Light
Sunlight where and when we need it.
A correctly designed apartment in terms of access to natural light is one that provides sufficient daylight in the most important zones of daily life. It's about interiors being bright, pleasant and supporting the residents' natural circadian rhythm. In practice, this means good orientation relative to compass points, appropriate size and placement of windows, and a room layout that allows light to reach where you spend the most time. It's also important that the apartment is not excessively shaded by other buildings, balconies or overly deep interiors.
What exactly do we analyse?
Sunlight potential
what proportion of the room has the potential for sunlight access in morning and afternoon hours
Access to natural light
we analyse the window area and its ratio to the room size, checking whether the room depth allows light to reach the entire floor area
Impact on our well-being
Natural light is one of the strongest regulators of human well-being in a living environment. It directly affects the circadian rhythm, regulating sleep, wakefulness, and energy levels throughout the day. A well-lit apartment supports serotonin production, improving mood and concentration. A lack of daylight increases the risk of low mood, apathy, and chronic fatigue. Natural light helps the body synchronize better with the times of day and the seasons of the year. The quality of light in a space affects how we perceive the size, warmth, and sense of safety of the interior. Apartments with access to morning light support gentler waking and a more stable daily rhythm. Layouts that are too deep or lit from only one side can cause discomfort and impair concentration. Daylight strengthens the connection with the surroundings and the sense of being grounded in a place. As a result, good daylight access is a foundation of both the mental and physiological health of residents.
What to watch out for
The apartment gets sun only when you're not there. Rays appear at midday, but the morning and afternoon light we need is absent
Windows are not positioned centrally, resulting in uneven illumination of rooms
