Power Factor doesn't have a thing to do with the actual heat energy being dissipated by the load.
Previous response is confusing Power Factor with Efficiency and though they affect each other they are not the same.
The Watt -> BTU conversion is based on Real Power (Watts) and Time, not Apparent Power, so forget about VA and use Watts or Kilowatts and Hours.
Using Load Current of 28.14 Amps and Load Voltage of 208.2 VAC tells you the load is up to 5858.748 Watts.
Using the -Efficiency- data (Load Power) you know the Load is 72% of the Total Power input.
Total Power = 8137.15 Watts [Max] -> This is Load + APC Unit power use.
Load + APC Unit power is what you need to determine how much heat is being disipated by ALL the equipment. [Unless your APC is in an area cooled by some other AC unit.]
1 kWhr = 3412.14 BTU/hr ... so you have 27,765 BTU/hr going on.
[yes] 1 Ton = 12,000 BTU/hr ... so you have 2.31 Tons of cooling to do.
