LIFE HEROTILE aims to improve the energy behavior of the buildings through the development of innovative types of roof tiles able to increase their underlay ventilation.
Thanks to technologies and systems suitable for being replicated, transferred or mainstreamed, the project will contribute therefore to the development and implementation of energy savings approaches, mainly at Mediterranean Region, and to climate change mitigation.
Two pilot plants
to produce two new types of roof tiles with a shape characterized by a higher air permeability through the overlap of the tiles, and then a better energy performances by passive disposal of the solar radiation through under-tile ventilation
Two real scale test buildings
with seven different roofs each, will be made to test new tile performances in two different location (one outside EU) and two demonstrator buildings located in Mediterranean regions have been chosen to test and quantify benefits of new tiles
A practical and simplified software
for architects and technicians, able to predict the energy performance of different roof configurations. The software will be free-license.
