Descrizione del progetto
Isolamenti ecocompatibili per conservare l’energia
I materiali di isolamento termico sono parte integrante degli involucri edilizi. Essi riducono il trasferimento di calore e ottimizzano il comfort termico interno. Il progetto NRG-STORAGE, finanziato dall’UE, si propone di lanciare un nuovo innovativo sistema di isolamento che sostituisce i materiali isolanti disponibili con una schiuma cementizia multifunzionale ad accumulo di energia e risparmio energetico (NRG-Foam). Questa schiuma a porosità ultraelevata mostra eccellenti proprietà isolanti incorporando cambiamento di fase e nanomateriali. Per di più, lo strato di NRG-Foam sarà caratterizzato da una maggiore tenuta all’acqua e all’aria, raggiungendo un miglioramento di almeno il 25 % della capacità di isolamento. Sarà inoltre almeno il 15 % più economico rispetto alle soluzioni attualmente disponibili in Europa.
Obiettivo
The NRG-STORAGE project will launch a novel breakthrough solution that replaces the currently available insulation materials used in building envelopes, by proposing a multi-functional and eNeRGy saving cementitious Foam (NRG-Foam). The heat-activated foam will be used for passive/active management of energy transfer and will be applied to new building envelopes and to retrofit existing ones. Graphene-based nano-additives will be doped in both cementitious foam matrix and bio-based PCM fraction for improving the thermal storage capacity, volume stability and mechanical properties of the resulting composite. Two active/passive systems will be prototyped and validated. First, an implicit heating system for thermal activation of the added nano-graphene will be installed representing a material-based approach, and, second, a multi-functional energy efficient façade system (MeeFS) will be installed, to diverse and direct the thermal absorption capacity and shadowing of the external building walls for optimizing the NRG-Foam’s.
NRG-Foam composites will be optimized to achieve the best compromise between thermal insulating properties (air bubbles) and heat storage capacity (bio-PCMs). A highly conductive cementitious paste will be designed and produced, targeting on an increase in thermal conductivity (once activated up to 10 times for bio-PCM, and 2 times for cement matrix), and an enhanced efficiency of bio-PCM heat storing performance (> 5 times). With this project, the partners will develop an innovative functional material that combines high insulation capabilities (more than 25% of classical layers) and high energy-storage capacity (more than 10% of improvement in active applications). Furthermore, the NRG-Foam layer will be characterized by a high water and air tightness (between 10% and 25% higher than existing solutions) and at least 15% lower costs than the actual solutions available in Europe for insulation purposes of non-residential buildings.
