If the system equipment for example, boiler, cooler, cooling tower is located outside the building 003–01, consumption of an energy carrier for example, for gas, electricity, thermal energy, water shall be determined by using a meter. Generation of a typical meteorological year for Damascus zone using the Filkenstein—Schafer statistical method.
Type of the building utilisation. 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. 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.
Q iek – sum of internal heat gains in the calculation period Whwhich shall be determined in accordance with Sub-chapter 5. 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 lbb calculated 0033-01 separate zones.
Such internal heat sources like the number of people and duration of their presence in the building shall be assessed by surveying the building, or obtained from the building owner or manager.
Heat flow from the circulation of water in domestic hot water supply systems shall be determined by using the following formula:. Climatic data shall be determined according to LBN “Construction Climatology”, using statistical data of meteorological information. The average temperature of a ventilated 0033-01 shall be assessed when the exhaust fan is switched on.
Q dz,ve – 0003-01 heat losses for cooling through ventilation Whwhich shall be determined in accordance with Sub-chapter 5. Combined measures must be calculated taking into consideration the correlation thereof. If a burner runs with a fixed output without modulation and is equipped lgn a burning time meter, consumption of the fuel shall be the difference between two readings that have been performed at the beginning and at the end of the assessment period, multiplied by the flow speed in the burner.
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:.
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. Floor 00-01 located within the boundaries of the building shall be a conditioned floor calculation area of the lvn A apr.
The following formula shall be used for determining the set-point temperature for heating in one zone calculation:.
System losses within the system boundaries shall be calculated in detail, while outside the system boundaries they shall be calculated by using conversion coefficients. Energy consumption for heating, cooling, heat transmission losses and heat losses through ventilation shall be assessed in accordance with Chapters III, IV, V and VI of this Regulation, taking into consideration internal and solar heat gains and recoverable losses of the technical building system. F l – shading correction coefficient 003-01 the influence of the window position in accordance with Table 2 of Annex 6 to this Regulation.
Q apk,pr – total heat losses for heating through transmission Whwhich shall be determined in accordance with Sub-chapter 5.
Generation of a Test Reference Year for Alūksne, Latvia
Conditions for Calculating Solar Heat Gains. Q dz,n – energy required for cooling, taking into consideration “holiday” periods Wh. Useful area per person m 2. 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.
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.
Generation of a test reference year for Alūksne, Latvia
003-1 heating is irregular or switched off, the influence of the building thermal inertia shall be taken into consideration separately. 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. 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.
Provisions for an Operating Mode of Internal Spaces. If an assessment period is not the full number of years, the annual energy consumption shall be obtained lbh using the extrapolation method.

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. Only energy delivered by solar energy installations and auxiliary energy, which is required for heat delivery to a building from an energy source, shall be taken into consideration in the energy balance.
This Sub-paragraph shall also be applicable to cooling systems Llbn dz,n, iQ dz,sist, i and Q dz,sist,pap, i. If an assessment period is shorter than five years, an adjustment of the energy consumption due to climatic conditions shall be performed.
Q sol – sum of solar heat gains in the calculation period Whwhich shall be determined in accordance with Sub-chapter 5. Q dz,z – total heat losses for cooling Whwhich shall be determined in accordance 003-10 Paragraph 83 of this Regulation.
