The Project

As part of a campus masterplan in the northeastern part of Houston, this building had a fixed orientation. Using a single day of peak solar load, the designers efficiently experimented with a range of glass to wall ratios - from 10 % to 90% - to see the implications of their design decisions in real-time. The designers then exported the data calculations to FenestraPro Snapshots to comparatively analyse the results. In consideration of Prescriptive Energy Codes IECC-2015 and the threshold where shading becomes beneficial, FenestraPro graphically demonstrated the optimal glass-to-wall ratio per façade and provided detailed solutions.

Carried out by a Building Performance Analyst as part of the Higher Education design team at PageThink, this exercise using FenestraPro led to data-driven decision-making. This investigation into glass-to-wall ratio, which can often take days, was carried out in a matter of hours and informed the team of limits and opportunities of varying glazing solutions for each façade.

FenestraPro gave us rapid and comprehensive feedback for a competition proposal that we would have otherwise not run. The ability to parametrically generate windows and shading was a huge time saver, which enabled us to demonstrate a rich level of detail within the competition deadline.

Because of FenestraPro’s instant feedback, we finally have a tool that works well with our performance-based design workflows, which are always iterative in nature.
