Conceptual Design

How was simulation integrated into the overall design process?

The simulation was integrated at a very early design phase stage to compare various massing and suggest to the client a road map to reduce energy use and solar radiations on the building scheme and to present the relative impact of different energy conservative measures at the whole building scale between passive and active measures. A parametric simulation was used at the beginning internally before summarizing the findings into a simple graphic. More than 4000 simulations were computed, used as an intermediate step. (screenshot below)

How did you set up the simulation analysis and workflow?

The geometry was modeled in Open Studio. The parametric energy analysis was ran with jEplus. The outputs were generated by Adobe Photoshop, Excel, Power Point.

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

The results were shown to the design team on a power point explaining the inputs, outputs and magnitude impact of the energy conservative measures.

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

This is a joint effort of 4 people: - Olivier Brouard, Sustainability Engineering Team Leader - Shaily Rungta, Building Performance Analyst - Neil Katz, Daylighting Performance Specialist - Stephen Ray, CFD Specialist - Luke Leung, MEP Engineer Team Leader - Jason Kirkpatrick, Building Performance Analyst
