can be enough
An awning is the oldest air-conditioning system and is still effective. An outdoor awning – such as a drop or arm awning – can lower the internal temperature by a few degrees during the hottest hours of the day.
This is more effective if the fabric of the blind is dark, as it is more resistant to solar energy than a light fabric.
The air conditioner can be switched on for less time, or not at all, which saves on energy bills. The European Parliament recognises solar shading as one of the ways to reduce energy costs in buildings.
