Porous materials to control climate behaviour of enclosures: an application to the study of screened greenhouses

The aim of this paper was to study the influence of porous materials (screens, shelters, filters, etc.) on the climate behaviour of enclosures. First, a theoretical approach, describing the climate behaviour of a multi-zone enclosure, was proposed, being afterwards validated against experimental data. Having obtained a satisfactory agreement between the theoretical predictions and the experimental data, applications related with the use of porous screens in greenhouses were researched. This research concerned screened greenhouses, but other aspects, such as indoor climate control in buildings with ventilation filters, can greatly benefit from the approach presented in this paper.
