1 SkyPipeTM Day Light Harvesting A Natural Light Source
Brought to you by Eview Global Pvt Ltd

2 What is SkyPipeTM Day Light Harvesting
Day lighting is lighting an indoor space with windows and skylights that allow daylight into the building. This is chosen to avoid adverse effect of Static / over / under-illumination by artificial light. The amount of daylight received into an indoor space depends on the day light factor SkyPipeTM Day Light harvesting reduce artificial lighting energy by using fewer electric lights or dimming as daylight is present. Resulting to Power Saving.

3 How we react to Day Light
When we have excess day light we block it and switch on artificial lights. When we do not have enough daylight we switch on artificial light.

4 Day Lighting system – Advantages
Any modern natural day lighting system should:- Provide Natural Day Light minus the heat. Provide for air movement / circulation Gives all medicinal values of being under natural light like vit D etc.

5 The working SkyPipeTM Commercial/Industrial/Ware House Applications
SkyPipe is tailored made for each requirement of the area where it is to be installed. Dome collects and concentrates the ambience day light. Highly reflective tube delivers high light levels despite long tube or angles or overcast for max illumination with reflectance of over 95% Commercial/Industrial/Ware House Applications Can reduce total energy requirement appx by over 50%. Stylish diffuser diffuses light evenly in wider area

6 Quality of Light Optical diffuser gives uniform and broader light dispersion. Can deliver day light even in dark corners The system is Aesthetic and creates better ambience.

7 SkyPipeTM Can reach under false ceiling.

8 Wider reach without hot spots and UV
Can deliver light effectively through out the day even at low sun angles. Transparent sheet lights up area beneath the sheet and creates bright hot light spots. Blocks UV to a great extent. Transparent sheets

9 Almost zero maintenance
Avoids Roof top accidents SkyPipes are clearly visible from a distance. Transparent sheets gets camouflaged due to dust settled over it allowing roof top accidents. Almost zero maintenance Dust does not settle as it is hemi spherical and designed accordingly. Maybe cleaned occasionally with a dry cloth. Works well till the structure lasts. Very long life.

10 Minimal Heat Transfer SkyPipeTM has a static air column which reduces the heat transfer. Longer length tube further reduces heat transfer. The surface area of SkyPipeTM exposed to the Sun is very insignificant. Heat Insulation can be put from the inside to the roof which other wise not possible with Transparent sheets.

11 Other Products offered
SkyPipeTM Turbo Other Products offered Meets the need for Natural Light and air circulation. Ensures Effective and uniform Light and Air circulation. No power cost for Light and air circulation. Common roof opening for SkyPipeTM and turbo thus maintaining the strength of the roof. Effective in releasing hot air and fumes from the inside without maintenance. Water seepage and dust thru turbo fins will not enter the shed during very strong wind. Open able duct option in case cleaning required. Cost effective as no additional installation cost. 100% customized design as per the areas requirement.

12 SkyPipeTM Light Vent Installed on to window / side vents or puncturing the side wall. Even dispersion of light from 8 to 10 meters.

13 SkyPipe TM Roshni - CSR Lighting
Illuminating hutment with Roshni Provides pure white light. No heat transfer. Air vent for Cooking smoke release. Long life of about 10 to 12 yrs. Totally maintenance free.

19 Effect of Light on our body
Effects of light Morning Effects of light Night time and Sleep Onset Increasing light levels signals body clock, it should begin active cycle Melatonin and other night time hormones > endocrine system and blood stream Body clock responds by producing serotonin, adrenalin and cortisol, etc. Effects of light Daytime Body temperature drops as melatonin is released Level of these hormones rises, as well as temperature and metabolism Effects of light Twilight and Awakening By mid afternoon, body's metabolism has reached peak Effects of light Evening As darkness > twilight, body clock shuts down production of melatonin Daylight intensity diminishes, body clock signals pineal gland to convert It begins active cycle again. serotonin into melatonin > decrease body temperature Body is regulated thru dynamic lighting with the regulation of hormones

20 Human Benefits of Daylight
Human body functions are affected by patterns of light & dark. Specifically by blue light waves found only in daylight. Studies worldwide suggest natural dynamic light helps us maintain hormonal balance and provide us with likes of vitamin D etc and that productivity is enhanced in natural light, Daylight connects people with the natural environment outside, and people feel happier and less fatigued in natural daylight. Daylight is widely accepted to have a positive psychological effect on the humans. In recent years, work has taken place to recreate the effects of daylight artificially without much success.
