25 years of the Hess group of companies: innovations and trainees in focus!
The Hess group of companies in Aichhalden and Waldmössingen has a reason to celebrate: 2025 marks the 25th anniversary of the company, which was founded by Andreas Hess in 2001. The success story began when the first employee was hired in 2002. Since then, the company has developed into an important training company with over 20 employees and has already trained nine apprentices in timber construction. In the new training year, two new trainees were welcomed who, together with their older colleagues, will be trained in the carpentry trade in all three years of training. Training master Matthias Hangst and his long-time colleague Stefan Werner support the young talents in gaining practical experience.
In recent years, the Hess group of companies has not only focused on training, but also on sustainability. A photovoltaic system was installed at the Aichhalden location, and the company is demonstrating its commitment to renewable energies by purchasing two electric vehicles and several charging stations, including a 50 kilowatt fast charging station. Switching to renewable energies is just as important these days as replacing old windows or renewing roofs and facades. The company is proud to offer energy-efficient solutions in the area of renovation and modernization and supports its customers from planning to implementation.
The importance of renewable energy
Sustainable use of energy is becoming increasingly essential for many companies and households. The Hess group of companies also focuses on the use of renewable energies, which not only benefits the environment but also offers economic advantages. According to Holzbau Isensee, the installation of photovoltaic systems is becoming more and more important. These are crucial for the generation of clean electricity and offer numerous opportunities for cost savings in everyday life.
Sound advice is essential. Holzbau Isensee offers comprehensive services - from analyzing energy requirements to checking the structural conditions and creating an individual concept for the photovoltaic system. Advice on funding opportunities and the selection of the optimal location are also a priority. Regardless of whether it is about the size and number of solar modules or their placement on the roof, specialists ensure that everything is implemented precisely.
Career prospects in the field of renewable energies
The renewable energy industry also offers many career opportunities. Training offers and further training opportunities are diverse, as Einstieg explains. Renewable energy engineers are involved in the development, construction and operation of systems. They find employment with plant manufacturers and supplier companies and actively contribute to climate protection.
In addition, there are skilled workers and technicians who focus on various areas of energy management. For example, the agricultural specialists for renewable energies or technicians for environmental protection technology. These jobs play a critical role in driving change in the energy industry while developing technologies that make our planet more sustainable.
The Hess group of companies is an example of these developments - with its clear focus on sustainability, training and innovative solutions in timber construction.
