Within the PM&VL6, the impact of the different multilayer dry building envelope systems on the overall acoustic performance is monitored through a dedicated sound meter.
Objective
The objective of the proposed acoustic tests is to assess the impact of different envelope solutions and components on the overall performance in the respective space of installation.
Scope of application
Generally speaking, the proposed tests are applicable to any enclosed space. Although, considering that dry-layered envelope solutions are made of several different functional layers, it goes without saying that the various products installed will all have an impact on the overall airtightness of the space. Hence, in order to have more accurate and relevant impact assessment, it is recommended to install full-scale solutions or to apply products and components as diffusely as possible.
Design of experiment
The activity will be planned according to the needs of the client.
Testing sample
Full-scale, to be furtherly specified according to the relevant envelope component (e.g., wall, roof, door, window, roof window) and to the respective installation method. For example, as refers to opaque components, the BEEpilot prototype fits:
(i) full-scale façades with a total width of 2.5 m, and a total height of 3.0 m;
(ii) full-scale roofs with a total width of 2.315 m, and a total height of 2.76 m.
General characteristics
A preliminary assessment (e.g., typology and positioning of connections and joints, overall weight) is required for a proper installation of any mockup on the existing structure/substrate of the prototype.
Outputs
The documentation that the client receives consists of a report with details, observations, pictures, test schemes and test results.
