Ventilation/air conditioning technology competence week

Specialist event for the planning, operation, and optimization of ventilation and air conditioning technology

Ventilation/air conditioning technology competence week Online Event

The 2026 Ventilation and Air Conditioning Technology Competence Week offers you the opportunity to continue your education in a practical, compact, and convenient online format over four days from April 27 to 30.

In free daily specialist presentations, you will receive concise expertise on current requirements, technical developments, and practical solutions relating to ventilation and air conditioning technology—with a focus on residential and non-residential buildings.

Together with other companies in the industry, we at Mitsubishi Electric Living Environment Systems are participating again and helping to shape the program—in a practical, application-oriented manner and on an equal footing. Take advantage of the direct exchange with experts and bring your knowledge up to date.

New in 2026: A single registration is valid for all four days. The event is free of charge and takes place entirely online. Join us—our colleagues look forward to your participation!

Key topics of the week

program

Day 1 // Ventilation technology in residential buildings

On the first day, the focus will be on residential ventilation —from decentralized and centralized systems to basement ventilation, measurement, adjustment, and maintenance.

9:00–10:00 a.m. | Helios:Innovative decentralized ventilation systems with and without heat recovery for residential buildings
10:00–11:00 | Hottgenroth:Fresh air right from the start – planning and implementing central ventilation systems correctly
11:00 a.m.–12:00 p.m. | Helios:Ventilation in basement rooms – what matters
12:00–12:00 | Lunch break
1:00–2:00 p.m. | Wöhler:Checking air volumes—adjustment according to planning specifications: Metrological solution
2:00–3:00 p.m. | Wöhler: Ventilation system maintenance:
I see something you don't see

Day 3 // Air conditioning technology

The third day delves deeper into air conditioning technology —thermal comfort (DIN EN ISO 7730), cooling load calculation (VDI 2078), volume flow & outside air ratio (DIN EN 16798), and h,x diagram as a basis for component design.

9:00–10:00 a.m. | Prof. Dr. Hahn: air conditioning technology
10:00–11:00 | FGAS - Heat pump
11:00 a.m.–12:00 p.m. | Hottgenroth:More than just calculations – building simulation for precise cooling load determination
12:00–1:00 p.m. | Lunch break
12:00–1:00 p.m. |Helios & Mitsubishi Electric: Topic: Air conditioning technology
2:00–3:00 p.m. |Hottgenroth& Mitsubishi Electric:LLWP rating according to DIN 18599
3:00–4:30 p.m. | Event – Tasting

Closing round with online tasting, scheduled for Wednesday, 3:00 p.m. (limited gourmet package available for registrations before April 6, 2026; non-alcoholic option available). Details from the organizer.

Day 2 // Ventilation technology for non-residential buildings

Day 2 highlights HVAC concepts for non-residential buildings – from smart solutions and 3D planning to hygiene/VDI 6022 to schools, daycare centers, and healthcare (DIN 1946-4).

9:00–10:00 a.m. | Helios:Ventilation technology in transition – from current standards to smart solutions (Non-residential buildings / public buildings)
10:00–11:00 | Hottgenroth:From model to reality – efficiently implementing 3D planning in non-residential buildings
11:00 a.m.–12:00 p.m. | VDI 6022 Sheet 8: Cleaning and Sheet 8.1: Qualification
12:00–1:00 p.m. | Lunch break
1:00–2:00 p.m. | Helios:Ventilation for schools and kindergartens – what matters (public buildings)
2:00–3:00 p.m. | Hottgenroth: Hygiene, standards, practice: DIN 1946-4 explained in a nutshell

Day 4 // Innovations / Special Topics

Finally, we will look at digital planning and efficiency: AI, BIM, and workflows, leakage testing of HVAC systems, and funding opportunities (e.g., BEG EM) in existing non-residential buildings.

9:00–10:00 a.m. | Hottgenroth:The future of planning: Working efficiently with AI, BIM, and digital workflows
10:00–11:00 | HVRF / HBC Controller
11:00 a.m.–12:00 p.m. | Pitfalls in leak testing of HVAC systems during installation, including the use of leak testing devices and the necessary knowledge acquisition
12:00–1:00 p.m. | Lunch break
1:00 p.m.–2:00 p.m. | ecogreen:Funding opportunities for ventilation systems in existing non-residential buildings – increase efficiency and secure subsidies
