OpenStudio 0.11.0 is now available for download from the OpenStudio website. This OpenStudio release focuses on extensions to the SDK to enable a user-configurable parametric tool. The Parametric Analysis Tool (PAT) lets users modify a baseline OpenStudio model using OpenStudio measures to produce design alternatives.
OpenStudio measures are specially formatted Ruby scripts and accompanying files for modifying energy models in OpenStudio or EnergyPlus format. A small library of measures is included in the installer; more measures are available for download from the Building Component Library, and users can create their own measures by following the Measure Writing Guide. In PAT, modifications to the baseline energy model are specified by selecting a measure and setting its argument values. Mutually exclusive choices (e.g. alternative values of the South façade window-to-wall ratio) are typically placed in a measure group to ensure that a design alternative’s measures do not conflict with or overwrite each other. Design alternatives are specified by choosing 0-1 measures from each group. Users can debug their measures and other simulation steps by reviewing the detailed information on the simulation run tab. Upon successful simulation, summary energy metrics for each design alternative are reported on the results tab, where the final models may also be opened in the OpenStudio Application.
OpenStudio 0.11.0 supports EnergyPlus 7.2.
