What is Auxillary energy used for?
This is energy used by the HVAC system pumps, fans and controls. Fan coil units are defined as including central ventilation to the space, which Specific Fan Power (SPF) and flow rate should I enter for this system? The auxiliary energy figures for this system include an allowance for the fans in the fan coil units, (and there is a minimum acceptable performance figure in the HVAC guide – 0.8 based on the average of all fan coils). The SFP that users input should be just for the central plant – the fan coil allowance will be included automatically. Similarly, the flow rate should be for the central plant. What enhanced management features are needed in order to claim the ajustment factor offered in table 3 of ADL2A?The adjustment factor is available for “automatic monitoring and targeting with alarms for out of range values”. This means:a complete installation that measures, records, transmits, analyses, reports and communicates meaningful energy management information. It would normal
