Rehabilitation mortars for zero-impact buildings

Abstract

The selection of construction materials represents a Key step in any zero-impact building project. These materials account for several environmental impacts during their life cycle, and a significant part results from operational energy consumption. The need for new solutions which improve the environmental performance without compromising the buildings interior comfort, has emerged. In recent years, new materials with innovative features have been developed. The rehabilitation market is an emerging sector and it is necessary to develop new materials suitable for this specific application but with higher performance. The application of sustainability principles in buildings rehabilitation improves conventional buildings, reducing their environmental impact. In this work, a mortar with latent heat storage capacity and proper for buildings renovation has been developed. The latent heat is stored in the finishing mortars and released later, reducing the operation time of building heating or cooling systems and helping to achieve the zero impact goal.
