Electric vehicle charging

What does the Smart Readiness Indicator measure for charging?

The electric vehicle charging domain examines the infrastructure for charging cars at a building. The Smart Readiness Indicator (SRI) is a European measurement tool that shows how well a building uses smart technology. Three smart-ready services are relevant for this domain.

Each service has functionality levels from 0 to 4. A higher level means more intelligent functions, such as management based on network capacity or automatic driver recognition.

Which three services belong to this domain?

The first service, EV-15, measures charging capacity. This concerns the percentage of parking spaces with a charging point, ranging from no charging points to more than half of all spaces.

The second service, EV-16, measures grid balancing. This addresses whether charging occurs unmanaged, or whether the system takes network signals and departure times into account. At the highest level, a vehicle can even return energy to the grid.

The third service, EV-17, covers information and connectivity. It measures whether users gain insight into charging status and whether the charging point automatically recognizes a driver according to the ISO 15118 standard.

Why does this count towards the score?

Each smart-ready service is assessed against seven impact criteria, such as energy efficiency and user convenience. These criteria, combined with weighting factors, determine how much a service contributes to the building's overall score.

For non-residential buildings with a heating, ventilation and air conditioning installation above 290 kW, building automation has been mandatory since the end of 2024. The SRI itself remains voluntary for now, though the European Commission is expected to change this for the same category of buildings by 2027 at the latest.
