Dynamic Shading
Background Material: DH-II chapter 13 & 14 (to be released in 2016) | MIT lecture: Envelope Design
The goal of this assignment is to introduce dynamic shading system such as Venetian blinds and or switchable glazings to a daylight simulation and to evaluate the trade-off between glare control and access to daylight. To do so, calculate the spatial daylight autonomy distribution for the space using a simulation environment such as DIVA/Daysim. A detailed video tutorial, describing the simulation setup, is provided under DIVA Tutorial 04 - Dynamic Shading. The table below shows an example output from this exercise. Adding Venetian blinds to the South-facing space in Boston from the previous glare exercise eliminates discomfort glare (top row) but reduces the daylight area (transition from yellow to blue) from 43% to 34% of the floor area.
