1. Introduction The IES Toolbar Plug-in for Revit Architecture is a free Plug-in that provides a link between Revit Architecture and both the IES Sustainability Toolkits and the IES . The Plug-in provides an easy interface between Revit Architecture and the IES suite of tools that is close to that of the Revit MEP 2008 connection via a Toolbar with three buttons and a menu bar option.

1.1. How to Access the IES Toolbar? When the IES Toolbar plug-in has been properly installed you will see 3 buttons below the Revit Toolbars at the top of the Revit Architecture screen and an IES dropdown added to the menu bar.

These buttons allow data to be easily assigned to the model so that Sustainable Analysis using the Sustainability Toolkit or full can be performed at any stage in the design process.

1.2. IES Toolbar and Menu Options 1.2.1. Set Model Properties

This launches the Set Model properties dialog and exports a gbXML of the current Revit project. This gbXML will be saved in the same folder as the Revit project and will have a name of the form “’Revit project name’iesve.xml”. For changes to the Revit model to be updated in the gbXML then the Revit project must first be saved before Set Model properties. 1.2.2. Toolkit button

This launches the Toolkit for the current project. Note: This can only be used after Set Model Properties.

2. Working with the IES Toolbar Sustainability Analysis can be used at any stage of the Building design cycle and the earlier it is implemented the greater the benefits will be in the final design. No matter what stage of development the building is in the same basic steps are required to get realistic results for the building. First, Set Model Properties is used to pass the model to the and apply the basic data required for calculations. Then it is easy to either run fast Sustainable Analyses using the IES Sustainability Toolkit or to use the full suite to launch the with the model already prepared for calculations. The next section gives further instruction on how to apply data to the project and then how to use the Sustainability Toolkit.

2.1. Set Model Properties This is always the first step when using the IES Toolbar to perform calculations on a Revit Architecture model. When this button is pressed the current Revit model is exported as a gbXML and the Set Model Properties dialog is opened. It is not possible to launch the Toolkit or until this has been done and the gbXML model has been checked to confirm it imports to the without any problems. The Set Model Properties window allows the imported model to be viewed with the Modelviewer controls (for further information regarding the Modelviewer please see the ModelIT User Guide). Template data can be set to rooms or the building as desired.

2.1.1. Check Model Following the advice given in the Building performance Analysis Using Revit document (available by selecting Model Guidance from the IES menu) 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. 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 accuracy of 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 model. 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.

2.1.2. 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 the Sustainability Toolkit to get early Energy, Carbon and Daylighting assessments and compare different architectural design options.

Building Type is used to apply thermal template data including Heating and Cooling Set Points, Internal Gains and Air Exchanges. Simply define the main use of the building from the list which includes Office, Hotel and University/School amongst others. Building Constructions is used to apply constructions from the Constructions Database to surfaces and openings in the building. Click the Constructions Button to open the Building Construction dialog.

Page 8 of 22

The only Construction Type available to edit here is for the whole building. Simply choose a construction for each Surface and Opening in the model from the extensive lists and these are applied to each occurrence of that surface in the building. It is very important this is done as Construction data is not passed directly from the Revit model. Building Service can be used to select a System for the building by choosing an option from the list. No other input data is required here. Place and Location allows the building geographical position to be set. This defines the Weather and Climate data that is 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.

2.1.3. 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 of 22

Data is applied to each room similar to the way it was applied to the building in the Building Tab. The Level, Select and Isolate buttons make it easier to check the data is applied to the correct room. Level – Select a Storey from this dropdown to display only the rooms that have their base on that floor. Select button When the Select Button is pressed the Modelviewer will display the building as an x-ray with any selected rooms highlighted Red.

Isolate Button When the Isolate Button is pressed the Modelviewer only displays the rooms that are selected on the list. Room Type, Room Construction and Room Service can be used to apply data to the selected room(s). This will override the Building Type data applied for the selected rooms. Page 11 of 22

Room Type is used to apply thermal template data including Heating and Cooling Set Points, Internal Gains and Air Exchanges. Define the use of the room by selecting an option from the list. Select to make the Room Activity the same as is set for the Building. Room Constructions 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.

Note: this differs from Building Construction as multiple Construction Types can now be created and applied to different rooms.

New button - adds a new Construction Type with default constructions. Delete button – Deletes the currently selected Construction Type.

Duplicate button – 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 to use the same system as the Building.

2.2. Toolkit Further information regarding the Toolkit can be found in the Sustainability Toolkit User Guide. The Sustainability Toolkit allows users to quickly and easily perform ASHRAE and CIBSE Loads Calculations, ApacheSim: Dynamic Thermal Simulations and FlucsDL: Daylighting Assessments on their models. Also Sun’s View Movies can be created of models. Currently the LEED Toolkit is additionally included which allows a LEED Daylighting Credit 8.1 report to be produced.

2.2.1.6. Sun’s View Movie

Sun’s View creates videos from the view of the Sun as it passes through the sky. Select a month then press the button to create the video. Suncast generates a series of images of the model taken from the position of the Sun in the sky at each hour between sunrise and sunset on a default day in the selected month (the 21st). These are then used to create a video showing the model as the sun passes through the sky. 2.2.1.7. LEED Daylighting Credit 8.1 Report

FlucsDL analysis data is used to calculate the daylight illuminance level in each room of the model. The report details the floor area of each room and the area that receives a daylight illumination level of at least 25 footcandles. The building will Pass this credit if at least 75% of all regularly occupied areas receive this minimum threshold daylight illuminance level.

2.3. Settings

Settings should only be changed if you are experiencing any problems using the IES Toolbar.

If ‘Automatically Generate gbXML’ is unchecked the Set Model properties will not export and save a gbXML of the current project. In this case the user will have to manually export the gbXML and save it in the same folder as the Revit project with the naming convention “’Revit project name’iesve.xml” so that it can be used with the or toolkit. The Export, Save and Yes controls should not be changed without first consulting [email protected] These represent the keystrokes invoked to Export a gbXML and Save It, as is required to pass the Revit project to . If the keyboard shortcuts in Revit have changed, then the IES settings must be updated accordingly.
