EPBD & GEG for Electrical Planners
What the EU Buildings Directive and the German Building Energy Act mean concretely for your construction project — explained clearly, with an obligations check.
As of: 02/05/2026 · Note: GEG / GModG are politically in flux — re-review after Q3 2026.
The EPBD recast (Directive EU 2024/1275) was adopted in May 2024 and must be transposed into German law by 29 May 2026. In parallel, Germany's Building Energy Act (GEG) is being reworked through the GModG reform of the federal government in 2026.
For owners, architects and main contractors, this creates concrete new requirements for electrical planning — from PV connection and charging infrastructure to building automation and energy monitoring. This page shows what is relevant for your project.
Obligations timeline
EPBD ↔ GEG: who regulates what?
The EU sets the framework (EPBD), Germany implements it nationally (GEG / GEIG). Here are the central mappings.
| Topic | EPBD (EU) | GEG / German law |
|---|---|---|
| Solar mandate | Art. 10: PV on non-residential new builds > 250 m² from 31 Dec 2026. | Currently state law (BW, NRW, BY, RP …) + EPBD transposition into GEG expected. |
| Heating / RES | Art. 17: phase-out of fossil boilers by 2040. | GEG §71: 65% renewables obligation (tied to heat planning). GModG reform 2026 in progress. |
| Building automation | Art. 13: BACS for non-residential > 290 kW today, > 70 kW from 2030. | Implementation via GEG amendment 2026 in preparation. |
| Charging infrastructure | Art. 14: stricter charging-point / pre-cabling obligations. | GEIG (Buildings Electric Mobility Infrastructure Act) — amendment by 29 May 2026. |
| Zero-Emission Buildings | Art. 7: public new builds from 2028, all new builds from 2030. | German implementation in preparation — expected with GEG amendment. |
| Minimum standards (existing) | Art. 9: 16% worst non-residential stock by 2030; residential as aggregate path. | National renovation plan pending — publication expected with implementation. |
| Energy performance certificate | Art. 19: harmonised A–G scale EU-wide. | GEG §§ 79–88: existing obligations, alignment to A–G scale in 2026. |
What does this mean for electrical planning?
Low voltage & main distribution
Reserve capacity for heat pumps, PV feed-in and wallboxes must be sized early. §14a EnWG control boxes and FI Type B are part of the new standard.
Building automation & MSR
BACS-compliant MSR concept (BACnet/KNX/Modbus), submetering by energy carrier and user group, open interfaces for energy monitoring and CAFM.
Charging infrastructure
Dynamic load management, transformer reserve for large charging parks, calibrated metering and billing concept (MSB role), conduits even where no charging points are planned yet.
PV & storage
Self-consumption strategy (direct marketing vs. EEG feed-in), sector coupling with heat pumps, storage sizing matched to load profile and funding logic (KfW 270, EEG).
Metering technology
Smart meter gateway (iMSys), submetering for efficiency reporting (BACS), interfaces for energy management systems. Size meter cabinet early.
When do you need an electrical planner for EPBD/GEG topics?
Concrete situations where a kickoff call pays off:
- ▸Before submitting the building application — clean obligations capture in the pre-planning phase saves expensive change orders later.
- ▸When applying for KfW/BAFA funding — funding tier and obligation fulfilment must align (e.g. EH 40 + PV mandate).
- ▸When a GEG proof is due — we deliver the building services data at the required depth.
- ▸When replacing the heating in existing buildings — load reserve, FI Type B, possibly §14a control box planned right away.
- ▸When an iSFP / renovation roadmap is being created — include electrical measures as building blocks.
- ▸For new builds towards 2028/2030 — the Zero-Emission concept affects all trades, lock it in early.
Obligations check: what applies to your project?
Six steps. The result appears immediately, before you enter contact details. Not legal advice — a substantiated technical assessment.
What kind of construction project?
Pick the right type — determines which obligations apply at all.
