Economy of heat energy

The main factors that determine houses heat consumption, is properly adjusted main heating unit, the technical state of buildings and hot water usage habits.

For house heating unit you can adjust and change the temperature of the hot water circulator, power station treatment time and other parameters, thereby reducing the total payments for the consumed thermal energy. Ensure all pipe good insulation.
For house must battened down the hatches, glass attic and basement windows, keep stairs to the room with the swinging double doors and mechanical door closers. Replace damaged windows. Without need do not open windows and doors in the rooms and other shared facilities.
Radiators in flats must be acurately cleaned before heating season. Tight pack windows and the doors, reducing flow of cold air. The room should be ventilated briefly and intensive. If you have set up thermoregulators, you must choose the minimum temperature in each room.

Individual heat interface units in flats

Painful problem in apartment buildings is unequal accounting of flat heat consumption, cost for heat is calculated by flat area. This problem can be solved with switching to more efficient heating system- individual heat interface unit (HIU), enabling you pay only for own consumption and to reduce bill due to energy saving. According to Latvia ministers cabinet law 907 most of old pipes are time-expired. With establishing individual HIU in houses, old pipes must be repaced. The main conditions of individual HIU establishing are possibility store HIU in the stairwell or flat, construction of new pipeline system and the commitment of citizens to cover conversion costs.
You can acquainted with experience of flat HIU in Rēzekne and with Austria firm HERZ prezentation of individual HIU.

Which affects the amount of SIA "Bauskas siltums" invoices

The amount of each individuals month bill depends on the total thermal energy consumption of each particular residential building. The consumption of thermal energy for buildings varies, and consumption in each building is influenced by a number of factors, which can be divided into three groups (1) weather conditions, (2) the technical state of the building and (3) the behaviour of the residents of the building.

1. Weather conditions

Thermal energy consumption is not only influenced by outdoor air temperatures but also by humidity and wind speed. Humidity covers and cools the walls, taking heat from inside, so the thicker the wall, the higher the thermal energy consumption. As shown in the table, the higher the air temperature, the higher the humidity, the more energy is subtracted from the buildings wall for evaporation of water.Thermal energy consumption is not only influenced by outdoor air temperatures but also by humidity and wind speed. Humidity covers and cools the walls, taking heat from inside, so the thicker the wall, the higher the thermal energy consumption. As shown in the table, the higher the air temperature, the higher the humidity, the more energy is subtracted from the buildings wall for evaporation of water :

Temperature Maximum air saturation g/m3
-20 1.05
-10 2.31
0 4.69
+5 6.82

Evaporating water from the walls while blowing the wind, reinforces the consumption of thermal energy. The higher the wind speed, the higher the thermal energy consumption. Consequently, the energy difference, which comes as savings from higher outdoor air temperatures, the increase in thermal energy consumption due to humidity and wind is "eaten". The table shows the "temperature of feelings" in degrees that describe the feeling of human warmth as a result of wind exposure:

Outdoor air temperature wind 5 m/s wind 10 m/s wind 15 m/s
+10 +8 +6 +5
+5 +1 0 -2
0 -5 -7 -8
-5 -11 -14 -15
-10 -17 -20 -22

2. Technical condition of the building

Most of the apartment buildings in Bauska have been built in the 70s of the last century and the buildings are half a century old. Internal communications of buildings are also, in most cases, just as old, like the buildings themselves, or for at least a few decades. law of Apartment Property states that only and exclusively apartment owners be responsible for the technical state of internal communications. Unfortunately, experience shows, that apartment owners are particularly in no rush with the replacement of internal communications against today demands. In those multi-apartment buildings the apartment owners of which have undergone renovation work, significant reduction in thermal energy consumption, compared with buildings that apartment owners dont.

3. The behaviour of the residents of the building.

The behaviour of the population itself has a significant impact on thermal energy consumption. Open windows, open doors, contrary to the view of the population, nevertheless affect the consumption of heat. Energy efficiency professionals recommend that windows, doors be sealed during the heating season in order to minimise heat leaks as well as fanning the rooms intensively but briefly. It is also recommended that doors and windows, basement windows and the like should not be opened without need. The inhabitants of the building must agree between themselves on the optimal air temperature in residential areas. The housekeeper should be informed of this in order not to create situations where apartment owners have lasted there are open windows, because the rooms are too hot, thus wasting thermal energy. If the air temperature is too high for the majority of the population, the housekeeper should be informed. Reducing air temperatures by up to 1 degrees can lead to significant heat savings for the entire building. It is also worth remembering that the behaviour of each resident in his individual apartment is affecting the total thermal energy consumption of the building. For example, if someone plans to change the windows in the apartment during the heating season, bills will rise for all apartments in the building as the total heat consumption of the building increases.
