Hygrothermal optimization of buildings considering climate change

The hygrothermal behaviour of historic buildings that house artefacts can be studied through a non-destructive methodology, which enables to assess the impact of climate change in the indoor climate of buildings and, consequently, to find measures to mitigate its negative effects.

Coordinator: Guilherme B.A. Coelho

The non-destructive methodology has two phases: 1) in-situ monitoring, and 2) validated building simulation using whole-building hygrothermal software. The impact of climate change in the indoor climate of historic buildings can be determined and, consequently, measures that mitigate its negative effects can be optimized whilst taking into account the requirements for this type of buildings, i.e. artefacts’ conservation, occupants’ thermal comfort and building’s energy consumption.

The monitoring campaigns are based on the results obtained by using long-term and multi-sensor systems, which determine the indoor temperature and relative humidity of the case studies. These measurements are used to assess the indoor climate and to feed phase 2. The computational modelling of the case-studies allows to develop hygrothermal analyses, which use the measurements from phase 1 in its calibration procedure, to thoroughly analyse the proposed measures, thus choosing the most appropriate ones to minimize the effects of climate change in the indoor climate of the case studies.
