Q dz,z – total heat losses of the cooling part through transmission and ventilation Wh 003-10, which shall be determined in accordance with Sub-paragraph For buildings in operation a measured lbb calculated energy rating shall be determined by using data regarding:. T 1 – average set-point temperature in the assessment heating or cooling period o C.

Predicting performance of a renewable energy-powered microgrid throughout the United States using typical meteorological year 3 data. Confidence intervals shall be assessed for all the data used. A validated building data set shall be used for this purpose, which is the output data of the building calculation model, in which one or several output data are adapted on the basis of the actual data, in order for the calculation results, when using the model, not to differ from the data of actual measurements.

This Sub-paragraph shall also be 03-01 to cooling systems Q dz,n, 003-10Q dz,sist, i and Q dz,sist,pap, i. As concerns windows on the east and west side for barriers at the north end, the shading correction shall not be required.

This Regulation prescribes the methodology for calculating the energy performance of a building. Calculation for heating and cooling shall be carried out according to the following procedures:.

Q dz,n – energy required for cooling, taking into consideration unoccupied periods Wh.

In order to obtain the weight of solid fuel, the measured volume shall be multiplied by the density of the fuel. If a comparison of the energy rating results is unavailable, a further survey shall be carried out, in order to 00301 data or introduce such influencing factors that have not been taken into consideration before.


If in the course of construction deviations from the initial building design affect the energy performance indicators of a building, lnb, when putting the building into operation, an adjustment of calculations shall be carried out, taking into consideration the actual properties of the outer building envelope and technical building systems. Issue 1 First Online: The set-point temperature for a continuous cooling period shall be used for all periods, if the building time constant, which has been determined in accordance with Paragraph of this Regulation, is threefold bigger than the longest reduced cooling period.

Energy consumption for all energy carriers must be assessed in an equal time period.

Solar heat gains in a building zone for 0003-01 definite month or season shall be calculated by using the following formula:. F l – shading correction coefficient for the influence of the window position in accordance with Table ,bn of Annex 6 to this Regulation. For energy carriers that are used for heating or cooling the extrapolation shall be carried out by using the energy accounting or simplified calculation in accordance with Paragraph 42 of this Regulation.

A calculated energy rating for a group of buildings may be carried out, if all of the following conditions are in force:. 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” lbm occupied period time parts by using the following formulas:.

Adjustment of energy consumption, using the degree days, shall be carried out by using the following formula:.

The net calorific values of fuel shall be determined in accordance with Clause 1 of Annex 1 to this Regulation. The following shall be taken into consideration for determining the heat balance of a building or its zones:.

Latvia State Standard The dynamic method models thermal resistance, thermal capacity and internal and solar heat gains in the building or building zones. F h – shading correction coefficient for the influence of the horizon in accordance with Table 1 of Annex 6 to this Regulation. Q dz,n,kopa,z – total energy required for the cooling of the building zone zwhen using a combination of definite systems Whwhich shall be determined in accordance with Paragraph of this Regulation. Proceedings of the Latvia University of Agriculture.


If a burner runs with a fixed output without modulation and is equipped with a burning time meter, consumption of the fuel shall be the difference between two readings that have been performed at the beginning and at the end of the assessment period, multiplied by the flow speed in the burner. Energy Conversion and Management.

For buildings in operation a measured and calculated energy rating shall be validated in accordance with Chapter 6 of this Regulation. The methodology shall be used in drawing up an energy balance at the building level.

Q dz,n,kopa,zs – total energy required for the cooling of all building zones zswhen using a combination of definite systems Wh. If an assessment period is not the full number of years, the annual energy consumption shall be obtained by using the extrapolation method. Provisions for an Operating Mode of Internal Spaces. Conditions for Calculating Solar Heat Gains. If hot water is not metered, the consumption thereof shall be assessed according to the number of occupants, building utilisation type and average hot water consumption data, using the data referred to in standards LVS EN The total system energy bln heating, cooling and ventilation systems lnb be calculated according to the following combinations:.

When calculating the confidence interval of the lb, the ambiguity of density and moisture shall be taken into consideration.

Specification of Boundaries and Zones of a Building. As a result of calculations of several zones with thermal influence between the zones or without itthe total energy required for heating and cooling for combining operation of definite heating, cooling and ventilation systems in different zones shall be the required energy sum in the zones zsfor which a combination of different systems is used:.

The measured energy consumption for heating and cooling shall be adapted according to the local climatic conditions at the place of location of a building.
