Q sol – sum of solar heat gains in the calculation period Whwhich shall be determined in accordance with Sub-chapter 5. Q apk,n,i – energy required for heating in the definite zone in the calculation period i per hour or month Whwhich shall be determined in accordance with Sub-chapter 5.
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 For buildings to be designed energy consumption in a domestic hot water system shall be assessed in accordance with Section 5.
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.
Sign in to annotate. Individual buildings for example, schools substantially reduce the energy required for heating or cooling during the “holiday” heating or cooling period.
Switching off of the thermostat may not be applied for lowering the internal temperature, because it depends on the building inertia 00-301 release from the building.
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 bln. GDD 1 – standard number of degree days that determined in accordance with Paragraph 48 of this Regulation. If hot water is not metered, the consumption thereof shall be assessed according to the 003–01 of occupants, building utilisation type and average hot water consumption data, using the data referred to in standards LVS EN Energy required for heating and cooling shall be the main data of the energy balance of technical building systems.
A coefficient that comprises characteristics of collecting areas and an area of collecting surfaces including effects from shading shall be the actual collecting area of solar heat.
Q dz,n,uzt – energy required for cooling in a “holiday” period, assuming that the set-point temperature is controlled on all days of the month Wh. The following formula shall be used for determining the set-point temperature for cooling in one zone calculation:. The actual duration of the heating season shall be used for the model validation in accordance with Sub-chapter 6.
Climatic data shall be determined according to LBN “Construction Climatology”, using statistical data of meteorological information. Confidence intervals shall be assessed for all the data used. The following solar shading regulation types shall be distinguished for the solar shading control:. Q iek – sum of internal heat gains lbh a definite month or season Wh shall be determined for heating and cooling separately. An energy rating, when determining annual energy consumption, shall include the technical building systems, which ensure:.
Energy system losses shall be determined as total losses, adding the system losses recovered from the system. The difference between an assessment that has been obtained prior to energy performance improvement measures and an assessment that has been 003-011 after them shall be the effect of the relevant measures on energy consumption.
The flow speed in a burner shall be measured before the first reading and after each setting or cleaning. A s,k – effective collecting area 003-01 a glazed 0030-1 m 2. Q iek – sum of internal heat gains in the calculation period Whwhich shall be determined in accordance with Sub-chapter 5.
Losses 0003-01 a system can become internal thermal energy gains of a building, if they are recoverable.

Unused transmission and ventilation heat flow is 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. Building boundaries comprise all the building elements separating conditioned spaces from the outdoor environment air, ground or water and adjacent buildings or separate unconditioned spaces. If an assessment is carried out by using the energy accounting, the assessment period shall cover a wide at least month range of the average external temperatures.
Q dz,z – total heat losses of the cooling part through transmission and ventilation Whwhich shall be determined in accordance with Sub-paragraph If an assessment period is shorter than five years, an adjustment of the energy consumption due to climatic conditions shall be performed. For energy carriers that are used for heating or cooling the extrapolation shall be carried out by using the energy accounting or simplified calculation in accordance with Paragraph 42 of this Regulation.
Adjustment of energy consumption due to climatic conditions shall be calculated in accordance with Paragraphs 47 and 48 of this Regulation.
Data Obtaining and Adjustment Extrapolation. 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, 003-01 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 003-01 a modernised building.
According to the steady-state method heat gains from internal sources in a definite building zone in a definite month or season shall be calculated by using the following formula:.

The carbon dioxide CO2 emission factors are specified in Annex 1 to this Regulation. Energy consumption for all energy carriers must be assessed in an equal time period. Conversion coefficient from net calorific value to gross calorific value. A calculated energy rating shall be determined in accordance with Chapter 5 of this Regulation. Taking into consideration that separate measures can correlate for example, an increased thermal insulation or passive solar heat gains can lower the efficiency of a boilerthe effects obtained in the course of each individual measure may not be added.
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. The following formula shall be used for determining the set-point temperature for heating in one zone calculation:.

When using the dynamic method, the heat flow from solar heat sources in a definite building zone shall be calculated for each hour by using the following formula:. The gain utilisation factor shall be determined regardless of the heating system features, assuming that the temperature is fully controlled and is limitlessly flexible.
Validation verification of a building calculation model shall be carried out according to the following procedures:. Solar heat gains in a building zone for a definite month or season shall be calculated by using the following formula:. For buildings in operation a measured and calculated energy rating shall be 003-1 by using data regarding:. For the calculation of energy required for heating and 00-01 the building shall be partitioned into:. Thermal energy gains include internal heat gains and solar heat gains.
Q apk,n,kopa,z – total energy required for the heating of the building zone zwhen using a combination of definite systems Whwhich shall be ,bn in accordance with Paragraph of this Regulation. 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.
