Webinar: Correct ventilation in winter

In this webinar, you will learn more about why proper ventilation is crucial for a healthy indoor climate in the cold season.
Learn practical tips and tricks to prevent mold growth, save energy and improve the quality of your home. Our Technical Manager Michael Merscher will go through the following topics with you:
Why ventilation is important
We often only think about ventilation when unpleasant odors arise or we need fresh air. In such cases, we briefly open the window, air it out or leave it tilted. Some households now have a ventilation system installed which, in the best case, automatically provides fresh air so that we are hardly aware of airing the room.
The importance of ventilation for buildings
However, regular ventilation is essential for our buildings. The main reason for this is to reduce moisture in the apartment or house. Uncontrolled moisture can cause considerable damage to the building fabric and furnishings in the long term. In addition, we are all aware of how harmful mold can be to health, which is encouraged by inadequate ventilation.
Practical tips for correct ventilation
In this webinar, we will give you practical tips and tricks on how to ventilate properly, simply and effectively. This webinar lasts just 45 minutes and offers you compact, immediately applicable tips for the winter. This seminar is accredited by the Engineering Chamber of Niedersachsen with one continuing education point and by the Architects Chamber of Brandenburg with one teaching unit as an external training event. We would be happy to provide you with a certificate of participation afterwards.
We look forward to seeing you!

Webinar: Contract law and individual contractual agreements

In this webinar, you will learn everything about contract law and individual contractual agreements.
Legally secure contract design is a central aspect of planning and installing home ventilation systems. In our webinar, we provide practical knowledge on the technical and legal foundations to minimize liability risks and ensure secure contract conclusions. Michael Merscher, Technical Director of LUNOS, will conduct the webinar together with a specialist lawyer in contract law.
Technical and contractual basics in Home ventilation
- Contract security in residential ventilation: Why are clear contracts essential?
- Technical requirements: Minimum requirements, relevant standards (DIN 1946-6, GEG) and contractual security.
- Liability and risks: How can risks for planners and installers be minimized?
- Practical example: Creating a ventilation concept with important contractual clauses.
Legal foundations and watertight contract design
- Types of contracts: Work contract, service contract, and purchase contract – differences and rights.
- Contract design: Service description, warranty obligations, and damage compensation regulations.
- Conflict avoidance: Common disputes, the importance of acceptance, and documentation.
- Checklist & practical examples: Important components of a legally secure contract.
Goal of the webinar: Participants will gain comprehensive knowledge to create legally secure contracts, recognize potential liability pitfalls, and avoid conflicts.
This seminar is accredited by the Engineering Chamber of Niedersachsen with 2 continuing education points and by the Architects Chamber of Brandenburg with 2 teaching units as an external training event. We would be happy to provide you with a certificate of participation afterwards.
Sustainability in home ventilation

Even with the start of the carnival season, we have concentrated knowledge. That's why we're launching an exciting webinar with a duration of 111 minutes on 11.11.2025 at 11:11 am. The topic: How sustainable are ventilation systems?
Michael Merscher, our Technical Manager, together with Dr. Daniel Scherz, the expert for sustainability in the construction and energy sector, will go through the following topics with you:
- The importance of heat recovery and its savings potential
- Why the production and use of materials are important for sustainable energy consumption
- We show what our ventilation units do, how they are manufactured and what you can expect from the ventilation units
- We explain the integration of ventilation units in certified sustainable buildings and answer the questions we are most frequently asked
This seminar is accredited by the Engineering Chamber of Niedersachsen with 2 continuing education points and by the Architects Chamber of Brandenburg with 2 teaching units as an external training event. We would be happy to provide you with a certificate of participation afterwards.
We look forward to seeing you!
