Tower blocks in Herttoniemi
As Oy Helsingin Poudantuoja
The new residential building, built on top of the shopping centre Herts, was completed in spring 2021. The site is a high-rise building with a total of 130 apartments and 18 floors from the deck level. The site is part of a hybrid complex comprising the shopping centre itself, a kindergarten, a library, a care home and two other residential blocks. Hepacon was the HVAC and electrical designer for the project.
In the HVAC design, the pressure management of the pipelines associated with the high construction height was solved by dividing the networks into several sections. This achieved water sufficiency and water pressure resistance in the pipelines. The site was designed with apartment-specific IV units and the façade takes into account separate wall ventilation requirements for supply and exhaust air. Ventilation of the common areas is provided by separate heat recovery ventilation units. The chimney effect in the common areas was also an important design consideration.
