SRI class

Class 65–80 %: smart

In short

1This page covers the "Smart" class of the Smart Readiness Indicator, with a score between 65 and 80 percent.
2Buildings in this class control major systems by zone and based on occupancy, and report faults automatically.
3What remains absent is flexibility toward the electricity grid, a capability achieved only in higher classes.

What does the "Smart" class mean?

The "Smart" class is one of seven classes of the Smart Readiness Indicator (SRI). This indicator measures how well a building is prepared for smart technology. A score between 65 and 80 percent falls into this class, with letter C in most tools.

The name "Smart" is not an official EPBD term, but a designation used by this platform. Official documents refer only to the percentage and the letter.

What can a building in this class do?

Major systems, such as heating, cooling and lighting, are controlled by zone. This means the entire building is not operated at once, but individual spaces are controlled separately.

The control also takes occupancy into account. Sensors or schedules ensure that systems adapt to whether people are present in a space.

Additionally, these buildings report faults automatically. A building management system (BMS) or building automation and control system (BACS) signals deviations, allowing managers to respond faster.

What is still missing?

Buildings in this class typically lack a function for flexibility toward the electricity grid. This means the building does not actively adjust its energy consumption based on supply and demand on the grid.

This functionality often requires connections with energy storage, electric vehicles or dynamic energy tariffs. These are features that emerge only in the higher classes of the SRI.

Why is this class relevant?

Many existing non-residential buildings with modern technical systems fall into this middle class. They meet a basic level of automation, without the most advanced features.

For owners of buildings with heating, ventilation or air conditioning capacity above 290 kilowatts, this is a relevant benchmark. The European Commission must adopt a delegated act by 30 June 2027 that is expected to make the SRI mandatory for this category.

What this means for you

Owner: If your building already controls by zone and occupancy and reports faults automatically, you are close to the "Smart" class. Consider expanding toward grid flexibility, so you are also prepared for stricter requirements that may follow after 2027 for larger systems.
Tenant: In a building of this class, you will notice that heating, cooling and lighting adjust to the space you occupy and whether you are present. Faults are often resolved faster, because the system reports them automatically to the manager.
Advisor: When assessing, verify that zone and occupancy control actually applies to the major domains, not just lighting. Also note the absence of grid flexibility functions, as this is often the difference between this class and the one above.
