What is Daylight Harvesting?

Daylight Harvesting exploits on the simple preface that can optimally utilize natural lighting and cut down the usage of artificial light during daylight hours.

Daylight harvesting can also be defined by terms like skypipe, light pipe, skylight, solar light, and natural lighting designed ideally suited for the environment considering the extreme weather conditions and industrial dust.

Nowadays commercial buildings are often designed with glass exteriors, which makes it ideal for letting in some skylight. Daylight solar light will provide pure natural dynamic daylight for 11 - 12hrs in a day to the interiors. According to the Commercial Buildings Energy Consumption Survey (CBECS), artificial lights are responsible for nearly 17% of the energy consumed in a commercial building and can be even higher depending on usage.

How important is Daylight Harvesting:

  • Lowers lighting energy cost.
  • Reduced carbon print and sustainability
  • Employee Health and Wellness help to reduce eyestrain by drowsiness 55% and whopping 50%, and headaches by 62%.
  • Virtually maintenance free for life.
  • Eliminates the risk of rooftop accidents which occurs due to transparent sheets.
  • Highly light capture at low sun angles (i.e before 9 am and after 3 pm).
  • Works effectively during low light levels like cloud and rain.
  • Provides natural dynamic daylight for 11 - 12hrs in a day to the interiors.
  • Lower cooling energy.
  • Uniform light dispersion.
  • A unique diffuser diffuses light uniformly.
  • Daylight can reach false ceiling covered areas.
  • The Light level and diffusion can be planned as per artificial lighting.
  • Impact-resistant Light collector.
  • Low rooftop aperture requirement (1–1.5%).

  • Why to use it ?

    In most global buildings, lighting energy usage is around 44% of all consumed electrical energy. This daylight can cut down this percentage can have a positive impact on your electricity costs. In fact, depending on the depth of daylight harvesting system, we can save our lighting energy bill anywhere from 10% to 46%. Also, because daylight harvesting has a lower cooling load than electric lighting, we can also see a reduction in your air conditioning costs.
