Effect of atrium geometry and reflectance on daylighting in adjacent rooms

Atria are implemented in buildings to increase daylight, foster interaction and provide ventilation. However, their implementation can be complex if good daylight is to be achieved. This research proposed an investigation about the atrium parameters that affect daylight conditions in a case study. T...

Description
Summary:Atria are implemented in buildings to increase daylight, foster interaction and provide ventilation. However, their implementation can be complex if good daylight is to be achieved. This research proposed an investigation about the atrium parameters that affect daylight conditions in a case study. This evaluation concentrated in the atrium geometry and the wall reflectance values. Overall, the outcomes demonstrated that shifting the atrium from an enclosed to a semi-enclosed one can double the daylight in the atrium adjacent rooms. Moreover, it is possible to achieve better daylight in the adjacent rooms by keeping the same floor area of the building.
