01
Technically sound
Planning, components and implementation based on one coordinated project approach.
02
Practical
Solutions for real technical requirements in projects and operation.
03
Future-proof
Designing infrastructure, buildings and project data for long-term use.
Which solution fits your project?
Whether it’s a district heating network, building energy or a digital project structure: the starting point is your specific technical task – not our internal departments.
District Heating & Infrastructure
Buildings & Energy Technology
Heating load, thermal building simulation, heat pump and PV planning, storage, PV fencing and LED as a technical basis for decision-making.
Digital Solutions
Structuring documents, project data, tasks, monitoring, knowledge, approvals and interfaces so that project information remains usable in day-to-day work.
What is your role in the project?
You don’t need to know which of our service areas is responsible internally. What matters is your starting point: assessing feasibility, planning infrastructure, evaluating energy potential, safeguarding investments or integrating specialist support.

Technical decisions based on a coordinated project approach.
You receive a technical basis for decision-making, suitable system options and a transparent project approach – so the next step can be decided with confidence.
Technically sound
Calculations, simulations and feasibility studies create a transparent basis for decision-making.
The right components
Products and systems are derived from the project’s technical requirements.
Cost-conscious
Options are structured so that the differences become clear.
Digitally supported
Documents, knowledge, monitoring and project data are connected wherever this creates tangible benefits.
Technical experience. Direct responsibility.
RIEGER Energietechnik AG is owner-managed and combines short decision-making paths with hands-on technical expertise.
In its current set-up, the company structures its offering into District Heating & Infrastructure, Buildings & Energy Technology and Digital Solutions.
From technical project business to connected system thinking.
The former Rieger Energietechnik has been transferred into Rieger Energietechnik AG. Today, the company combines engineering, components, technical project support and digital structuring.
Technically sound. Economically transparent. Future-oriented.
Our mission and vision set the direction for project work and further development.
Preparing technical decisions on a reliable basis.
We create a technically sound basis for decision-making, select suitable components and structure projects so that energy infrastructure and building solutions can be implemented reliably, economically and transparently.
Engineering at the core of a more connected B2B platform.
RIEGER is evolving towards a digitally connected B2B platform for technical energy infrastructure, building energy technology and project-specific system solutions. This vision describes a strategic direction – not a market position that has already been achieved.
From the initial situation to the right system solution.
The process reduces unnecessary iterations and keeps technical decisions transparent.
Understand
Clarify objectives, initial situation, requirements and scope boundaries.
Evaluate
Compare technical options, feasibility and cost-effectiveness transparently.
Plan
Translate systems, components and interfaces into a documented project basis.
Implement
Resolve technical questions and support implementation within the agreed scope of services.
Develop further
Add documentation, monitoring and digital processes where they create additional value.
