Antilooppi property Siltasaari 10 receives highest LEED certification rating in Finland

LEED is the world’s most widely used green building rating system. Achieving the highest Platinum rating reflects the first-class environmental responsibility and performance of the entire property.

The Siltasaari 10 property in Hakaniemi owned by real estate investment company Antilooppi has been granted the LEED Platinum environmental certificate. The property’s LEED (Leadership in Energy and Environmental Design) score of 85/110 is the highest achieved by a construction project in Finland, according to the current LEED v4 certification. The global LEED certification comprehensively covers responsibility and sustainability solutions.

“We were initially aiming for Gold level, but we soon realised that we have a chance to reach Platinum, so we raised the bar even further,” says Asset Manager Tuomas Hulkkonen.

For property users, the LEED Platinum level of Siltasaari 10 can be seen, for example, in terms of great accessibility thanks to its prime location and excellent social facilities. One of the central themes of the design was to guarantee cyclists at least as good an experience as drivers, so the property has a parking garage for 400 bicycles and even a bicycle repair station. Siltasaari 10 also has a digital heating and ventilation system, as well as a high level of overall energy efficiency. In addition, the property received almost full marks for indoor air quality.

“Siltasaari 10 is a historic property that we were able to bring right up to date with a complete renovation while respecting its history. Responsibility is evident in everything from the quality of the indoor air, water consumption and low-emission materials used in construction. The conditions for users are excellent, and the wellbeing of our clients has played a key role in the design and implementation of Siltasaari 10. To back this up, we are also obtaining WELL certification for the site,” says Hulkkonen.


Aiming for 100% certification by 2023

The real estate investment sector plays a significant role in climate change, with construction and buildings accounting for 40 percent of global climate emissions. Environmental responsibility is also an increasingly important theme for Antilooppi and its customers, and well-established certification allows for an objective assessment of a property’s responsibility. Of the total floorspace of Antilooppi’s property portfolio, 30 percent is now certified. Antilooppi has a total of nine LEED or BREEAM certified properties, and several new certification projects are currently underway. Antilooppi’s goal is to achieve 100-percent certification of its portfolio by 2023.

“The Platinum-level certification of Siltasaari 10 is a fantastic achievement and an excellent demonstration of the systematic and high quality sustainability work that has been put into this historic property. Sustainability has been developed in all areas and by listening to our customers. Sustainability is a strategic priority for Antilooppi and one of our core values. LEED is an excellent tool supporting our strategy as it advances both the carbon neutrality and wellbeing, which are the priorities of our sustainability strategy. Our goal is to provide working environments that support the wellbeing and productive work of our customers, while taking into account climate targets,” says Hannamari Koivula, Head of Sustainability and Property Management.

Antilooppi is committed to promoting the UN’s Sustainable Development Goals. The company has signed the Net Zero Carbon Buildings Commitment for the global real estate sector and committed to achieving carbon neutrality for its own energy procurement and construction by 2030. Antilooppi is also a member of the Green Building Council Finland Association, a non-profit association for the sustainable development of the building and construction industry.
