The northern facade of the building is towards the right of the section above. As you can see it is cut into the cliff face. Therefore it is not available for the penetration of natural sunlight. As buildind usually rely on this northern aspect, it was obvious that something had to be done to ensure adequate levels of natural light could enter the building to increase its sustainability. Therefore more research was conducted in regards to how sunlight can inform the capture of sunlight in difficult circumstances. My research led me to the window plant (fenestria Aurantica) as shown below.
This plant has a limited syrface area available for sunlight penetration due to it occuring predominately below the ground to maintain a cool temperature. Only the tips of the plants appear out of the soil. These tips are transparent which wllow sunlight to enter the long hollow tubular leaves of the plants. Along these tubes are a series of oxalic acid crystals along which the sunlight is filtered until it is focused onto the chlorophyll where photosynthesis occurs. This concept has been applied to my building through a series of rooftop capsules which contain a series of timber batons arranged in a cirulcar fashion. On the inside of these batons are reflective mirror surfaces which reflect the sunlight until it hits the photovoltaic cells at the bottom of the structure. The capsules are indented into the green roof as shown below to allow site users to drop below the roof surface and achieve views into the sports facilities and museum spaces depending upon where the capsule is located. This concept will not only provide much of the natural lighting and energy required for lighting within the building but will provide much of the interaction desired between the green roofs and the internal spaces. These spaces are also clearly shown in the final section which also clearly shows the relationship between the roof, capsule and internal spaces.
