Objective of the project
Energy demand for heating and cooling represents a large part of non-residential buildings' energy consumption around the world. To attenuate and optimise this energy consumption, thermal insulation of construction and building elements, like walls, roof and floors, is particularly important and worth of development for energy conservation. Building envelope (either in residential or non-residential applications) is actually one of the most important building objects that could take effective energy designs and innovations. Storing solar and/or environmental heat/cooling energy in building components of non-residential constructions is a way to level-out daily temperature differences and to significantly cut back energy demands.
A way to achieve this goal is to develop novel, yet feasible for the civil engineering sector, Phase Change Materials (PCMs) – based cementitious products, characterised by a specific/responsive porous microstructure that accommodates the PCMs and has the potential to store/release energy due to a reversible and repeatable change from a solid to a liquid phase and vice-versa.
Based on this goal, the project will address the main objective:
The main objective of the project is to develop and demonstrate a novel ultra-light cementitious and non-flammable insulation material that includes Phase Change Materials for both active/passive energy storage in non-residential buildings. The NRG-STORAGE project will ultimately contribute to the vast growing market of building envelopes, for both retrofitting and newly built objects, by implementing the TRL levels 5 to 7 of a next generation of prefabricated insulation material, called NRG-Foam. The proposed product will have more than 25% improved insulation capacity, more than 10% higher energy-storage capacity, at least 10% higher water and air tightness, and less than 15% cost increase than the actual solutions based on synthetic materials, glass fibres or stone wools.
