The energy, exergy, thermoeconomic and sustainability analyses are applied to the building heating system with a natural gas–fired combi–boiler. The building area is considered as 90 m². Furthermore, the design and analysis of the natural gas installation of the building are done. Two different methodologies (Fine–HVAC and LowEx analyses) are used for energy analyses (heat loss and demand) of the building. As a result, the energy efficiency of the building is found to be 29.451% using LowEx method. The exergy efficiency of the building is also calculated as 2.906%. The general energy and exergy efficiencies of the combi–boiler are determined to be 94.223% and 12.573%, respectively. Furthermore, it is found that the combi–boiler, which is used in the building as a heating system device, is approximately 11% more sustainable than the building, and thermoeconomic analysis is more beneficial when the exergetic rates are considered.
