Apartment building upgrades

All apartments need to be upgraded at some stage. In terms of both time and cost, it is often a challenge to carry out essential ventilation upgrades for both the owners of older properties and for the board of a housing association, where the stock of housing units require refurbishment.

Hassle-free ventilation upgrades

One solution for an upgrade that is relatively easy and cost-effective to install is a system that is automatically demand-controlled for each individual unit in an apartment building. This solution involves connecting a central ventilation unit via main ducts or a shaft to a distribution cabinet for each landing.

Neat duct casing

From the technical cabinet/fire cartridge, ducting is placed into the apartment hallway and through to a distribution box fitted there. A loop with ducts for the supply and extract air is installed against the angle between the ceiling and wall in the hallway. This loop is then covered by prefabricated duct casing for a neat, discreet appearance. For rooms requiring supply or extract air, holes are then placed in the respective walls.

Technical cabinet fixes the problem

In the stairwell, opposite the door to each apartment, a technical cabinet is installed, containing motorised dampers and sensors for air quality, humidification and temperature. These cabinets are then docked to a fire cartridge with a fire damper in order to raise the standard of fire safety.

No inconvenience for neighbours

The central ventilation unit is pressure controlled. Each apartment is regulated independently of the neighbouring apartments through the technical cabinet, where the air flow adapts automatically to the signal from the air quality and humidity sensors.

While these upgrades enhance ventilation for maximum comfort for both the occupants and building users generally, they also ensure energy-efficient operation in that ventilation is provided only on a needs basis.

The advantages of a centralised unit

  • Demand-controlled ventilation in each apartment, with auto-adjustment of air quality and humidity
  • High energy-efficiency
  • Integrated mechanical fire protection
  • Quick and cost-effective installation

Factors to consider in upgrade projects

  • Solutions for every budget

  • The long-term and most energy-efficient solution is to convert to an air-to-air heat exchange system

  • The choice of a centralised or decentralised solution should be based on the existing installation

  • Select products/systems that are connectable, demand-controlled and future-proofed
