Explanation:

Recently, the Energy and Resources Institute(TERI) in partnership with the Department of Science & Technology has developed an external shading system named “ShadenSmart” under the Habitat Model for Efficiency and Comfort Project.

About ShadeSmart

• External shading devices are not common in modern buildings, which are mostly glazed or buildings with curtain walls.
• The shading systems are usually permanent structures, posing challenges such as maintenance, obstruction of views, architecturally not meeting the aspirations of the client, and so on.
• In contrast, ShadeSmart changes its configuration depending upon the Sun’s position.
• For example, when the Sun is in the East direction, East façade windows will be shaded, once the Sun is in South orientation during noon ShadeSmart configuration on East changes to provide unobstructed external views and glare-free daylight.
• This technology will help to bring inside the buildings more daylight with less heat, thus making occupants comfortable and also more productive and healthy.
• In the international market, many movable shading devices are available, however, since ShadeSmart is locally produced in India, it becomes an economically viable energy-efficient solution which every building may integrate in order to achieve energy efficiency.
• Radiant Cooling: It is where cooling is achieved through radiant heat transfer, as against regular convective air conditioning. This technology is efficient and gives better quality of thermal comfort.
