Temperature control of buildings can be inefficient due to heating/cooling an area when it is not in use. This article proposes a system to counter this energy waste by using existing calendar entries to determine room occupancy.

Determining environmental controls based upon calendar scheduling

Current environmental controls for most office spaces are set by programmable thermostats. These are often used to maintain a constant temperature at set times of the day but take little consideration of the actual usage of the space. This can often result in empty office spaces being heated or cooled while vacant, thus

wasting energy. To reduce waste, we aim to adjust the environment settings of an

office space based on a more precise prediction of when the space is in use. The current solutions for controlling the environmental settings include:

• Thermostats - set the environmental settings to be on or off based on a predetermined condition, usually room temperature or time.

• Programmable Thermostats - Allow the environmental settings to be set to different levels for different periods of the time. The advantage these have over Thermostat Controlled systems is they allow the climatic settings to be changed dependent on the time of day.

• Heating, Ventilation & Air-Conditioning (HVAC) Control Systems - computerised control system for the climate control in commercial buildings. These can be used to control the climate of individual areas of a building using a networked central controlled system. These systems do not have the draw backs the traditional thermostats have but still fail to take into account the actual usage of the room

    Electronic calendars could be used in conjunction with the above techniques to control the temperature of areas/rooms in a building depending on if that location is actually in use. Rather than manually inputting...
