Rivergate, Wien, Austria
The Contec ON solution has replaced conventional displacement ventilation in the RIVERGATE building with a silent air-conditioning system. Contec ON modules were installed over an area of around 22,000 m². The advantages of Contec ON lie in the efficient use of geothermal energy. The system uses both a heating pump and cool groundwater. The frost-resistant glycol mixture in the Contec ON pipes is brought to a flow temperature of 14°C using a heat exchanger. The return flow temperature is 16°C. When combined with a heat pump to generate energy, groundwater covers cooling needs of 84 W/m².
The cost and comfort of the radiant heating and cooling system were also taken into account in addition to the energy savings and ecological efficiency on offer. The Contec ON pipe matrices were installed at a highly effective depth of 16 mm under the concrete undercover to facilitate the desired rapid responses to load fluctuations and to achieve the larger (relative to conventional thermally active building structures) energy spectrum required to heat and cool. The oxygen-tight and high-pressure cross-linked PE-Xa pipe in use has a nominal width of 14 mm x 2 mm. In addition to providing for cooling, Contec ON is able to meet the building’s heating load of 25 W/m².
The combination of the heat pump and renewable geothermal energy is energy-efficient and therefore cost-effective, using mild heat radiation with a low flow temperature of just 35°C and a return flow temperature of 25°C (four-conductor system). The RIVERGATE can also be heated using additional convector heaters to compensate for peak values during long periods of frost. The prefabricated Contec ON support modules were quickly mounted to the on-site ceiling formwork. The technicians appreciated the automatic spacers in the Contec ON modules. This feature allows the reinforcement to be laid directly on the modules. Thanks to proven Uponor pressing technology, the modules were reliably and securely connected to the distribution and collector pipes of the MLC composite pipe without any special tools.
A total of 50,000 metres of Uponor’s MLC composite pipe were laid to provide distribution pipes to connect the Contec ON modules in the ceilings from the first to the twelfth floor. The large dimension MLC composite pipe system offers the additional advantage of ergonomic installation. The system has a modular, flexible design, and no overhead work is required. Only 27 components are required for the installation. It is not necessary to use the reducer fittings required for conventional composite pipe systems.
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.
