Solinnslippet

Solinnslippet is a term used in architectural discourse to describe the deliberate management of sunlight entering a building. It refers to the combination of openings, devices, and design strategies that admit daylight while controlling glare, heat gain, and energy use. In practice, solinnslippet encompasses both the placement of windows and skylights and the use of shading, surface reflectance, and interior layout to distribute natural light evenly across interior spaces.

Etymology and usage: The word is Norwegian, formed from sol meaning sun and innslipp meaning ingress or entry, with the definite article solinnslippet in common use. It appears in discussions of daylighting and passive solar design in northern climates.

Design considerations: Effective solinnslippet balances daylight quality with thermal performance. Techniques include clerestory windows, skylights, light shelves, and light tubes, complemented by high-performance glazing, selective glazing coatings, and adjustable shading. Orientation, ceiling height, and interior geometry influence daylight penetration and distribution.

Applications and significance: The concept informs energy modelling, architectural guidelines, and green building standards by highlighting how sunlight can reduce artificial lighting needs while avoiding overheating. It is particularly discussed in contexts seeking energy efficiency and visual comfort without relying on artificial lighting.
