Dr. Wassim Jabi, Senior Lecturer develops an EnergyPlus/OpenStudio plug-in for DesignScript

Dr. Wassim Jabi, in collaboration with Autodesk and the U.S. National Renewable Energy Laboratory (NREL), has developed the DSOS plug-in to analyse the energy use of a parametrically designed building using Autodesk DesignScript and the U.S. Department of Energy (DOE) EnergyPlus software through the use of the OpenStudio Software Development Kit (SDK).

OpenStudio is a collection of software tools, developed by NREL, to support whole building energy modelling using EnergyPlus and advanced daylight analysis using Radiance. OpenStudio is an open source project to facilitate community development, extension, and private sector adoption. OpenStudio includes graphical interfaces along with an SDK.

Dr. Jabi's DSOS plug-in exposes many of these services in scripts, handling most of the process of sorting, labelling, and otherwise abstracting a model into OpenStudio’s specifications. To generate an approximate analysis, a scriptwriter simply needs to specify the building’s location through a weather file, specify what days and conditions to simulate, its general program (architectural use), and a non-manifold geometry representation of the form. Results can be visualised in a multitude of ways including colour-coding the 3D model itself.
