I am using an old 62MZ calculator file to do comply with the IEQp1 prerequisite. However, after adjusting the ventilation rates for peak heating mode, Ev cannot be calculated on the spreadsheet. I noticed that Ev is calculated using Appendix A, is there a way to switch the method from Appendix A to Table 6-3 to calculate Ev the same way as in the newer v4 Minimum IAQ Performance Calculator?

Try going to the credit resources tab and downloading the newest version. I believe the latest version can be used for ASHRAE 62.1 2007 or 2010.
