home. It means using design choices to reduce heat gain and increase heat loss. Passive cooling is especially useful in hot and humid or hot and dry climates. It can significantly increase our comfort and reduce your energy bills.
There are many ways we can design or modify our home to achieve comfort through passive cooling. So it is best to use these design principles when planning and building a home.

Passive Cooling Techniques
Wall Insulation:
Wall insulation is a method to reduce the transfer of heat from outside to inside of our homes. It makes our homes insulated. An insulated home is more comfortable as the temperature remains consistent over weather changes. It makes our home comfortable and keeps the temperature of home cool in summers and warm in winters. It is very useful to keep the temperature of the house independent from outside temperature.
Thus, if we provide wall insulation during planning and building stage, we save by lowering energy bills.
Renewable Energy
Choosing renewable energy sources for our home electricity and cooling is a great way to reduce our carbon footprint, make our home more sustainable, and potentially lower our energy costs. The advantages are certainly significant.
Renewable energy is generated from natural sources, such as the sun, wind, biomass and water. And these renewable energy sources are naturally replenished.
Roof Insulation & Thermal Emittance
Insulated & thermal emittance roof is designed to reflect more sunlight than a conventional roof, absorbing less solar energy. This lowers the temperature of the building just as wearing light-colored clothing keeps you cool on a sunny day. It Reduces energy bills by decreasing air conditioning needs, improving indoor comfort and safety for spaces that are not air conditioned and decreasing roof temperature, which may extend roof service life.
Windows Natural Lighting
Just to escape the scorching heat, we most often deprive ourselves of the precious hours of daylight that are so abundantly available to us during the long summer days. This not only results in a much steeper electricity bill for the more artificial lighting we use instead but also leaves the inside of our homes dull and gloomy, resulting in general lethargy during the day.
We need to design our home to let in more light, but without the accompanying heat.
Sun shading
External sun shading is introduced within the design of the building facade so as to reduce heat transfer from the exteriors into the interiors of the building. This is an efficient way to achieve a comfortable indoor temperature and make the building energy-efficient by reducing the overall air-conditioning costs.
Orientation of house
Orientation is the position of your home in relation to the path of the sun and the prevailing wind in your region. Good orientation can significantly improve your comfort and reduce your heating and cooling needs. The best orientation for your home is the one that suits your climate zone. Orientation for passive cooling aims to eliminate solar access with appropriate shading (especially to the east and west), and maximise access to cooling breezes. Orientation for warming in winter and cooling in summer aims to maximise southern exposure of walls and windows, but block solar access with appropriate eaves and other shading in summer.
Good orientation can be achieved with careful design and is best achieved when we are planning or building a home.
