Descripción del proyecto
Aislamiento para el almacenamiento ecológico de energía
Los materiales de aislamiento térmico forman parte de las envolventes de los edificios, donde reducen la transferencia del calor y optimizan el confort térmico en el interior. El proyecto NRG-STORAGE pretende lanzar un nuevo sistema de aislamiento rupturista que sustituye los materiales de aislamiento disponibles por una espuma cementosa multifuncional que almacena y ahorra energía (NRG-Foam). Esta espuma con porosidad ultraelevada presenta excelentes propiedades aislantes gracias a su contenido de materiales de cambio de fase y nanomateriales. Además, la capa de NRG-Foam se caracterizará por una mayor estanqueidad frente al agua y el aire y ofrecerá una capacidad de aislamiento como mínimo un 25 % mayor. Además, será al menos un 15 % más económica que las soluciones disponibles actualmente en Europa.
Objetivo
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.
