Replacement of Decentralized Electric Heating by Air Conditioning Units in Residential Buildings
The goal is to estimate the electricity savings triggered by the renovation of a fixed resistance heating (electric heating) in residential buildings by replacing it with fixed reversible split or multi-split air conditioning units.

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
Efficiency class
-
A++ or better
Building category
Residential, single-family house
Altitude above sea level
1,200 m or lower
Building envelope
Energy efficiency class D or better
Thermal protection
The solar-shading requirements according to SIA 180 (2014) must be met.
Implementation
The replacement and commissioning of the new system must be carried out by a qualified specialist or company.
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.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)

Calculation Formulas
Cumulative Electricity Savings
ΔEeco = (Eold - Enew) × feco × Ns
The cumulative electricity savings result from the difference between the electricity consumption of the old and new state, multiplied by the reduction factor and the standard effective duration.
The annual electricity consumption depends on the annual heat demand of the apartments in the residential building and the utilization rate of the heat generator.
