On June 4, 2015, the final Blower door test was carried out at the The Library of Villamediana de Iregua with a result of 0.40 h-¹, thus improving the result obtained during the construction phase in March. The test was carried out again by Energiehaus and the staff responsible for the construction company Harinsa Navasfalt, the managers of the companies Onhaus, which supplied the sealing material, and Carpintería LLodiana, which supplied and installed all the windows in the project, as well as the technical management of Play Arquitectura, attended the event. With this test, the construction phase is practically complete and we are entering the final stretch of the Passivhaus standard certification. 

From Play Arquitectura we would like to thank the companies Harinsa Navasfalt, Onhaus, Carpintería LLodiana and Energiehaus for the effort, dedication and professionalism shown from the very beginning to ensure that the demanding construction requirements of the Passivhaus standard were met in the first public building in Spain.
