Generation of a Test Reference Year for Alūksne, Latvia

For each proposed scenario contains particular energy performance improvement measures the initial data shall be changed according to the planned energy performance improvement measures and the calculation shall be carried out anew. If there is a common accounting of thermal energy for the heating and domestic hot water systems in a building, then, on the basis of data regarding the energy and hot water consumption in the period when heating is not used, the following calculation simplification shall be admissible for existing buildings – the energy consumption in the water supply system for heating and circulation of hot water for a year period shall be calculated by using linear extrapolation.

Verification of Energy Performance Indicators. TRY selection process should include the most recent meteorological observations and should be periodically renewed to reflect the long-term climate change.

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.

The set-point temperature Tuzst,apk. Running time part f iek. The gain utilisation factor shall be determined regardless of the heating system features, assuming that the temperature is fully controlled and is limitlessly flexible. Energy consumption for heating, cooling, heat transmission losses and heat losses through ventilation shall be assessed in accordance with Chapters III, IV, V and VI of this Regulation, taking into consideration internal and solar heat gains and recoverable losses of the technical building system.

Republic of Latvia Cabinet Regulation No. 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:. 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.


Utilisation of the Validation of a Building Calculation Model. Q nov,apr – energy required for heating and cooling calculated for the assessment period Wh. Internal heat from a ventilation system, which is not taken into consideration when determining an incoming temperature, may comprise dissipated heat from fan motors. Heat gains from solar heat sources elements of building constructions and unconditioned spaces irradiated by the sun generate from solar irradiation existing at the location of a building, as well as orientation of collecting surfaces and areas, constant shading, solar irradiation transmittance and absorption, and thermal heat transfer.

Total heat losses through ventilation from a conditioned area shall 0003-01 calculated for each month or season and each zone by using the following formulas:. The value of the adjacent space, outdoor environment or zone temperature T lbm shall be lgn for the following situations:.

The value of the obn energy transmittance of a transparent part is affected by a screen curtains and blindswhich substantially reduces the solar energy transmittance. T 2,pieg – element k air flow supply temperature o Cincluding buildings or building zones with ventilation obn infiltration, which shall be determined in accordance with Paragraph 89 of this Regulation.

Rural Sustainability Research Former: 0003-01 flow from the circulation of water in domestic hot water supply systems shall be determined by using the following formula:. Internal heat gains shall be any heat that is generated by internal sources and is used for space heating, space cooling or preparation of hot water. For the calculation of energy required for heating and cooling the building shall be partitioned into:.

Thermal lgn gains include internal heat gains and solar heat gains. When using the dynamic method, thermal resistance, thermal capacity output and heat gains from solar and internal thermal resources in the building or building zone shall be taken into consideration. A calculation area shall not include spaces in which it is not intended to maintain the internal temperature lbj example, non-heated cellars, attics, garages.

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 factors that have not been taken into consideration before.

Heat flow from other lighting elements shall be calculated taking into consideration the function of the building, utilisation of lighting and purpose 003-01 the calculation.

Domestic hot water systems, generation”. General Requirements for the Assessment Period. This Regulation prescribes the methodology for calculating the energy performance of a building.

Useful area per person m 2. Primary energy factors for the part of non-renewable energy resources are specified in Table 2 of this Annex. Only energy delivered by solar energy installations and auxiliary energy, which is required for heat delivery to a building from an energy source, shall be taken into consideration in the energy balance.

The average temperature of a ventilated zone shall be assessed when the exhaust fan is switched on. Q dz,n – energy required for cooling, taking into consideration unoccupied periods Wh. As concerns windows facing south barriers on both sides, two shading coefficients must be multiplied.

The generated TRY contains typical months from a number of different years. Floor area located within the boundaries of the building shall be a conditioned floor calculation area of the building A apr.

Such internal heat sources like the number of people and lbb of their presence in the building shall be assessed by surveying the building, or obtained from the building owner or manager.

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.

Q dz,n,j – energy required for cooling in the definite zone in the calculation period j per hour or month Whwhich shall be calculated in accordance with Sub-paragraph 5. The quality of a validated data set shall be the balance between the costs for the data obtaining collection and the appropriate accuracy. As concerns windows on the east and west side for barriers at the north end, the shading correction shall not be required. Q dz,z – total heat losses of the cooling part through transmission and ventilation Whwhich shall be determined in accordance with Sub-paragraph Data Obtaining and Adjustment Extrapolation.

Energy can be imported or exported through the building boundary. Wind, solar, aerothermal, hydrothermal and sea energy, hydraulic energy. It shall be calculated by using the following formula:.
