The Circle certified as Switzerland's best LEED building

International recognition for sustainability

LEED® stands for "Leadership in Energy and Environmental Design" and is one of the world's leading sustainability labels for buildings. It aims to promote healthy, durable, affordable and environmentally sound construction. The LEED label is awarded based on credit points. The Circle received 93 out of a possible 110 points, making it LEED Platinum certified, which is the highest possible rating. This is the highest score ever received by a LEED Platinum certified building in Switzerland. Both in Switzerland and in Europe, the Circle is also the largest building complex with this certification.

Minergie standard thanks to renewable energies

In addition to LEED, the Circle is also Minergie certified. This voluntary standard designates and qualifies buildings that meet specific requirements in terms of permissible energy demand. The Circle is characterized by a number of sustainability aspects. The decisive factors for the Minergie certification of the Circle included the above-average energy efficiency and the high proportion of renewable energy via geothermal energy piles and photovoltaics. The entire Circle manages almost entirely without fossil fuels.

Environmentally compatible construction

Property alterations and new-builds are crucial to the development of the airport. Old infrastructure needs to be updated so that it continues to meet the contemporary requirements of use, management and environmental protection. Construction projects therefore receive environmental construction support and are assessed with regard to their ecological impact during the realization phase as well as later use. Thus, LEED certification is also being sought for the next major construction project, the new Dock A with tower and dock base. The new Dock A is to be built largely from sustainable wood on the passenger levels - this is so far unique for a terminal building of this size.
