yes occupancy sensors are the best option and  best energy savers as well utilizing other factors for saving fuel water etc

Add sensors at the water taps ( out lets) which uses less water & reduces unnecessory wastage of water thereby saving in water & power also.

I appreciate your points Mr. Praveen, the points you gave really are efficient enough to make energy efficient hotels....

Excellent ideas.Putting Solar cells in the roof and outside the sun facing walls.Perfect sealing of rooms and make them air tight.If refrigerators provided should be placed in antirooms to reduce heat load in main room.LED lights for low wattage in passages and corridors.Only task light in dressing mirror and Reading table as well as in the bed head side with close switches,

If it is centralised AC Hotel properb isolating facility in every room should be available so that it can be immidiately operated when the room will be vacated.AC control temp can be raised to 24 celicious to reduce electrical load on AC.AC ducts shall be properly insulated.Windows glass panes shall be polarised and provided with full cartain to reduce heat entry throhgh window.

Any partition between AC and non AC area shall be with double door if posible furnished with Air curtain.

Providing auto closing in Bathroom door to avoid extra heat load .

Kitchen shall be well ventilated and away from AC area to avoid heat load.

Room service food shall be discouraged by differantial price as it increases heat load.
