Läckö Castle is an historic building that has never been permanently heated but has been dehumidifiedsince the early 2000s to house museum collections. The purpose of the work was to evaluate thedehumidification performance and compare the climate with the state of preservation of wooden wallpaintings. Compiled climate recordings for different rooms in the castle from 1997 to 2009, before andduring dehumidification, were used and compared to the outside climate. The RH set point value of 70 % for dehumidification was not reached often, especially in winter with high outside RH. Wood painted witha linseed oil paint performed well, whereas paint containing resin was seriously damaged. It is concludedthat microclimatic differences in relation to dominating wind direction are important. The air exchangeof the building is very decisive for dehumidification efficiency.

L’objectif de notre recherche consiste à caractériser le concept de plissage afin de proposer un modèle numérique permettant de concevoir des structures architecturales plissées en panneaux de bois. Dans ce contexte, nous ouvrons une perspective originale sur l’intégration de la dimension morpho-structurale comme facteur de modulation de l’architecture. Nous abordons également le plissage dans sa dimension numérique par une approche paramétrique. Cette dernière permet une modélisation adaptative dans le continuum conception-fabrication. Notre méthode, implémentée dans l’outil CARA(s)PACE (Conception of Architectural Research Algorithm for Structural Pleated Approaches and Creative Envelopes), permet de générer une géométrie de plissage à partir d’une surface de référence. Cet outil est composé d’un modeleur géométrique paramétrique couplé à des moteurs d’évaluation. Il guide le concepteur dans la recherche de formes fondées sur le plissage, sécurise les propositions et fournit les données numériques nécessaires pour une fabrication robotisée / The purpose of this research is to characterise the concept of pleating in order to give a numerical model allowing the design of wooden pleated architectural structures. In this context, we are bringing a singular perspective to the integration of the morpho-structural dimension as a modulating factor of architecture. We also deal with creasing in its digital dimension by adopting a parametric approach which allows an adaptive modelling within the ‘design-manufacturing’ continuum. Our method, implemented in the CARA(s)PACE (Conception of Architectural Research Algorithm for Structural Pleated Approaches and Creative Envelopes) tool, generates a geometry of pleating from a reference surface. This tool is composed of a parametric and geometric modeller coupled with evaluation engines. It guides the designer in the research of forms based on creasing, secures the suggestions and provides the numerical data needed for a robotic manufacturing
