The foreseen tasks and objectives have been fulfilled for each WP
WP1 developed a model to predict internal microclimates of enclosures, and an app (

A damage function for PVC was developed and integrated in the DSS; changes of properties of Poly(methyl methacrylate) were monitored vs. humidity. The most promising absorbers developed in WP3 were validated in complete boxes
WP2 used multiscale coarse-grained and continuum models to study the absorption/desorption dynamics of VOCs into acrylics, with quantitative information on structural changes. The VOCs flow in the room and deposition on artworks was also modeled. The APACHE APP combines the mesoscopic and continuum model, using the SimPhoNy CUDS data structures. Machine learning models applied to paper enclosures were produced, based on the XGBoost algorithm to predict T and RH in enclosures
WP3 produced a set of absorbers against VOCs typically found in museums, providing candidates to replace benchmark absorbers in terms of cost-effectiveness. Examples include castor oil based hybrid inorganic-organic composites, chitosan or graphene-based aerogels, cross linked resins, Poly(vinyl alcohol) membranes, polymer-silica composites in cellulose foams. They were tested in laboratory and in museums, and integrated in archive/deposit boxes
WP4 developed: sensor front end solutions for RH, T and VOC; short range communication solutions; long range Lorawann or Bluetooth solutions for museum interiors; application server and smartphone applications developed for short range sensors
WP5 produced and tested a repository for preventive conservation measures, demonstrated in two APACHE training workshops, with positive feedback from end-users. The APACHE DSS software was also completed and released
WP6: the project has produced patents and trademarks, and some of the best systems are ready for introduction in the market. A spin-off company (Adsorbi) has been created to distribute absorbers even beyond the CH conservation market. Prototypes of display cases were implemented with philtering systems, passive absorbers and sensors. LCA and LCC applications were carried out for the best systems developed by the project
WP7 has carried out intensive dissemination of the project results in more than 70 events in Europe and worldwide, despite the difficulties due to the Covid-19 pandemic These included public trainings, workshops, a symposium, and the APACHE School, including end-users external to the project, and clustering with other H2020 projects on the same topics. APACHE also participated to events organized by the European CH cluster ECHOES. The project produced 26 publications, and ca. 10 more are in preparation. The project website and social Media activity were updated regularly
