NC-2009 EAp2:Minimum Energy Performance

EAp2 -3 Energy Type Summary

I need help on what numbers to use in this table. I keep getting an error message, too, that says: " If revising the values in Table EAp2-3, reselect energy type in all affected rows in Table EAp2-4 and Table EA[2-5 to ensure that the revised values . . . are propgated and refreshed. I went through those tables and reselected each energy source. I am still getting the error message. I have erased it all and put it all in new and I still get that error message! What am I doing wrong?

My Engineer is getting the same response. And everything is filled out? Anyone else have this issue/error message. No fields are red only the following text: If revising the values in Table EAp2-3, reselect energy type in all affected rows in Table EAp2-4 and Table EAp2-5 to ensure that the revised values from Table EAp2-3 are propogated and that Table EAp2-4 and Table EAp2-5 calculations are refreshed.

We are getting the same error. It's very frustrating. We have been told that it may just be a glitch in the version. We plan to go ahead and submit it with this error anyway. Please post if you are able to fix it. We spent a week or more trying to remedy this with no luck.

As long as Tables EAp2-4 and EAp2-5 are adding to the correct totals then ignore the warning. Make sure the totals in these tables match the summary output reports from the simulation results as the reviewer will check that if they see the error message.
