As the energy consumption increases, the energy efficiency measures must be found and implemented. 2012/27/EU Energy efficiency Directive aims the targets to decrease energy consumption for a final energy consumer by 1,5 % annually, but do not defines how these targets can be achieved by member state. Article presents the analysis how these targets can be reached by the means of individual heat metering for every flat decreasing energy consumption for a final consumer. Statistical analysis of identical buildings with heat cost allocators and without them is presented. Heat cost allocator do not decrease energy consumption by itself, so this article presents a technical solution and a set of additional equipment as thermostatic valves, balance valves, hot water meters and remote system must be installed. The final results shows that the targets of 2012/27/EU Energy efficiency Directive can be reached as the buildings with individual heat cost allocators
consumes about 20-30 % less of heat energy.
