WELL certifies that property conditions support wellbeing

The Siltasaari 10 property in Hakaniemi, Helsinki is a historic building. It represents the cutting edge in wellbeing.

WELL v2 evaluates the property using ten concepts. They include air, water, light, thermal comfort, materials and sound. The requirements also extend to healthy nourishment, physical activity, community, and spatial solutions and measures that support wellbeing.

Siltasaari 10 was fully refurbished in 2021 with full consideration for wellbeing throughout, from design to construction. The building uses low-emission materials. The property’s technical features, such as heating, lighting and indoor air, have been tuned to the highest standards. Automatic lighting control minimizes waste lighting. Economical water fixtures help reduce water consumption. An AI-based energy management system which automatically optimizes the performance of the heat, plumbing and ventilation systems’ performance supports the building technology. Antilooppi has also placed a particular emphasis on acoustics and sounds.

“The certification process guided us to make our building’s conditions even more functional. We see this, for example, in the comfort of the common areas and in working conditions, such as ergonomics. The best feedback is of course our satisfied clients, who highly appreciate the quality facilities and extensive services on offer at Siltasaari 10,” Hulkkonen says.

Physical wellbeing is also crucial at the property. The central location by the water in Hakaniemi encourages the use of green modes of transport. The building boasts a progressive 400-space bike park, equipped with e-bike charging stations. Shared bikes, high-quality common areas and encouragement to prefer stairs over lifts all support physical activity. This property is all about community. It offers a wealth of break rooms, restaurants, services and Antilooppi’s sustainable and flexible POOL spaces which support wellbeing.
