Integrated porous cementitious Nanocomposites in non-Residential building envelopes for Green active/passive energy STORAGE

Start date: 01.04.2020

Duration: 48 months

Coordinator: Technische Universität Darmstadt

Budget: 6.85 M€


Thermal insulation materials are an integral part of building envelopes. They reduce heat transfer and optimise the inner thermal comfort. The EU-funded NRG-STORAGE project aims to launch a novel breakthrough insulation system that replaces available insulation materials with a multi-functional energy-storing and energy-saving cementitious foam (NRG-Foam). This ultra-high porous foam shows excellent insulation properties by embedding phase change and nanomaterials. What is more, the NRG-Foam layer will be characterised by increased water- and airtightness, will achieve at least 25 % improved insulation capacity. It will also be at least 15 % more economical than solutions currently available in Europe.

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.
