ASHRAE 170-2008 Addendum m PDF

This addendum clarifies the requirements in Section 6.7.1 for the use of fully ducted return systems by recognizing that some spaces requiring a negative pressure relationship with the adjacent space require a fully ducted exhaust system rather than a return air system. This addendum also adds four spaces to meet the requirement for being fully ducted.
