The alternative route was developed for rooms in Healthcare developments with multiple functions within the same space, and as such, having different daylight needs at various points within the room.
For other building types, an assessor wishing to use the alternative route to compliance for daylighting should contact the BREEAM technical team with details and justification.
The alternative route was applied to Healthcare building types specifically because these building types are likely to have spaces that have varying needs for daylight. For example, in a hospital ward, the areas where patient beds are located will benefit from good daylight, whereas this is of less importance for the nurses stations, which are used intermittently.
