The forecast control for the heating system tries to maintain the buildings’ indoortemperature at a desired level, by using technical building characteristics, data on itsmode of operation, data on the building location and meteorological parameters. Byforecasting the conditions of the building and calculating the free energies (solar radiationand internal heat generation) it is possible to know the amount of additional heat thatshould be supplied to the building every moment, avoiding heat surpluses or deficits.By applying the theory developed by Roger Taesler to buildings 92911 and92917 placed in Sandvik AB, it is seen that if the desired temperature was 21ºC it wouldbe possible to save a 16.3% of energy, 15518 SEK/year, and that the payback time for theinstallation of such a system is 3 years.Other efficiency measures as changing th...
