My home is opposite

>> Why is my room dark?

How can you compensate for the effect of the opposite side on daylight?

Facing each other in flats is a common situation. In city centres, due to the population density, buildings are built close to each other, separated only by the width of the street or the backyard. With 9,000 inhabitants per square kilometre in Lyon and 20,000 inhabitants per square kilometre in Paris, facing each other in flats is very common in large cities.

Impact of the opposite side on daylighting?

Opposite buildings are an obstacle to natural light. Sunlight can be blocked by the building opposite. The closer the building is opposite, the greater the reduction in sunlight.

 

Light from the sky feeds into the windows, even in an opposite flat situation. However, the canyon effect of the buildings facing each other reduces the available light in front of the windows. This phenomenon explains the loss of ambient light in facing flats.

 

Compensating for the effects on natural light from the flat

Skylight and sunlight are attenuated or obscured by the presence of neighbouring buildings. This is particularly the case for a flat face-to-face. Hence the idea of capturing the least amount of light and sunlight present in front of the windows. This is what the Daylight Reflector allows. Developed by Espaciel, this innovative device allows 50% more light to enter through the windows. This is the trick that occupants of opposite homes can easily implement, because no work is required.
