How do I resolve Unmet Load Hours?
The BPRM report shows too many unmet load hours. Why is this? How do I fix them?
See the Unmet Load Hour Troubleshooting Guide.
This guide is designed to help reduce or eliminate unmet load hours in a model. You should begin by understanding what an unmet load hour is, using the “Definition” section of this document. Next, you should identify when and where unmet load hours occur in your model. The “Unmet Load Hours Tests” section in this document will walk you through that process.
To determine the cause of unmet load hours in your model, follow the methodology in the “Common Causes of Unmet Load Hours” section. You can effectively interrogate the results of your building simulation by working through each subsection, or you may use the links in the Contents below to skip to a particular section for reference.
As you troubleshoot your model, you may find it useful to adjust the parameters of your dynamic simulation. The “Simulation Settings” section of this document will guide you through adjustments that may make your results easier to interrogate.
