1. Hire and use energy-efficient audio/video/lighting systems.
BENEFITS EXAMPLE
2. Carry out an energy diagnosis to accurately analyse and forecast energy demand: the diagnosis allows energy production to be adjusted to the actual demand, enabling energy consumption to be reduced.
BENEFITS EXAMPLE
3. Set a maximum Sound Pressure Level according to the type of concert to be held and clearly communicate this to the sound engineer.
4. Adopt a 'peak energy demand' saving system, through a battery system installed in line with the power grid to avoid installing additional capacity.
5. Turn off all lights, equipment and heating/air conditioning in every area of the venue (including dressing rooms, bars, etc) when not in use or when not needed or set the automatic timer for this equipment according to your actual needs/use.
6. Turn off all stage equipment after sound-check or when not in use.
7. Choose energy suppliers that provide energy from 100% renewable energy sources.
BENEFITS EXAMPLE
8. Adopt LED lighting (projectors, lights and lamps).
BENEFITS EXAMPLE
9. Invest in renewable energy sources or permanent solar installations on your premises/site.
10. Work with the local community to provide energy to the city or local area during the rest of the year.
11. Communicate the energy efficiency choices of your audio/video/lighting systems to the public.
An environmentally friendly audio/video system saves 10kWh per event compared to the 30kWh consumed in the case of a standard event and thus saves the emission, according to the European energy mix, of 2.13kg of CO2 compared to the total emission of 7.1kg of CO2 of the standard event.
Carrying out an energy diagnosis saves, for a concert, around 10% energy, i.e., around 0.5kg of CO2.
Choosing to purchase electricity from suppliers who only use renewable energy sources saves, for a concert for 400 people, around 4.97kg of CO2.
The estimated annual consumption for three rooms, used for the organisation of an event, with 500 hours of lighting each is 1,500kW, which is less than half that of an energy-saving light bulb, which consumes 3,450kW instead. Translated into percentages, the energy savings from the use of LED bulbs is close to 95% compared to incandescent bulbs, 85% compared to halogen bulbs and 60% compared to fluorescent bulbs.
