Use Cases
EED Regulatory Compliance
Avoid EED fines and last-minute compliance scrambles. Automated sub-metering and consumption reporting across multi-tenant buildings - always audit-ready, always on time.
Heat Cost Allocation
End tenant billing disputes with transparent data. Collect heat meter and allocator readings automatically for fair, consumption-based billing that everyone can verify.
Water & Gas Sub-Metering
Catch leaks before they become expensive. Unit-level water and gas monitoring detects abnormal consumption early - reducing waste and enabling accurate per-tenant billing.
Building Portfolio Management
One platform for every building in your portfolio. Deploy across dozens of properties to create unified utility dashboards - eliminating manual reads and giving facility teams real-time control.
