Greenspace PCTG: a self-sufficient office space

Greenspace PCTG is a near-zero energy office building inaugurated by Gesyges Innovación en la Edificación SL, located in the Parque Científico Tecnológico de Gijón.

With Gijón Impulsa as tenants, the building is occupied by startups and companies committed to innovation and digitalisation.

The bioclimatic building, whose conception began in 2014 under the LIFE programme of the European Union, has a total built area of 1,200 m² distributed in basement, ground floor, two upper floors and a roof level. 

Arup guided the owners of the building towards a Net Zero concept incorporating measures such as the generation of renewable energies for self-consumption and export of surpluses to the electricity grid.

Project Summary

1,200m2 office space



Energy self-sufficiency

From the beginning of the project, Arup advised the design team and the owner on the strategy required to obtain a building that can self-generate all its operational energy, in accordance with the criteria set out in the European directive on the energy efficiency of buildings.

The innovation and efficiency of the building’s installations reduce energy demand to a minimum. The building has a thermo-activated slab powered by high-efficiency heat pumps and chilled water circuits installed in the cores of the slab, allowing it to be consistently tempered and offering a comfortable temperature all year round. Among other multiple solutions, this unique space will have solar protection on the south façade to prevent thermal loads in summer by means of a large photovoltaic pergola, allowing the building's renewable energy to be self-generated.

Both in the bioclimatic design consultancy and in the zero-energy building concept, we have prioritised locally appropriate solutions in combination with innovative, efficient and renewable technologies. We are proud to be able to participate with this exemplary project in the decarbonisation of the building sector. ” Ramon Rodriguez Ramón Rodríguez Spain Group Leader

In addition to energy consulting on the design, Arup has also been the sustainability consultant under the LEED certification criteria to achieve Gold level. Other sustainability criteria for the building include LED lighting with daylighting sensors from north facades, user comfort with natural ventilation, integrated water cycle management control and the installation of a rainwater recycling tank for use in toilets and irrigation.
