Simple home tricks and natural ventilation can greatly save on the use of air conditioning and decrease the indoor temperature by a great deal. Such techniques are effective, as well as energy-saving and environmentally friendly, in hot and humid areas such as West Bengal.
1. Smart Natural Ventilation
The most comfortable method to cool your house is to enhance the circulation of air.
Keep windows and doors open in those early mornings and evenings when there is cooler air outside.
Open cross-ventilation by opening opposite side windows.
Add a fan that will blow out hot air and an inlet fan that will introduce fresh air.
Install exhaust fans in kitchens and bathrooms to get rid of trapped heat.
This constant flow of air assists in forcing out hot air, and the cooler air is externally drawn in.
2. heat out before it gets in
It is better to prevent than to cool.
Close curtains, blinds or shutters at the time when heat is at its peak (10 AM 4 PM)
Apply blackout/light coloured curtains to reflect sunlight.
Put reflective window coverings to cut down heating indoors.
Plant shade trees or climbing plants along the windows to avoid direct sunlight.
Even minor changes in shading would have a significant effect on cooling off the temperature indoors.
3. Evaporative Cooling Tricks
Simple yet effective cooling methods are water-based.
- Keep a bowl of ice or frozen bottles of water in front of a fan to achieve instant coolness of air.
- Hang wet cotton curtains or sheets in open windowed homes in order to cool the incoming air.
- Apply a wet cloth to the windows at night in order to cool down incoming breath.
- Replace bedsheets with cotton and do not use items that tend to trap heat, such as synthetic fabrics.
These are particularly effective where the humidity is dry-to-moderate.
4. Khus (Vetiver) Chilled down- Desi-style
Among the best natural ways of cooling is through the use of khus (vetiver) curtains or mats.
- Khus cools the air passing through it when it is kept a little wet.
- It is a conventional evaporative cooler.
- Also introduces a new, rustic scent to your house.
- Good on doors, balconies and small windows.
- The cooling effect lasts longer by pouring water 2-3 times daily.
