FAQS about Pipeline daylight and solar power
What is a solar pipe?
Solar pipe or sunpipe, as it is normally called and trademarked by Solatube, has several other names trademarked by various manufacturers which include light pipes, solar tunnels, sun tubes, light tubes, sunlight tubes, daylight pipes, and light tunnels.
Can a heliostat be used in a light pipe daylighting system?
In a light pipe daylighting system, it is possible to add a heliostat that reflects incident light and dramatically improves the performance of light pipes at low altitudes. For optical fiber-based daylighting systems, the attenuation limits the transmission efficiency of optical fiber, as shown in Figure 10.
How effective are daylighting systems?
In addition, the effectiveness of daylighting systems depends on the design or performance of commonly used optical materials, such as glass, lenses, polymers, and plastics. Thus, the efficiency of the light pipe is strongly influenced by the optical geometry and reflection time of the light pipe itself.
Does daylight save energy?
Daylighting can save energy for lighting up to about 63% for user input setup and 68% for automated setup . Until the 1940s, daylight was the main source of light for buildings, and it was supplemented by artificial lighting .
