SIMULATION PROCESS SECTION
To understand the magnitude impact of design decisions very quickly and simultaneously.An interactive engaging exploration tool reading pre-run simulations. Leverages high multidimensional results of large-scale dataset.
- Architect - Internal Sustainability Personnel
- Conceptual Design
The simulation was integrated at concept design to allows designers to simultaneously see the impact of design solution on multiple performance criteria. This tool was used as a way to run a live energy model and influence the design process directly before decisions were made. Customizable and optimized for storytelling. Provides real-time feedback to Design Team to highlight major findings.
The graph highlights all the possible permutations computed for the variable studied. The baseline is based on the ASHRAE 90.1 2007 standard [Appendix G] orienting the building at a true North angle of 45°. The results were shown in a HTML page directly to the design team. The architects used the selectors to filter through the parameters and figured quickly the path to get to their goal.
I wished I could have added the upfront cost of the design variables to weight in the return on investment and payback period.
