SGS is proud to announce the completion of Flexolution – the first portable, reusable and sustainable test lab in the world. The project was an initiative of the S-Built Foundation. This is the first collaboration between the S-Built Foundation, Neptunus, and SGS.

The modular building is located in the German-Dutch business park Avantis, in Heerlen. It will serve as a facility for research, testing and demonstrations.

Rico van Selst of SGS INTRON says, "SGS will co-use this unique facility for testing and demonstrations with flexible test equipment. We are focusing on the testing, monitoring and certification of sustainable materials and building management systems. This allows us to respond to the trend of increased life expectancy and its demands with the multifunctional and sustainable use of buildings."

He continues, "Neptunus has completely fulfilled our expectations for the quick delivery of Flexolution, according to the schedule set by SGS. We are pleased that the building design has been completed, so that we can be operational in a short time. The building even contains reused parts of structures from the Olympic Games in London in 2012, a demonstration of the impressive capabilities of sustainable material use."

Flexolution portable test lab will be used for research, testing and demonstrations.

Dorrie Eilers of Neptunus adds, "We are pleased with our collaboration with the S-Built Foundation and SGS, which went smoothly. Our reusable buildings are indistinguishable from fixed, permanent structures, in terms of appearance as well as static and thermal properties. Their big advantage is that a full fledged turnkey property can be constructed in a few weeks, and then disassembled and completely reused later. This reusable building lives up to the standards of the building code and has achieved an A level energy rating. Our buildings are not only repositionable and reusable, they are made of entirely recyclable material. They are energy efficient, durable and extremely flexible."

For the next two years, Neptunus and SGS will continue to work together to develop reusable and rentable components and systems, to create the world's most sustainable structures.

Dorrie Eilers, Neptunus:

"Our buildings are not only repositionable and reusable, they are made of entirely recyclable material."
