| Increase of energy efficiency in existing buildings is one of the first and recommended steps in the process of decarbonising the building stock. In this context, the selection of the most appropriate energy efficient measures should be not only energy effective but also cost effective. That is why, significant efforts and research have been made in the topic of controlling the energy supply to space heating systems. However, there is a noticeable gap of results with detailed analyses supported by field research and by measured data on the adjustment process of the well-known heating curve, which is used by the majority of existing controllers for space heating systems. This paper presents a method for detailed analysis of the process for adjusting the heating curve to real energy needs of a specific heating system. The study utilizes the data collected from a long-term field research at two multifamily buildings located in Poland. The field data was used to analyse two approaches for adjusting the heating curve, one based on calculated energy savings following a building’s energy renovation, and another one based on real energy needs of a building. The analysis and the results were organized into two data sets, corresponding to outdoor temperature below and above 0 °C that represent different operating conditions at peak and partial heating loads. It was found that following the proposed method the adjustment of the heating curve in the analysed buildings resulted in average energy savings ranging from 4 to 15 %. Higher energy savings of about 9–23 % were achieved in periods operating at partial heating load, when the outdoor temperature was above 0 °C. The need for future research and development of control systems for space heating is underlined. |
