How hotels with split air conditioning reduce energy costs
For many hotels, air conditioning is one of the largest and least controllable operating expenses. This is especially true for properties using split air conditioning systems, where each room operates independently and central control is limited or nonexistent.
Why controlling air conditioner runtime works better than sensors or apps
When property owners and operators first try to reduce air conditioning costs, their instinct is usually the same: detect behaviour and react to it. If nobody is in the room, turn the AC off. If a window is open, shut cooling down. If a guest leaves, intervene automatically.
