A large percentage of the south façade for my thesis project required protection from solar heat gains in the summer. Using concepts from earlier Grasshopper definitions, a new definition was developed to:
- Generate different densities, thus changing visibility based on interior needs
- Provide adequate shading
- Continue the concept of shifting lines in the articulation of the façade
The Facade that the louver system will be used on contains multiple functions within, including public spaces such as lounges and corridors and semi private spaces such as classrooms and lecture halls. Having an all glass facade for all these spaces would not work functionally or environmentally.
The definition solves these problems by expanding and contracting the density of individual louvers based on placement of attractor points. As the louver density increases, the individual louver depths thin out, maintaining even shading. The louver system can be generated on any wall imported into the definition allowing for quick testing and analysis.
I brought the louver system into Ecotect to test out the performance of the wall in reduction of solar radiation. Multiple louver systems were looked at including high densitie systems, medium density systems, and low density systems. These systems were also compared to a traditional system.
