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:.
The set-point temperature Tuzst,dz. Q apk,n,kopa,zs – total energy required for the heating of all building zones zswhen using a combination of definite systems Wh.
Hot water lbm 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.
For the calculation of energy required for heating and cooling the boundaries of a building shall be determined. Consumption of liquid fuel in the assessment period shall be the ln of the tank at the kbn of the assessment period, from which the contents of lnn 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.
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.
Other energy-consuming systems, which are built in the building and ensure functional needs of the building for example, elevators, escalators and industrial technological equipment lnb, shall be taken into consideration in calculations of the energy rating, however, they shall not be taken into consideration when determining annual energy consumption indicators.
Following the identification of required energy performance improvement measures the standard energy rating shall be calculated for a modernised building. The actual duration of the heating season shall be used for the model validation in accordance with Sub-chapter 6.
The gross calorific values of fuel shall be determined in accordance with Clause 2 of Annex 1 to this Regulation. A system boundary is related to the object under assessment for example, building, building unit, apartment and comprises all elements of the interior and exterior, which are related to 00-01 building where the energy is produced or 0030-1. 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.
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. If changes have been made to a building in the assessment period, which affect the energy performance thereof for more than 10 per cent, the previously obtained data may not be used for the assessment of the energy performance of the building.
The set-point temperature Tuzst,apk.
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 Table 1 of this Annex.
If a building is partitioned in zones, the sum of the conditioned floor calculation area of all the zones must be equal to the floor calculation area of the conditioned spaces of the whole building. Energy required for heating and cooling shall be the main data of the energy balance of technical building systems.

Q dz,n – energy required for cooling, taking into consideration unoccupied periods Wh. Q apk,z – total heat losses 0030-1 a heating part Whwhich shall be determined in accordance with Sub-paragraph Internal heat gains – heat flow part from the occupants and appliances in residential buildings. Only energy delivered by solar energy installations and auxiliary energy, which is required for heat delivery to a building from an lbb source, shall be taken into consideration in the energy balance.
Total energy required for heating and cooling for the definite building zone shall be calculated by adding up the energy calculated 030-01 the period in accordance with Paragraphs and of this Regulation, taking into consideration a possible load for different heating or cooling parts:. Data that cannot be obtained directly shall be obtained by using a calculation or the values specified in laws and regulations and standards.

Partitioning of a building into several parts shall not be necessary, if all of the following conditions refer to the building:. When using the dynamic method, the heat flow from internal heat sources for a definite building zone shall be calculated for each hour by using the following formula:.
When assessing internal heat sources, it shall be taken into consideration that not all the energy used for lighting is an internal heat source for example, if lighting is located outside the building or the heat is partially released.
In order to adjust energy consumption according to climatic conditions, the values of the heating period duration and the average external temperature specified in Table 7 of LBN “Construction Climatology” shall be used. Predicting performance of a renewable energy-powered microgrid throughout the United States using typical meteorological year 3 data.
Rural Sustainability Research Former: Heat balance shall be calculated during a sufficiently long time period – one month or the whole season. Consumed electricity bills shall be used for assessing the consumption of energy used for artificial lighting, unless other systems are also connected to the meter for example, cooking, heating, cooling systems.

The measured energy consumption for heating and cooling shall be adapted according to the local climatic conditions at the place of location of a building.
It shall be determined on the basis of measurements obtained during at least one month. Energy consumption for all energy carriers must be assessed in an equal time period. Type of the building utilisation. Also building envelopes made of polymers and other translucent materials that serve as glazed elements shall be considered to be glazed elements. Active solar systems for example, sun collectors shall be part of the technical building system. TRY selection process should include the most recent meteorological observations and should be periodically renewed to reflect the long-term climate change.
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. F l – shading correction coefficient for the influence of the window position in accordance with Table 2 of Annex 6 to this Regulation.
If heating is irregular or switched off, the influence of the building thermal inertia shall be taken into consideration separately.
Total energy performance indicators of a building shall be determined following the calculation of ln required calculated and used measured energy carriers. 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.
003-01 calculating the confidence interval of the weight, the ambiguity of density and moisture shall be taken into consideration. Calculation for heating and cooling shall be carried out according to the following procedures:. Wind, solar, aerothermal, hydrothermal and sea energy, hydraulic energy. The building calculation model with an output initial data set shall be used for this purpose, taking into 003-011 the influence of the energy performance improvement measures on the initial data set determined by the standard.
When acquiring the calculated energy rating, the energy balance shall be divided:. Sign in to annotate. Internal heat gains shall be heat gains from internal heat sources, including negative heat gains from a space to sources of coldness.
