It’s hot in your house ? We give you tips to refresh your interior without paying a penny (or almost).
1. Use green plants
To create more freshness in your home, you can use green plants such as leafy or deciduous plants. They will release water and heat. They can be placed on window sills to freshen the air.
2. Reduce or eliminate the use of lights and appliances
They emit a lot of heat, especially ovens, clothes dryers and halogen lamps.

3. Drafts can be created between different rooms in your home.
Drafts can be created between different rooms in your home.
4. Night ventilation
Ventilate the night if the outdoor temperature is lower than the indoor temperature. This will allow you to lower the temperature by 1 to 4.5 degrees Celsius.
5. Close blinds and shutters
Block the heat of the sun from entering your home. Close the shutters (exterior blinds work better than interior blinds). This will allow you to lower the temperature by 1 to 3.5 degrees Celsius. Roller shutters are particularly effective. You may also consider using plants (bamboo or other) to block the sun’s rays. Place them outside your windows.
6. Close the doors
Between rooms of different temperatures, because the heat always goes towards the cold.
7. Water evaporation
Use evaporation water: each gram of steaming water removes 600 calories from the air and cools your home. To take advantage of this, you have three options:
- To cool a room, lay a sheet or towel in front of an open window.
- Dry your laundry indoors.
- To get a thin layer of water on your indoor floor, run a damp mop over it.
8. Lower your body temperature
Lower your temperature bodily by drinking water and wearing loose clothing.
9. Use a UV filter on your windows
Use anti-UV films onyour windows. They are transparent and removable and can reject up to 88% of solar energy, thus lowering the ambient temperature. They cost between 12 and 30 euros per m2.
10. A fan can be very useful
A fan is a useful tool if the temperature in your home is too high. It consumes little energy and can be placed in front of a damp cloth to reduce the heat in your home. It should be turned off when you’re not around.
