BEEP had organized a Design Competition for External Movable Shading to create innovative, India-specific designs and solutions. The project has provided technical assistance to the winning designs in the form prototype development and testing to make them finished articles which can be launched in the market.
The design competition was conducted for 2 categories named after the most common application in buildings:
- Residential Sector (simple shading system): The shading systems will block all solar radiation (heat as well as light). These are expected to be simple, low cost solutions which will find wider applications in residential buildings.
- Commercial Sector (shading and day-lighting system): The shading systems will block the heat component of solar radiation but will provide effective natural day-lighting. These should be sophisticated mechanisms (can include sensors and automation) which find more application in commercial office buildings.
The competition was structured in two stages for both sectors, namely, Design Stage (Stage 1) and Mock-up Stage (Stage 2).
At the design stage, the focus was primarily on creative and innovative designs and a list of design were finalized. During the mock-up stage, shortlisted designs were asked to develop working mock-up models to test their functionality and effectiveness.
Due importance was given to both aspects while deciding the final winners and winners were decided after completion of the mock-up stage.
Objectives of the Design Competition:
The objective of this competition is to help bring the India-centric external movable shading system designs to the domestic market so that architects, product designers, HVAC engineers and others to use these systems/concepts in the buildings that they are associated with.

What are External Movable Shading Systems
External Movable Shading Systems are installed on the windows and glass facade of buildings which dynamically control the solar heat ingress and the visual light transmission. Controlling the solar heat ingress has a significant impact on the cooling/HVAC load of the buildings. Sophesticated systems also provide natural day-light control.
Why External Shading instead of Internal Shading
The Solar Heat Gain Coeffiecient (SHGC) of internal blinds is more than 40% while that of a external shading system is less than 12%. The diagrams below demonstrate the reason for this low SHGC and the significance of external shading systems.
|Internal Blinds||External Blinds|
|As the shading system is behind the glass pane, the heat enters the building and the Solar Heat Gain Coefficient (SHGC) is more than 40%||As the shading prevents a significant proportion of heat from entering the building, the SHGC can be reduced to less than 12%|
Types of External Movable Shading Systems

1. Why External Movable Shading Systems
External Movable Shading Systems provide reduction in solar heat gain through building facades and thereby can significantly reduce the cooling load. Sophisticated systems also have the ability to control day-lighting and provide a more natural habitat indoors.
2. Why the design competition
BEEP has identified External Movable Shading Systems as one of the innovative building energy efficiency technologies which is ideally suitable for India’s predominantly composite climate. Despite it being a popular solution in Europe, this concept is fairly unknown in India. The competition has two motives. The first motive is to instigate architects, designers, engineers as individuals, team, or firms to develop creative, indigenous products suitable of Indian climatic conditions. The second motive to popularize this concept among this group so that they apply this technology in the buildings they design/build.
3. Why two categories of buildings
Because Residential and Commercial are the two prominent electricity consuming building sectors and are inherently very different in terms of design and energy demand profile. Also, because expectations and paying capabilities of users in each category is vastly different.
4. Why two stage competition structure
The competition has been structured into two stages: Design Stage and Mock-up stage. It has been done so as each stage has a definite goal.
The design stage aims to provide the designer with full creative freedom to build innovative designs which can achieve desired performance and functions.
The mock-up stage will evaluate the practicality and real world operability of the designs.
