Part of unused heat causes the necessity for cooling, in order to avoid raising of the internal temperatures over the set-point temperature. Following the identification of required energy performance improvement measures the standard energy rating shall be calculated for a modernised building. If the system equipment for example, boiler, cooler, cooling tower is located outside the building envelope, consumption lb an energy carrier for example, for gas, electricity, thermal energy, water shall be determined by using a meter.

T 1,apk – heating temperature set for the building or building unit o Cwhich shall be determined in accordance with Sub-chapter 5. This allows for assessing also the influence of the building management practice and changes of the occupants’ behaviour. For the calculation of energy required for heating and cooling the boundaries of a building shall be determined.

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.

Generation of typical solar radiation data for different climates of China. Issue 1 First Online: 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 adjusted internal thermal capacity of a ,bn or building zone C m shall be calculated by adding up the adjusted thermal capacities of all the building elements, which are in direct thermal contact with the internal air of the zone:.

The following formula shall be used for determining the set-point temperature for heating in one zone calculation:. Aerated concrete, cored ceramic brick, ceramsite concrete, wood concrete. Thermal energy from boiler rooms without cogeneration. Unused transmission and ventilation heat flow lb generated at time periods or intervals for example, at nightwhen cooling is not needed, but it can be necessary at other time periods or intervals for example, during the day 0033-01.

Q dz,ieg – total heat gains for cooling Whwhich shall be determined in accordance with Paragraph 84 of this Regulation. Irregular partly continuous heating and cooling shall be determined as continuous heating or cooling with an adjusted set-point temperature, if one or several of the following conditions are met:.


TRY selection process should include the most recent meteorological observations and should be periodically renewed to reflect the long-term climate change. System losses within the system boundaries shall be calculated in detail, while outside the system boundaries they shall be calculated by using conversion coefficients. Total solar energy transmittance of a transparent part of the element g g. T 1,apk – heating temperature set for the building or building zone obn Cwhich shall be determined in accordance with Sub-chapter 5.

When identifying necessary energy performance improvement measures, one or several scenarios of the building energy performance improvement shall be prepared, in which definite and mutually coordinated energy performance measures shall be specified.

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 verify data or introduce such influencing factors that have not been taken into consideration before.

Such a comparison of the calculated and actually obtained energy performance indicators shall be necessary for a precise assessment of the advantages of the identified energy performance measures calculated planned energy consumption after the implementation of the measures.

F l – shading correction coefficient for the influence of the window position in accordance with Table 2 of Annex 6 to this Regulation. 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.

Hot water consumption data for buildings for which an individual meter has been installed shall be obtained from the difference between two readings at the beginning and at the end of the assessment period. Q nov,apr – energy required for heating and cooling calculated for the assessment period Wh. The net calorific values of fuel shall be determined in accordance with Clause 1 of Annex 1 to this Regulation.

For buildings in operation a measured and calculated energy rating shall be determined by using data regarding:. Analysis of lbnn heating and cooling degree-days for Turkey. Useful area per person m 2. Q dz,n – energy required for cooling, taking lgn consideration unoccupied periods Wh.

Influence of the solar irradiation to the temperature of a lbbn affected by the sun shall be taken into consideration when calculating solar heat gains.

Generation of a test reference year for Alūksne, Latvia [2015]

For buildings to be designed energy consumption in a domestic hot water system shall be assessed in accordance with Section 5. Consumption of liquid fuel in the assessment period shall be the contents of the tank at the beginning of the assessment period, from which the contents of the tank at the end of the assessment period have been deducted and to which the amount of the fuel purchased in the assessment period has been added. An effective solar heat collecting area of the nontransparent part of building envelopes shall be calculated by using the following formula:.


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 simplified extrapolation calculation shall be used for calculating the amount of an energy carrier, which is used for heating or cooling during the whole year. Energy system losses shall be determined as total losses, adding the system losses recovered from the system. Heat balance shall be calculated during a sufficiently long time period – one month or the whole season.

Q apk,n,uzt – energy required for heating in a “holiday” period, assuming that the set-point temperature is controlled on all days of the month Wh.

Duration of a heating and cooling season according to the running periods of the relevant system components shall be determined in accordance with Sub-chapter 5.

Ēkas energoefektivitātes aprēķina metode

If in the course of construction deviations from the initial building design affect the energy performance indicators of a building, then, lnb putting the building into operation, an adjustment of calculations shall be carried out, 0003-01 into consideration the actual properties of the outer building envelope and technical building systems.

Data that cannot be obtained directly shall be obtained by using a calculation or the values specified in laws and regulations and standards. 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.

Rural Sustainability Research Volume: Q apk,ieg – total heat gains for heating Whwhich shall be determined in accordance with Paragraph 82 of this Regulation. When calculating the confidence interval of the weight, the ambiguity of density and moisture shall be taken into consideration.

The boundary of an energy rating for energy carriers gas, electricity, thermal energy and water shall be a meter, while for liquid and solid energy resources – the boundary of the storage system. Losses of a system can become internal thermal energy gains of a building, if they are recoverable.
