CI-2009 IEQp1: Minimum IAQ Performance
Hello,
We have a project that consists of renovating 3 separate spaces in a large commercial building. The building was designed under ASHRAE 62.1-1999 (applicable standard at the time) and received a LEED silver rating.
When complying with IEQp1 we understand that the ventilation systems serving the spaces to be renovated must comply with ASHRAE 62.1-2007. Is it also required to provide new ventilation air calculations under 62.1-2007 for rest of building as well?

Is outdoor air quality testing required in a space using natural ventilation?
What options are available to projects outside the US to meet this prerequisite?
Can LEED 2009 projects elect to follow ASHRAE 62.1-2010 for this prerequisite?
Which units should be included in the calculations for this prerequisite?

Matt, ASHRAE 62.1-2007 compliance is only required for the spaces within the proposed LEED-CI scope. That said, any adjustments made, could impact other spaces in the building, especially if you have multi-zone VAV systems.
