More technology, more obligations, the same staff.
PV, heat pumps, tenant electricity, the German GGV: technology and operation are getting more complex. At the same time regulatory requirements are rising along with the expectation of an affordable and climate-friendly supply. The installations are spread across the portfolio. Technical staff is rarely on site and consumption data sits with installers, metering service providers and in manufacturer portals.
How are the installations in your portfolio actually running?
Problems and challenges
Rising technical complexity
New technologies are added without old ones being retired. Heating, PV, batteries and tenant electricity are hard to manage across the board.
Rising service charges burden tenants and owners
Gas and heat prices remain high — every kilowatt hour has to be used efficiently. Service charges rise and their share of the total rent grows.
High investment pressure on a limited budget
New plant technology and building refurbishment are expensive — and compete with ongoing maintenance costs. Existing installations often keep running inefficiently because the funds for a complete renewal are missing.
Only those who know their portfolio can improve it.
Many operators do not know exactly how their heating systems actually run. sektoreins creates transparency about consumption, runtimes and weak points — the basis for decarbonising step by step.
Solutions that really help managers & owners
Reduce heating costs — without construction work
Up to 20 % heating cost savings are possible through consistent monitoring and optimisation of heating curves and cycling behaviour, entirely without rebuilding. sektoreins detects irregularities, missing night setback or poor storage behaviour and readjusts automatically. This works for gas heating just as well as for district heating.
Manage the portfolio — one platform, all properties
Anyone operating 10, 20 or 50 properties needs more than gut feeling. sektoreins gives every responsible person their own access with exactly the views and roles they need — alarms, status and consumption of all sites at a glance.
Use PV power yourself instead of feeding it in
Feeding into the grid is economically unattractive. sektoreins directs PV surpluses to the consumers that currently have capacity: heat pump, buffer storage or battery — maximising self-consumption across the portfolio.
Energy management with tenant electricity or shared supply
Whether physical or virtual summation meter, tenant electricity or shared building supply — sektoreins measures and allocates solar power cleanly per metering point. Even with adjusted grid fees under §14a EnWG, sektoreins manages controllable consumption devices and distributes solar power efficiently.
Make progress visible — for your tenants
Have you already invested in technology or in digitalising your heat generation? Then communicate that progress to your tenants. sektoreins gives every tenant their own access to view heat and, if applicable, electricity consumption transparently. With tenant electricity or shared supply, current PV output and generation forecasts can be shown as well.
Plant operation that thinks ahead
Every installation is different — and no situation stays the same. sektoreins maps your devices as digital twins: they learn how your installation reacts to outside temperature, load fluctuations and changing energy prices. On that basis forecasts for heat load, generation and demand emerge — hours in advance. From these sektoreins derives operating schedules automatically: when does the CHP unit run? When is the storage pre-charged? Even complex situations with several generators, dynamic tariffs and variable loads are handled in a structured way — without anyone having to intervene.
Our results are measurable
energy cost savings
by connecting PV system, heat pump and buffer storage in an apartment building
less gas consumption
through optimised use of PV surpluses and adjusted boiler operation
transparency
through seamless control of heat supply and distribution across the entire portfolio
Voices from the field
„Together with sektoreins we used the solar power in an apartment building optimally for the heat pump, the battery and the heat stores, which reduced the service charges for all tenants considerably.“

there are two ways to put sektoreins to work for your installations, depending on whether a central control system already exists or not.

Wie ein digitaler Zwilling das Verhalten einer Anlage abbildet
Prognosen sagen, was von außen auf eine Anlage zukommt. Ein digitaler Zwilling liest diese Prognosen und sagt vorher, wie sich die Anlage im thermischen und elektrischen Bereich darauf verhält. Dieser Beitrag zeigt, wofür sektoreins ihn einsetzt und wie er entsteht.

5. Oktober 2026Frequently asked questions
On request, tenants receive their own restricted account through which they can view their personal consumption — nothing more. Administrative rights and sensitive plant data remain entirely with the operator.
Tenant electricity and shared building supply require a specific electrical metering concept. Because that metering concept can be integrated into sektoreins, it is also possible to align and control plant operation accordingly.
There is no blanket answer to this question. The savings depend on the existing technology, the building envelope and user behaviour. The potential also depends on how much effort the operator or installer has invested so far in careful commissioning and adjustment. In practice we have observed savings of 10–30 % at our reference customers from optimising the heating system.
Accounts can be created, deactivated or reassigned at any time, with no technical effort. The consumption data is retained and can be used for the final bill.
