8.6 Building Control Systems for Energy Efficiency

In energy and environmental management of a building, the human factor is a key element. Among the measures that contribute to promote a better management of the resources, there are actions that increase the awareness of the users who should be trained in how to use energy and avoid its wastage.

The involvement of people does, however, rely on a sense of individual responsibility and therefore the results that can be achieved are subjective. A strategy of this type is interesting and convenient because good results can be obtained with virtually zero costs. However the users, even if highly motivated, can but rely on their own sensory capacities, skills that not always lead an individual to act effectively.

A building control system (BCS) permits the management of energy resources with an objective approach, starting from certain information detected by appropriate devices, such as sensors for the detection of the temperature, carbon dioxide concentration, lighting levels or the presence of people.

A BCS has also the ability to process the information acquired by means of the sensors and to generate actions for regulation, control, optimisation and accounting. All this is done with maximum flexibility and total synergy between different systems. The added value that a building control system can provide compared to a standard regulation and control system is that all energy-using equipment and provision of services can be managed together.

A BCS is able to manage the following items [5]: delivering energy efficiency (through scheduling, unloading, and fault detection, controls have the capability of reducing building energy usage);
