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 A

Area

180 m2

Maximum capacity

280 people

Type of construction

Old building, downtown Lisbon

Energy consumption type

Only electricity

Annual electricity consumption

54 000 kWh

Contracted Power

 41.4 kVa                                                                   

Key inefficiencies found:

  • Low energy efficiency of some of the existing refrigeration and air conditioning equipment.
  • There is a potential for energy savings on the lighting fixtures; fan and air conditioning, and cooling system.
  • The club doesn’t have monitoring systems or energy consumption control or energy management routines.
  • This was the first energy audit of the club.
  • Power surges.

Key best practice found:

  • Management team has a good level of awareness about the importance of energy efficiency in the management of their club;
  • Management team has willingness to learn more information and to start implementing best practices and improving the energy efficiency of the Club.

Key data highlights:

The main energy-consuming systems are:

  • Kitchen refrigeration machines (46%);
  • Ventilation and air conditioning (30%);
  • Stage lighting and sound equipment (17%);
  • Total lighting, except stage (5%);
  • Compressed air (2%).

 

 

The EE MUSIC IG Tools were used to get a year-to-year comparison of the energy consumption, as well as an automatic comparison to existing benchmarks. The following are screenshots from the EE MUSIC IG Tools:

Key Recommendations:

  • Prevent power surges, and avoid the possibility of tripping of circuit breakers: it is advisable to connect the air-conditioning equipment first, wait 3 to 5 minutes and then connect the remaining equipment since the air conditioning equipment starting demand is 2 to 3 times higher than its normal operating electrical demand.
  • It is recommended to clean the tubular fluorescent luminaires in order to obtain better efficacy of its luminous flux.
  • 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 metal halide lamps by LED technology leads to 750 kWh of energy savings and approximately around 150 € of saving costs per year. This measure has a payback of 3 years.
  • Fan and air conditioning: replacement of the current air-conditioning engine by another more efficient one (with Coefficient of Performance ≥ 2.5), this leads to around 4 850 kWh of energy savings and approximately around 750 € of saving costs per year, with a payback of 6 years.
  • Cooling systems: replacement of 2 old cooling machines by other more efficient ones, with energy class A+++, leads to around 2 100 kWh of energy savings and approximately around 350 € of saving costs per year. This measure has a payback of 3 years.
  • Organisational/behavioural measures: key recommendations suggested on the next table leads to 6 860 kWh of energy savings per year, and 1030 € of savings cost per year, with a low investment of 1 000€.
  • In sum, the measures identified have a potential of around 14 560 kWh of energy saving per year, and 2 180 € of energy saving per year, with an average payback of 3 years.

This energy saving potential corresponds to: 

  • 23% annual energy savings of kWh;
  • 3.42 tCO2e savings per year;
  • 22% annual costs savings of electricity bills.
