One of Europe's largest shopping centres, the Dolce Vita Tejo in Portugal, will utilise Uponor's underfloor radiant cooling technology. The 423,000 square-metre shopping centre, to be completed in the vicinity of Lisbon in May 2009, will house 300 shops and 9,000 parking spaces. The constructor of Dolce Vita Tejo, the Spanish real estate development company Chamartin Inmobiliaria, is investing in solutions complying with sustainable development principles, influencing energy efficiency and the consumption of primary energy in particular, both via architectural and technical solutions.

The shopping centre will utilise natural light actively: the roof of the building will be constructed of material that filters the sun's ultraviolet light, but retains the sun's brightness, enabling the reduction of electricity-consuming illumination. The warming effects of solar light will be compensated for using Uponor's underfloor radiant cooling. In a vast space, indoor climate would normally be difficult to manage with a traditional air-conditioning system. However, since the cooling radiates via the floor, pleasant temperatures can be maintained in the very space where people move, i.e. up to a height of approximately 2.5 metres. The floor temperature will remain at approximately 19-20 degrees Celsius at all times. According to the company’s press release, Uponor's underfloor cooling system will help achieve considerable savings in energy consumption.
