Does anyone remember using or seeing a dwelling unit load calculator that may have been on the NFPA site?

I think I was linked to it on my introductory post ,last post at the bottom but that link is no good anymore. That may or may not have been the calculator I remember.

It was laid out almost in questionnaire format, walking you through the different areas on small pages with a “next” or “continue” button, and then gave a report in notepad. It was very simple, yet covered everything. It may have been a download or purchase type and I only had the trial. I’d love to find it again. It may not have been NFPA, I don’t know.

I've seen Mike Holt's excel spreadsheet. It's nice, but the locked cells make it hard to custom tailor it to an existing dwelling.

Any ideas or leads?

Bug in Online Dwelling Unit Calculator at electricalknowledge.com
I went to the electricalknowledge.com "single family dwelling Calculator" and tried it with the NEC Annex D example D1(A) and found it has an error in it. The name alone should tell a person an amateur wrote the program. It should be dwelling UNIT calculator. Anyway, for the 70 per cent calculation for the range neutral load they use 12 KW instead of the demand load of 8 KW. You would think that these people would at least try the examples to debug their programs. This tells me that they aren't good code people, but probably are programmers trying to do code programs.
Merry Christmas!
