Car Showroom Indore

This particular showroom is located in Indore , surrounding commercial building which are tall and very close to each other. This showroom was chosen as the showroom does not get even direct light from sun untill 2PM in the afternoon.

All the pictures seen are taken at 1PM and still there is a lack of proper illumination inside the showroom and thus makes for a compelling site.

Site Analysis

8AM MArch No sun exposure at 8am

12pm MArch Minimal sun exposure at 12pm

Site Analysis shows the buidling is facing west which makes it not have any exposure untill 2PM in the afternoon.

The Purpose of the site study was to study pattern of the sun exposure and how does it change thoughout the day. This study helped me pick the intervention area as roof.

4PM MArch

Good sun exposure at 4Pm

Site Simulations There is not enough light due to low lux level There is enough lux level for a human to see properly

The simulations clearly show the lack of sun penetration inside the building and uptill what extent.

The tool used for the simulations is velux daylight visulalizer

4PM Mar

8AM Mar

The LIght penetration is very less

there is no light entering the showroom

Anual Daylight factors Daylight factors refers to Inside lux level compares to outside and this should be always in the green zone for well litt environment

Conclusion: Thus i went forward with idea of bringing in light which can be complimentary to the artificial lighting

Case Studies The Anidolic mirror systems Typically, light is captured with a compound parabolic collector (CPC) or elliptical collector (CEC) mounted on the exterior wall. These mirrors provide a wide and even collection pattern. The vertical capture angle approaches 90 degrees, from the horizon to the vertical plane of the supporting wall. An even capture pattern alleviates the need for a solar tracker: a permanently fixed anidolic collector remains effective at any time of day. This is the High Museum of ArtÆs Wieland Pavilion and Anne Cox Chambers Wing , designed by Renzo Piano

Light Redirections Sydney towers have huge set of mirrors which redirect sunlight where sun usually cant reach due to these massive skyscrapers. So there is set of calibereated mirrors to actually redirect and guide the light towards that area and indeed redirect sunlight. The project is sydney towers by Jean Nouvel.

I tried usng both of these together so i could use it in my showroom

Process:

Track based horizontal rotation for one axis

With the Inspiration from renzo Piano and reseach on light collectors , i tried a f rescel lens collector and a tapered opening for the light to diffuse , but the size of the showroom and the orientation of the building did not make this idea go any further, But it made me aware of the problem of hotspots and concentration of light in one place is a glare so i began thinking of distribution of light and diffused light.

Process ( using skylights)

This step was very curcial as in my final design i incorporated the same distribution principle and if has worked very well in distribution and providing diffused light throughout the showroom

Skylights skylight have been used since a long time to bring natural light inside and establish a connection to the outside and thus i sifted my attention towards skylight as a passive technique and making it much more efficient. The light redirection concept came into play here where i used a parabolic reflector to catch the morning sunligh and redirect it inside my showroom. which is controlled by audrino

Inferances from making a physical model Prism shape works for the skylight but cannot combat the 12pm direct sun exposure . we can only use two light sensors for the performative variables.

Flaps move when i cover one of the sensor

Process : Mechanism

Here my design came to a rest and mechanism was also working , after this we were told me make technical drawings of the same and post intervention simulation to back up our design development.

POst- Simulations There is not enough light due to low lux level There is enough lux level for a human to see properly

The simulations clearly show the diffrence in light penetration and the quality of diffused light the intervention brings in.

4PM Mar The LIght penetration is very good

12pm

Mar there is good amount of light entering

Anual Daylight factors Daylight factors refers to Inside lux level compares to outside and this should be always in the green zone or above for well litt environment

JAN

Conclusion: DEC

This anual simulation clearly states that the intervention is bringing in enough light to cut down the usage of artificial lights.

Just Skylight without new light pipe The redistribution of the light though reflection was a sucess as seen in the simulation below the quality of light with the light tube is much better and diffused. The skylight brings in light though reflector but its harsh.

7AM The LIght penetration is very good

7am( Overcast) there is good amount of light entering
