Model scale: 1 / 75
I decided to make a 1/75 scale model of my final project to check how my design worked in reality. My intention was to present a complete final project because I wanted it to be a good personal introduction to my professional future.
I took some photographs of the model. It was very important to check the quality of the natural light inside the building and especially in the basket ball court. The players have to be comfortable, so it is necessary to get an homogeneous intensity of light. A very bright area next to a dark area would be a bad solution. In the same way, the materials used should be a light colour to avoid the contrast between the windows and the walls.
I designed eight skylights (2,8 x 20 meters) on the roof of the basketball court, which were made with frosted glass to diffuse direct light landing on the sports ground.
The west facade of the basketball court was made with a ventilated double skin U-profile glass, to avoid the direct light inside the building and to produce an homogeneous light during the day. At night there were some LED lights in between the double glazing which lighted the wall and the nearby areas. There were also some windows, which allowed the people walking through the park to see what was happening inside the building and at the same time allowed the players to see outside .
The model was built to check all these aspects. I put the model on the roof of my house, an eight floor building, ensuring that no trees or close buildings would block the natural light and took photographs over the day.
The idea was to take one picture per minute from daybreak to sunset. I began on the 25th of May at 5:56 am and finished at 21:55 pm I took almost 1000 photographs to create 25 pictures per second video .
The result it is an interesting video. In the morning, we see how the model becomes brighter over a very short period and then suddenly the first sun rays appear. Then follows a long period where we see the shadows move from the left to the right and the sun rays crossing the sky lights and the windows until they reach the playground and the walls. It is nice to see also how the colour of the light changes during the day. At the end the darkness increase quickly and the video ends.
