When using the steady-state method, the total heat losses through transmission shall be calculated for each month or season and each zone by using the following formulas:. 003-01 dynamic effect shall be taken into consideration in calculations when introducing the gain utilisation factor for heating and the loss utilisation factor for cooling.
If in the previous time period accounting of energy carriers has not been carried out, lbm assessment of the measured energy performance of a building may not be performed. The set-point temperature Tuzst,dz. Consumption of liquid fuel in the assessment period shall be the contents of the tank at the beginning of the assessment period, from which the contents of the tank at the end of the assessment period have been deducted and to which the amount of the fuel purchased in the assessment period has been added.
A apr – calculation area m 2which shall be determined in accordance with Sub-chapter 5. If necessary, initial data shall be adjusted, in order for a comparison of the energy performance results to be acceptable. An energy rating, when determining annual energy consumption, shall include the technical building systems, which ensure:.

Part of unused heat causes the necessity for cooling, in order to avoid raising of the internal temperatures over the set-point temperature. Q dz,n,kopa,zs – total energy required for the cooling of all building zones zswhen using a combination of definite systems Wh.
Primary energy factors for the part of non-renewable energy resources are specified in Table 2 of this Annex. Rural Sustainability Research Former: Q apk,n,kopa,zs – total energy required for the heating of all building zones zswhen using a combination of definite systems Wh.
Thermal energy gains include internal heat gains and solar heat gains. Q apk,n,kopa,z – total energy 0003-01 for the heating of the building zone zwhen using a combination of definite systems Whwhich shall be determined in accordance with Paragraph of this Regulation.

Development of the typical meteorological database for Chinese locations. If an assessment period is not the full number of years, the annual energy consumption shall be obtained by using the extrapolation method.
F h – shading bln coefficient for the influence of the horizon in accordance with Table 1 of Annex 6 to this Regulation. Q apk,z – total heat losses for heating Whwhich shall be determined in accordance with Paragraph 81 of this Regulation. If a comparison of the energy rating results is unavailable, a further survey shall be carried out, in order to verify data or introduce such influencing lgn that have not been taken into consideration before.

For buildings in operation a measured and calculated energy rating shall be determined by using data regarding:. Utilisation of the Validation of a Building Calculation Model. Solar heat collecting areas shall be glazing, external nontransparent elements, internal walls and floors of verandas, as well as walls behind transparent cover or transparent insulation.
Heat accumulations and part of the heat lnn from the building, which depends on the thermal inertia of the building, shall be taken into consideration.

Internal heat from a ventilation system, which is not taken into consideration lbb determining an lbb temperature, may comprise dissipated heat from fan motors. When acquiring the calculated energy rating, the energy balance shall be divided:. Such internal heat sources like artificial lighting and electric appliances shall be assessed by using the accounting data of the consumed electricity, unless heating or cooling systems are also connected to the meter.
As concerns windows facing south barriers on both sides, two shading coefficients must be multiplied. Partitioning of a building into several parts shall not be necessary, if all of the following conditions refer to the building:. In order to adjust energy consumption according to climatic 0003-01, the values of the heating period duration and the average external temperature specified in Table 7 of LBN “Construction Climatology” shall be used.
When calculating the confidence interval of the weight, the ambiguity of density and moisture shall be taken into consideration.
Hourly data for assessing the annual energy use for heating and cooling. If an energy balance is being drawn up at the level of technical building systems or if the energy required for heating that has been calculated for the building is 030-01 than 50 kilowatt-hours per square metre of lnn area under calculation, a detailed calculation shall be carried out 0033-01 accordance with Standard LVS EN ISO For months containing “holiday” periods the energy required for heating and cooling shall be calculated separately for a continuous period and “holiday” period, and the results shall be interpolated linearly according to the ratio between “holiday” and occupied period time parts by using the following formulas:.
When using the steady-state method, dynamic effects, which shall be calculated by using correlation factors, shall be taken into consideration.
Classification of building constructions. Reduction factors for several screen types are specified in Table 2 of this Annex. The following methods shall be used for assessing measuring the internal temperature:. Total energy required lbj heating and cooling for the definite building zone shall be calculated by adding up the energy calculated for the period in accordance with Paragraphs and of this Regulation, taking into consideration a possible load for different heating or cooling parts:.
