Enervent Zehnder ventilation equipment solutions were customized for the valuable building on Bulevardi in Helsinki

In the spring of 2022, the valuable property on Helsinki’s Bulevardi will be renovated back into high-quality apartments after being in commercial use for a long time. The architect Arkkitehtitoimisto Neva, which specializes in historic buildings, has been responsible for the design. The material and equipment choices of the neo-renaissance building have been made carefully to the smallest detail, taking into account the spirit and history of the house.

There will be 28 apartments in the building on Bulevardi 14. They range in size from a comfortable studio apartment to several hundred square meters of representative housing. In addition, the complex includes 11 commercial premises, of which some are aimed at consumer customers and are located at street level.

The ventilation of the valuable building is implemented with modern technology. The ventilation of each apartment is tailored for the apartment. Like all other products selected, the ventilation equipment has a high standard. Enervent Zehnder supplies ventilation units for all apartments and commercial premises – a total of five different unit models are required.

The building technology is being renewed under the supervision of the Helsinki City Museum

Heikki Sivonen is responsible for Lämpökarelia’s Southern Finland unit, which is responsible for the renovation of the HVAC technology in the building. The responsibility is considerable, as the entire building and building technology of the building will be renovated. An additional challenge is that no visible changes may be made to the historic facade of the house.

– Together with the designer, it was our responsibility to find the best solution and equipment for the ventilation. Our goal was to have units from the same supplier in all premises, which always facilitates logistics and planning of installation work. It will continue to play a role in future service and warranty matters. Enervent Zehnder was able to put together a customized package that corresponds to our request for quotation, Heikki Sivonen says.

Sivonen was already familiar with Enervent Zehnder’s products from previous projects.

– Enervent has rotary heat exchangers suitable for the northern climate in all its units. The units are easy to use and user friendly. In addition, they are elegantly simple on the outside which makes them fit unobtrusively into the premises of Bulevardi 14 type objects, where all users appreciate the high-quality finish, confirms Sivonen.

Suitable ventilation solutions for all squares metres

The apartment-specific ventilation equipment has been carefully selected for the dwellings in Bulevardi 14, considering the requirements and special needs of apartments of different sizes. The airflow capacity of the ventilation unit and its location determine the best option for each apartment.

– Our smallest units are compact ventilation units that are equipped with electric after heating. In smaller apartments, the ideal use of space has also been considered. In these, the Salla ventilation unit is imperceptibly placed, for example, on top of a wardrobe. Larger apartments have their own utility rooms, where it has been natural to place the unit. Correspondingly, the air volume demand of these apartments is higher, and they also provide cooling for each apartment via the ventilation system, when the solution is combined with district cooling, says Ronni Laaksonen, who is responsible for Enervent Zehnder’s sales.

– Depending on the size of the apartments and the air volume needed, Pingvin XL, Pelican Z or Pegasos Z ventilation unit models have been selected for the most spacious apartments. In street-level commercial premises, ventilation is provided by Enervent Pallas, which has a larger capacity.

Descendants know the architect Waldemar Aspelin, who designed the building at the time, as a stylist. In honour of its 125th anniversary in 2021, Bulevardi 14 will return to its original use. It will once again become an impressive residential building in one of Helsinki’s most important blocks.
