Large proportions of tenants are still billed using a standardized calculation that determines their heating bills based on the floor surface area of their apartments. This method reduces the incentive to adopt energy conservation measures, as tenants are not billed according to their individual consumer behavior.
Individual Tenant Billing (ITB) has been introduced to tackle this problem but the technology this method employs, Heat Cost Allocators (HCAs), are prone to miscalculating energy estimates. They can’t adapt to everyday conditions that can affect the way a radiator operates such as the presence of obstructions (furniture), poor radiator maintenance (build-up of dirt or debris) or inadequate commissioning, for example.
