Smart temperature control is crucial for the reputation of every hotel. Client’s satisfaction = success of your hotel business. You may have the best personnel, location or breakfasts but if guests are not comfortable in the room because it is too hot or too cold, you won’t get positive feedback from them.

So what needs to be done to ensure a comfortable indoor environment with the lowest energy consumption?

  1. Temperature setpoint in the room should be adjustable. Every person has its own comfort temperature level and thinking that 21C (69.8F)  will satisfy everyone may be a huge mistake. According to ISO7730 comfort zone also vary from 20C (68F) to 26C (78.F) depending on season as you can see on the graph below.

  1. Thermostat or wall panel should be easy to use. It should contain a maximum of four intuitive buttons. No one enjoys reading 50 pages manual about changing temperature setpoint for +1 deg. Intuitiveness is the key here. 
  2. Hotel room should be prepared for guest in advance. You know that feeling, when you just entered the room and survival instinct tells you to increase the temperature on a thermostat or you may freeze to death here? As a hotel owner, you should protect your client from that feeling. It takes some time before the air conditioning system will get the desired set point temperature. So if you want to make sure a guest is satisfied from the very first moment, you should have a hotel system which allows for adjusting the temperature setpoint according to the client’s schedule. Moreover, to achieve an ideal balance between energy savings and comfort, the hotel room should have three levels of temperature setpoints:

  1. Room setpoint should be adjusted according to outdoor weather conditions. It has been shown that a 1C (1.8F) decrease in indoor temperature may approximately cause a 10% reduction in heating costs and 5-10% of cooling costs. The facility maintenance team is a busy team, so they will not always be able to adjust the setpoint manually. Thus your BMS system should have a connection with weather service.
    1 C (1.8F) seems to be unnoticeable change, but it may impact monthly/yearly bill perceptible.
  2. In order to save energy, not occupied rooms should always be maintained at the level of minimum setpoint. The truth is that guests spend plenty of time outside of the hotel room and it is justified to use that information for extra savings. Motion sensors, occupancy buttons, cardholders are the solutions.
  3. An opened window should cause  turning off temperature control in the room. BMS system should protect you from wasting energy. We know that some guests want both -  open window with “fresh” air and effective room temperature control at the same time and our task is to prevent such controversial behaviour.
  4. Building Management System should regularly provide full, easy to read energy reports. Data will allow you to understand how effective you are managing your hotel. “What gets measured gets managed” Peter Drucker.
