Simulation Studies | (MSSD) Carnegie Mellon University
Tools: Rhino, Grasshopper, Climate Studio & Ladybug Plugins| Type of Work: Teamwork
This study aims to identify how basic principles of photometry and optics can be used to generate and evaluate a comprehensive set of daylight harvesting design strategies for building spaces. Acquire necessary skills (Rhino-Grasshopper ClimateStudio with Radiance illumination algorithm) to systematically apply a range of analytical methods for the quantification of a “luminous environment” within an architectural space.
Case Building in Los Angeles
Space Assignment and Baseline Furniture Layout
We have continued the same base case model as we studies for the ‘Solar radiation‘ studies located in Los Angeles, CA. Here we rotated the building 90 degrees clockwise so that the initially East facing glazing is now facing the true South. Besides the building rotation, we also placed the furniture in the case building to simulate.
The existing design of the building is experiencing high ASE, glare, and illuminance issues. Thus, to control
the natural daylight and create visual comfort for the office environment we did various design iterations by changing the indoor materials for 'Window glazing', 'Skylight', and 'Internal wall'.
