Cool response to a heated situation

  • Channelling heat out of the printing plant saves air-conditioning costs
  • Substantial energy savings (9 MWh)
  • 2.9 tonnes less CO2 emissions, saving around € 2 040 a year

Graficas Z is a specialist printer in the Aragón region of northeastern Spain. This innovative SME is constantly looking for opportunities to reduce costs and improve production by introducing energy-saving measures.

One relatively simple measure identified was to link parts of its heating-cooling system to an extractor which channels the heat outside the plant. This alleviates ambient temperature inside the building during the hotter summer months.  

Key results

This conversion saves 9 MWh of electricity and 2.9 tonnes of CO2 emissions emanating from the plant's heat pump. Graficas Z pays around € 2 040 less in annual electricity costs thanks to the heat extraction measure.
