Päivittäisvalaistus

Päivittäisvalaistus is a Finnish term that translates to "daily lighting" or "daylight lighting." It refers to the use and integration of natural daylight into interior spaces for illumination. This concept goes beyond simply having windows, focusing on maximizing the amount and quality of daylight that enters and is distributed within a building.

The principles of päivittäisvalaistus are applied in architectural design to reduce reliance on artificial lighting during the day. This is achieved through various strategies, including the orientation of buildings, the size and placement of windows, the use of light shelves, reflective surfaces, and atriums. The goal is to provide sufficient illumination for activities while also enhancing the aesthetic appeal and well-being of occupants.

Effective päivittäisvalaistus can contribute to energy savings by decreasing the need for electric lights, which in turn lowers electricity consumption and associated costs. Furthermore, exposure to natural daylight has been linked to numerous benefits for human health and productivity. These include improved mood, better sleep patterns, and enhanced visual comfort.

Designing for optimal päivittäisvalaistus requires careful consideration of factors such as geographic location, climate, and the specific function of the space. Techniques like daylight modeling are often employed to predict and optimize daylight performance. Ultimately, päivittäisvalaistus is a key aspect of sustainable and human-centered building design.
