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 | |
|---|---|---|
| Technology | Fixed electric, electric storage and electric underfloor single-room heaters within the scope of Annex 1.18 EnEV | Fixed reversible split or multi-split air conditioners (maximum 2 outdoor units per building) within the scope of Annex 1.13 EnEV |
| Building category | Residential, single-family house | |
| Implementation | The replacement and commissioning of the new system must be carried out by a qualified specialist or company. | |
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.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.).
- 2.Invoice documents (PDF, PNG or JPEG format)
- 3.GEAK building energy certificates or a brief explanation of the CO₂ calculator input data (PDF format)

ΔEeco | cumulative electricity savings | kWh |
fP | utilization factor | — |
Ns | Standard effective duration | a |
Calculation Formulas
Cumulative Electricity Savings
ΔEeco = (Eold - Enew) × feco × Ns
The cumulative electricity savings result from the difference between the electricity consumption without and with remote control, multiplied by the reduction factor and the standard effective duration.
Annual Electricity Consumption
Ex,i = (fP,i/η_x) × fR × (Qli0 + ΔQli × a) × (1 + (9.4 - θ_e,avg) × 0.06 K⁻¹) × AE
The annual electricity consumption is reduced by the utilization factor, which takes into account the lowering of the room temperature during absence.
