Areas with a metabolic rate outside of 1.0-1.3 need to use a different tool to show compliance with ASHRAE-55 for that space. For spaces with metabolic rates below 1.0, utilize a tool like this one from UC–Berkeley rather than following the graphical method. 

ASHRAE-55 was designed to accommodate activities up to 2.0 MET, but it’s possible to have higher MET levels in your project if you have a kitchen, fitness center, gymnasium, or warehouse. If this is the case, refer to LEED interpretation #10279 for guidance. 

Most spaces with MET levels above 2.0 need to meet the cooling and humidity temperature set points for spaces with MET levels of 2.0 in order to meet the intent of EQc7.1.

In order to demonstrate compliance, project teams need to complete one of the following options:

Option 1. Evaluate whether the activities in the space will be continuous or varied. For example, in a fitness center, occupants may be expected to spend about half the time working out and half the time resting or stretching. The best way to approach the calculation would be to use the time-weighted average metabolic rate over a typical hour. Appendix A of ASRHAE-55 explains time-averaging in detail.

Option 2. If the time-averaged metabolic rate is still above 2.0, then the engineer will not be able to use the graphical method. Use the PMV method of compliance, utilizing a tool like this one from UC–Berkeley with the appropriate Clo levels, but with MET set to 2.0.

Option 3. Identify some other source (such as industry group, specialized ASHRAE design guide, etc.) that is specifically about the area under question, identify the recommended temperature and humidity setpoints, and the document that the mechanical systems have been designed to maintain those setpoints.
