Question-and-Answer Resource for the Building Energy Modeling Community

We deliberately avoided adding the ability to create full combinatorial analyses in PAT because such problems blow up quickly. These are typically intractable using local CPU resources, and we were concerned that people using the EC-2 capability might not realize the expense they could incur. PAT was meant as an introduction to parametric analysis for practitioners more accustomed to manual creation of design alternatives.
That said, the team has developed a spreadsheet-based workflow that allows you to move beyond PAT's deliberate limitations to perform factorial analysis, sampling, and optimization problems. Learn more about this capability here.

We would like to better integrate the current PAT and spreadsheet workflows, eliminating the need to use the command line, but that's not on the roadmap for this year.
