Ventilation systems for controlled building ventilation
Ventilation systems ensure controlled air exchange in residential and commercial buildings. They remove stale indoor air while simultaneously supplying fresh outdoor air to interior spaces. This improves indoor air quality, supports moisture protection and contributes to the energy efficiency of modern buildings.
Especially in well-insulated and airtight buildings, traditional window ventilation or trickle ventilation is no longer sufficient to reliably remove moisture, pollutants and CO₂. A well-designed ventilation concept is therefore essential. Controlled building ventilation has become a key component of modern construction and usage concepts. Ventilation systems help to reliably remove moisture and ensure a consistently comfortable indoor climate.
Ventomaxx ventilation systems are designed to meet a wide range of requirements – from decentralized ventilation of individual rooms to central ventilation of entire building units.
What types of ventilation systems are available?
In general, building ventilation is divided into decentralized and central ventilation systems. Both concepts enable controlled airflow and can be applied depending on building type, usage and planning requirements.
Decentralized systems operate on a room-by-room basis and are particularly suitable for flexible solutions or buildings without duct systems. Central ventilation systems supply multiple rooms via a central unit and an air duct system.
Ventomaxx offers solutions for both concepts – from modular decentralized ventilation systems to central ventilation systems with heat recovery (HRV).
Decentralized ventilation systems
Decentralized ventilation systems enable targeted ventilation of individual rooms or usage units. The units are installed directly in the exterior wall or within the respective room, eliminating the need for a central air distribution system.
These systems are suitable for both new builds and renovations and can be flexibly adapted to different building structures.
Typical solutions include:
- air inlets (ALDs) for controlled fresh air supply
- decentralized ventilation systems with heat recovery (HRV)
- exhaust air systems for rooms with high moisture load (e.g. bathrooms or kitchens)
- supply air systems for delivering fresh air to individual rooms (e.g. bedrooms)
- wall installation components for easy integration of ventilation components in new builds
Thanks to their modular design, decentralized ventilation systems can be flexibly integrated into different room and building concepts.
Central ventilation systems
Central ventilation systems ensure uniform ventilation throughout an entire building unit. A central ventilation unit distributes air via a duct system to different rooms while simultaneously removing exhaust air from functional areas such as kitchens, bathrooms or utility rooms.
Many systems operate with integrated heat recovery (HRV): the heat from the exhaust air is used to preheat the incoming outdoor air. This reduces heat losses and significantly increases the building’s energy efficiency.
Central ventilation systems are commonly used in new builds, multi-family housing and energy-efficient residential buildings.
Control of modern ventilation systems
For demand-based operation, fan-assisted ventilation systems are controlled via control units. Depending on the system, integrated or central control solutions are used.
The control system allows you to:
- adjust ventilation levels
- define time programs
- connect multiple units
- adapt airflow rates to usage and occupancy
Ventilation systems are complemented by system-compatible accessories such as roomside covers, facade terminations, filters and installation components.
As a manufacturer of modular ventilation systems, Ventomaxx develops solutions that can be flexibly adapted to different buildings, usage concepts and technical requirements.
Frequently asked questions about ventilation systems
What are ventilation systems?
Ventilation systems are technical systems for controlled ventilation of building units. They ensure continuous air exchange by removing stale indoor air and supplying fresh outdoor air.
What is the difference between central and decentralized ventilation?
Decentralized ventilation systems operate room by room and are installed directly in individual rooms. Central ventilation systems supply multiple rooms via a central unit and a duct system.
When is decentralized ventilation useful?
Decentralized ventilation systems are particularly suitable for renovations, individual apartments or buildings without duct systems. They enable targeted ventilation of individual rooms and can be integrated into existing buildings with relatively low structural effort.
