Ericusspitze Spiegelhaus, Hamburg, Germany
Det nya huvudkontoret för Spiegel Group ligger i Ericusspitze i Hamburg, Tyskland. Det termiskt aktiva betongbjälklaget från Uponor garanterar en behaglig temperatur i byggnaden alla tider på dygnet.
Grunduppvärmning och kylning av den nya byggnaden sker med Uponor Contec bjälklag. Cirka 8150 kvadratmeter takyta förseddes med prefabricerade Uponor Contec bjälklagsmoduler. Modulerna har integrerade PEX-rör (PE-Xa, tvärbunden polyeten) med dimensionen 20 x 2,3 mm.

The remaining heating and cooling loads are covered using suspended ceiling panels that are also thermally active. The loads still remaining for climate control are covered using a heating-cooling panel, and in areas with increased cooling requirement, using a conventional air conditioning system. For heating, the energy retrieved from the geothermal system is sufficient to cover the base loads using the concrete core activation as well as the ceiling panels with an intake temperature of 35°C and a return temperature of 30°C. To address demand peaks in secondary areas of the building and for additional heating, district heating is used according to the prevailing demand.
"In addition to a geothermal system, when planning the surface temperature control in the floor and ceiling, the use of district heating was also taken into account in the energy concept", explained Ralph Valtinke, specialist planner at DS-Plan Ingenieurgesellschaft für ganzheitliche Bauberatung und Generalfachplanung mbH.
When it comes to cooling, higher thermal power is required to supply the cooling panels. To achieve this, the cooling circuits of the concrete core activation used here are set up as separate cooling circuits. External protection against the sun as well as back cooling of the double facade are employed so that the new Spiegel building is protected against excessive temperature rises.
A bivalent surface temperature control in the ground floor is integrated in the energy concept. The well-proven Uponor Classic support element system ensures uniform heating and cooling. When heating, an intake temperature of 40°C with a return of 30°C is planned and for cooling an intake temperature of 18°C with a return of 21°C. With this overall energy concept the basis has been created to be awarded the "Gold"-Status for the new Spiegel building at the Ericusspitze. With the overall concept, the annual primary energy demand of the building is below 100 Kilowatt hours per m².
The Uponor Quick & Easy system components were used for the 3,000 metres of connecting pipes. This type of installation decreases time-consuming pressing, welding or soldering. After a locking ring has been placed over the pipe, the PE-Xa pipe is expanded using an expansion tool and then inserted in the fitting. As a result of the memory effect of the material, when the pipe shrinks, the it is firmly connected to the fitting.
Varicool heating and cooling panels were installed to the meeting room's ceiling. The new hydronic system replaced the old fan coil unit system. Varicool system is a radiant heating and cooling system. The panels do not heat or cool the indoor air directly but the surfaces what radiant covers.
Thermal concrete core activation with Uponor Contec provides economical, energy-efficient and sustainable building temperature control in the new landmark Adlershof Science and Technology Centre.
A hygienically optimal drinking water installation was integrated into the new office complex – thanks to Uni Pipe PLUS within a very short time.
La dalle active Uponor est intégrée depuis 2017 dans l’immeuble Delta Green, bâtiment tertiaire de 4600m2 comprenant 4 niveaux. Celui-ci est le premier bâtiment de la région tout à fait autonome en énergie.

Uponor were nominated as the sole supplier for radiant heating systems for the Sunesis Schools schemes, with Main Contractor Willmott Dixon. Sunesis is a Joint Venture between Scape and Willmott Dixon, built on the combined experience of public sector know-how and private expertise. They are the market leader in delivering pre-designed buildings across a range of market sectors. Every design has a defined layout, specification, fixed cost and timescale to construct. The full benefits of a full BIM model are also utilised.
Le bâtiment d’enseignement supérieur et de recherche pour l’Institut Mines-Télécom intègre un système de dalle active sur une surface de 40 000 m2. Le bâtiment économe en énergie accueillera une gamme variée d’activités propres à l’Institut Mines - Télécom : formations, recherches, transfert et innovation.
