Purpose & ObjectivesProblem: Building energy analysis has historically been costly and producesuncertain results depending upon practitioner skill and available input data.New tools are expensive to produce and aren’t well integrated.Impacts: OpenStudio isDOE’s platform for rapid,collaborative development ofenergy analysis applications.It is being used by the labs,EEB, the private sector, andothers to create market facingtools.2 Building Technologies OfficeEnablingAnalysis forEmergingTechnologiesEasy-to UseTools forPractitionerssimuwattMobileAuditing ToolUtilityFocusedWeb ToolsOpenStudio Software Development Kit (SDK)Broad Market PenetrationProject Focus: The projectcross cuts ET and CBI to spuradoption of new and existingEE technologies by makingtools available to a widerange of decision makers.Market Facing Modeling and Analysis ToolsModeling Engines (EnergyPlus, Radiance, Others)Modeling Expertiseeere.energy.gov

Software TechnologyApproach: Rapid application development:––––Cross platform, multi-language supportEasy to write web apps for energy modelingMaximum code reuse for low costHighly efficient, automated model construction3 months todevelop Open Source:– Why reinvent the wheel?– Remove barriers for adoption– OpenStudio is creating a community2 months todevelop Interoperability:––––Multiple simulation enginesBIM (gbXML, IFC)Title 24 compliance engine (SDD)Sandia’s DAKOTA Library for analysis2 weeks toprototypeKey Issues: Full coverage of all EnergyPlus objects still in progress – a moving target Need modularized build process for lighter apps that don’t require everything in OpenStudio Heavy adoption is putting additional pressure on team for user and developer support3 Building Technologies Officeeere.energy.gov

Software DevelopmentApproach: Development team uses an “agile” software development process– Formal task and bug tracking systems– Automated nightly software build, test, and dashboarding system– Formal processes for design document and code reviews Frequent vetting of UI concepts and workflows with external stakeholdersDistinctive Characteristics: Flexibility to quickly produce newdesktop, mobile, and web tools thatare easily integrated with oneanother Agile process allows focus tochange as new requirements emerge Rigorous approach to creatingsoftware for the marketplace - not aresearch project Open, collaborative approach tosoftware development that welcomespartners from other labs, institutions,and the private sector.4 Building Technologies eere.energy.gov
