New ventilation system cut energy consumption in half
After the Instalco company, Aircano, replaced the ventilation systems at two properties in Hagsätra, Stockholm, energy consumption was cut in half.
“We put a great deal of focus on increasing the energy efficiency of our property holdings so that we can lower our climate impact,” says Erik Ollman at IKANO Bostad AB.
The properties called Långskylen 5 and 9 at Hagsätra were built in the 1980s and there are 190 apartments contained within the two buildings. Aircano was contracted for project planning and installation of new ventilation systems in conjunction with renovation of the properties. The aim was to achieve a profitable solution for the property owner, while improving the indoor climate for residents.
“Uneven ventilation flows and heat at the buildings was consuming a lot of energy. The indoor climate for tenants was not optimal either. We installed the most modern system for the purpose. It is a system with 12 FTX aggregates offering energyefficient recycling with reverse flow heat exchangers and energy-saving fans. The results are amazing,” says Tobias Eriksson, Business Area Manager for Instalco East.
In conjunction with the project, two new, complete district heating substations with modern control systems were installed.
“Creating future sustainable cities is an important goal for us and lowering our climate impact is one of our most prioritised areas. Aircano’s project planning and installation work at Långskylen cut electricity consumption by nearly 50 percent. The heat savings have also been significant,” says Erik Ollman, Energy Controller at Ikano Bostad.
