The building is the most significant wooden apartment building in Finland, and also the largest wooden apartment building in Europe. It was completed as a social rental housing project in 2015 by Rakennusliike Reponen Oy, Suomen Vuokrakodit Oy, TA-Asumisoikeus Oy, and the City of Vantaa. The building was introduced to visitors at the Vantaa Housing Fair in summer 2015. The wooden building has a total of 186 apartments, of which 107 are rental and 79 are right-of-occupancy apartments. With a total floor area of 10 120 m2, the highest sections of the building have 7 floors.

An intelligent ventilation unit is part of the smartness of the building

The main requirements of the ventilation system of the wooden apartment building in the Vantaa Housing Fair area were energy-efficiency, ease of use, and remote monitoring.

An apartment-specific ventilation system was selected and implemented using Vallox 096 MV ventilation units. As each apartment has its own ventilation unit, the residents can adjust the ventilation based on their specific needs and preferences by selecting the desired efficiency: At home, Away, or Boost. The ventilation efficiency is selected using easy-to-understand icons, so no language skills are needed. The apartment-specific ventilation system is at its best when little attention needs to be paid to its use. The need-based boosting of the ventilation is done automatically.

The standard equipment of MyVallox ventilation units include an integrated humidity sensor, which boosts the ventilation after sauna and showering. This ensures that wet premises dry quickly after use and that the building’s structures remain healthy without the residents having to worry about them. Ventilation and air extraction is increased automatically also during cooking. The integrated timer and humidity control ensure that the Boost profile is not left turned on for too long after the need for it has ended. This saves energy and makes life more comfortable.

For remote monitoring, MyVallox ventilation units have been connected to Fidelix house automation.


Most of the technology is not visible

At Puumera, ventilation units are located inside a separate housing technology cabinet in the stairwell. Other technology needed in a smart building is also located inside the cabinet, and these can be accessed without going into the apartment. The location of the ventilation unit is excellent also from the ventilation noise point of view, and the filters can also be serviced without going into the apartment.

The control panel of each MyVallox ventilation unit is located inside the apartment. The user can use the control panel for adjusting ventilation efficiency and for viewing data relating to apartment-specific ventilation and to the operation of the unit, including history data. However, in order to prevent user errors, the user has no access to expert settings. MyVallox control panel has three ready user levels, of which the best can be chosen for each site during setup.

Efficient removal of cooking smells contributes to high-quality indoor air. To ensure the best results, this function must be easy to use. At this site, extraction is increased by simply opening the boost damper of the cooker hood. Information is transmitted to the MyVallox ventilation unit of the opening of the boost damper of the cooker hood, and ventilation is increased automatically. The position function of the damper is linked to the programmable input of the ventilation unit. This means that ventilation can be increased more when the cooker is used than after a shower, for example. The programmable input of the MV unit also allows for increasing the speed of the supply air fan when the extraction fan is used during cooking to compensate for the under pressure generated when the cooker hood damper is opened.

MyVallox ventilation units have Modbus readiness as a standard feature and they have been connected to Fidelix house automation via a ModBus RTU channel. A wide range of data can be transmitted from the ventilation unit to house automation including all temperatures that are important for the operation of the ventilation unit, apartment temperature, humidity percentage, and fan speeds. A limit value can be set for all values, deviation from which will trigger an alarm. The efficiency of ventilation can also be controlled remotely and the settings of the unit, e.g. supply air temperature, can all be modified in one place. In rental apartments, ventilation can be reduced when the apartment is unoccupied.
