CI-2009 IEQp1: Minimum IAQ Performance
If a CI project is being built out in a building that is certified under Core and Shell to meet ASHRAE 62.1-2004, does this prerequisite require that all spaces within the scope of the TI meet 62..1-2007, even if the base building HVAC is outside the scope of the TI?

David,
The TI spaces need to meet 62.1-2007. A plus: the ventilation rates are the same for most space types between the 2004 and 2007 versions. You do have to be careful to show compliance with 2007 on a space by space basis within the TI area. Some designers run into problems when TI spaces have a high proportion of densely occupied areas (like conference rooms) and the CS HVAC system only accounted for an open plan office, for example.
