building constructions absorb the temperature wave caused temperature
fluctuations of external air. It means this building construction has a
thermal stability. Therefore, there is a reserve for warmth
accumulation which can be used for decreasing of thermal losses. The
developed mathematical model of temperature distribution in an
enclosure structure allows estimating the cooling velocity of assorted
designs of enclosure structures. And it shows the time which it is
possible to turn off heating during the non-working period with
maintenance required temperature condition in working period. This
method allows reducing losses of heat energy considerably. It gives the
chance to perform the optimum choice of periodic schedules of heating.
Cost efficiency of implementation of the periodic mode of heating of
the building is proved.
