Deichman has 4 floors equipped with TABS - Thermal Active Building System. This is a cooling and heating concept where we store the energy in the concrete ceilings. New in Norway, but a proven concept in central parts of Europe. Uponor has designed and delivered equipment to more than 1,000 buildings with TABS since 1997.
TABS - Thermal Active Building Systems - is a principle for thermal activation of concrete ceilings. The surplus heat in the room is stored in the concrete layer, and extracted from the building via water-conducting pipes that are embedded in the concrete. The cooling capacity is 60 W / m2.
The room temperature will vary from a selected starting temperature, e.g. 20 degrees, in the morning and increase to a chosen maximum level, eg. 25 degrees - which often occurs towards the end of the workday. The circulation pump for the cooling water will then start. The two temperatures are chosen according to the building's application, and is optional.
In heating mode, the TABS ceilings can deliver 30 W / 2. Deichman is a so called passive energy house with a heat requirement of about 15 W / m2. The flow temperature of the circulation water regulates the effect.
