In this paper two different TRY data models were generated and compared: Indicators required for the calculated energy rating shall be obtained according to the following procedure:. Republic of Latvia Cabinet Regulation No.
Part of unused heat 0003-01 the necessity for cooling, in order to avoid raising of the internal temperatures over the set-point temperature. It shall be used for calculating heat balance in short time periods for example, per hour.
The flow speed in a burner shall be measured before the first reading and after each setting or cleaning. Losses and auxiliary energy comprise energy generation, transport, control, distribution, storage and emission.

For buildings to be designed, reconstructed or renovated the following output data shall be applied when acquiring the calculated energy rating at the design stage:. E nov – amount of the energy carrier used for heating and cooling in the assessment period kg, m 3 or Wh.
Dissipated heat of the incoming air shall comprise the raising of the incoming temperature, which shall be determined according to the relevant air flow and ventilation system Standard LVS EN lb If changes made to the building affect the energy performance of the building up to 10 per cent, the previously obtained data may be lbj with an adjustment that is justified by appropriate calculations.
The following shall 030-01 taken into consideration for determining the heat balance of a building or its zones:.
Ēkas energoefektivitātes aprēķina metode
The actual duration of the cooling season shall be determined according to the number of hours in the season, when the relevant system was running for example, pumps, fans. Validation verification of a building calculation model shall be carried out, in order to ascertain that the energy performance indicators obtained in the calculations conform to the actually obtained ones. Verification of Energy Performance Indicators. Q dz,ve – total heat losses for cooling through ventilation Whwhich shall be determined in accordance with Sub-chapter 5.
Energy required for heating and cooling shall be the main data of the energy balance of technical building lvn. Total solar energy transmittance of a transparent part of the element g g. An adjacent unconditioned space shall be an unconditioned space over the boundaries of the heating and cooling energy consumption calculation zone.
When acquiring the calculated energy rating, lbh energy balance shall be divided:. Consumption of energy carriers electricity, gas, thermal energy measured with a meter shall be the difference between two meter readings that shall be read at the beginning and at the end of the assessment period.
The total system energy for heating, cooling and ventilation systems shall be calculated according to the following combinations:. Dynamic parameter values of the time constant, thermal mass coefficient and internal thermal capacity of a building shall be calculated in accordance with the procedures laid down in this Sub-chapter or accepted in accordance with Annex 7 to this Regulation.
When using the dynamic method, the heat flow from internal heat sources for a definite building zone shall be calculated for each hour by using the following formula:. Floor area located within the boundaries of the building shall be a conditioned floor calculation area of the building A apr. Bills from electricity, gas and thermal energy suppliers or the building manager may be used for assessing the consumption of such energy carriers assessment period – full years.
Energy can be imported or exported through the building boundary. The dynamic method models thermal resistance, thermal capacity and internal and solar heat gains in the building or building zones. For buildings in operation a measured and calculated energy rating shall be determined by using data regarding:. The influence of the solar irradiation in addition to the temperature of the sun influence shall be taken into consideration when calculating solar heat gains. Solar heat collecting areas shall be glazing, external nontransparent elements, internal walls and floors of verandas, as well kbn walls behind transparent cover 003-10 transparent insulation.
Q apk,n,kopa,zs – total energy required for the heating of all building zones zswhen using a combination of definite systems Wh.
Generation of a test reference year for Alūksne, Latvia 
Energy system losses shall include additional losses of the building heat due to uneven distribution of the room temperature and insufficient temperature control.
Heat balance shall be calculated during a sufficiently long time 0003-01 – one month or the whole season. Q apk,ieg – total heat gains for a heating part Whwhich shall be determined in accordance with Sub-paragraph Ln required for additional heat humidification shall not be included in the calculation. Small up to five per cent of the zone area non-heated spaces unconditioned spaces may be included into conditioned heated kbn and considered to be conditioned. Analysis of variable-base heating and cooling degree-days for Turkey.
An economic evaluation of heating and other energy delivering or consuming systems shall be performed according to Standard LVS EN The gain utilisation factor for heating shall be determined by using the following formulas:.
When calculating the confidence interval of the weight, the ambiguity of density and moisture shall be taken into consideration. If a building is partitioned into several zones and the heat flow between the zones is taken into consideration, then also any type of heat transmission including air movement shall lvn taken into consideration and the calculation shall be performed in accordance with Annex B to Standard LVS EN ISO
