NC-v4 EQp1: Minimum indoor air quality performance
posted by Francesco Passerini on Oct 9, 2017, 9:36 am

We are dealing with an educational building and we are considering ASHRAE 62.1-2010. Inside there is an infirmary.

Which occupancy category shall I consider for that space?

Marcus Sheffer LEED Fellow 7group / Energy Opportunities LEEDuser Expert 5547 thumbs up June 30, 2017- 9:57 am This is probably not the best place to ask software specific questions about how to model something. You can try BLDG-SIM at onebuilding.org or some of the other discussion forums or the Energy Plus help desk. If the software can't model your system directly then you would need to employ a work around. If you do so for LEED you must follow the exceptional calculation method and ideally base your work around on something that has been published. Often manufacturers of equipment...
