Generation of a Test Reference Year for Alūksne, Latvia : Rural Sustainability Research

The set-point temperature Tuzst,apk. The value of an individual air flow k supply temperature T 2,pieg,k shall be accepted in the following way:. The total auxiliary energy required for ventilation systems shall be determined according to the Standard LVS EN TRY selection process should include the most recent meteorological observations and should be periodically renewed to reflect the long-term climate change.

For existing buildings the energy consumption in a domestic hot water system shall be assessed on the basis of the measured data regarding the heat consumption and hot water consumption. The values indicated in Table 3 of this Annex are validated for barriers on the south side.

Predicting performance of a renewable energy-powered microgrid throughout the United States using typical meteorological year 3 data. 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. The reduction factor for cooling with unoccupied periods a samz,dz shall be calculated by using the following 00301.

Floor area located within the boundaries of the building shall be a conditioned floor calculation area of the building A apr. Mobile sun shading reduction coefficient f l,int depending on the month and orientation of the glazed surface.

The following information shall be required for the assessment of the technical building systems of a building:. Rural Sustainability Research Former: The time constant t of a building or building zone characterises the internal thermal inertia of a conditioned zone in the heating and cooling period respectively. For energy carriers that are used, if the average output of equipment is constant and the extrapolation is linear, the amount shall be calculated by using the following formula:.


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 lgn according to the ratio between “holiday” and occupied period time parts by using the following formulas:. For the calculation of energy required for heating and cooling the boundaries of a building shall be determined. In calculations of the cooling period it shall be taken into consideration that the set-point internal temperature lowers below the set-point 003-001.

Heat balance shall be calculated during a sufficiently long time period – one month or the whole season. The difference between an assessment that has been obtained prior to energy performance improvement measures and an assessment that has been obtained after them shall be the effect of the relevant measures on energy consumption.

Validation verification of a building calculation model shall be carried out according to the following procedures:. It shall be taken obn consideration in the calculation of the internal and solar heat gain utilisation for heating that only part of the gains is used when reducing the energy required for the heating of a building, if the internal temperature is raised over the set-point temperature.

Heat flows between the zones shall be taken into consideration, if it is necessary for the assessment of recommended energy performance measures or for getting additional results. Hourly data for assessing the annual energy use for heating and cooling. An effective solar heat collecting area of the nontransparent part of building envelopes shall be calculated by using the following formula:.

Losses and auxiliary energy comprise energy generation, transport, control, distribution, storage and emission. Analysis of variable-base heating and cooling degree-days for Turkey. Q apk,pr – total heat losses for heating through transmission Whwhich shall be determined in accordance with Sub-chapter 5.

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.


Boundaries of an energy rating and the energy flow scheme are specified in Annex 2 to this Regulation. Part of consumed energy that is smaller than 1 shall be allowed, if the suction ventilation releases heat right from the luminaires.

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 energy content of solid fuel for example, coal, wood depends on the quality and density thereof. Q apk,n,N – energy required for heating in a continuous heating period assuming that the set-point temperature is controlled on all days of the month Wh.

Conversion coefficient from net calorific value to gross calorific value. 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 003-01 Paragraph of this Regulation, is threefold bigger than the longest reduced cooling period.

Switching off of the thermostat may not be applied for lowering the internal temperature, kbn it depends on the building inertia heat release from the building.

If lb assessment period is not the full number of years, 00-01 annual energy consumption shall be obtained by using the extrapolation method.

Q dz,ieg – total heat gains for cooling Whwhich shall be determined in accordance with Paragraph 84 of this Regulation. If at least one of the conditions referred to in Paragraph 64 of this Regulation is not met, the building shall be partitioned into zones and one zone calculation conditions shall be applied to each zone. The actual duration of the heating season shall be determined according to the number of hours in the season, when the relevant system was running for example, pumps, fans.

This Sub-paragraph shall also be applicable to cooling systems Q dz,n, iQ dz,sist, i and Q dz,sist,pap, i.
