Gama Aviation Ltd have two large heating units in their main engineering hangar at Farnborough Airport, which would run continuously throughout the day but never reach the thermostat set point of 14°C.
Following installation of the Airius system their HVAC system would achieve the thermostat set point with only one of the two heating units running. Once at the temperature set point the Airius system would then maintain the desired conditions with only the one remaining heating unit running intermittently.
In September and October of 2012 (PRE AIRIUS) the heating gas consumption was 2,356m³. In September and October of 2013 (POST AIRIUS) the heating gas consumption was 1,042.3m³.
If the weather was consistent each year then this would have shown a 55.76% saving. In reality the mean average temperatures based on figures provided by the MET Office were as follows:
September – 2012 13.4°C 2013 13.9°C
October – 2012 10.1°C 2013 12.7°C
