Skylights

Skylights are architectural features designed to introduce natural light into interior spaces through a transparent or translucent window installed in the roof or ceiling. They serve both functional and aesthetic purposes, enhancing interior illumination while often contributing to the visual appeal of a building. Skylights are commonly used in residential, commercial, and industrial structures to reduce reliance on artificial lighting during daylight hours and improve energy efficiency.

The primary types of skylights include fixed, ventilated, and tubular models. Fixed skylights are non-operable and primarily provide daylight. Ventilated skylights can be opened to allow airflow, aiding in natural ventilation and temperature regulation. Tubular skylights, also known as sun tunnels, consist of reflective tubing that channels sunlight from the roof to interior spaces, suitable for small or hard-to-reach areas.

Materials used for skylights typically include glass or polycarbonate, both of which offer varying degrees of insulation, durability, and clarity. Modern skylights often incorporate UV coatings and insulating layers to improve energy efficiency and control glare. The installation of skylights involves careful design considerations, including waterproofing, insulation, and orientation to maximize sunlight intake and reduce heat gain or loss.

Skylights can influence building performance in several ways. They can improve natural lighting and perceived space, promote energy savings, and contribute to indoor environmental quality. However, improper design or installation can lead to issues such as leaks, heat gain, or heat loss. Therefore, selecting appropriate types and materials, and ensuring proper sealing and shading, are essential for optimal function.

Overall, skylights are versatile architectural elements that offer benefits of natural light and ventilation while requiring thoughtful planning to mitigate potential drawbacks.
