Workswell becomes an auditor for your EffEl files

Swiss electricity suppliers must help their customers save electricity, and several of them pay for the savings achieved. Workswell is becoming an auditor to help you get yours recognised: we identify what can count, measure the result and put the file together for you.

EffEl in brief

EffEl is not a subsidy. Since 2025, electricity suppliers have been required to achieve electricity savings among their customers, and this obligation increases every year. To meet it, they look for real, proven savings, and several of them pay for them.

The amount depends on the saving recognised and on the supplier. We estimate it with you before the works, without promising it.

Our role as auditor

A saving only counts if it is calculated and proven according to the federal rules. That is the auditor’s job. As auditor, Workswell:

• identifies the installations that can count;
• calculates the saving and tells you what it can bring in;
• measures electricity consumption before and after the works;
• gathers the supporting documents and submits the file;
• follows it through to payment.

The contribution is yours. The auditor’s share is agreed with you before submission.

Measuring, understanding and optimising energy in buildings is Workswell’s business. This auditor role stays with Workswell after 1 January 2027, when building automation engineering moves to wall-i.

Which installations

We start with what we know best: ventilation and its controls. Many schools, offices, hotels and public buildings still have two-speed ventilation systems that run for long hours. Fitting them with modern motors, controlled according to actual demand, lowers their consumption.

What can count depends on the installation: what is replaced, its age, how it will be controlled afterwards. We check this case by case, then measure the installation’s electricity consumption before and after the works: that is the proof of the saving.

EC-SWAP and EC-SWAP-PRO

Workswell also develops the Wellset modules EC-SWAP and EC-SWAP-PRO. They replace the two-speed motor of a ventilation system with an EC motor, without redoing the controls. EC-SWAP-PRO, announced for 2027, also adjusts the airflow according to air quality: it is this demand-based control that makes the saving, and that counts for EffEl.

How it works

1. First discussion and site visit. We survey the installations: motors, age, settings, operating hours.
2. Estimate. We tell you what can count, what it can bring in and what needs to be planned. You decide.
3. Measurement before the works. We measure the installation’s electricity consumption before anything is touched: consumption that was not recorded cannot be reconstructed afterwards.
4. Works. Your usual contractor carries them out. We check the settings with them at commissioning.
5. File. We measure consumption after the works, compare it with the consumption before, gather the documents and submit the file.
6. Validation and payment. A supplier takes over the saving, it is validated, and the contribution is paid to you.

Frequently asked questions

How much can it bring in?

It depends on the electricity saved and on the supplier that takes over the saving. We give you an estimate before the works; the final amount is set by the supplier.

Is it only for large companies?

No. Owners, property managers, companies and public authorities can all benefit, anywhere in Switzerland.

Do we have to go through our own electricity supplier?

No. Your supplier may have its own programme, and that is a good route. Other Swiss suppliers can also take over the measure. A saving can only be recognised once, by a single supplier.

We have already received a subsidy for these works. Can the two be combined?

No. A saving that has already been subsidised does not count a second time. It is better to compare the two routes before applying for either.

What happens to the old equipment?

It must no longer be used in Switzerland. Its disposal, or its export, must be provable.

How long does it take?

Measurement generally takes one to two weeks before the works, and as long afterwards. Payment follows once the file has been validated.

What if the measured saving is lower than expected?

Only the proven saving counts. That is why we estimate cautiously before the works, and why we measure before and after.

A ventilation system to renovate?

Send us the list of your air handling units, or simply a photo of their nameplates: we will tell you which measure can apply and what needs to be planned before the works. Contact us
