3. BIM (Building Information Modelling) A process of generating and managing building data during its life cycle. It can use three-dimensional, real-time, dynamic building modelling software to increase productivity in building design, construction and maintenance period. “ A model-based technology linked with a database of project information” according to American Institute of Architects What is BIM?

4. Multiple models into a “composite model” What is BIM? Architectural Model Energy Model Compliance Model Structural Model Cost Model Electrical Model • Graphical information • -3D objects visual in the model Composite Model Mechanical Model BIM (linked with phasing, sequencing, construction schedule) • Non-graphical information • - Performance data Plumbing Model Other Model • Linked information • - Schedule & cost information

6. Conventional design process Building design process Master Planning Concept Design Schematic Design Detailed Design Completion In use Planning staff, clients community member Architect & clients Mainly architect , structural engineer & clients Mechanical, electrical, & civil engineers Contractors, construction manager, commissioning authority, cost estimator Users A linear design process Performance analysis tool

7. Conventional design process Construction Tender documentation Detailed Design Schematic Design Concept Design Project start Effort Consultation & Engagement Schematic Design Detailed Design Construction Documents Construction Time completion

8. Integrated design process Key elements of integrated design process Building design process • Inter-disciplinary collaboration between architects, engineers, cost consultants and facility managers from the beginning of the design process • Discussion of the various important performance issues and the establishment of a consensus on this matter between client and designers • Budget restrictions applied at the whole building level, with no strict separation of budgets for individual building systems. • Involvement of specialists (e.g. energy engineering, energy simulation, daylighting, comfort) • Data sharing • Clear articulation of performance targets and strategies, to be updated throughout the process by the design team • Documentation and transparency of design decisions Effort Traditional Schematic Design Detailed Design Construction Documents Construction Time

9. Integrated design process Predictive/incentive modelling Completion Performance analysis tool Compliance modelling • A multi-disciplinary design team • Landscape architect • Ecologist • Architect • Energy specialist • Structural engineering • Civil engineering • Mechanical engineer • Electrical engineer • Plumbing engineer • Other specialists(fire, acoustics, daylighting, controls, etc.) • Facility manager • Contractor • Construction manager • Cost estimator process Load/Energy modelling Detailed design In use Measurement & verification A multi-disciplinary design team design Schematic design Master planning Building Building Parametric modelling Mater plan modelling Concept design Conceptual modelling

15. Model Merge • Changes to Imported Geometry are Updated in <VE> Model • Without Overwriting Input Data Original Model Room Data New Model Room Data

16. What does software does IES work with? Graphisoft ArchiCAD gbXML • Autodesk Revit Architecture 2008, 2009, 2010, 2011 • Autodesk Revit MEP 2008, 2009, 2010, 2011 • ArchiCAD via gbXML • Microstation, Allplan via gbMXL • Google Sketchup 6 & 7 • Google Sketchup Pro 6 & 7 • The benefits…. • …don’t have to rebuild geometry to run analysis • …the potential to change the dialog between architects and engineers Other gbXML

17. IES VE: Autodesk Revit Plug-in Updates gbXML • How it works: • Draw Geometry in Autodesk Revit • 2. From the Revit Toolbar: • Set Building Location • Define Building Parameters: • Building Type • Construction Materials • Building System Types • Room Types • 3. Launch IES VE-Toolkits/VE-Pro • 4. Choose Analysis Type <VE>

18. gbXML Hierarchy

19. Adjacencies Adjacencies We spoke about the importance of ‘rooms’. Within Revit, you can define a wall to be an exterior wall, but this will mean nothing when it comes to the gbXML translation. The only way a wall is recognized as an exterior vs an interior wall is by their adjacencies. So for an element to be defined as ground floor slab, it is a horizontal surface adjacent to a room (otherwise it is a shading device) that is not in contact with any room below. For a floor, it’s a horizontal surface that is in contact with a room above and below. For a roof, it’s a horizontal surface that is not in contact with any room above. Exterior walls are vertical surface that is not in contact with an adjacent room on one side

20. Adjacencies

21. Keep It Simple Keep your geometry as simple as possible! • Is this geometry absolutely necessary for the type of analysis I am running? • Can I eliminate anything from my model? (Purge unused, etc) • There are often thousands of shading surfaces in a Revit file. If you are doing a daylight analysis, are the 4 cm mullions going to affect the outcome? They will affect the runtime significantly.
