Air-conditioners consume the most amount of power in most residential and commercial buildings. The higher the building temperature, the more power consumed, and since most of our structures are ovens, (see roofing systems), we are paying too much to cool our structures.
So take all the advise under ‘roofing system’. Make sure your AC is not in direct sunlight, shading is recommended.
We have also seen advances in Air-conditioners, moving from piston to rotary compressors that used less power.
Level 1: Switch off all ACs when not in a room
Level 2: Get more fans and use less AC
Level 4: Add Infrared switches to AC and set them to switch off if no one is in the room for 3 or 5 mins
Level 6: Change or buy more energy efficient AC’s
