Pablo, good for you for taking actual measurements of your refrigerant values. Please go ahead and use the actual values in your LEED documentation. The table provided on P. 220 of the Reference Guide is simply a design tool to help inexperienced users verify that their refrigerant data is falling within the traditionally accepted ranges. However, actual values should always be used for refrigerant calculations in order to accurately document the conditions at your project building.

We have refrigerant re-charge data for most equipment. However, there are a few new equipment, as well as old refrigerators. My queries: 1) For the former (new A/C's), we have not yet recharged refrigerants. For the latter (old refs), we have not charged over time. Are we allowed to make assumptions for these? 2) Which assumptions are we allowed to make? - from the LEED EBOM manuals?
