Development of a tool based on thermoeconomics for control and diagnosis building thermal facilities

This work develops a software to control and diagnose building thermal facilities based on thermoeconomics. It is tested with the data obtained from three blocks in Basque Country (northern Spain) aim of detecting potential energy saving points mitigating environmental impacts. Some obstacles, solved, are related insufficient number probes inherent errors sensors. Besides, new methodologies for performing thermoeconomic dynamic analysis described. Apart this, inefficiencies components quantified, cost calculation all flows done different operation modes discussed. The outcomes discussed their exergetic, economic average unit calculated. In such way, intervention system analysed lower higher fuel consumption detected. results show that domestic hot water (DHW) production has an value 13.72 c€/kWh heating 12.92 c€/kWh; addition, boilers have 1,587 MWh real losses. operating opens research line thermoeconomics applications. information key fact optimization searching high performance buildings.
