3 Introduction The provides a link between Autodesk Revit Architecture and MEP and IES VE-Ware, VE-Toolkits and VE-Pro. This plug-in provides an easy interface between Revit Architecture and MEP 2008/2009/2010 and the IES suite of tools to allow sustainable performance analysis. Access When the IES Revit plug-in is installed the IES Toolbar will appear under the Add-Ins tab of the Revit ribbon toolbar. Note: In versions of Revit prior to 2010 the IES Toolbar is accessed below the standard Revit toolbars and IES<VE> dropdown in the menu bar. Performance Analysis can be carried out at any stage of the Building design cycle and the earlier it is implemented the greater the benefits will be in the final design. When the model geometry is complete and room/space elements have been placed the model is ready to begin analysis. Click the Import Model button to transfer the model via gbxml to <VE>, then use the VE-Ware, VE-Toolkits or <Virtual Environment> buttons to perform different analyses as detailed below. User Settings and Information Settings and Info Opens the IESVE Revit plug-in About dialog. Here information for IES Technical Support can be found and settings such as Units and gbxml Export quality can be set. Settings Click the Settings button to edit units (Imperial or Metric) and to define quality of gbxml Export when model is exported from Revit to <VE>. page 3

4 Export Quality Settings: Export type Simple Simple With Shading Surfaces Complex Complex With Shading Surfaces Complex With Mullions And Shading Surfaces Brief explanation Simple means that Curtain Walls and Curtain Systems are exported with one complete opening with the total opening area equal to all openings combined; a curtain wall with 50 panels gets exported as 1 opening. Export with simple type and shading surfaces. Complex means that Curtain Walls and Curtain Systems are exported with several openings, panel by panel; a curtain wall with 50 panels gets exported as 50 openings. Export with complex type and shading surfaces. Export with complex type, shading surfaces and mullion. With Mullions mean that Mullions in Curtain Walls and Systems are exported as shading surfaces. A "simplified" analytical shading surface is produced from a mullion based on its centerline, thickness and offset. Override MEP transfer: This option is available in Revit MEP 2010 onwards, when ticked the Set Model Properties dialog is displayed when Import Model is clicked. When unticked the Revit Export gbxml dialog should be used to set model properties prior to any export and analysis using the IESVE toolbar. Help Opens the IESVE Revit plug-in User Guide. Guidance Opens the BIM + Building Performance Analysis Using Revit 2009 and IES <Virtual Environment> White paper, provides extra guidance on using the link between Autodesk Revit and IES <VE>. page 4

6 Set Model Properties Set Model Properties The first step when using the is to click the Import Model button to pass the model from Revit to <VE> via gbxml. When this process is complete the Set Model Properties dialog will open displaying the model in a <VE> ModelViewer. The Set Model Properties dialog allows the quality of geometry export to be checked and thermal data can be applied to the model before analysis begins. Note: In Revit MEP 2010 onwards model properties are set in the Revit Export gbxml dialog. Access this by clicking File >> Export >> gbxml. When the model is ready click the OK button to close the dialog. Click the Import Model button to generate the IES Model Check Report before proceeding to analysis. To use the IESVE Set Model Properties dialog instead please see Override MEP transfer in the Settings options (described above). Check Model Following the advice given in the BIM + Building Performance Analysis Using Revit 2009 and IES <Virtual Environment> white paper (available by clicking the Guidance button) the gbxml should be of a high quality but it is still very important to check the model has been properly exported before any analyses are performed. Click the Check Model button to generate the IES Model Room Check Report. This report gives information regarding the geometry of each room in the model with any values outside expected bounds highlighted. page 6

7 Set Model Properties Missing Surfaces shows rooms that may have gaps where surfaces do not join correctly. It is important these problems are identified and corrected as the missing area may allow light, solar radiation and air flow thermal transfer between zones. This would affect the calculation results. Ratios and areas of walls, floors etc should be compared to original designs to ensure all data has been correctly transferred to the <VE> model. Holes to Ceiling/Floor can highlight rooms that are not properly bounded by a floor or ceiling/roof. When the model data has been checked and confirmed then the IES Report can be closed and the check box can be ticked. It will not be possible to set Model Properties until this has been done. Building Data Early in the design process room layout and usage may not yet be known. Analysis can still be performed, however, by assigning more general data to the entire building on the Building tab of Set Model Properties. Simply by defining usage, constructions, an HVAC System and the location of the entire building it is possible to start using VE-Ware and the VE-Toolkits to get early Energy, Carbon and Daylighting assessments and compare different architectural design options. page 7

8 Set Model Properties Building Type Define the primary use of the building from the list which includes Office, Hotel and University/School amongst others. This is used to apply thermal template data including Heating and Cooling Set Points, Internal Gains and Infiltration rates. Building Constructions Apply constructions from the IESVE Constructions Database to surfaces and openings in the building. Click the Constructions button to open the Building Construction dialog. The only Construction Type available to edit here is for the whole building. Simply choose a construction for each surface and opening type in the model from the extensive lists. These constructions will then be applied to each occurrence of that surface in the building. Note: Construction data in the form of Revit Architecture or Revit MEP is not passed directly from the model. page 8

9 Set Model Properties Building Service This is used to select an HVAC System for the entire building. Building System Active Chilled Beam Central Heating Convectors Central Heating Hot Air Central Heating Radiant Floors Central Heating Radiators Constant Volume Dual Duct Constant Volume Fixed O A Constant Volume Terminal Reheat Constant Volume Variable O A Fan Coil System Multizone Hot Deck Cold Deck Other Room Heater Radiant Cooled Ceilings Radiant Heater Flued Radiant Heater Multiburner Radiant Heater No Flued Split Systems With Mechanical Ventilation Split Systems With Mechanical Ventilation With Cooling Split Systems With Natural Ventilation V A V Dual Duct V A V Indoor Packaged Cabinet V A V Single Duct Variable Refrigerant Flow Water Loop Heat Pump Mechanism Cooling only Place and Location Set the geographical location of the building. This defines the Weather, Climate data, Sun Path and light across the building that are used in Sustainability Calculations. Latitude and Longitude information about the current location can be viewed by clicking the Place and Location button. To change location click the Select button. This opens the Select Site Location dialog which shows the locations available in each Continent. Choose the location which is nearest to where the building will be constructed. page 9

10 Set Model Properties Room Data Later in the design stage, when more detailed information about the building is available, data can be applied to individual rooms to obtain more accurate analysis results. To enter Room Data click on the Rooms tab. page 10

11 Set Model Properties Level - Select rooms by storey i.e. ground floor, first floor, second floor. Select - When the Select Button is pressed the Modelviewer will display the building as an x-ray with any selected rooms highlighted Red. Isolate - When the Isolate Button is pressed the Modelviewer only displays the rooms that are selected on the list. Room Type, Room Construction and Room (HVAC) System can be used to apply data to the selected room(s). This will override the Building Type data applied for the selected rooms. Room Type Define the use of the room by selecting an option from the list. This is used to apply thermal template data including Heating and Cooling Set Points, Internal Gains and Air Exchanges. Select <Building> to make the Room Activity the same as is set for the Building. Note: Spaces whose room type is chosen as unoccupiable or plenum will NOT be considered habitable area therefore will not be part of the area calculations of the building for the Energy Use Intensity. Room Constructions This is used to apply constructions from the Constructions Database to surfaces and openings in the rooms. Click the Constructions Button to open the Room Construction dialog. page 11

12 Set Model Properties Note: this differs from Building Construction as multiple Construction Types can now be created and applied to different rooms. New - adds a new Construction Type with default constructions. Delete - Deletes the currently selected Construction Type. Duplicate - Copies the currently selected Construction Type. Building Service If any rooms use a different HVAC System from the one selected for the building this can be specified here. Select <Building> to use the same system as the Building. VE-Ware The VE-Ware button runs a dynamic thermal Apache simulation and generates whole-building annual energy and carbon usage results. A report is generated showing details of total Energy usage, Energy breakdown by usage, total Carbon Emissions and, depending on location, comparison against NZBC Clause H1 Compliance (New Zealand) or Architecture 2030 Challenge targets (rest of world). Further information is available from the IES VE-Ware User Guide and the IES website. page 12

13 VE-Toolkits VE-Toolkits The IES VE-Toolkits are a set of analyses that can be run to help influence and direct early stage building designs. These fast analyses can be run with basic model inputs to allow indicative assessment of design options taking into account climate, building fabric, energy & carbon, thermal loads, daylighting and solar shading. Further options offer an assessment of the potential for Low or Zero Carbon technologies and water reduction. Using the VE-Toolkits for LEED the building model can be appraised against LEED credits to give an indicative result based on credits that cover daylighting, comfort, water and Renewables. Click the Guidance see the IES website. button to open the VE-Toolkits User Guide for more detailed help and also Sustainability VE-Toolkit The Sustainability VE-Toolkit is divided over two tabs; Overview and Sustainability. The Overview tab can be used to give a greater understanding of the implications of the building location by understating climate and uses this information to offer guidance on building fabric design, materials and potential strategies for further investigation. The Sustainability tab allows early stage analysis of Energy and Carbon emissions, Heating and Cooling Loads, solar shading and daylight assessment and Water and Low or Zero Carbon Technologies reviews based on building design and simple inputs. page 13
