Building Control Elements
Devices that form part of a control system that responds to sensors adjusting the internal conditions accordingly to match demand.
The internal environment refers to the strategy employed to heat, cool and distribute air around a building. The internal environment can be heated and/or cooled, whilst air distribution could be through natural or mechanical methods, or a mixture of the both for a mixed-mode strategy. If comfort cooling is provided throughout the internal environment would be fully air conditioned.
Building Management System (BMS)
A computer based system that provides varying degrees of functionality to control building services.
A form of control for heating systems that automatically regulates the internal temperature based upon weather conditions.
Controls that monitors levels of daylight to switch on/off or dim lighting to match the actual requirement.
A device that detects if people are within a particular area of a building.
Optimised Start (Optimiser)
A controller that adjusts the start (and stop) time of the heating system to ensure is comes on (and goes off) at the desired time to match the temperature of the building.
