Abstract

[en] This Master's thesis concerns the assessment of the effect of passive green walls on indoor air
quality in terms of VOCs by means of punctual (Tenax®TA) and continuous (Radiello®) sampling
in the context of the “Green4Indoor Wallonia” project.
The tests were conducted in an office sized, temperature controlled chamber submitted to
climatic sequences simulated in a buffer zone in order to replicate exterior temperature
fluctuations in summer and winter. The composition and concentrations of VOCs inside the
chamber were assessed in empty chamber tests, tests with an added VOC source (painted
gypsum board), and tests with green walls plus an added VOC source, all according to the
various climatic simulations. The samples were analyzed by TD-GCMS and results were
assessed through visual inspection of data by means of graphical representations.
The results show that tests with green walls during winter simulations present lower VOC
concentrations than tests without green walls irrespective of sampling methods. For summer
simulation tests with green walls, Tenax®TA results also present lower VOC concentrations
whereas Radiello® results present higher VOC concentrations when compared to tests without
green walls. Given the multitude of constraints, confounding factors and problems
encountered, the exact cause behind the discrepancies cannot be determined. The limitations
and shortcomings of the experimental methodology were also discussed in order to propose
improvements for potential future experiments involving green walls.
