Suqi Peng on 06 Feb 12Typically, the guest room energy costs will take up 40% to 80% of total energy costs of a hotel property, which depend on hotel size, location, and occupancy. There are 80% guest room costs related to the air conditioning and heating (HAVC). Another 20% of guest room energy costs are tied to electrical. Hotel HVAC systems are designed to maintain a guestroom at a fixed temperature both day and night. In many hotels - whether the guests are business or leisure travelers - the rooms are frequently unoccupied for much of the day. During those times, it will save hotels money to setback the thermostat or completely turn off the heating and cooling. Occupancy control system accomplishes just that. There are two major occupancy control system: cardkey system and occupancy sensor system. The primary benefit of occupancy control systems is that they reduce energy use for the hotel. Orchard Garden hotel installed the cardkey system to control their HVAC system and lights in guest room. According to calculate, there are average 26% reduction in HAVC energy costs. A second benefit is that occupancy controls reduce peak demand. However, both of cardkey system and occupancy sensor system have some weakness. They still need to enhance their technology and design to fix the problems
