In The main objectives of the VE-Gaia PRM (Performance Rating Method) Navigator are to:

1. Manage the overall process, including inputs, edits and cycles of the PRM (ASHRAE 90.1 Appendix G)

2. Provide industry recognized defaults and input selection options (ASHRAE standards data as the basis) to assist the process

 

A range of individual software modules and features are available within the VE-Pro suite which can be used to construct a detailed PRM model. The user needs to manually switch between modules and know at which point in the process a specific feature needs to be used. In summary it can be

difficult to understand how each module and feature fits into the overall PRM workflow analysis process.

The VE-Gaia PRM Navigator is a tool which brings all of the individual VE-Pro modules and features together in a single area and presents the user with step-by-step smart navigation and management of the PRM workflow and analysis process. The Navigator is driven through the successful execution of specific actions and commands which are activated by the user in a defined sequence. This smart navigation leads the user through the process of basic geometry creation, to constructions/thermal data assignment, and ultimately to the automatic generation of a full set of PRM compliant results which are presented in a format similar to the LEED EAc1 Letter Template.

 

The Navigator also provides the user with predefined prototypical ASHRAE data which can be used

to populate the model with default baseline information. The main structure of the PRM Navigator

workflow includes:

1. Preliminary Data setup

2. Envelope Thermo/Physical Properties

3. Room/Zone Thermal Template Data

4. HVAC systems

5. Other Input Data

6. Generate Baseline

7. Sizing runs

8. Simulations

9. Results

 

The ASHRAE 90.1 App – G PRM Navigator functions as a series of hyperlinks that are accessed within the smart navigator tree structure that is located on the upper left side of the interface. The hyperlinks take the user to the relevant VE-Pro module and dialog box to complete the tasks associated with that topic.
