Varso Tower is the largest building in Europe with the WELL Gold certificate

November 21, 2023

The Warsaw skyscraper developed by HB Reavis received the prestigious WELL Core & Shell certificate. This innovative system uses knowledge from scientific research and confirms that Varso Tower meets standards for healthy construction. A Gold rating means that the building was designed with care for the people working in it, their comfort and safety.

WELL is a science-based standard by the International WELL Building Institute. It takes into account over 100 building parameters that affect people's health and physical and mental well-being. Issues related to access to fresh air, water quality, lighting, acoustics, thermal comfort and sanitary safety are examined. The assessment is carried out by independent auditors who verify the design, documentation and actual functioning of the building.

Among the appreciated solutions implemented in Varso Tower is an HVAC system that provides offices with much more fresh air than required by standards. Adiabatic humidifiers ensure health-appropriate humidity. Modern filters stop pollutants and harmful PM10 and PM2.5 dust, as well as allergy-causing pollen and fungal spores. Office workers have access to natural light most of the year because three-quarters of each floor is less than 7 meters from a window.

We received the final WELL certificate for Varso Tower with great satisfaction.

Research shows that buildings designed in accordance with this standard reduce many ailments, such as headaches, fatigue and breathing problems. They also promote faster regeneration, facilitate focus, stimulate creativity and reduce stress levels. This is yet another example that our offices in Varso Tower provide excellent working conditions and are in line with the latest ESG trends

says Cezary Błaszczyk, commercial director at HB Reavis Investments.

HB Reavis was supported by Hans van de Sanden in the certification process. In addition to WELL, the skyscraper also has other certificates, such as BREEAM at "Outstanding" level confirming low energy demand, WELL Health-Safety Rating and the inclusivity-focused Building without Barriers.
