How modern hybrid ventilation works in energy-efficient buildings

The hybrid ventilation system operates based on intelligent switching between two modes of operation. In favorable weather conditions, it utilizes natural chimney draft, taking advantage of temperature and pressure differences. When external conditions are insufficient, energy-efficient fans automatically activate to support air exchange.

Key elements of the hybrid system

  • Hybrid caps – mounted at the ends of ventilation ducts
  • Adjustable air inlets – providing controlled fresh air supply
  • Control systems – monitoring conditions and automatically switching modes of operation
  • Humidity and temperature sensors – optimizing system performance

From our many years of experience in the installation industry, it follows that a properly designed hybrid system can reduce energy consumption by up to 50% compared to traditional mechanical ventilation. This is particularly important in the context of rising energy costs and the requirements for energy efficiency in buildings.

Why hybrid ventilation is the future of energy-efficient construction

At Onninen, we see clear market trends indicating the growing importance of hybrid solutions. We offer AWENTA hybrid ventilation systems, which are perfectly suited for modern construction.

Economic benefits of hybrid systems

Aspect Traditional ventilation  Hybrid ventilation
Energy consumption  Continuous operation of fans  Periodic operation as needed
Operating costs  High (150-300 PLN/year) Low (30-80 PLN/year)
Noise level   Continuous noise from fans   Practically silent operation
Independence from conditions Limited  Full automation

As a leader in the installation market, we recommend hybrid solutions especially for passive and energy-efficient buildings, where every kilowatt of saved energy matters for the overall energy balance of the facility.

Practical applications of hybrid ventilation in various types of buildings

In Onninen's assortment, you will find hybrid solutions tailored to various needs. Our experience shows that these systems perform well in a wide range of applications.

Energy-efficient single-family homes

In single-family homes, hybrid ventilation allows achieving the standards of low-energy buildings without the need for expensive recuperation systems. Hybrid caps operate with a power of only 5-15W, resulting in annual operating costs below 50 PLN.

Multi-family buildings

In multi-family construction, we offer systems that allow for individual control of ventilation in each apartment. This solution is particularly valued by developers who care about the comfort of future residents.

Commercial properties

Offices and service facilities require constant air quality with controlled operating costs. Our hybrid systems provide automatic adjustment of performance to the current occupancy of rooms.

Installation and service of hybrid ventilation systems

One of the greatest advantages of hybrid solutions is the simplicity of installation. At Onninen, we offer not only high-quality components but also comprehensive technical support for installers.

The system can be installed both in new buildings and during the modernization of existingAWENTIS I - A hybrid ventilation system set AW1-A facilities. It utilizes existing gravity ventilation ducts, significantly reducing installation costs. It is enough to install hybrid caps at the ends of the ducts and air inlets in the rooms.

Our specialists provide professional advice on selecting optimal solutions. Complete systems along with installation instructions and necessary technical documentation are available at all Onninen branches.

Frequently asked questions

What is hybrid ventilation?

Hybrid ventilation is a system that combines natural ventilation with mechanical ventilation. It operates gravitationally when weather conditions are favorable and automatically switches to mechanical assistance when natural air exchange is insufficient.

What are the operating costs of hybrid ventilation?

Annual operating costs are around 30-80 PLN. Hybrid caps consume 5-15W of energy and do not operate continuously, which significantly lowers electricity bills compared to traditional mechanical systems.

Can hybrid ventilation be installed in an existing building?

Yes, installation in existing buildings is possible and simple. The system utilizes existing ventilation ducts, requiring only the installation of hybrid caps on roofs and possibly air inlets in the rooms. No building permits are required.

How often does hybrid ventilation need servicing?

Service is required once a year. Hybrid caps should be cleaned and checked during the standard chimney inspection of the ventilation ducts. This is significantly less than for complex mechanical systems.

Does hybrid ventilation work in all weather conditions?

Yes, it provides effective air exchange regardless of the weather. In favorable conditions, it operates gravitationally, and when the wind stops or changes direction, mechanical assistance automatically activates, ensuring continuous ventilation.

What are the main advantages of hybrid ventilation for energy-efficient buildings?

The main advantages are energy savings of up to 50% and low operating costs. The system automatically adjusts performance to needs, utilizes natural forces when possible, and ensures continuous high air quality with minimal electricity consumption.

Is hybrid ventilation noisy?

No, it operates practically silently. Hybrid caps are installed on roofs away from living spaces, and low-power motors (5-15W) generate noise levels below 40 dB, which is inaudible in rooms.

How much does a hybrid ventilation system cost?

Installation costs range from 2000 to 5000 PLN depending on the size of the building. This is significantly cheaper than mechanical systems, and additional savings come from low operating costs and ease of installation in existing ducts.

Investment in the future of energy-efficient construction

Hybrid ventilation represents the ideal combination of traditional reliability with modern technologies. At Onninen, we are convinced that such solutions will dominate the construction of the future, where energy efficiency goes hand in hand with user comfort.
