FAQs about IEQp1 :

Is outdoor air quality testing required in a space using natural ventilation?

For a space designed to be naturally ventilated, can operable windows or vents be used to satisfy the 62.1-2007 requirements?

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?

My project is in design mid-review period, the reviewer gave a comment on IEQp1 which could be simplied as: “The total project area that is provided outdoor air is 10000 square meters (7000m2 for Phase I and 3000m2 for Phase 2); however, the ventilation calculations provided in the form indicate a total area of only 7000m2. Please provide a supplemental narrative and/or revised ventilation calculations to verify that all occupiable spaces have been considered to meet the requirements of ASHRAE Standard 62.1-2007.” The 3000m2 is part of building and reserved for phase 2 of project, this area is estimated by project owner and there is no detail design on this part, what should I do for the credit compliance? Do I need a project owner’s letter for clarifying these areas would be designed according to ASHRAE Standard 62.1-2007 in phase 2 ??

Make sure that the alternate space which is not being built is outside of your LEED boundary. If it is make reference to the boundary. If the area is not outside of the boundary then just highlight one of the sheets tat shows it as an alternate or future space and add a narrative about the fact that it is not going to be built. Either one of these methods should suffice.

Thank you Andrew, the areas should be accounted as "incomplete space" through LI#10102, I'm following the indications in that ruling, think it works.

Make the space between and, which is not outside the limits of your LEED requirements. This should be referred. If it is not the area outside the border, choose one or another of Cicero shows such a feel good story about the next, that they do not add in building. Of these, one was enough.
