Course Description

This course will introduce two important and powerful topics that can be explored using the OpenStudio ecosystem – authoring of custom ‘measures’ and the numerical quantification of simulation related uncertainties. Participants will learn the fundamentals of OpenStudio measure authoring, and will gain an understanding of how the flexible OpenStudio architecture can be manipulated to accomplish simulation goals. Methods for using OpenStudio tools to determine simulation related uncertainty will be shared, along with examples studies.
