Municipal and public buildings: what the SRI measures

What is the Smart Readiness Indicator for municipal properties?

The Smart Readiness Indicator (SRI) is a European measurement method that shows how well a building handles smart technology. The method looks at nine domains, such as heating, ventilation and lighting, and assesses the functionality level of systems present in each domain.

For municipal and public sector properties this is relevant because municipalities often have a leading role and must report on the energy performance of their buildings. A score based on the SRI methodology makes that reporting concrete and comparable between buildings.

Why does each domain not count equally?

The SRI assigns weighting factors per domain, based on their importance for energy performance and comfort. For municipal and public sector properties, heating, ventilation, lighting and monitoring and control carry the greatest weight, each with factor 3.

This fits the use of these buildings: a library or theatre has varying occupancy levels and therefore benefits greatly from smart control of ventilation and lighting. Monitoring and control, the building management system (BMS) that operates installations centrally, supports this process.

Why is a portfolio approach logical?

Municipalities typically manage multiple building types at once, from town halls to community centres. Operating hours vary widely, from office hours to evening use by community groups.

By applying the SRI across the entire portfolio rather than per building, you gain insight into where investments in building automation will have the most impact. This also aligns with often available funding opportunities for improving public properties.

When does the SRI become relevant for these buildings?

The SRI is currently voluntary. The European Commission must adopt a delegated act by 30 June 2027 that is expected to make the SRI mandatory for non-residential buildings with installations above 290 kilowatts.

Some municipal buildings, such as larger theatres or combined community centres, may fall above this threshold. Ahead of a requirement, an SRI assessment can now help map the portfolio in a structured way.
