Hi, according to ID#100000426 MADE ON 07/19/2010, the wording changed from: "In mechanically ventilated buildings, install new air filtration media in regularly occupied areas prior to occupancy...." To: "In mechanically ventilated buildings, each ventilation system that supplies outdoor air shall comply with the following" So, the wording does not include regularly occupied any more... Does this mean that filtration media is also required for ventilation systems supplying non-regularly occupied areas? e.g. a plant room?

The IEQ Space Matrix currently says that all spaces are required to comply with IEQc5. See this page for more info http://www.leeduser.com/blogs/leed-ieq-space-matrix-frequently-asked-questions

The October 2013 revision to the IEQ Space Matrix now states "Filter requirements are not applicable to nonoccupied spaces."
