Frequently asked questions on BACS systems and UNI EN ISO 52120‑1
The UNI EN ISO 52120-1 standard defines the efficiency levels of building automation systems. Class B requires advanced modulation of HVAC and lighting systems, while Class A represents high efficiency achieved through predictive optimization.
BRAINWATT® natively enables these classes by transforming technical assets into an intelligent system. Through the Optimization module, it introduces dynamic strategies based on weather data and occupancy to enable proactive consumption management.
To ensure compliance with Class A, a system must integrate load automation with forecasting algorithms. Criteria include continuous monitoring, automated orchestration of HVAC systems, and coordination with renewable energy generation.
The BRAINWATT® platform meets these requirements by integrating Monitoring, Anomaly Detection, and Optimization modules – technological components that are also essential to improve the building’s SRI (Smart Readiness Indicator).
The adoption of BACS technologies is incentivized by Conto Termico 3.0 to improve efficiency in the tertiary and public sectors and is also a key pillar of the EPBD4 Directive (Green Buildings) aimed at reducing carbon footprint.
The use of BRAINWATT® simplifies access to these incentives, as it enables existing systems to be classified under Class A or B efficiency levels. This ensures compliance with European requirements and guarantees operational continuity of building assets through modulated control.
A UNI EN ISO 52120-1 compliant BACS system acts as a centralized supervisor for all systems that influence energy performance. The scope includes thermal plants (heat pumps, AHUs), dimmable lighting systems, generation assets (photovoltaic, storage), and indoor environmental quality sensors (CO₂, humidity).
BRAINWATT® provides native integration of these vectors, ensuring that the entire building operates as a single optimized unit, maximizing occupant comfort and energy savings.
