The building was completely refurbished and optimised to fit the requirements in innovation, sustainability and design. The project achieved the A Energy Performance Certificate as well as the LEED Gold rating. To optimise the buildings energy consumption a pioneering and exclusive air-conditioning system was created. This system uses water and gas as transmission fluids for an optimised performance, efficiency and sustainability. The striking double skin façade on the four sides of the building is built up out of a curtain wall solution in combination with micro perforated stainless steel sheets. This allows sunlight to come through while offering acoustic insulation. To optimise the buildings energy consumption a pioneering and exclusive air-conditioning system was created. This system uses water and gas as transmission fluids for an optimised performance, efficiency and sustainability. The striking double skin façade on the four sides of the building is built up out of a curtain wall solution in combination with micro perforated stainless steel sheets alternating with glass panels. This allows sunlight to come through while offering acoustic insulation. ### Used systems [Façades](/products/facades) - [ConceptWall 50](/products/facades/conceptwall-50) [Doors](/products/doors) - ConceptSystem 68 ### Involved stakeholders Architect - [Rafael de la-Hoz](http://www.rafaeldelahoz.com/) Photographer - Alfonso Quiroga Ferro Share this case study - [f](https://www.facebook.com/sharer/sharer.php?u=https%3A//www.reynaers.co.za/markdownify/node/6128%3Futm_source%3Dfacebook%26utm_medium%3Dsocial%26utm_campaign%3Dwebsite) - [t](https://twitter.com/intent/tweet?text=https%3A//www.reynaers.co.za/markdownify/node/6128%3Futm_source%3Dtwitter%26utm_medium%3Dsocial%26utm_campaign%3Dwebsite) - [l](https://www.linkedin.com/shareArticle?mini=1&url=https%3A//www.reynaers.co.za/markdownify/node/6128%3Futm_source%3Dlinkedin%26utm_medium%3Dsocial%26utm_campaign%3Dwebsite) - [p](https://pinterest.com/pin/create/button/) - [m]() ## You might also like [ See all projects ](/projects) - ![XS 68 Windows, CW 65-EF Façades, ConceptSystem 77 Windows and CW 50-SC Façades - Etopia Centre for Art and Technology located in Zaragosa, Spain](/sites/default/files/public/styles/teaser_medium/public/inriver/73827_Etopia%20Centre%20for%20Art%20and%20Technology8.jpg?h=4c5f9b83&itok=-_nW_Pf4) ### Etopia Centre for Art and Technology *Zaragosa - Spain* [Learn more](/inspiration/aluminium-project-references/windows-facades-etopia-centre-art-and-technology-zaragosa) - ![ConceptWall 50 Façades and BriseSoleil 100 Solar Shading - Teatro municipal núria espert located in Sant Andreu de la Barca, Spain](/sites/default/files/public/styles/teaser_medium/public/inriver/80089_REYN-4590.jpg?h=d73728dc&itok=ZjcuHzv8) ### Teatro municipal núria espert *Sant Andreu de la Barca - Spain* [Learn more](/inspiration/aluminium-project-references/facades-solar-shading-teatro-municipal-nuria-espert-sant-andreu-de-la-barca) [ See all projects ](/projects)
