Improve energy efficiency in a
public administration building



Public administration



Catalan Energy Institute (ICAEN)



€34,552 a year (22.5% of the electricity bill)






6.2 months

Objective achieved:

The integrated measurement and control system saved €34,552 on the electricity bill during the first year and ensured better energy monitoring and a more environmentally sustainable building.


As a result of applying all the measures taken, energy consumption was reduced by 20% in the period 2012-2013, with total savings on the annual electricity bill of 22.5% (€34,552) in 2013. 

As a result of the implementation of the management system and application of corrective measures the following results were achieved:

  • ––Inefficient consumption detected and corrective measures applied.
  • ––Savings in the measurements taken were recorded.
  • ––Payback on the investments made was calculated.
  • ––Evaluation and continuous improvement criteria applied.
  • ––Maintenance works controlled and improved.

Initial situation

The Department of Business and Employment building is the headquarters for the Ministry of Energy, Mines and Industrial Safety, the Catalan Energy Institute (ICAEN) and the Catalan Consumer Agency. It had an annual energy consumption of 1,535,650 kWh, with an annual energy cost of €153,565, as well as a contracted power cost of €24,300 per year. The managers therefore prioritised improving the energy efficiency of the installations in order to reduce the average monthly energy consumption, which was 127,790 kWh.

The primary energy costs were air conditioning (36%) and lighting (25%). Consumption fluctuated given the normal working hours in the offices, although they were more variable than they should have been. There was no energy consumption forecasting or any comparison with previous months and years. According to the agreement of the Government of Catalonia, in their Energy Efficiency and Savings program of July 2007 and August 2011, to conduct energy audits in all Government buildings and premises with an annual consumption greater than 200,000 kWh, this building logically falls under said program.
