Replacement of Lighting Systems for Tennis and/or Football Fields
The goal is to standardize the calculation of electricity savings triggered by the replacement of lighting systems for tennis and/or football fields, taking into account all consumption-relevant parameters such as illuminance, field size and usage profile.
Requirements
Only measures that meet the requirements of the Energy Ordinance (SR 730.01; EnV) can be credited. The additional requirements for the technical characteristics and for the implementation of the measure are set out in Table 1.
| Old system | New system | |
|---|---|---|
| Quality verification | - | Illuminance of the new installation no more than 20% above the standard value from SN EN 12193:2019 Table A.16 (tennis) and A.21 (football) Compliance with SN EN 12193:2019 as well as SLG301:2020, SLG302:2021, SLG306:2021. |
| Old / New system | ||
| Implementation | Planning, installation and commissioning of the new system must be carried out by a qualified specialist / company and metrologically verified after completion. | |
| Disposal | The consumption-relevant components of the old devices may not continue to be operated within Switzerland. Proper disposal or export must be demonstrable on request. | |
Proof of compliance
Compliance with the requirements must be demonstrated by the following documents. The documents listed in Table 2 are an integral part of the proof of measure implementation.
- 1.Invoice documents (PDF, PNG or JPEG format)
- 2.Explanation (PDF format, max. 2 A4 pages) of how it is ensured that the replaced devices were properly disposed of (e.g. by means of declarations, disposal items on contractor invoices, etc.).
- 3.A metrological report (PDF format) documenting the correct illuminance levels after commissioning.
- 4.Information on the new installation (project description with luminaire and control specifications).

Symbols, Terms and Units
| Symbol | Description | Unit |
|---|---|---|
E | annual electricity consumption | kWh/a |
ΔEeco | cumulative electricity savings | kWh |

APlatz | playing field area | m² |

Ns | standard effective duration | a |
Calculation Formulas
Annual Electricity Consumption Sports Field Lighting
The annual electricity consumption results from the total installed power multiplied by the annual usage hours.
Installed Power
The required installed power results from the required illuminance multiplied by the playing field area, divided by the system efficiency.
Annual Electricity Savings
The annual electricity savings result from the difference between electricity consumption before and after the measure.
Cumulative Electricity Savings
The cumulative electricity savings result from the annual savings multiplied by the standard effective duration and the correction factor.

Part of the EFFEL programme
Standardised measures are one of two measure types in the EFFEL programme (efficiency improvements by electricity suppliers, Art. 46b EnG). They follow a predefined SFOE catalogue with fixed savings values.
