Methodology Calculation
The Commission Delegated Regulation (EU) 2020/2155 established the definition of the SRI and a common methodology by which it is to be calculated. Its annexes provide general principles about (among other things): the calculation of smart readiness scores, the weighting of impact criteria in key functionalities, the weighting of technical domains and the smart readiness rating. The contents of these annexes form the SRI legal framework.
The SRI technical framework consists in a catalogue of smart-ready services (including mandatory and optional services) functionality levels and weighting factors. A generic, EU-level technical framework has been developed based on the outcomes of a technical study on the SRI carried out in 2019-2020 (see chapter 1 of the Final report on the technical support to the development of a smart readiness indicator for buildings). It can be provided upon request by filling this form (calculation sheet and practical guide). This video provides a live demonstration of using the calculation sheet of the generic, EU-level technical framework with practical examples.
EU countries, when testing or implementing the SRI, may adapt the generic, EU-level technical framework in order to take into account their national specificities.
