During the start-up phase, management focused in particular on establishing processes and the organisational structure. We were able to rely on iteratec’s experience to set up a suitable system architecture for our web-based service. We have now taken over the operation and further development of the platform ourselves with our own developers. The transition went smoothly and without a hitch. We are grateful to iteratec for their professional support during this phase and for laying this important foundation on our path to growth and success.
QIVALO – REAL-TIME CONSUMPTION DATA

- Qivalo | Consumption information in real time
A dashboard for the property management of the future
Measuring and billing heating, water and electricity for individual residential units on a consumption-based basis entails a huge administrative and financial burden for property owners and managers. That is why Qivalo, in collaboration with iteratec, has developed the first digital multi-metering platform for the fully automated recording and billing of these utility consumption figures.
For the first time, property owners, managers and tenants can view consumption figures in real time at any time using the Qivalo Cockpit. The Cockpit, developed by Qivalo and iteratec, remains one of the most technologically advanced platforms on the market today. Not only does it drastically reduce the administrative burden of managing a property, but it also provides the basis for the energy-efficient optimisation of properties. After just six years, Qivalo has successfully established itself in a market with high barriers to entry.
Automated billing thanks to an intelligent data infrastructure
In Germany, consumption of heating, water and electricity must be billed on a usage-based basis for all tenants, even in multi-occupancy properties. The market for so-called sub-metering – that is, the recording of consumption and allocation of costs for heating bills – is estimated at around 1.5 billion euros per year and is dominated by a small number of specialist metering service providers. It is in this market environment that Qivalo has entered the fray to challenge the business model of traditional players by offering automated recording, visualisation and billing of consumption data in properties:
The Qivalo Cockpit offers an intuitive, web-based platform through which property owners and managers, for the first time, have access at any time to real-time data from all main and flat meters, as well as utilities relating to the property – from heat cost allocators and water meters to electricity meters and sensors such as smoke detectors. Based on this data, Qivalo lays the groundwork for the automated generation of consumption-based bills in accordance with the Heating Costs Regulation (HKVO).
Data foundation for the digital energy transition in buildings
At the same time, energy consumption analyses and comparisons between residential units and properties provide the basis for energy-efficient optimisation of the properties, e.g. through climate-adjusted consumption analyses, peak load analyses for electricity or gas consumption, or the benchmarking of different properties within a portfolio. Tenants, too, have the opportunity to optimise their consumption behaviour by gaining insight into their current consumption data.
End-to-end project support
As the exclusive technology partner, iteratec supported the development of the Qivalo Cockpit throughout all project phases – from the initial architectural design, through the design and implementation of the portal and its functionalities, to ongoing operation and the handover of the live system to the client. The solution essentially comprises two components:
- In the property portal – the Cockpit – the meter readings from the smart meter gateway are combined with the property master data and processed further to provide property owners, managers and tenants with near-real-time consumption information at the appliance, residential unit or property level.
- In a separate installation portal, installers can access up-to-date information on the status of the meters in the respective property.

A scalable platform for growing requirements
Key challenges during development included the large volume of data, the scalability of the application and ensuring a high level of data security.
In order to be able to provide the required analyses for the millions of measurement values in the system whilst also taking into account retrospective changes to the data set, all calculations had to be carried out anew on a daily basis. To ensure that consumption information was still provided in near real time, the project team opted for a modular architecture and parallel data processing.
At the same time, the system should be sufficiently scalable to accommodate even larger properties with an increasing number of units and devices.
The portal also had to ensure a high level of data security. This involves, on the one hand, compliance with European and German data protection standards. In this regard, care was taken to ensure that the data was hosted exclusively in Germany. Furthermore, any manipulation of consumption data was to be prevented. To this end, the project team implemented an automatic plausibility check, which enables significant data discrepancies or other anomalies to be automatically reported and investigated.
From start-up to digital champion in property management
iteratec has accompanied the company from the very beginning on its journey from start-up to digital champion in property management – and has provided support that extends beyond technological issues. For example, even before the company was founded, a solution architect helped to design and evaluate the technical aspects of the business idea.
During the development process, the use of agile development methods was essential for achieving a short time-to-market and ensuring the application could be flexibly adapted to changing customer requirements.

By combining metering and sub-metering within a smart meter gateway-based platform, Qivalo creates a fully managed system for the automated collection of data from all main and flat meters across all utilities within the property. An open-system, wireless infrastructure enables building operators and managers to achieve complete transparency regarding consumption figures and processes. Building on this digital infrastructure, Qivalo enables users to easily self-bill their consumption figures, thereby replacing the traditional metering service. It also lays the foundation for all future energy efficiency initiatives and further data-driven optimisations.
The joint venture combines MVV’s expertise and experience in the energy sector and energy technology with the real estate expertise of the Rhein-Neckar property group, enabling them to act as a strong partner for the property sector.
