A s,k 003-011 surface k with a definite orientation and slope angle effective collecting area in the relevant zone m 2which shall be determined in accordance with Paragraphs glazing and nontransparent building elements of this Regulation.

For buildings to be designed the assessment of energy consumption for lighting shall be carried out in accordance with Standard LVS EN The following solar shading regulation types shall be distinguished for the solar shading control:. E per – amount of the energy 0033-01 that has been consumed in the accounting period of the energy carrier kg, m 3 or Wh.

When surveying a building, the actual internal temperature of the building shall be assessed, since in practice it often differs from the designed temperature, and it substantially affects the consumption indicators of the energy used for cooling and heating.

The verification shall be repeated with a new initial data set. Thermal energy gains include internal heat gains and solar heat gains. If heating is irregular or switched off, the influence of the building thermal inertia shall be taken into consideration separately. 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.

If gas is delivered in gas containers, fuel shall be assessed by adding up the number of the used containers volume of the containers shall be taken into account. 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. Energy that is produced is not auxiliary energy. 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.

Energy required for heating and cooling calculated for a year Q kop,apr shall be calculated by using the 4 th formula and individually calculating the energy required for heating and cooling that has been calculated by using the 5 th and 6 th formula:.

Useful area per person m 2. Q dz,ve – total heat losses for cooling through ventilation Whwhich shall be determined in accordance with Sub-chapter 5. Q dz,pr – total heat losses for cooling through transmission Whwhich shall be determined in accordance with Sub-chapter 5.


Partitioning of a building into several parts shall not be necessary, if all of the following conditions refer to the building:.

Generation of a test reference year for Alūksne, Latvia

Other energy-consuming systems, which are built in the building and ensure functional needs of the building for example, elevators, escalators and industrial technological equipmentshall be taken into consideration in calculations of the energy rating, however, they shall not be taken into consideration when determining annual energy consumption indicators.

An effective solar heat collecting area of the nontransparent part of building envelopes shall be calculated by using the following formula:.

If heating, cooling and ventilation systems are combined, the total energy use for heating Q apk,sist and the total energy use for cooling Q dz,sist including system losses shall be determined as the required energy function for heating and cooling according to the relevant standards for heating and cooling systems LVS EN A lbm energy rating for a group of buildings may be carried out, if all of the following conditions are in force:.

Generation of typical meteorological year for different climates of China. 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 lvn as orientation of collecting surfaces and areas, constant shading, solar irradiation transmittance and obn, and thermal heat transfer.

A s,k – effective collecting area of a glazed element m 2.

003-001 Proceedings of the Latvia University of Agriculture. Provisions for an Operating Mode of Internal Spaces. The primary energy consumption indicator shall be calculated from the delivered and exported energy for each energy carrier primary energy factors for non-renewable part of energy resources shall be accepted in accordance with Clause 3 of Annex 1 to this Regulation by using the following formula:. The adjusted internal 0003-01 capacity of a building or building zone C m shall be calculated by adding up the adjusted thermal capacities of all the building elements, which lbb in direct thermal contact with the internal air of the zone:.

Optical properties of the screen. A source of cold that releases heat from a building shall be a heat source with a negative sign.

It shall be taken into 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. Solar heat collecting areas shall be glazing, external nontransparent elements, internal walls and floors of verandas, as 003-01 as walls behind transparent cover or transparent insulation.

GDD 1 – standard number of degree days that determined in accordance with Paragraph 48 of this Regulation. T 1,dz – cooling temperature set for the building or building unit o Cwhich shall be determined in accordance with Sub-chapter 5. Total energy required for heating and cooling for the definite building zone shall be calculated by adding up the energy calculated for the period in accordance with Paragraphs and of this Regulation, taking into consideration a possible load for different heating or cooling parts:.

T 1,apk – heating temperature set for the building or building unit o Cwhich shall be determined in accordance with Sub-chapter 5. Since meteorological conditions vary significantly from year to year, there is a need to create a test reference year TRYto represent the long-term weather conditions over a year. In order to assess the energy saving obtained from planned energy performance improvement measures, the same building calculation model that has been used when assessing the calculated energy performance shall be used.

If an assessment period is not the full number of years, the annual energy consumption shall be obtained by using the extrapolation method. The average temperature of a ventilated zone shall be assessed when the exhaust fan is switched on.

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

For energy carriers that are used for heating or cooling lb extrapolation shall be carried out by using the energy accounting or simplified calculation in accordance with Paragraph 42 of this Regulation. As concerns windows on the east and west side for barriers at the north end, the shading correction shall not be required.

Thermal energy that has been recovered in the system shall not be thermal energy losses, but thermal 0003-01 gains. 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:. Gross calorific values of fuel shall be determined by using the net calorific coefficients of fuel, multiplying them by the conversion coefficients, which are specified in 003-011 1 of this Annex.

Individual buildings for example, schools lgn reduce the energy required for heating or cooling during the “holiday” heating or cooling period. 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.
