Can OpenStudio do LEED ASHRAE Standard 55 calcs?

asked 2016-01-18 19:03:33 -0500

updated 2020-01-27 18:44:17 -0500

Is it possible to get from OpenStudio a report to attend the verification of Thermal Comfort in the LEED IEQ Credit 7.1?

According to request in the LEED Online, it would be necessary the report incorporate, at a minimum:

  • space type
  • activity level
  • design operative temperature (heating/cooling)
  • design humidity range (heating/cooling)
  • and design air speed.

Yes. OpenStudio Measures are very flexible. The "Standard Report" measure is intended as an example that can be customized. You'll find a number of examples here, but this is probably an example closest to what you're looking for. Take a look at the Ruby code along with the online documentation for OpenStudio, and you should be able to flesh out a report that meets your specific needs. Reporting measures have been used for everything from model quality assurance checking to creating interactive psychrometric charts to interactive 3D visualizations of the envelope.

Dear Brackney,

Thank you for clarification.

Unfortunately I could not improve myself in the development of Measures.

But I thought that the EnergyPlus already had a default report for this proof as to have proof of compliance with the rule 62.1. As it seems that is not the case, I will try to develop a spreadsheet with the indicated mesures.

Thank you again!

The default EnergyPlus report is available in OpenStudio. Near the top of the results tab there's an option to select between the default OpenStudio report and the standard Energy Plus report you may be familiar with. If you drop additional reporting measures in your workflow, those will show up in that list as well. I would encourage you to at least take a look at some of the example reporting measures - you may be surprised at how easy they are to understand and modify!

@ljbrackney: May i get an measure example of creating interactive psychrometric charts. It's very interesting for me. But i have different view for measure development : if you did programming before especially in C++ or Ruby, OS measure is Swiss-knife otherwise for amateur developer/ simulation practitioner - it takes a lot of time for learning curve due to not so comprehensive SDK documentation and syntax structuring without standardized code instruction - many time i see both C++ and Ruby style code in measure example. many pathways makes newcomers confusing
