Expected Results:

• The industrial design of n.2 tile shapes for Marseillaise and Portuguese
• A pilot industrial line production (with an hourly production of 5.000 pcs) of 20.000 tiles equivalent to 1500 m² of the previous tiles for covering the roofs of two sample buildings (mock-up, 150 m² each one) and two demonstration buildings (social houses, 300 m² each)
• The results of the experimental checks at real scale of the energy performance in comparison with traditional solutions, by means of two sample buildings located in two different sites and equipped with double monitoring system for collecting data in real time. The better performance should reduce up to 2-4°C the temperature the under roof building volume in comparison with the same in a flat roof.
• The results of two demonstrator buildings, both equipped for collecting energy data for space heating and cooling. The expected results should achieve an energy savings in cooling mode up to 30- 50% in the under roof building volume, avoiding higher energy consumption in heating.
• N°1 freeware software for supporting technicians and stakeholders in designing and planning similar applications with regards of their energy behavior according location, climate, building topology and use.
• Estimated benefit up to 30-50% of energy requirement during summer, compared to a similar roof without ventilation.
• The increase of energy consumption in heating mode in wintertime is equal to 0. In winter time the novel roof tiles allow a better control of the moisture by ventilation producing indirect benefits due to the increased dryness of the insulation layers.

Environmental Benefits:

Considering that the tiles types to be re-designed and produced during the project cover more than 60% of European roofs and that the industrial partners involved in LIFE HEROTILE work at European level, it could be expected to cover a good market share, above all in the Mediterranean basin Countries, and to reach the following targets:

• 10% Reduction in greenhouse gas emissions, (South Europe), equal to an absolute (Yearly) value of 1.5 Mt_CO2/year
• 50% Carbon footprint of building space cooling in comparison with standard pitched roof, equal to an absolute (Yearly) value of 150 g_CO2/kWhe
• 5% Reduction of air pollution, (South Europe), equal to an absolute (Yearly) value of 0.1 Mt_Pm².5/year and of 1.0 Mt_NOx/year
• 5% Reduction of electrical power for air conditioning in urban area, equal to an absolute (Yearly) value of 25 kW/ha
• 25% Reduction of maximum under-tile air temperature
• 30% Increase under-tile yearly average air velocity
• 50% Reduction under-tile maximum radiation
• 50% Reduction of specific cooling power of novel solution, equal to an absolute (Yearly) value of 2.3 W/m3
• 50% Reduction of equivalent heat transmittance of a vented roof (equivalent U-value), equal to an absolute (Yearly) value of 0.25W/(m²K).
