Indoor climate with a customised solution
A sustainable urban distric with a wonderful view
In addition to the 1,100 homes that will be built in the coming years, other amenities are also planned for in the neighbourhood, such as gyms, restaurants, grocery stores and smaller shops.
Sustainability is key in this development project and the propery owner, Bostads AB Vätterhem, emphasizes that it is sustainability seen from the perspecitives of cultural, social and ecological values for the residents. With that in mind, sculpture parks, recreation areas, solar panel-covered roofs, e-bike rentals and grow boxes are thought of in the project. With the lake right nearby, an open-air swimming-bath is also arranged for in this emerging urban district.

Custom designed cooker hoods and supply air diffusers
There were two main challenges in terms of ventilation in this project.
The customer requested a cooker hood with excellent ability to extract cooking odors at low flows, this in order to be able to utilise a constant flow ventilation for the entire building, and still achieve a balanced ventilation in the apartment. The building was pressure tested and had a leakage flow of 0.17l/s/m² enclosure area, meaning cooker hoods that force the air flow would not be a possibility.
In the same project, Vätterhem requested an aestheticly attractive supply air diffuser adapted to Ormhuset's architectural design.
Developments of Swegon DOMO and TANGO
Our Swegon CASA Tango cooker hood was developed, in collaboration with Vätterhem, to become a Free Flow product. The adjustments made to the product made it suitable for Vätterhem also in many other of their projects. It is used in new-builds as well as in renovation projects.
An example, about 200 apartments had an undersized duct system which caused limitations for forced flows in some of the apartments. The CASA Tango cooker hood suits these appartments very well.
In order to do a proportionate air adaptation, the Swegon DOMO supply air diffuser was improved. Today, it delivers what was expected in terms of air flow and does also correspond to the customer's requirements in terms of aesthetics and design.

Sustainability unknown to the tenants?
As said above, Swegon GOLD air handling units were chosen for this project. Also mentioned, they were provided with plate heat exchangers, highly advanced heat exchangers where the warm extract air is used to heat the colder supply air. Actually, vice versa is also possible which means that the heat exchanger can be used in an efficient manner to recover cooling energy too.
No matter if it is heat or cold, to recover energy is obviously a relief for the environment as less energy is needed to cool or heat the supply air and to keep the temperature indoors at a comfortable level. This might not be a measure for increased sustainability known to the tenants living in the building, but it is far from complicated and may very well be a key selling point.
