§ 2



(1) heating period begins 1. September and end on 31 December. in May of the following year.



(2) the supply of heat energy will start/period, when the average

day temperature outdoor air in the appropriate place or location

falls below + 1 ° C in 2 consecutive days and by the development of

the weather can be expected to increase the temperature above + 13 ° C for

the following day.



(3) the average daily temperature of outdoor air is a quarter of the sum of the

the outdoor temperature measured in the shade to the exclusion of the influence of radiation of the surrounding

areas at 7 am, 2 pm and 9 pm, with the temperature measured at 9 pm

h. is counted twice.



(4) Heating of apartments and non-residential premises in the residential and non-residential buildings

restricts or suspends/period when average daily

outside air temperature in the appropriate place or location will

above + 13 ° C in 2 consecutive days and the weather

This temperature can be expected to decline for the next day. Restrictions

heating is done so in order to meet the requirements of their beat-lotního

the attenuation of ensuring the thermal stability of the room. When subsequent

decrease in the daily average outside air temperature below + 13 ° C,

heating resumes.



(5) in the case of the consent of at least two-thirds of the final consumer,

heating takes place outside the heating period, if required by the progress of the

outdoor temperatures and if permitted by the technical and supply conditions.



(6) during the heating period are flats at the time from 6 am to 10 pm. and

other facilities at the time of their operation heated so that the formal

the average temperature of the internal air temperature afforded the calculated

indoor air provided for project building.



(7) the Calculated temperature of internal air provided for the project is resulting

temperature, which takes into account the internal air temperature and the effect of radiation

the surrounding walls. Checking compliance with the calculated temperature of internal air
