Building technology

Innovative & energy-efficient

Over many years, we have specialised in the areas of building technology, energy efficiency, holistic building simulations, system simulation for renewable energy and the specialist planning of technical building equipment. We work with you to develop innovative solutions to make your buildings more energy-efficient, comfortable and sustainable.

// Our areas of responsibility

Building technology and TGA (technical building equipment)

Our services cover all aspects of technical building services – from heating, sanitation, ventilation and cooling to the integration of renewable energies such as PV systems, solar thermal energy and biomass. We develop innovative system technologies, taking into account the individual needs of your buildings.

Energieeffizienz und Nachhaltigkeit

Our specialist planning aims to maximise the energy efficiency of your buildings. We focus on renewable energies such as solar energy, geothermal energy using ground collectors, which work in combination with heat pumps or hybrid systems to reduce your energy costs and minimise the environmental impact. Our focus is also on self-sufficiency and neighbourhood concepts that promote independence from external energy sources.

Comfort and health

People as warm-blooded creatures are at the centre of our planning. Our low-temperature systems ensure optimum thermal balance and comfort in your rooms. We work with you to develop a customised vitality concept, taking into account the aspects of comprehensive building temperature control, energy-rich air quality through ecological surface design, as well as the energetic enrichment of drinking water, the quality of which, like spring water, ensures the vitality of the homeowner.

Innovative solutions

Our experts develop lighting and solar concepts that utilise natural radiant heat to save energy. We integrate intelligent systems and combine different technologies to achieve the best benefits for your building.

Efficiency and sustainability

Planning with parallel surface heating ensures even heat distribution in the building and fast response times. This leads to lower energy consumption thanks to carefully planned surface heating.

Cooling and comfort

We integrate passive and active cooling options to optimise comfort in your buildings, especially in the warmer months.

If you are looking for holistic specialist planning for building technology, energy efficiency and sustainability, we are your ideal partner. Our expertise in combining different systems and benefits enables you to shape the future of building technology and benefit from significant energy savings.

What is energy consulting and why is it important?

Energy consulting is an important part of the energy transition and plays a crucial role in reducing energy consumption and CO2 emissions. It offers consumers, companies and public organisations the opportunity to improve their energy efficiency and reduce costs.


But what exactly is energy consulting? Energy consulting is a professional service in which experts analyse the energy consumption of a building or system and identify potential for optimisation. Various aspects such as heating, ventilation, lighting, insulation and renewable energies are taken into account.


Why is energy consulting so important? Climate change is one of the greatest challenges of our time. In order to achieve the climate targets, we need to reduce our energy consumption and increasingly rely on renewable energies. Energy advice helps to identify potential savings and implement measures to increase efficiency.


With professional energy advice, consumers and companies can not only reduce their ecological footprint, but also save costs in the long term. This is because more efficient energy utilisation can significantly reduce both electricity and heating costs.


A qualified energy consultant also offers customised solutions that are tailored to the specific needs and requirements of the customer. Not only are technical aspects considered, but financial and legal framework conditions are also taken into account.


Energy advice can be of great importance for private households as well as for companies and public institutions. It supports the selection of suitable energy-saving measures, provides information on funding opportunities and accompanies the entire process from planning to implementation.


Conclusion: Energy counselling is an indispensable building block on the way to a sustainable energy supply. It helps consumers and companies to reduce their energy consumption, cut costs and make a contribution to climate protection. Professional energy advice offers customised solutions that are tailored to the specific needs of the customer.

Why do you need an energy consultant? The advantages at a glance

An energy consultant is an expert who can help you optimise your energy consumption and reduce costs. But why is it important to hire an energy consultant? Here is an overview of the benefits:


Recognising potential savings: An energy consultant analyses your current energy consumption and identifies potential savings. By taking targeted measures, you can reduce your consumption and thus save costs in the long term.


Customised solutions: Every household and every company has different requirements and needs. An energy consultant develops customised solutions that are tailored to your specific circumstances.


Utilising specialist knowledge: Energy efficiency is a complex topic with many different aspects. An energy consultant has the necessary expertise and is familiar with the latest technologies and trends. They can help you make the right decisions and benefit from their expertise.


1. utilise funding opportunities: There are often government funding programmes for energy-efficient measures. An energy consultant is familiar with these programmes and can help you apply for funding. This can provide you with additional financial support.


2. time saving: The search for the best energy-saving measures can be time-consuming. An energy consultant takes this work off your hands and presents you with the best options. This saves you time and allows you to concentrate on your core business.


3. act in an environmentally friendly way: By optimising your energy efficiency, you actively contribute to climate protection. An energy consultant will help you to reduce your ecological footprint and make a contribution to sustainability.


Conclusion: An energy consultant is a valuable partner when it comes to optimising energy consumption and reducing costs. With their expertise and experience, they can develop customised solutions and identify potential savings. They also know about funding opportunities and can help you apply for financial support. Hire an energy consultant and benefit from the numerous advantages they offer.

What does an energy consultation cost?

The cost of an energy consultation can vary depending on the scope and type of consultation. There are different types of energy consultations, such as an on-site consultation, a construction supervision or an energy-related refurbishment consultation. Prices can also vary from energy consultant to energy consultant.


For an on-site consultation, in which an energy consultant analyses your building and gives you individual recommendations for improving energy efficiency, the costs in Germany can be between 200 and 800 euros. The exact costs depend on factors such as the size of the building, the location and the scope of the consultation.


The costs can be higher for construction supervision, where the energy consultant supervises the new build or refurbishment and ensures that the energy-efficient standards are met. Depending on the scope of the project and the duration of the support, prices can amount to several thousand euros.


It is important to note that there are state subsidy programmes that can cover part of the costs of an energy consultation. It is therefore worth finding out about possible subsidy programmes.
