VENTILATION Solutions by NILAN Building benefits Daily ventilation prolongs the life of the building as humidity and condensation are eliminated. Equally important, ventilation reduces the need for costly maintenance as the building is kept in healthy conditions.

Decentralised concept at a glance When you choose a decentralised ventilation system with heat recovery, you basically install a one-family-house solution in every apartment. The apartments are equipped individually with closed ventilation and heating systems, including separate tubing. The utility room is 'the heart' of the apartment from where the ventilation unit regulates the indoor climate by extracting stagnant and stale air and replacing it with fresh, filtered and heated air. Nilan recommends three different solutions (see pages 8-9) to accommodate varying requirements and budgets –...

VENTILATION Solutions by NILAN Supply air The fresh, filtered and heated supply air is distributed to all living rooms in the apartment to provide a healthy indoor climate. Utility room Every apartment is equipped with its own utility room with a ventilation unit, heat source and electrical panel. Fresh air Every apartment has its own intake valve through which fresh air is fed to the ventilation unit. Extract air The ventilation unit extracts stale and stagnant air from the apartments. In the kitchen, the extract air leaves the room through a valve and/or the range hood, and in the...

Design and planning advantages One of the most important benefits of the decentralised solution is the fact that all central ducting is made redundant due to the individual closed tubing system in each apartment. Hence, the decentralised solution requires less space compared to a centralised solution and denies any transfer of odours between the apartments. Furthermore, the elimination of central ducting means lower heat loss. Combined with higher temperature efficiency, this makes the decentralised solution a more energy efficient choice. When you install a decentralised system rather than...
