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

Sea water or breeze test is to determine the durability of the product performed by aging test caused by sea water or breeze. The innovative test procedure includes two aging methods:
1. For artificial aging in substitute ocean water, 18 immersion drying cycles are performed. Each cycle consists of 55 hours of immersion (a total of 1,000 hours in 18 cycles) and 112 hours of drying at 38°C (a total of 2,000 hours).
2. Immersion in alternative ocean water for 3000 h (Stefano De Santis, 2018).

Some of the highest thermal energy losses from a building are through its envelope systems and components. These thermal losses contribute significantly to the energy used by HVAC systems and, in turn, the energy bill and carbon footprint of the building. The best way to assess how well a building or solution is performing on the thermal point of view is a specifically studied combination of different activities, such as airtightness tests, and thermal, heat flux and hygrothermal monitoring.

Indoor Air Quality (IAQ) can be defined by the depiction of concentrations of pollutants and thermal conditions that may negatively affect the health, comfort, and performance of building's occupants. Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems and can include also building materials releasing pollutants more or less continuously.
