Commercial Real Estate
KNX Smart Office Retrofit
Commercial office building — Berlin Mitte (8 floors)
Challenge
Lighting and HVAC systems on separate unconnected platforms with no occupancy-based control. Annual energy bill of €140,000. Building failing GEG 2024 threshold requirements, facing potential fines.
Solution
Full KNX retrofit across all 8 floors covering 320 presence detectors, motorised blinds tied to sun position, and demand-controlled ventilation integrated with the existing HVAC via BACnet. Central facility management dashboard for the building manager with live consumption and alarm routing.
Impact
Energy consumption reduced 28% — €39,200/year savings. GEG compliance achieved. Payback period 3.8 years.
Residential Property
Smart Metering & Tenant Billing
Residential complex — 180 units, Berlin
Challenge
Manual sub-metering process requiring 3 staff-weeks per quarter for utility cost allocation. Persistent tenant disputes over inaccurate readings. Old billing system non-compliant with current DSGVO requirements for data handling.
Solution
Installed M-Bus smart meters across all 180 units with automated consumption calculation, DSGVO-compliant data handling, and a tenant portal for real-time usage visibility. Automated PDF invoice generation and GEG-mandated consumption reporting.
Impact
Quarterly billing reduced from 3 staff-weeks to 4 hours. Zero billing disputes in year one. Full GEG and DSGVO compliance.
Berlin property owners
GEG 2024 is not optional.
Older Berlin buildings face increasing pressure on energy efficiency thresholds, smart metering mandates, and heating system upgrade requirements. Non-compliance carries real financial risk. We've helped Berlin property owners achieve GEG compliance while generating measurable energy savings — not just paperwork.
