Overview

In order to start a new project, the user must first prepare basic input into a model that describes their building project. This model is called the UserModel . During the analysis calculation procedure, this model is used to automatically define the two compliance models:

1.    The Proposed Design Model— the Proposed Design model is very similar to the User Model; however, some inputs such as schedules, plug-loads, and others are replaced with prescribed values specified in the NACM.

2.                       The Standard (Baseline) Design Model— the Standard Design model is generated according the Standard Design rules in the NACM. Users can think of this model as a hypothetical version of their building if it was designed to just meet the mandatory and prescriptive requirements of the Title 24 (Part 6) standards.

The workflow for preparing the User Model and performing compliance analysis is broken into several steps. While all data input, and the analysis procedure, can take place directly in the IES VE user interface, Trimble SketchUp can be used as an alternative way to prepare the geometry.

The workflow is illustrated in Figure 8. Additional details for each step in the workflow are also provided below.

A building’s geometry can be imported via the IES VE module “ModelIT”, via SketchUp using the IESVE Plug-in for Trimble SketchUp, or via Revit using the IESVE Revit Plug-in.

For instructions how to use ModelIT module, please refer to the ModelIT User Guide available in the IESVE Support User Guide section of the IESVE website found HERE .

The Title 24 module can be selected from within the applications navigator on the left hand side of the Virtual Environment, in the Compliance and Settings section.

At the top of the workspace there is the Title24 toolbar, as seen in Figure 11.

Table 1 lists the description of each icon in the toolbar. The grey coloured items are not pertinent to Title 24 modelling.

The main menu can be found at the bottom of the Title24 module workspace, where the Title 24 Analysis tools and Results can be accessed. Figure below shows a screenshot of the main Title 24 menu, when a thermal zone is selected in the workspace.
