The project, which began in the fall of 2025, is led by Frode Alm, project manager at Randem & Hübert. The building was approximately 15–20 years old and in need of technical upgrades as part of a comprehensive renovation. A key focus was to improve the indoor climate and adapt the ventilation system to meet current standards, without replacing the existing equipment with entirely new products.
“In terms of cost, reuse and new installations are relatively comparable, but the major benefit lies in the fact that we reduce the need for new purchases and use existing resources more efficiently,” says Frode Alm.
Randem & Hübert is responsible for a comprehensive retrofit solution in which a total of 167 air handling units have been upgraded with new control and regulation technology. This enables individual control of temperature and ventilation, as well as improved monitoring of operations.
“By upgrading existing air handling units instead of buying new ones, we can keep products that still work while achieving the same technical level as modern systems,” says Frode Alm.
The technical upgrade means that the property now has a modernized ventilation system that contributes to a better indoor climate and more efficient energy use. By controlling ventilation and climate based on actual use of the premises, the project creates the conditions for lower energy consumption while improving comfort for tenants. The project on Wergelandsveien is also one of the first in Norway where ventilation units have been upgraded on this scale.
“We’re proud to be among the first to implement this type of large-scale upgrade. It shows that it’s possible to combine reuse with modern functionality and efficient operations,” concludes Frode Alm.
