EE MUSIC partner TerraSystemics undertook an energy audit of a club in Lisbon in 2015. To allow greater sharing of data, the findings are presented anonymously.

Key Data

Club B

Area

250 m2

Maximum capacity

100 people

Type of construction

Old building, downtown Lisbon

Energy consumption type

Only electricity

Annual electricity consumption

50 000 kWh

Contracted Power

 27.6 kVA

Key inefficiencies found: 

  • Low energy efficiency of some of the existing refrigeration equipment.
  • There is a potential for energy savings on the replacement of lighting fixtures, and dishwasher machine.
  • The club doesn’t have monitoring systems or energy consumption control or energy management routines.
  • This was the first energy audit of the club. 

Key best practice found:

  • Management team has a good level of awareness about the importance of energy efficiency in the management of their club;
  • Some lighting improving measures were already taken before this energy audit, such as, motion sensors have been installed in the stairs, LED lamps on the back bar and placement of energy-saving lamps in some areas.

Key data highlights:

The main energy-consumer systems are:

  • Kitchen equipment (47%);
  • Lighting and sound equipment (28%);
  • Refrigeration equipment (22%);
  • Ventilation and heating (3%).

The EE MUSIC IG Tools were used to get an automatic comparison to existing benchmarks. The following is a screenshot from the EE MUSIC IG Tools: 

 

Key Recommendations: 

  • It is recommend to replace the refrigeration equipment by other more energy efficient, equivalent to class energy A+++, as far as it is reasonably practicable.
  • Analyse with the energy supplier to increase the Contracted Power, which should be around 50% higher than the actual power consumed during the year.
  • It is recommended to use this good practice: refrigeration equipment (freezers, ice machines, etc.) with a minimum of 30 cm distance between the device and walls or surrounding objects.
  • Training awareness campaigns about energy efficiency to the staff of the clubs.
  • Ensure regular maintenance of refrigeration equipment, including filter and air vents cleaning.

Proposed measures with energy savings potential: 

  • Lighting fixtures: replacement of existing energy inefficient lamps by LED technology leads to 6700 kWh of energy savings and approximately 1000 € of saving costs per year. This measure has a payback of less than 1 year (investment of 715€ in LED lamps).
  • Kitchen area: replacement of the current dishwasher by other more energy efficient, equivalent energy class A+++, leads to 4 320 kWh of energy savings per year, and approximately 770 € of saving costs per year. The necessary investment is around 1 400 €, which turns in a payback of less than 2 years.
  • Organisational/behavioural measures: key recommendations suggested on the next table leads to 4 390 kWh of energy savings per year, and 660 € of savings cost per year, with a low investment of 1 000€.
  • In sum, the measures identified have a potential of around 15 400 kWh of energy saving per year, and 2 430 € of energy saving per year, with an average payback of 1.3 years.

This energy saving potential corresponds to:

  • 29% annual energy savings of kWh;
  • 3.62 tCO2e savings per year;
  • 25% annual costs savings of electricity bills.
