First of all, (EN) ISO 52000-1, the overarching EPB standard, introduces the term “building portfolio”: a set of buildings and common technical building systems whose energy performance is determined taking into account their mutual interactions. An example of common technical systems is an energy generation system (PV panels, wind turbine, cogeneration unit, boiler, etc.) serving the building portfolio. So the interaction of a group of ‘nearby’ buildings is covered in the set of EPB standards.
Apart from that, the current EPB standards do not cover explicitly how to deal with a group of buildings. However, the interaction with the external world, such as electricity grid interaction (delivered and exported energy) should provide the information needed to assess a group of building i.e. a local network, See short video: on how to deal with exported energy to the grid.
Also in the current discussion, in Europe, of the Smart Readiness Indicator (SRI) it will be an issue that is expected to be addressed, in the coming months and years. Although this further depends on the acceptance of the SRI as a tool to show the potential level of interactivity between ‘your’ specific building and the energy grid. A bidirectional EV charging unit could be part of this local grid approach. The ongoing (2021) revision process of the EPBD may influence this process.
