Central Heating Energy Saving Strategies for a Public Building

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 1196)


The paper addresses the problem of saving central heating energy in public buildings. Public buildings operate only on business days during working hours and only at this time it is necessary to guarantee thermal comfort inside the rooms. Outside of business hours, the room temperature can be reduced resulting in a reduction of the heat energy consumed by the building. The article presents two strategies for reducing the energy consumption: globally lowering the supply temperature of central heating system and locally decreasing the room temperatures. The results of real experiments are presented together with estimates of how the described strategies affect energy saving. Depending on the required operating conditions of the building, the results of the experiments show the possibility of daily savings from 1 GJ to 5 GJ of energy. During the 22 days of experiments, the estimated energy savings were about 17% of the total energy supplied to the building.
