Hope this wasn't covered somewhere else on the forum.
Maybe someone here could eleviate my cofussion...
The current California Mechanical Code and Energy Code uses two different methods of calculating minimum ventilation requirements. The mechanical code uses ASHRAE 62.1, while the energy code uses section 121 (California Energy Commission).
When can the ASHRAE method be used, and when is the CEC method required?
I typically implement Demand Control Ventilation (DCV), and in most cases ASHRAE 62.1 works to my advantage (lower low limit ventilation requirement).
Also, if the ASHRAE 62.1 method can be used (building and occupant components), how do you show compliance using EnergyPro's Title 24 software?
I hope I'm not the only one confused by this.
Thanks in advance!
