I am looking for a base template that can be edited for Volatile Organic Compounds (VOC) and Hazardous Air Pollutants (HAPS) for paint used on components for exterior building envelopes. I've been asked to create an Excel spreadsheet that will automate the calculations by someone who did not create the template and does not know why certain calculations are made. I am not familiar enough with this topic to be comfortable (or confident) in automating the calculations just because someone has "always done it this way" if I am to be held responsible for miscalculations. Is there anyone on here who is familiar with this and can assist?
