2.7 Ventilation Requirements

Design decisions regarding outside air ventilation shall be based on §120.1 of the Energy Code. If local codes do not apply, minimum values from Appendix 5.4A shall be used. Chapter 5.6 HVAC Zone Level Systems of the ACM has additional information on the ventilation requirements used in the building descriptors for the proposed and standard design. While no compliance credit can be claimed for reducing ventilation rates in the proposed design below the required levels, the user can specify higher ventilation rates in the proposed design.
