The new USGBC-provided "Minimum IAQ Performance Calculator" appears to be applicable to LEED 2009 and LEED v4 projects in that it includes calculations for ASHRAE 62.1-2007 and 2010. However, the spreadsheet is "protected" and does not allow you to enter additional space types, such as those found in FGI or ASHRAE 170. So how are you supposed to use this spreadsheet for LEED for Healthcare projects?
