This increases the probability that the planned measures for improving energy efficiency energy savings calculation is accurate and that the planned energy efficiency improvement measures in practice will give the expected results. 178. If a building planned to use similar to the above, the benefits of the planned energy efficiency measures for the evaluation of the use of certain climatic and population data. This allows you to assess the management practices of the buildings and the impact of changes in behaviour. 179. In identifying the necessary energy efficiency improvement measures, prepare one or more of the buildings energy efficiency scenarios in which specific and mutually agreed energy efficiency measures. Given that the individual events can interact (for example, increased thermal insulation or passive solar heat gains can lower boiler efficiency), each individual in the course of implementing the measures resulting effects may not be counted. The combined measures must be calculated taking into account the mutual interactions. 180. Each proposed scenario (includes specific energy efficiency improvement measures) the starting data changes according to the planned energy efficiency improvement measures and the calculation. The difference between the assessment, obtained before the energy efficiency improvement measures, and assessment, obtained by them, is the measure of the impact on energy consumption. 181. After the necessary identification of energy efficiency improvement measures for the calculation of a streamlined building regulatory energy efficiency assessment. For this purpose use the calculation model of the building with the issue (start) data set, taking into account the impact of energy efficiency improvement measures and regulations for the start of the data set. The energy efficiency improvement measures planned actual efficiency depends on how the building will actually be used. 182.
