SRI default calculation

Service catalogues ought to be defined by the Member States. As a result, different smart ready services per technical domain may be considered among European countries.
The definition of weighting factors of technical domains per impact criterion is the prerogative of Member States as well. The standard approach to define the weighting factors of certain technical domains (i.e., heating, domestic hot water, cooling, ventilation, lighting, and electricity) as the energy balance per climatic zones. The remaining technical domains’ weighting factors per impact criterion (i.e., dynamic building envelope, electric vehicle charging, and monitoring and control) are either fixed or equally distributed. For the calculation of the energy balance, energy performance in buildings assessments as per the energy performance certificates may be used. The climatic zones are defined by Member States, and it is possible to have diverse sets of weighting factors depending on the building type. Approaches for the weighting factors definition which deviate from the standard approach are also possible.
Member States shall also define the the weighting factors related to the influence of each key functionality in the total smart readiness score.
To avoid unfairly penalising a building or building unit, some smart-ready services may be omitted in the calculation of the smart readiness scores in case those services are not relevant for that building or building unit. Member States shall define the conditions for allowing such adaptations of the calculation procedure.
Member States may define additional considerations in terms of inclusiveness, connectivity, interoperability, cybersecurity, data protection, etc.
