Building 21 Milano

The building 21, has been designed by John Bonicalzi to host the Institute of Chemistry and Chemical Physics, and is currently occupied by classrooms, research labs, and departmental offices. Built in the early '70s, the facade chosen for the realization of the test corresponds to the west façade and it is characterized by the almost total absence of openings and by a coating of little value, since it was initially conceived as a temporary tamponade waiting for a future expansion ever made on an area currently used as a garden.

  • Objective
    Assessing the in situ thermal performance of the external insulation panel (WP2), together with the installation procedure and the proposed anchoring system, on an existing wall, representative of traditional construction solutions.
  • Description
    Building 21 is located in the "Città Studi" campus of Politecnico di Milano. It was built at the beginning of the 70's after a project by Giovanni Bonicalzi. The structure of the building is a prefabricated reinforced concrete frame, finished with precast concrete panels.
    The building currently houses offices for some departments of Politecnico.
  • Retrofitting intervention
    The test panels will be assembled on one of the West walls of the building. The external wall is in monolithic concrete, with a rough render finish outside and a drywall panel inside. The wall is not insulated. Behind the test area there are individual offices.
  • Activities description
    Installation of sensors and thermocouples for measuring the heat flow as well as the surface temperatures (indoor and outdoor) of the EASEE proposed solutions for WP2. Later installation of outdoor insulation panels and operative testing of anchoring and assembly procedures.
