SkyPipeTM Day Light Harvesting A Natural Light Source
Brought to you by Eview Global Pvt Ltd
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
What is SkyPipeTM Day Light Harvesting
SkyPipeTM Day Light harvesting reduce artificial lighting energy by using fewer electric lights or dimming as daylight ispresent. Resulting to Power Saving.
How we react to Day LightWhen we have excess daylight we block it and switchon artificial lights.
When we do not haveenough daylight weswitch on artificial light.
Any modern natural daylighting system should:-
1. Provide Natural Day Light minus the heat.
2. Provide for air movement / circulation
3. Gives all medicinal values of being under natural light like vit D etc.
Day Lighting system – Advantages
The working SkyPipeTM
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%Stylish diffuser diffuses light evenly in wider area
SkyPipe is tailored made for each requirement of the area where it is to be installed.
Commercial/Industrial/Ware House ApplicationsCan reduce total energy requirement appx by
over 50%.
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.
SkyPipeTM Can reach under false ceiling.
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
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.
Minimal Heat Transfer
1. SkyPipeTM has a static air column which reduces the heat transfer.
2. Longer length tube further reduces heat transfer.
3. The surface area of SkyPipeTM
exposed to the Sun is very insignificant.
4. Heat Insulation can be put from the inside to the roof which other wise not possible with Transparent sheets.
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.

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