Belimo ZoneEase™ VAV – Controlling of CO2, temperature, and volumetric flow (in German)

Duration: 24 minutes

Health, well-being, and productivity greatly depend on room climate. Therefore, good indoor air quality is fundamental to building design and operation. Variable volumetric flow controllers, also known as VAV, enable precise control of air volumetric flows via control sequences directly integrated into the VAV actuator.

Belimo ZoneEase™ VAV is an easy-to-operate VAV-based zone control ecosystem. The ZoneEase VAV solution simplifies the commissioning process. It provides commissioning and maintenance support via the cloud and smartphone to enhance the user experience and reduces project complexity and downtime while increasing connectivity, data transparency and cost-efficiency.

Intelligent control butterfly valves (in German)

Duration: 38 minutes

Say goodbye to high energy consumption, inefficiency, discomfort, and sky-high costs caused by obsolete valves! Thanks to the innovative control butterfly valves from Belimo with nominal diameters from DN 100 to DN 300, these problems are now a thing of the past – just like the hassle of finding compatible Belimo RetroFIT+ solutions. 

Exactly what these solutions are and why they are such a game changer can be found in the following video tutorial, which focuses on the following points and questions:

• Use of butterfly valves as control valves. How does Belimo manage to use intelligent butterfly valves as control valves?

• What are the advantages and disadvantages of this solution and where can it be used?

• How can control butterfly valves prove their worth over globe valves, and when is which technology appropriate?

European Green Deal: Help! Or Hurrah!? (in German)

Duration: 23 minutes

The European Union's Green Deal has also had a concrete impact on the HVAC and technical building services sectors. But what exactly are the implications, and what can market participants and suppliers expect to happen? In this video tutorial, Belimo would like to address the following points and questions, among others: 

• Overview of the regulatory landscape: What does the Green Deal mean for normative legislation such as the Energy Performance of Buildings Directive (EPBD), the Energy Performance of Buildings Act (EPBG) and the EU's taxonomy and criteria for sustainable economic activity in the context of Environmental Social Governance (ESG)?
• Who will implement the agreed changes, who will be responsible for them, and who will be affected by the new Green Deal rules?
• How will this work in practice? Belimo wants to show individual ways and solutions to answer these questions.  

When do I need motorised fire dampers? (in German)

Duration: 30 minutes

Specialist planners and technical building services companies are often faced with the question of when fire dampers should be motorised as shut-off devices in ventilation systems. Unfortunately, in many cases, the approved fire protection concept does not provide specifics in this regard. "Where does it say that?" is one of the most frequently asked questions in this context.

The educational video looks at the different reasons for motorising fire dampers:

• What does the legislator require in regulations such as the German Model Building Code (MBO) and specific building regulations?
• What are the requirements of the German Model Ventilation System Guidelines (M-LüAR)?
• What can be said about the generally accepted rules of technology?
• What are the benefits of motorised fire dampers to the building owner?

Belimo RetroFIT+ – Increasing energy efficiency in existing plants (in German)

Duration: 23 minutes

The existing air-conditioning systems in existing buildings – heating, cooling and ventilation – often offer plenty of potential for energy savings. After all, intelligent control of heating, cooling and ventilation loads contributes significantly to the energy efficiency of buildings. Belimo has the right solution in its portfolio for these purposes and offers a comprehensive concept for increasing energy efficiency with the topic "RetroFIT+".

In this educational video, we present a Belimo task force that analyses existing systems and develops proposals for increasing efficiency, for example by using other hydronic circuits or pressure-independent valves. Find out which tools can be used to achieve this and what role intelligent field devices such as the "Energy Valve" can play.

Consumption-based billing of energy costs for mechanical ventilation (in German)

Duration: 23 minutes

In commercial buildings with mechanical ventilation, it has been common practice for many years to allocate ventilation costs to the various occupants according to a pre-defined key. The distribution key used is usually the area allocated to each occupant relative to the total ventilated area of the building. However, this approach does not take into account or support newer trends and requirements to further reduce energy consumption in buildings.

What are the options available today for consumption-based billing of energy costs for mechanical ventilation? What is required by the Buildings Energy Act? What are the technical requirements? And when does consumption-based billing make economic sense?

These questions are the focus of this educational video.

The seminar will focus in particular on the following points:
