Building Information Modelling (BIM) | OpenBuildings

Integrate multiple disciplines – from Architects (AEC) to Electrical, Mechanical (MEP), and Structural Engineers – to successfully Design, Analyze, Construct, and Manage buildings of all types and scales. With OpenBuildings software, you can deliver sustainable, high-performance buildings faster and with ease.

  • Design buildings and facilities
  • Analyze building system performance
  • Collaborate across multi-discipline teams
  • Generate documentation and report


All Disciplines 

  • Design in 3D to explore ideas with free-form modeling 
  • Design in context with referenced reality models and point clouds 
  • Perform clash detection 
  • Produce lifelike renderings, visualizations and movies 
  • Apply company and project standards  
  • Exchange data in common formats (i.e. IFC, COBie, RealDWG, Revit Family RFA, and SketchUp SKP) 
  • Incorporate project documents, media, web links, and more with hypermodeling 
  • Easily manage data with bidirectional editing in Microsoft Excel 
  • Share project information with iModels 
  • Enforce production standards within a ProjectWise managed environment 
  • Automate coordinated drawings by controlling drafting styles and annotations 


  • Speed up design by using a catalog of walls, doors, windows, and furniture 
  • Manage floor definitions for reference planes and floor groups 
  • Define custom grid systems 
  • Manage spaces to ensure compliance with owner requirements 
  • Model custom design stairs and handrails 
  • Interactively design configurations of curtain walls 


  • Model detailed steel structures, trusses, bar joists, handrail, and ladder assemblies with ProSteel elements 
  • Model concrete and timber structures 
  • Reference a comprehensive library of international steel and concrete shapes 
  • Produce quantity reports and volume and weight analyses 
  • Share structural models and analysis using Bentley’s Integrated Structural Modeling (ISM) technology 
  • Exchange data with detailing applications using industry standards (i.e. CIS/2, and SDNF) 


  • Route multiple pipes simultaneously with different diameter, spacing, end type, insulation, and with manufacturer catalog 
  • Parametrically model HVAC, piping, and plumbing systems 
  • Define components, paths, and angles to be modeled automatically when completing connections in HVAC and piping systems 
  • Dynamically route pipe systems with slope applied or apply as a post process 
  • Create and configure air handling units using standard modules 
  • Size ductwork based on air flow, velocity, and friction rate 
  • Export designs to Trimble’s FabShop for fabrication 


  • Streamline lighting design using smart symbol arrangement tools that are aligned with ceiling grid and wall-mounted components 
  • Design electrical circuits and associate with lighting, power, or fire protection panels 
  • Automatically label components with user-definable labeling formats for switch designation, circuit numbers, and device IDs 
  • Model cable trays, baskets, conduits, and wireways 
  • Evaluate lighting level with a bidirectional interface with Relux lighting analysis 
  • Produce drawings and block diagrams, lighting, cable, and panel schedules based on user-definable templates 

Computational Design 

  • Define objects, assembly relationships, and dimensional constraints to capture design intent to explore a broad range of what-if scenarios 
  • Use visual programming techniques to create design solutions, manage dependencies, and orchestrate behaviors between design objects 
  • Use mathematical statements to control geometry and define dependencies between design objects 
  • Create reusable geometric assemblies extending the range of geometry with embedded intelligent behaviors 
  • Define input controls (i.e. sliders and law curves) to dynamically manipulate design components and propagate change within the design 
  • Play the design script forward and in reverse incrementally to visualize the design intent and behaviors of design relationships 

Energy Simulation 

  • Perform whole building energy analysis with analytical space models and conceptual mass models using industry-standard EnergyPlus 
  • Calculate design and satisfy building regulation requirements using industry-standard building load calculation methods (i.e. ASHRAE, PartL, and CIBSE) 
  • Reference a catalog of predefined standard HVAC system templates 
  • Calculate daylight factors using industry-standard Radiance engine 
  • Model surrounding buildings to simulate the effect of their shade on the design 
  • Create reports and charts for all aspects of building simulation including heating and cooling loads, LEED compliance, annual energy use, equipment sizing requirements, and CO2 emissions
