State Hermitage, St. Petersburg

Swegon supplied 15 air handling units to the State Hermitage in St. Petersburg, Russia and created a perfectly balanced indoor climate for the enormous art collection in the Russian winter palace.


The Russian Winter Palace was designed by the architect Bartolomeo Rastrelli in 1732 and ventilated by a combination of 1,500 chimneys and natural draughts through the windows. In those days the building was the residence of the ruling Russian tsars. Nowadays the palace is part of the State Herimitage museum and houses one of the world’s largest art collections, including works by da Vinci, Rafael, Monet and Rembrandt. Following a fire, almost all the old chimneys stopped working, and as the old windows were replaced, the natural ventilation gradually dwindled. Paintings, tapestries and fragile materials all began to suffer from the trapped moisture. Mechanical ventilation became a necessity and Swegon created a perfectly balanced indoor climate with 15 discreet air handling units.
