Passive cooling systems are naturally operated. These will make your home naturally Ventilated. This is also one of the sustainable development strategies.
Passive systems based on the climate of the region. Passive cooling techniques implies the hot and dry or hot and humid climates. This will reduce your energy consumption in the home.
Some of the Efficient Passive Cooling Systems Include:
Passive Cooling Through Natural Energy Resources
Natural energy resources are available in unlimited amounts. All we need is to utilize them in proper ways. Some of the natural resources include: Sun, Wind, Water, Soil etc.
Homes are designed to take maximum natural air. Following are some passive strategies:
- Cross ventilation system through practical openings in the home
- Wind catchers to be installed according to the directions of wind
- Orientation of the home in such a way to cut off the sun’s heat in summers.
- Install water bodies within close vicinity of home to make cooling effects.
- Natural vegetation is essential in cooling the environment
Passive Cooling With Analytical Construction Techniques
This will include use of building materials along with construction strategies. Following are some examples.
Passive Shading Devices
Shading is a must to cut off the sun’s radiation from home. Shading devices could be both natural and artificial.
Natural shading includes the landscape around your home while artificial shading would come under construction strategies. This is about providing projections, louvers or curtains.
Most of the windows need projections over them. Louvers would add extra technical shade to the heat while also helpful in winters when heat is required. Moreover curtains help add cooling and insulation to the rooms.
Building Materials and construction techniques
Building materials are available in different types. All you need to do is to use natural materials or reduce the use of artificial materials. Some of the natural materials and construction techniques include:
Brick masonry in place of cement plastered walls would add aesthetic as well as cooling impacts.
You must choose insulating flooring materials to the floors of home as well as to the roofs. Marble is essential for this purpose.
Wall cladding is another option which will be useful to cut off heat absorption. It is a type of plastering to the walls. Providing outside walls would add insulation to heat and a pretty look to the walls.
Passive Cooling By Reducing Internal Heat Gains
Heat is not only concerned with the solar radiations. There are many human induced activities which make your home warmer.
The un necessary usagje of electrical equipments, artificial lights, electrical home appliances and above all restraining natural ventillation from home.
For reducing these things you need to utilize all the openings of your home and let fresh air to enter the home. Keeping your home clean and fresh everytime. Otherwise this would not be cool enough.
Passive Cooling Through Home Architecture
Architecture is a great field which enables the best cooling home strategies through planning and designing. There are places created to make cooling effects in home. Some of them are:
Open Courtyard in home
Courtyard is best suited in homes for natural air inflow. Openess will create ventilation throughout the home. Furthermore Courtyards may be designed aesthetically with green spaces for extra fresh and cooling impacts.
Provision of Ducts and Set back around the home
Ducts are essential for passive ventilation. These would ease air flow and cools the home technically.
Set back is must for homes and there are some standards and by laws for the provision of set back in homes. Providing set back would create enough spaces for windows to circulate airflow.
Architects follows certain contemporary techniques in home planning for the purpose of ventillation.
In this process orientation plays a crucial role while distribution of spaces and development of open spaces would add a lot more.
Architects are capable of creating open spaces in a limited piece of plot. Grid designs, vernacular architecture, insulating building techniques and the overall house design would be made up with passive cooling system.
