Replacement of Commercial Laundry Equipment
The goal of this document is to estimate the electricity savings triggered by the replacement of commercial laundry drying equipment (tumble dryers or drying cabinets) with energy-efficient models on a flat-rate basis.

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.
| Energy efficiency | The new tumble dryers must not exceed the following electricity consumption values determined according to EN 50594:2018. The new drying cabinets must have a heat pump. |
|---|---|
| Tumble dryers with a load capacity of up to 9 kg laundry | |
| Tumble dryers with a load capacity of 10 - 23 kg laundry | |
| Tumble dryers with a load capacity of 24 - 40 kg laundry | |
| Drying cabinets |
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.

Calculation basics: symbols, units and formulasNot needed for the review, useful for recalculating
Symbols, Terms and Units
| Symbol | Description | Unit |
|---|---|---|
e | specific electricity consumption | kWh/kg |
E | annual electricity consumption | kWh/a |
ΔEeco | cumulative electricity savings | kWh |
f | Reduction factor | — |
nw | Usage intensity | kg/a |
Ns | Standard effective duration | a |
Calculation Formulas
Creditable Electricity Savings
ΔEeco = (Eold - Enew) × feco × Ns
The creditable electricity savings result from the difference between the current and new annual electricity consumption, multiplied by the reduction factor (0.75) and the standard effective duration (15 years).
Annual Electricity Consumption
Ex,i = ex,i × nw
The annual electricity consumption is calculated from the product of the specific electricity consumption and the usage intensity (kg of dried laundry per year).

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.
