What is the COMNET Portal?  The COMNET Portal is an online platform used to collect energy modeling simulation results, perform quality assurance checks, and submit the results to a rating authority.  The initial implementation of the Portal is designed specifically to submit the results to LEED Online for EA Prerequisite 2, and EA Credit 1 using the LEED Automation process.  In the future, we plan to expand this functionality to allow modelers to submit their models for code compliance, asset rating programs, and utility incentive programs.

How do I use the Portal?  It's simple!  With a few button clicks, your energy model results are sent directly to LEED Online.  Compare that with the current process and you will see the clear productivity benefit.  Previously, a modeler would be required to sift through pages of output reports, locate the appropriate data, post-process the results in a spreadsheet to convert units, and then manually type this information into the LEED Letter Templates. Now, with the COMNET Portal, a user simply imports the results to the Portal directly from the simulation software, the Portal filters the results automatically, performs QA checks to ensure the results are valid, and sends them directly to LEED online.  From the Portal, you can even review the official LEED Letter Template to ensure that it has been filled out appropriately.

What file formats are compatible?
In its initial release, the COMNET Portal offers two data paths for submission: file parsing for legacy outputs from eQUEST and the new COMNET XML Standard Output for other simulation tools. Currently, Trane TRACE™ 700 and EnergySoft's EnergyPro are configured to provide a COMNET XML ouput file. For eQUEST, the user simply uploads SIM files. The portal parses the files and extracts the data required for LEED submission.  Details for working with both submission paths are described in the tutorial.

What is the COMNET XML Output Standard?
Chapter 4 of the COMNET Modeling Guidelines and Procedures (MGP) specifies that the electronic format of COMNET standard reports will be XML. XML is a broadly used mechanism for describing, storing, and exchanging data. The primary function of XML is to effectively organize data and allow for it to be distributed in a platform-independent format. COMNET’s use of XML enables consistency as well as flexibility in the reporting process. Thus the XML schema for COMNET Standard Output facilitates straightforward data transfer from users to rating authorities. This standard is publicly available for vendors to incorporate in their building energy simulator software.


"The new COMNET portal gives software users a streamlined solution to completing LEED templates that will increase productivity and reduce the mistakes that are prone to happen when filling the templates by hand. Having completed several hundred templates by hand, our firm sees immense value in this new approach."

"The COMNET portal will allow design teams to spend more time focusing on optimization of proposed designs, rather than non value-adding tasks. I envision at least a day’s worth of time saved from not having to manually fill out forms for EAp2 and EAc1. The eventual automation of baseline model generation will result in substantial time savings, particularly for more complex projects. These savings can be passed on to the team to fund additional energy conservation measures or further focused building physics analysis."
