Automation is a standard
Directive 2018/844 takes an important step in the direction of intelligent buildings, in continuity with many actions that the European Union adopted in recent years.
The directive amended the previous directives on the energy performance of buildings (2010/31/EU) and on energy efficiency (2012/27/EU), requiring that large non-residential buildings will be equipped with automation and control systems by 2025. The boundary to be considered as "large buildings" is, in this case, the effective rated power of air conditioning systems (or combined air conditioning and ventilation systems) which must exceed 290 kW.
In the directive, the attention of the European Parliament and the Council has been focused on the energy benefits that the use of building automation and control brings. In fact, the European Union is aiming for a sustainable energy system by 2050 with the aim of decarbonising the building stock, which accounts for about 36% of all CO2 emissions.
For this reason, automation and control systems must monitor, record and analyse the use of energy in buildings, allowing it to be adapted at all times. In order to reduce energy consumption, it is also recommended that efficiency losses be detected and that the person responsible for the building's facilities or management be timely informed.
Finally, the use of "open" systems is a key point. The systems are required to allow communication with installations and other equipment inside the building and to be interoperable with technologies, systems and devices of different manufacturers.
