## Total home consumption

If the apartment building has an uninhabitable fund (an object with its own meter of thermal energy and (or) warm water), the consumption of each part is calculated. The MWh consumed to heat the warm water are calculated by multiplying the standard coefficient 0.0465 MWh/m3 (amount of energy for heating 1 m3 of cold water) with warm water consumption. In the example of a house in Plūdoņa 29, the total consumption is 29.87 MWh, which breaks down for a store of 0.05 MWh for warm water and 4.46 for heating. For apartments in the house, 25.36 MWh is used for further calculation

If there is no separate thermal energy meter for the object of the non-residential fund, then MWh for heating is calculated in proportion to the area.

## Calculation of the heat cost of apartments.

In the calculation of the house, if the apartments do not have allocators or individual thermal energy meters of the apartment, the generally accepted algorithm is applied:

-determine the total fee of the house only for heating warm water and, accordingly, the price for heating 1 m3 of water. The total fee for warm water is divided between apartment properties in proportion to consumption. The remaining part consists of heat losses from the hot water system and heating, which are distributed in proportion to the area of the apartments. Regardless of whether the hot water system in buildings is built with or without circulation, the algorithm is valid in both cases. If the apartments of the house have allocators or individual thermal energy meters, Their readings, respectively, are used in the overall calculation of the house. In the summary of the calculation of an ordinary house, the cost per 1 m3 of warm water is calculated at 4.1394 EUR. Accordingly, each apartment shows the calculated fee for hot water and heat.

In the example of an apartment bill, 2 m3 of warm water consumption multiplies by the set price of 4.1394 EUR. The remainder of the payment consists of the calculated MWh per heating of 0.7799 Mwh once that of the month in question set heat energy tariff 89.02 EUR/MWh. If the house uses direct settlements, then direct settlement services are added, which are subject to a 21% tax.heating, which is distributed in proportion to the area of the apartments. Regardless of whether the hot water system in buildings is built with or without circulation, the algorithm is valid in both cases. If the apartments of the house have allocators or individual thermal energy meters, Their readings, respectively, are used in the overall calculation of the house. In the summary of the calculation of an ordinary house, the cost per 1 m3 of warm water is calculated at 4.1394 EUR. Accordingly, each apartment shows the calculated fee for hot water and heat.

For an apartment with allocators, the algorithm for calculating the charge of selected allocators is carried out. The percentage distribution between allocators and the area can be applied or a fixed fee per unit of allocators. The algorithm for calculating applied allocators is chosen by the inhabitants of the house. The example uses a charge per 1 allocator unit equal to the corresponding month tariff KWh, which is 89.02 EUR/MWH/1000 = 0.0890 EUR/KWh

For apartments with an individual thermal energy meter, their read consumption multiplies by the tariff. In the example of the bill, the heat consumption of an apartment of 0.400 MWh multiplies by the tariff.
