OpenStudio is a suite of free and open-source software applications for building energy analysis used in building information modeling. [1] OpenStudio applications run on Microsoft Windows, Macintosh, and Linux platforms. [2] [3] Its primary application is a plugin for proprietary SketchUp, that enables engineers to view and edit 3D models for EnergyPlus simulation software. [2] [4] [5] [6] [7] [8] [9] [10]
OpenStudio was first released in April 2008 by the National Renewable Energy Laboratory, a part of the U.S. Department of Energy. [8] [11] NREL reports an average of 700 OpenStudio downloads per month. [8] Google's strategist for SketchUp, remarked that "OpenStudio is lauded around our office as one of the most complicated plug-ins ever written for SketchUp". [8]
OpenStudio was designed to work with SketchUp, because many architects already use SketchUp for building designs. The integration allows architects to analyze a design's energy performance before beginning construction. [12]
The first private organization selected by NREL to conduct OpenStudio courses was Performance Systems Development, a New York–based training institute. [13] Courses will be conducted for building professionals, software developers, and utility administrators. [13] Harshul Singhal and Chris Balbach teaches OpenStudio to the engineers on regular basis under this contract. From May 2018, Harshul Singhal started teaching OpenStudio through The Energy Simulation Academy (TESA) which is another private organization selected by NREL to conduct such training. [14]
OpenStudio includes a Sketchup Plug-in and other associated applications:
The OpenStudio Sketchup Plug-in allows users to use the standard SketchUp tools to create and edit EnergyPlus zones and surfaces. It allows SketchUp to view EnergyPlus input files in 3D. The plug-in allows users to mix EnergyPlus simulation content with decorative content. [3]
The plug-in adds the building energy simulation capabilities of EnergyPlus to the SketchUp environment. Users can launch an EnergyPlus simulation of the model and view the results without leaving SketchUp. [3]
The Plug-in allows engineers to:
Computer-aided design (CAD) is the use of computers to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software help protect products and inventions when used in patent applications. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The terms computer-aided drafting (CAD) and computer-aided design and drafting (CADD) are also used.
Autodesk, Inc. is an American multinational software corporation that provides software products and services for the architecture, engineering, construction, manufacturing, media, education, and entertainment industries. Autodesk is headquartered in San Francisco, California, and has offices worldwide. Its U.S. offices are located in the states of California, Oregon, Colorado, Texas, Michigan, New Hampshire and Massachusetts. Its Canada offices are located in the provinces of Ontario, Quebec, and Alberta.
Geologic modelling,geological modelling or geomodelling is the applied science of creating computerized representations of portions of the Earth's crust based on geophysical and geological observations made on and below the Earth surface. A geomodel is the numerical equivalent of a three-dimensional geological map complemented by a description of physical quantities in the domain of interest. Geomodelling is related to the concept of Shared Earth Model; which is a multidisciplinary, interoperable and updatable knowledge base about the subsurface.
COLLADA is an interchange file format for interactive 3D applications. It is managed by the nonprofit technology consortium, the Khronos Group, and has been adopted by ISO as a publicly available specification, ISO/PAS 17506.
The National Renewable Energy Laboratory (NREL) in the US specializes in the research and development of renewable energy, energy efficiency, energy systems integration, and sustainable transportation. NREL is a federally funded research and development center sponsored by the Department of Energy and operated by the Alliance for Sustainable Energy, a joint venture between MRIGlobal and Battelle. Located in Golden, Colorado, NREL is home to the National Center for Photovoltaics, the National Bioenergy Center, and the National Wind Technology Center.
SketchUp is 3D modeling software that is used to create and manipulate 3D models. It is used in architecture and interior design.
Navisworks is a 3D design review package for Microsoft Windows.
VisIt is an open-source, interactive parallel visualization, and graphical analysis tool designed for viewing scientific data. It can visualize scalar and vector fields on 2D and 3D structured and unstructured meshes.
Specialized wind energy software applications aid in the development and operation of wind farms.
GIMIAS is a workflow-oriented environment focused on biomedical image computing and simulation. The open-source framework is extensible through plug-ins and is focused on building research and clinical software prototypes. Gimias has been used to develop clinical prototypes in the fields of cardiac imaging and simulation, angiography imaging and simulation, and neurology
RELAP5-3D is a simulation tool that allows users to model the coupled behavior of the reactor coolant system and the core for various operational transients and postulated accidents that might occur in a nuclear reactor. RELAP5-3D can be used for reactor safety analysis, reactor design, simulator training of operators, and as an educational tool by universities. RELAP5-3D was developed at Idaho National Laboratory to address the pressing need for reactor safety analysis and continues to be developed through the United States Department of Energy and the International RELAP5 Users Group (IRUG) with over $3 million invested annually. The code is distributed through INL's Technology Deployment Office and is licensed to numerous universities, governments, and corporations worldwide.
Building performance simulation (BPS) is the replication of aspects of building performance using a computer-based, mathematical model created on the basis of fundamental physical principles and sound engineering practice. The objective of building performance simulation is the quantification of aspects of building performance which are relevant to the design, construction, operation and control of buildings. Building performance simulation has various sub-domains; most prominent are thermal simulation, lighting simulation, acoustical simulation and air flow simulation. Most building performance simulation is based on the use of bespoke simulation software. Building performance simulation itself is a field within the wider realm of scientific computing.
C3D Toolkit is a proprietary cross-platform geometric modeling kit software developed by Russian C3D Labs. It's written in C++. It can be licensed by other companies for use in their 3D computer graphics software products. The most widely known software in which C3D Toolkit is typically used are computer aided design (CAD), computer-aided manufacturing (CAM), and computer-aided engineering (CAE) systems.
Kubity is a cloud-based 3D communication tool that works on desktop computers, the web, smartphones, tablets, augmented reality gear, and virtual reality glasses. Kubity is powered by several proprietary 3D processing engines including "Paragone" and "Etna" that prepare the 3D file for transfer over mobile devices.
Sensitivity analysis identifies how uncertainties in input parameters affect important measures of building performance, such as cost, indoor thermal comfort, or CO2 emissions. Input parameters for buildings fall into roughly three categories:
Flowmaster Ltd. was a leading British Engineering Simulation Software company based in Towcester, UK. Its flagship 1D CFD product, also named ‘Flowmaster’, was first released commercially in 1987 although initial versions went back to the early 1980s having originated from BHRA, the not-for-profit British Hydromechanics Research Association, later to become the BHR Group.
IDA IndoorClimate andEnergy is a Building performance simulation (BPS) software. IDA ICE is a simulation application for the multi-zonal and dynamic study of indoor climate phenomena as well as energy use. The implemented models are state of the art, many studies show that simulation results and measured data compare well.
