Legal Framework
The Building Energy Act (GEG) requires landlords to maintain energy efficiency minimum standards. Particularly relevant: heating boilers older than 30 years must be replaced (§ 72 GEG). Insulation requirements for roofs and pipelines also apply.
Utilizing Funding Programs
Many private landlords shy away from investments, despite available government funding. KfW grants or BAFA subsidies significantly reduce costs. A landlord in Mainz financed 30% of his facade insulation through funding programs.
Cost Allocation
Modernization costs can be partially passed on to rent (§ 559 BGB). Proper calculation and notification are essential.
📌 Legal Precedent
BGH, VIII ZR 80/06: Allocation of modernization costs is permissible if notification periods are observed.
💡 Pro Tip
Always check funding opportunities before renovation and obtain quotes early.
Checklist: Energy Efficiency Obligations
- Check heating boilers older than 30 years
- Control insulation of attic and pipes
- Keep energy certificate current
- Apply for funding opportunities
Conclusion
Energy renovation is mandatory, but also an opportunity: those who modernize increase property value, reduce operating costs, and prevent rising CO₂ charges.
