SRI technical support studies

The potential of smart technologies in the building sector was heavily emphasised in the 2018 revision of the European Energy Performance of Buildings Directive (EPBD) and the concept of a Smart Readiness Indicator (SRI) was introduced. This indicator allows for rating the smart readiness of buildings, i.e. the capability of buildings (or building units) to adapt their operation to the needs of the occupant, also optimizing energy efficiency and overall performance, and to adapt their operation in reaction to signals from the grid (energy flexibility). The smart readiness indicator will raise awareness amongst building owners and occupants of the value behind building automation and electronic monitoring of technical building systems and should give confidence to occupants about the actual savings of those new enhanced functionalities.

Two technical support studies were tendered by the Europeasn Commision services. A first technical study to support the establishment of the SRI was executed by VITO, WSE, Ecofys and Offis. This project concluded in August 2018 and aimed at investigating the possible scope and characteristics of such an indicator. In June 2020, a second technical support study was concluded by the team of VITO and WSEE, which delivered the technical inputs needed to refine and finalize the definition of the SRI and the associated calculation methodology. At the same time, this study explored possible options for the implementation of the SRI and evaluated their impact on EU level in order for the Commission services to assess the technical modalities of an effective implementation of the SRI scheme.

The smart readiness indicator was officially adopted by Delegated Regulation and Implementing Regulation. The SRI is an optional common EU scheme; EU Member States may decide to implement the SRI on (part of) their territory, for all buildings or only for certain categories of buildings. 

The European Commission is providing support and guidance to EU countries and regions that implement or undertake a test phase of the SRI. More information and contact details of this support initiative are available on the Commission's website:
