As independent consulting engineers we focus on energy-saving buildings, ecological constructions and quality management. We mainly offer speaker services and expertise, which also include standardisation processes. Furthermore, we also offer consultations and special calculations, for colleagues as well of course.
We write expert reports on the calculation of energy balances (all German and general European calculation procedures), the thermal behaviour of buildings or rooms and the energy consumption of buildings. We also resolve the issue surrounding the reason(s) for moisture damage in your insulated building parts.
For the investigation of deviations from planning values and real consumption values.
We support you in standardisation committees and research projects with questions about energy-efficient buildings.
As a speaker Mr Stelzer focuses on teaching new knowledge, new technical and public rules and regulations for colleagues that work on the topic of energy efficiency.
Climate change is progressing dramatically and there are many insights into this phenomenon. Mr Stelzer provides presentations on motivation for energy-efficient buildings or best practice examples.
Mr. Stelzer offers these in a variety of topics about energy-efficient and ecological construction.
Nowadays the design of good buildings is only possible with special software. For some software products Mr. Stelzer offers user workshops including the theoretical base.
We support you with special calculations and simulations for your projects as an energy consultant. Especially if these calculations are rarely performed special services for you.
Simulations for a 1-D hygrothermal assessment of your construction in acc. with EN 15026 with WUFI Pro. To keep your construction parts dry.
The simulation tool, Polysun, can simulate the energy systems of heating, refrigieration and electrical power, even with solar energy, geothermal probes, electrical power generation or electric mobility in the context of buildings.
Sometimes the right weather data set for a reasonable result of your calculation is simply missing. We provide the appropriate weather data with the Meteonorm software, with which the individual shading influence can also be included.
We offer all services, including public funding in Germany in the field of ecological constructions for healthy living. We support you in achieving new passive houses and nearly zero energy buildings or in refurbishments with passive house components. We are listed on the "Energie-Effizienz-Experten" list of dena.
Founded in Cologne in 1998, the consultants have been based in Reutlingen since 2007 and offer their services throughout Europe.
