<p>The forecast control for the heating system tries to maintain the buildings’ indoor</p><p>temperature at a desired level, by using technical building characteristics, data on its</p><p>mode of operation, data on the building location and meteorological parameters. By</p><p>forecasting the conditions of the building and calculating the free energies (solar radiation</p><p>and internal heat generation) it is possible to know the amount of additional heat that</p><p>should be supplied to the building every moment, avoiding heat surpluses or deficits.</p><p>By applying the theory developed by Roger Taesler to buildings 92911 and</p><p>92917 placed in Sandvik AB, it is seen that if the desired temperature was 21ºC it would</p><p>be possible to save a 16.3% of energy, 15518 SEK/year, and that the payback time for the</p><p>installation of such a system is 3 years.</p><p>Other efficiency measures as changing the ventilation schedule or installing a</p><p>heat exchanger are also discussed in the present report.</p>
