Rorschach Shadow Diagram
We’re developing a set of Grasshopper user objects to generate sun study diagrams using the DIVA sun vector component. This post focuses on the overshadowing diagram, a powerful metric which offers comprehensive analysis for point of interest shading (more info). The diagram can be used for early site studies to consider shading based on existing context. It also demonstrates the impact of vegetative shading strategies, particularly in deciduous climates (during the winter, leafless trees will allow light to enter the building for warmth; during the summer, the regrown leaves will shade the building to ease the load on cooling systems).
Med Mart 3: Daylighting the Atrium
In this post, we move into the interior to talk about how we are using daylight inside the building. A major feature of the design is a large central atrium with a four-story structural glass wall facing the Mall. While providing a good amount of natural light to the atrium, this entirely glazed edge also contrasts greatly with the three other non-glazed walls. We knew we needed a strategy to more effectively balance the light levels throughout the space, and our goal was to achieve that with natural lighting.
Stage Lighting with LEDs, Arduino, & Firefly
We used 10 high-intensity LEDs to light a 1:24 scale model of a studio theater. The LEDs were wired to an Arduino micro-controller and programmed using the Firefly components for Grasshopper. All 10 LEDs can be individually controlled from a Grasshopper definition or wired together (in GH) to form banks of lights. The result is a computer-controlled mini theatrical lighting system on the cheap.
