Analysis of Member States' rules for allocating heating, cooling and hot water costs in multi-apartment/purpose buildings supplied from collective systems

The Energy Efficiency Directive (EED) requires, subject to certain conditions, the introduction of individual metering and consumption based billing - also known as "sub-metering" - of heating, cooling and hot water in multi-apartment buildings with collective supply systems. Where meters or heat cost allocators are in place, there are different ways of using the measurements to allocate the costs to individual occupants. This report – prepared by the Commission's Joint Research Center for DG ENER- provides an overview of the existing thermal cost allocation rules in Member States, characterising them in terms of key features.
