Daylighting and lighting : Under a Nordic sky
(2025) 1.- Abstract
- After nearly a century in which electric lighting has dominated interior building design, there is now a shift back to using daylight as the primary ambient light source. This return is driven by considerations of energy efficiency, environmental impact, and human health. Effective daylighting in building interiors not only supports low energy consumption, but also has the potential to reconnect people to the natural day-night cycle, which is known to enhance health and well-being.
Daylight is particularly significant for people in the Nordic countries, where light is scarce in the winter and overabundant near the summer solstice. The unique character of Nordic daylight—characterized by weak intensity in winter and low sun angles...

This return is driven by considerations of energy efficiency, environmental impact, and human health. Effective daylighting in building interiors not only supports low energy consumption, but also has the potential to reconnect people to the natural day-night cycle, which is known to enhance health and well-being.
Daylight is particularly significant for people in the Nordic countries, where light is scarce in the winter and overabundant near the summer solstice. The unique character of Nordic daylight—characterized by weak intensity in winter and low sun angles in summer—demands careful study and consideration, as it holds special value in this region.
However, the trend of urban densification makes it increasingly challenging to ensure adequate daylight in buildings under Nordic sky conditions, particularly in winter. Advanced building simulation tools are often necessary to accurately predict daylight levels and guide design adjustments. Building regulations and certification standards, which play a critical role in promoting sustainable daylighting practices, must be thoroughly understood by practitioners. Additionally, integrating state-of-the-art electric lighting technologies, such as LEDs and advanced control systems, with daylighting design is essential for optimal results.
Addressing these challenges, this book offers essential knowledge and background for students and practicing professionals seeking to illuminate buildings under a Nordic sky. It focuses on utilizing daylight as the primary ambient light source, with support from energy-efficient electric lighting systems.
