NOW I AM REVIEWING, RE-CHECKING, AND WORKING MY " LARGE" TERRITORIES SINCE MORE THAN 55 YEARS AGO, SINCE I WAS TEEN.
THANKS.
HERE IS MY WORDS OF MY CONCERNS WITH MY BASIC FIELDS.
OK, VERY GOOD, VERY COOL AND WITH HOTTER WEATHER LATELY.

(3)
Stage lighting and other special lighting: Base on
dimmer capacity. Consider diversifying with house lighting.
b.
Power:
(1)
HVAC equipment:
generally 90% of connected load based on nameplate HP, but excluding
stand-by equipment, and non-concurrent loads.
(2)
Plumbing equipment: Same as HVAC but also
excluding fire pumps.
(3)
Elevator motors:
50% of the HP rating on nameplate.
