Influence of forecast control of heat supply on energy savings

Nowadays, the use of new control techniques of heating systems in existing and new buildings is a very important topic in the light of planed decarbonization of building sector, since the energy efficiency may be significantly increased. One of such solutions may be the forecast control of heat supply for heating, especially if it is easy applicable in existing buildings. This paper shows the influence of forecast control of heat supply for heating on the level of energy consumption based on field research. The building being the subject of case study is a residential building with a traditional heating installation (with vertical risers and convective radiators supplied from one side with the heating medium 80/60°C at outdoor temperature equal to −20°C. The field research covers the period before and after the installation of the forecast control of heating system. The energy savings achieved due to the use of forecast control were above 50%.
