Want to help out the ATLAS project?

In order to avoid structural damage and ensure building’s performance, applicability of retrofit solutions strongly relies on the understanding of their hygrothermal behaviour. Based on laboratory tests and numerical calculations, ATLAS researchers will develop performance coefficients (e.g. drying coefficient) that leads to the prescription of the most adequate retrofit solutions.

What do we need for this activity?
For the definition of these coefficient, we need to gather “real on-site” data of the hygrothermal of historic walls before any renovation has taken place. Therefore, we are looking for old buildings (ideally not renovated) that were built with traditional materials and still have the original plaster.

What will be done?
Researchers will carry out a number of test with the permission of the building owners. Among those:

  • Water adsorption measurement: application of an apparatus externally that wets the wall and measures how much of the water goes into the wall (simulation of a rain event). Duration 1-2 hours and no damage to the wall.
  • Air tightness measurement: application of an apparatus externally that creates an overpressure to measures how much air goes across the wall. Duration 1-2 hours and no damage to the wall.
  • Heat conductivity measurement: application of a 30x30 plate to the wall internally and of 4 surface temperature sensors (2 inside, 2 outside). Everything is fixed with tape to the wall (shouldn’t cause any damage). Duration 2 weeks in winter.
  • Sample removal: if the building owner is ok with it, we will take plaster samples (minimum 20 x 20 cm) for laboratory measurements.
