Use of Daylight Harvesting : A Natural way of Energy Saving in Lighting....
Modern offices are designed with glass walls / large windo Similarly ,roofs of industrial shop use of Energy saving in lighting .
However , generally we observe that these sources of sunlight are covered with blinds or curtains . Polycarbonate sheets get covered with something to obstruct sunlight.
Why it is done ? Primarily to avoid glare & heat , associated with the sunlight. As the glass windows or polycarbonate sheets can not filter the heat & glare , it creates uncomfortable feeling for the occupants, results into more energy consumption of Air conditioners.
So, it is a regular experience for all of us to see use of artificial lighting (Energy Saving in Lighting) during daytime.
This results into not only wastage of electricity but also few more disadvantages such as :
- More loading on air conditioning systems due to sources .
- The occupants of the space are deprived of the useful vitamins ( only source is Sunlight ) like Vitamin D3, which is a normal weakness among professionals.
So, the solution is to use sunlight by avoiding the glare & heat . There are two such solutions :
How does it work ?
Lightpipe is a pipe made of a high quality reflective material, which absorbs the sunlight from all directions & delivers to the space in a diffused format . Lightpipe can be fitted on false ceiling , side walls . It can It can directly replace a lamp during daytime .
Norikool is designed to be installed on metallic or cement roof sheets , in place of polycarbonate or fibre sheets . There are two layers of specially defined shapes of polycarbonate sheets. The upper layer has a prismatic texture which enables Norikool to attract more sun light from all directions even during evening hours . The lower layer of polycarbonate , which is placed 4 inches below the upper sheet , acts like a diffuser. The gap between these two sheets traps the heat & does not allow it to flow to the shop floor.
