Q iek – sum of internal heat gains in a definite month or season Wh shall be determined for heating and cooling separately.

Rural Sustainability Research Volume: Useful area per person m 03-01. A calculated energy rating shall be determined in accordance with Chapter 5 of this Regulation.

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. If an assessment period is not the full number of years, the annual energy consumption shall be obtained by using the extrapolation method. The total auxiliary energy required for ventilation systems shall be determined according to the Standard LVS EN Climatic data shall be determined according to LBN “Construction Climatology”, using statistical data of meteorological information.

Data Obtaining and Adjustment Extrapolation. E per – amount of the energy carrier that has been consumed in the accounting period of the energy carrier kg, m 3 or Wh. The total ventilation heat loss coefficient for each month or season and each heating or cooling zone shall be calculated by using the following formula:.

The total heat loss coefficient of a building or building zone shall be calculated by using the following formula:. Rural Sustainability Research Former: 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 carbon dioxide CO2 emission factors are specified in Annex 1 to this Regulation. Q apk,z – total heat losses for a heating part Whwhich shall be determined in accordance with Sub-paragraph Running time part f iek.

If a measured energy rating is based on energy consumption data obtained in a period that is shorter than five full years, an adjustment of the measured energy performance due to climatic conditions shall be required for ensuring the correspondence between the consumed energy measured in the measurement period and the average local climatic conditions.

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 using the dynamic method, the heat flow from solar heat sources in a 003-0 building zone shall be calculated for each hour by using the following formula:. Boundaries of an energy rating and the energy flow scheme are specified in Annex 2 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. The generated TRY contains typical months from a number of different years. Energy system losses shall include additional losses of the building heat due to uneven distribution of the room temperature and insufficient temperature control. obn

F l – shading correction coefficient for the influence of the window position in accordance with Table 2 of Annex 6 to this Regulation. Generation of typical meteorological year for different climates of China.

Also building envelopes made of polymers and other translucent materials that serve as glazed elements shall be considered to be glazed elements. An energy balance shall include energy, which is delivered by the energy production equipment for the building consumption, and auxiliary energy required for delivering to the building energy from heat sources for example, from a solar collector. Losses and auxiliary energy comprise energy generation, transport, control, distribution, storage and emission.

Individual buildings for example, schools substantially reduce the energy required for heating or cooling during the “holiday” heating or cooling 003–01.

Q dz,ieg – total heat gains for cooling Whwhich shall be determined in accordance with Paragraph 84 of this Regulation. 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. The average temperature of a ventilated zone shall be assessed when the exhaust fan is switched lbnn.

F p – shading correction coefficient for the influence of the overhang and shed in accordance with Table 2 of Annex 6 to this Regulation.

The set-point temperature Tuzst,dz. T 1,apk – heating temperature 0030-1 for the building or building zone o Cwhich shall be determined in accordance with Sub-chapter 5. Q dz,n,N – energy required for cooling in a continuous cooling period, assuming that the set-point temperature is controlled on all days of the month Wh.

The set-point temperature for a continuous cooling period shall be used for all periods, obn the building time constant, which has been determined in accordance with Paragraph of this Regulation, is threefold bigger than the longest reduced cooling period. Adjustment of energy consumption due to climatic conditions shall be calculated in accordance with Paragraphs 47 and 48 of this Regulation.

In order to assess the energy saving obtained from planned energy performance improvement measures, the same building calculation 003-001 that has been used when assessing the calculated energy performance shall be used. Taking into consideration that in general characteristics change both per hour and during a year, the appropriate average and constant values must be chosen, which conform to, for example, heating, cooling or summer comfort calculations.

Small up to five per cent of the zone area non-heated spaces unconditioned spaces may be included into conditioned heated zones and considered to be conditioned.

The energy balance of a building shall also include the energy recovered in the buildings from different technical building systems. Energy consumption and calculation initial data collected in the assessment period must relate to the equal time periods.

Generation of a Test Reference Year for Alūksne, Latvia

Q apk,pr – total heat losses for heating through transmission Whwhich shall be determined in accordance with Sub-chapter 5. Q dz,n,kopa,z – total energy required for the cooling of the building zone zwhen using a combination of definite systems Whwhich shall be determined in accordance with Paragraph of this Regulation.

Analysis of typical meteorological years in different climates of China. As concerns windows on the east and west side for barriers at the north end, the shading correction shall not be required.
