From smart to climate smarter
A difficult and green challenge
The requirement was to make the building as versatile as possible. Room layouts, electricity and data were to be adapted for different types of business and to offer the tenants multiple options for arranging the office to suit their needs and wishes. The building also had to be extremely energy-efficient – climate-smart.
Unusual and unique solutions
The Waterfront Building shares its energy system with the hotel and congress centre in the Stockholm Waterfront complex.
250 tonnes of ice plus water from Lake Klara are used to regulate the temperature inside the buildings, both for heat dumping and also as a source of heat during the winter and free cooling when the water temperature is low enough. This technology is unique in the world.
The congress centre’s glass façade and double-glazed windows act not only as a soundproofing barrier but also as solar collectors, supplying power to the Stockholm Waterfront buildings. An average of 1 MW of thermal energy is collected by the 1,040 m2 of solar collectors every day. That is equivalent to 90,000 standard low-energy light bulbs.
