IEA SHC Task 38 Monitoring Procedure Table 11 Summary of the output of the 3 rd monitoring level Third monitoring level Description SHDC DEC Fsav,fossil or Fsav,res Fsav,fossil FSC_SHC ACM_water, y DEC_water, y Water consumption COP_el_chill COP_el_coldSol,y COP_el_cold,y COP_th_chill,y Water_treat, y COP_el_DEC-Sol,y COP_el_DEC,y COP_th_DEC,y Fractional primary energy saving of the monitored system accounting for RES or fossil as it is existing compared with a conventional system For DEC systems 5 different versions are calculated. Fractional primary energy saving of the monitored system accounting RES as fossil compared with a conventional system; (artificial number for comparison reasons) For DEC systems 5 different versions are calculated as described before. Fractional solar consumption of the available solar energy compared to the overall heat load Electricity consumption for water treatment Electrical COP of the chiller Electrical COP of the heat driven cooling system Electrical COP of the heat driven cooling system plus solar collectors Thermal COP of the heat driven cooling system For a visual representation of the results the following kind of graph has been used: 31 99% draft Version
