When applying the dynamic method, it shall be taken into consideration that during the heating season under the influence of the heat surplus the internal temperature exceeds the set-point temperature, which transmits the surplus heat with an additional transmission, ventilation and accumulation, if the mechanic cooling kbn not used.

Total heat losses through ventilation from a conditioned area shall be calculated for each month or season and each zone by using the following formulas:. Heat flow from the circulation of water in domestic hot water supply systems shall be determined by using the following formula:. Energy system losses shall include additional losses of the building heat due to uneven distribution of the room temperature and insufficient temperature control.

Delivered energy can be calculated or measured according to the definite energy use types. During the course of the verification of energy performance indicators the results of the measured and calculated energy rating shall be compared for all energy carriers.

A coefficient that comprises lgn of collecting areas and an area of collecting surfaces including effects from shading shall be the actual collecting area of solar heat. The level of liquid fuel in a tank shall be measured at the beginning and at the end of the assessment period by using a calibrated scale. The set-point temperature for a continuous cooling period shall 0033-01 used for all periods, if the 003-10 time constant, which has been determined in accordance with Paragraph of this Regulation, is threefold bigger than the longest reduced cooling period.

The adjusted internal thermal capacity of a building or building zone C lhn 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:. If there are unoccupied heating periods and the provisions referred to in Sub-chapter 5.

The 0003-01 calorific values of fuel shall be determined in accordance with Clause 1 of Annex 1 to this Regulation.

Classification of building constructions. As concerns windows on the east and west side for barriers at the north end, the shading correction shall not be required. For existing buildings the assessment of energy consumption for lighting shall be carried out on the basis of the lighting system luminaires and their control equipment output, assessment of the actual work hours and measured electricity consumption in the building. T 2,k – temperature for the element k in the adjacent space, environment or zone o Cwhich shall be determined 003-001 accordance with Paragraph 87 of this Regulation.

Energy required for heating and cooling shall be the main data of the energy balance of technical building systems. If hot 00301 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 lgn LVS EN F l – shading correction coefficient for the influence of the window position in accordance with Table 2 of Annex 6 to this Regulation.

Heat accumulations and part of the heat released from the building, which depends on the thermal inertia of the building, shall be taken into consideration. If a building is partitioned lbm zones, the sum of the conditioned bln calculation area of all the zones must be equal to the floor calculation area of the conditioned spaces of the whole building.

GDD – number of degree days in the assessment period determined in accordance with Paragraph 48 of this Regulation.

If an energy carrier is used in several technical building systems and for several purposes, the consumption of the energy carrier shall be distributed by technical systems and purposes.

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:. When acquiring the calculated energy rating, the energy balance shall be divided:.

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. T 1,dz – cooling temperature set for the building or building unit o C003–01 shall be determined llbn accordance with Sub-chapter 5.

Total energy required for heating and cooling for the definite building zone shall be calculated by lbnn up the energy calculated for the period in accordance with Paragraphs and of this Regulation, taking into consideration a possible load lbb different heating or cooling parts:. If part of technical building systems for example, boiler, cooler, cooling tower is located outside the building envelope, it shall be considered that they are inside the boundary, and the losses of the relevant system shall be taken into account.

One of the following methods shall be used for calculating the energy balance of a building:. 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.

Q 0003-01 – sum of internal heat gains in a definite month or season Wh pbn be determined for heating and cooling separately.

A calculated energy rating for a group of buildings may be carried out, if all of the following conditions are in force:. The time average flow level of the air flow element k shall be calculated by using the following formula:.

The reduction factor for cooling with unoccupied ln a samz,dz shall be calculated by using the following formula:. Duration of the calculation period t apk for the heating season shall be determined according to LBN “Construction Climatology”. Building boundaries comprise all the building lbm separating conditioned spaces from the outdoor environment air, ground or water and adjacent buildings or separate unconditioned spaces.
