Ventilation system D
Ventilation system D ensures a healthy indoor climate by mechanically supplying fresh air and extracting stale air. A heat recovery unit (HRV) uses warmth from the extracted air to heat the supply air. As a result, system D is an energy-efficient and comfortable ventilation solution, which is widely used in new build homes and energy-efficient renovations.
Hybalans+
An air distribution system that ensures flexible and efficient air distribution within the ventilation system. Due to its modular construction, Hybalans+ is easy to adapt to the situation in the home and keeps the air pathway clear.
In practice, that means:
- Modular and flexible design that moves with the design
- Quick and easy to install, with fewer site operations
- Suitable for new builds and renovations, also for varying installation spaces
EasyAir EPS & EPP insulated ducts
Lightweight ventilation ducts with a high insulation value. Due to their low weight and fixed shape, the ducts are pleasant to work with and easy to integrate into the air path.
In practice, that means:
- Easy to handle, even in tight spaces
- Suitable for modern and existing buildings, for new builds and renovations
- Ideal for connecting ventilation systems, with a clear system structure
Ventilation in an energy-efficient home
The Netherlands is moving further towards energy-efficient and gas-free homes. Many houses are well-insulated and use solutions such as a heat pump or a hybrid heating system. This reduces energy consumption, but also limits natural ventilation.
In this type of dwelling, a good ventilation system is therefore essential to keep the indoor climate healthy and comfortable.
Ventilation system D connects well here. The supply and exhaust of air are fully mechanically regulated, making the airflows controllable and the system work well with the high insulation values of modern homes.
Heat recovery saves energy
Ventilation system D uses a heat recovery unit (HRV). The heat from the extracted air is used to pre-heat the fresh outside air. This conserves heat while the home is continuously ventilated.
This offers clear advantages in practice:
- Minder warmteverlies in de woning
- Lagere energiekosten
- Comfortabelere toevoerlucht
In contrast to ventilation system C, with system D, cold outside air is not directly introduced into the home. The air is preheated first, which increases comfort and means the heating system has to do less supplementary work.
Requirements for a healthy indoor climate
Insufficient ventilation can lead to complaints such as fatigue and headaches, but also to moisture problems and the accumulation of pollutants in the home. Good ventilation is therefore a basic condition for a healthy indoor climate.
The BBL (Environment of Buildings Decree) stipulates the minimum amount of fresh air that must be supplied and extracted per hour. For renovation projects, it is often advisable to base calculations on new-build requirements where possible. This ensures that the ventilation system is better aligned with current insights and the comfort level of modern homes.
When designing a ventilation system, it's not just about the ventilation rate. These factors are also crucial for proper operation:
- De positie van ventielen
- De functie van de ruimte
- De luchtstromen door de woning
That's why Burgerhout advises installers to look beyond the minimum requirements. With our calculation software, you can easily create a reliable ventilation calculation per room, providing a solid basis for a system that works well in practice.
Comfortable ventilation with system D
With ventilation system D, both air supply and exhaust are fully mechanically controlled. Fresh air is supplied in a controlled manner and pre-heated, while polluted air is exhausted. This ensures a stable indoor climate without draughts.
A good design is also important for system D. Pay attention to:
- De juiste capaciteit per ruimte
- Een logische kanaalopbouw
- Quiet airflows
With Burgerhout software, you can easily calculate the correct capacity and assemble a system that is correct in design and can be installed plug-and-play.

Ventilation system C or D?
Ventilation system C is often used in renovations where space for additional ductwork is limited. The system is practical and effective, provided it is well designed and suited to the home.
Is there indeed enough space available? Then ventilation system D is often the better choice. This system offers more control over the airflows and increases comfort in the home.
Why?
- heat recovery heats the supply air with heat from the exhaust air
- less energy loss
- less chance of draughts
- more control over airflow
Ventilation system D ensures more comfort and is often the most sustainable solution when the situation allows.
