Smart ways for hotels to cut energy costs?

Sensors can be used to detect guests’ movements

There are “smart ways” to control a hotel’s energy costs, writes Mark Sait, founder of SaveMoneyCutCarbon, consultants for businesses and households that want to save money on utility bills and reduce their impact on the planet.

Any business in the hospitality sector will want to cut energy costs, “driven by three factors – energy prices, requirements to cut CO2 emissions and improving market valuation through a better bottom line,” he says – despite recent falls in oil prices.

“One prime candidate for energy efficiency in the sector is […] the guest rooms. We know that hotel guests spend very little time inside their rooms. In fact, our extensive research […] shows that hotel guest rooms are often empty for up to 46% of any 24-hour guest stay.”

Sensors can be used to show guests’ location, such as an entry-door monitor and one or more occupancy sensors, Sait suggests. These “smart guest room controls” can include infrared body-heat sensors and “an intelligent algorithm” to detect whether guests are in their rooms. Such a mix of sensors should not risk guests’ comfort while they are sleeping.

The controls should be able to easily check whether the guest is in-room and, if not, can switch that room to a money-saving, energy-saving mode after a suitable period – usually 30 minutes.”
