When lbj necessary energy performance improvement measures, one or several scenarios of the building energy performance improvement shall be prepared, in which definite and mutually coordinated energy performance measures shall be specified.

If an assessment is carried out lnn using the energy accounting, the assessment period shall cover a wide at least month range of the average external temperatures. When using the dynamic method, the heat flow from solar heat sources in a definite building zone shall be calculated for each hour by using the following formula:. If changes made to 00-01 building affect the energy performance of the building up to 10 per cent, the previously obtained data may be used with an adjustment that is justified by appropriate calculations.

For separate zones, which have a common heating and cooling system, the energy required for heating and cooling shall be the sum of the required energy calculated for separate zones.

This increases the reliability that the energy saving calculation obtained through the planned energy performance improvement measures is accurate and that the planned energy performance improvement measures will provide the anticipated results in practice. For the calculation of energy required for heating and cooling the building shall be partitioned into:. Part of consumed energy that is smaller than 1 shall be allowed, if the suction ventilation releases heat right from the luminaires.

If the surface temperature of a heat source is close to the internal temperature of spaces, the actual transferred heat amount shall depend on the temperature difference of the heat source and external air temperature. Q dz,ieg – total heat gains for cooling Whwhich shall be determined in accordance with Paragraph 84 of this Regulation.

Heat balance shall be 003-001 during a sufficiently long time period – one month or the whole season. Procedure of the Validation of a Building Calculation Model. Conversion coefficient from net calorific value to gross calorific value. The following factors shall be taken into consideration in the cooling calculation when using the steady-state method:.

A apr – calculation area m 2which shall be determined in accordance with Sub-chapter 5. The translation of this document is outdated. For separate zones, which do not have a common heating and cooling system, the energy consumption in the building shall be the sum of the used energy calculated for separate zones.

Rural Sustainability Research Volume: Generation 003-0 typical solar radiation data for different climates of China. General Requirements for the Assessment Period.

For the calculation of energy required for heating and cooling the boundaries of a building shall be determined. The actual efficiency of planned energy performance improvement measures shall depend on the actual utilisation of a building.

Bills from electricity, gas and thermal energy suppliers or the building manager may be used for assessing lvn consumption of such energy carriers assessment period – full years. The generated TRY contains typical months from a number of different years. The value of the adjacent space, outdoor environment or zone temperature T 2,k shall be determined for the following situations:. Hourly data for assessing the annual energy use for heating and cooling.

The loss utilisation factor for cooling shall be determined by using the following formulas:. Energy that is produced is not auxiliary energy. Q dz,n – energy required for cooling, taking into consideration “holiday” periods Wh. Influence of the solar irradiation to the temperature of a space affected by the sun shall be taken into consideration when calculating solar heat gains.

Data required for energy performance calculations shall be obtained from the building technical documentation, performing surveys and measurements. F F – part of the frame area, ratio of the frame area to the total projected area of the glazed element, which shall be determined in accordance with Paragraph of this Regulation.

Climatic data shall be determined according to LBN “Construction Climatology”, using statistical data of meteorological information. Losses of a system can become internal thermal energy gains of a building, if they are recoverable.

If a measured energy assessment is used for validation of a building calculation model and initial data, the values obtained by means of calculations shall be compared with the measured values and the accuracy of the building calculation model shall be verified. Wind, solar, aerothermal, hydrothermal and sea energy, hydraulic energy.

T 1,apk – heating temperature set for the building or building zone o Cwhich shall be determined in accordance with Sub-chapter 5. The following solar shading regulation types shall be distinguished for the solar shading control:. A calculation area shall not include spaces in which it is not intended to maintain the internal temperature for example, non-heated cellars, attics, garages.

The gross calorific values of fuel shall be determined in accordance with Clause 2 of Annex 1 to this Regulation. When calculating the confidence interval of the weight, the ambiguity of density and moisture shall be taken into consideration.
