Measures for Decarbonization of Heating System in Large-Hall Buildings with Gas Radiant Heaters

The process of reducing or eliminating carbon dioxide (CO2) emission is a priority in transforming Europe into a climate-neutral continent by 2050. Decreasing the energy use of buildings is a crucial measure to improve their energy performance and reduce emissions associated with heating system. The article gives new insight into certain options to decarbonize the heating installation of large-hall building equipped with the widespread system of gas radiant heaters. Based on a review of technical data of gas radiant heaters and own research some opportunities to improving energy efficiency of the building with regards to the aforementioned heaters were recognized. Action that can be taken include: buildings energy needs lowering, using high-efficiency heating devices, waste heat recovery from flue gases, implementing carbon-free energy carriers like hydrogen, and appropriate building automation and energy management system. Those measures to decrease CO2 emission may be implemented in new as well as in existing hall buildings. Analyses have shown it is possible to reduce CO2 emissions by 5 to 43% and zero CO2 emissions is ensured when fueled by hydrogen.
