If you selected 'Mixed Use' on the previous question, what are the different uses?


List the investigations questions that drove your analysis process.

What’s the best glazing configuration that would optimize the mountain views, minimize glare and maximize good daylighting? What’s the spacing of pergola members to minimize direct sun glare inside the classroom till 2pm. How deep would the light penetrate with different glazing configurations?

How was simulation integrated into the overall design process?

A conceptual design was created to optimize the views on site. A deep overhang was part of the initial rendering by Design Architect. During late SD and initial DD, question was raised about the negative impact of deep overhang on the daylighting contribution and ways to optimize the solution. Analysis was done to show the current quality of light and an alternative was proposed with clerestory and less deeper shade. When the alternative was rejected, it was decided to optimize the current deep shade to let some penetration of light but block the direct glare on the glazing during school hours. The final alternative involved creating a pergola with varied spacing of its members to reduce material, maximize indirect daylight while minimizing direct sunlight falling on the glazing.

How did you set up the simulation analysis and workflow?

The geometry was created in Ecotect and daylighting was analyzed using radiance and Daysim.

How did you visualize the results to the design team? What was successful about the graphics that you used to communicate the data?

The concept was explained with simple diagrams. Different options were analyzed using horizontal and vertical illumination planes to understand the impact.

Most importantly, what did you learn from the investigation? How did simulation and its outputs influence the design of the project?

Is there anything else you'd like to mention? This can be in terms of your case study, this form, or suggestions for improving the submission process in general?
