Forest based composites for façades and interior partitions to improve indoor air quality in new builds and restoration

Tendering Process for Demo Building Construction has been Launched

The verification of the performance of OSIRYS products in a real demo building is a key part of the project, as a basis for replication in future projects. VISESA, Basque Government’s Public Housing body, is providing a typical social housing block as a demo that could represent the average housing standard in the country. In this demo building, the OSIRYS products will be installed in one of the apartments, substituting the standard products used in the façade and internal partitions by the developed bio-based products.

The housing block for the OSIRYS demo is located in the Morlans neighborhood, in a central district of Donostia-San Sebastian. The building is a rectangular shaped housing block, 7 stories high and with 70 apartments. One corner apartment in the second floor, comprising two bedrooms, bathroom, kitchen and living room has been selected for the installation of OSIRYS products. Once the construction is finished, the monitoring activities will be carried out in this apartment and in another apartment with conventional products, in order to compare the air quality and the technical performance characteristics considered in the project.

The technical project development has been carried by Germán Velazquez architects, and the tendering process for the construction works was launched on the 22nd December 2015. The tender documents including the particularities of OSIRYS demo apartment are published at

Construction companies are now expected to participate in the tendering process with their bids, and taking into account the characteristics of the OSIRYS demo.
