Sir if you have an AC, Ref, motors and/or other heating devices you may consider selling it and upgrade to newer and higher efficiency systems.
imho, in one of the buildings i manage, previously we have 20HP motor for an AHU but when we upgraded the blower wheel assembly with lighter material and newer design we reduced the consumption of this particular AC equipment into technically half, having a payback period of more or less a year.
this are mechanical intervention, wala pang electronic and electrical intervention,.
