Daylight Harvesting Technology

In News 

Recently ,Skyshade Daylights Private Limited – the only Start-up company in India for Daylight Harvesting Technologies signed an MoU with Technology Development Board.

• TDB (Technology Development Board) is a statutory body of the Department of Science & Technology.

About 

• The Ministry of Science & Technology will give Rs 5 Crore of the 10 Crore project to Skyshade company for developing new technologies for basement illumination on a 24×7 basis. 
• The unique start-up is engaged in roots starting with design & build operations of large skylight domes for building atriums and solar thermal technologies.
• The start-up has also come up with two more innovative solutions comprising:
  • Human centric-climate adaptive building facades
  • Central integrated daylighting system
    • The two above mentioned systems will give a new horizon to the daylighting. These innovations are easily affordable, adaptable and economically viable
• The company has proposed a complete solution for Daylight Harvesting through their technologies to reduce carbon footprint and improve the building energy efficiency. 
• The company aims to create Green & Net zero buildings and to participate and contribute in national missions under the National Action Plan on Climate Change (NAPCC).

What is Daylight Harvesting Technology?

• Daylighting is basically bringing natural sunlight inside the rooms. 
•  Daylight Harvesting is one of the most advanced techniques used in sustainable lighting designs for contemporary buildings.
•  It automatically adjusts the brightness of light in conjecture to the amount of light available in that space.
• The solar energy spectrum has 45% energy as visible light and this can be used to harvest building illumination for about 9-11 hours a day. 
  • The Technology used is completely indigenous, economically viable and easy to deploy and needs minimal maintenance with longevity. 
  • Moreover, the proposed technologies, harvest huge quantities of sunlight for a building and make available for building illumination which reduces electrical lighting energy consumption by 70-80%, besides reducing air-conditioning (cooling load) consumption.

Benefits 

• The renewable energy sector in India is expanding with the ever-increasing need of energy. 

• Lighting is a fundamental requirement of daily life. Daylight is available universally and it is a very clean and cost-efficient source of energy. 
  • Meeting energy requirements during the day by using daylight harvesting technology will contribute immensely to meet one of the commitments of the five nectars of “PANCHAMRIT” i.e., to make India a Net Zero emission country by 2070. 
• India’s targets are set – an ambitious target to achieve a capacity of 175 GW of its energy requirement from renewable energy sources by the end of this year and further, committed to achieve 500 GW by 2030. 
  • The daylight harvesting technology will be the next step towards a sustainable future.
