Access to sunlight is regulated in the BBR. The requirement means that residential apartments must be designed so that any room, or separable part of a room, in the apartment receives direct sunlight during some time of the year. solar radiation is measured in hours that a surface is exposed to direct solar radiation, but no minimum requirement is specified in the legislation.
All bedrooms, kitchens, living rooms and other rooms in which people stay regularly for longer periods must be assessed for all floors of the building. Hygiene rooms, garages, storage rooms and similar spaces are not covered by the requirement for access to direct sunlight. We use the latest digital technology to perform simulations of the sunlight.
