The potential of building automation for efficiency improvements in the building sector is only addressed to a limited extent by current policy instruments. The efficient, but also the grid-serving and user-oriented operation of buildings, which is necessary for the transformation of buildings from consumers to prosumers, is particularly affected. The EU Commission therefore introduced the concept of a Smart Readiness Indicator (SRI) when revising the European Energy Performance of Buildings Directive (EPBD) in 2018. The SRI is intended to show the capabilities of a building in terms of energy efficiency, grid serviceability and user serviceability. At the same time, it is intended to provide improved transparency on relevant measures to improve the above-mentioned capabilities of the building.
To this end, the EU Commission has designed an SRI methodology which, based on an inventory of existing smart-ready services, examines the building. These services are enabled by a combination of smart-ready technologies and are defined in a technology-neutral way. The functions of these "smart-ready services" are evaluated and, derived from this, the energy efficiency, network and user utility of the building are determined. Within the scope of this project, this proposed methodology of the EU Commission was to be examined and adapted to the conditions in Germany. The aim was to identify the optimisation possibilities of the instrument and to investigate which positive effect an application-friendly SRI can have on the energy efficiency and carbon footprint of buildings. The basic hypothesis here should be that SRI is not (initially) mandatory, but voluntary.
