Daylit

Daylit refers to a condition or design that allows natural sunlight to illuminate an interior space. This can be achieved through various architectural features such as windows, skylights, light shelves, and atria. The primary goal of daylit design is to reduce reliance on artificial lighting, thereby saving energy and potentially lowering electricity costs. Beyond energy efficiency, natural daylight is also recognized for its positive impact on human health and well-being. Exposure to daylight can regulate circadian rhythms, improve mood, and enhance productivity.

The implementation of daylit strategies involves careful consideration of building orientation, window placement and size, and the use of reflective surfaces to maximize the distribution of natural light. Advanced techniques may include light tubes or solar tubes that channel sunlight from the roof into deeper interior spaces. The effectiveness of daylit design is often measured by metrics such as daylight autonomy, which indicates the percentage of occupied hours when a space can be adequately lit by daylight alone. While beneficial, daylit spaces also require management of glare and heat gain, which can be mitigated through shading devices, high-performance glazing, and careful interior design.
