Zero emissions, maximum comfort
Greenspace PCTG in Asturias, Spain, is the first net-zero energy office building in the region and one of the few of its kind in the whole country. An impressive achievement made possible by a combination of highly efficient active energy and passive systems. Spanish architects EMASE Arquitectura worked with engineering firm SvR Ingenieros to create a sustainable, environmentally friendly design. It uses solar panels for keeping solar loads out of the building on one hand and to generate more energy than the building consumes on the other hand. In order to minimise the building’s energy use, the project partners turned to Uponor and its thermally active building systems (TABS) for heating and cooling.
Between the basement, the three above-ground floors and the roof, Greenspace covers a total area of 1,500 square metres. Since it was opened in Gijón Technology Park in July 2020, it has hosted a range of start-ups and other companies with a focus on innovation and digital technology.
Minimising energy consumptionGreenspace has a positive energy balance: this means the building generates more power than it uses thanks to extremely efficient active and passive energy systems. The passive systems include, for example, insulation or natural lighting. The active systems involve the solar panels, the indoor climate solutions through the TABS and the radiant floor heating, as well as the monitoring and control of the building services.
Uponor provided the thermally active building system (TABS) which makes use of the thermal inertia of the building’s concrete structures. A network of 7,500 metres of Uponor Comfort Pipe PLUS was built into the structure of the building, using concrete core activation to store and release both heat and cold. The pipes carry water for the building’s heating and cooling systems and provide comfortable temperatures all year round. With the HEAT2 simulation software from Uponor, the project partners in Gijón were able to analyse the building’s static and dynamic thermal behaviour over time. This was the key to finding out the best way to use TABS.
Internationally certifiedThe energy concept includes much more, for example 134 solar panels, a lift that uses the energy of this panels or low-energy LED bulbs, controlled by intelligent sensors. The result of all these measures: a very pleasant working environment fostering creative thinking and high productivity. The range of energy efficiency and bioclimatic design measures employed, together with the use of renewable energy, healthy architecture, and low-emission materials, has seen Greenspace earn gold certification from LEED. This certification places Greenspace among the most sustainable buildings in the world.
“We needed a heating and cooling system that was tailored to the building structure while also being energy-efficient enough to fit in with our energy calculations and hydraulic design requirements,” says Ramón van Riet from SvR Ingenieros.
"With the support of Uponor's technology, EMASE Arquitectura and SvR Ingenieros were able to determine the ideal size for the solar panels and enery distributions systems." Ramón van Riet, SvR Ingenieros.
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.
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.
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.

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.
