Background
Construction is the single largest activity and industrial employer in Europe. In
addition, the greatest energy saving potential lies in buildings. However,
sustainability in the building sector must be assessed over the whole life cycle for
all building components and materials. Housing has been identified as one of the
three areas of consumption (together with food and drink, and private
transportation) that are responsible for 70-80% of the whole life-cycle impact of
products. In Mediterranean regions, the solar radiation in summer can cause overheating of
the building envelope (roof and walls) and the indoor environment, entailing the
need for air-conditioning. Passive systems to limit solar effect mainly consist of
ventilated facades and roofs as the element which is most exposed to solar
radiation. Vented roofs can greatly reduce heat due to solar radiation, but their
performance is highly dependent on roof exposure and, more importantly, their
perpendicular position to the wind. The benefit of so-called ‘above sheathing
ventilation’ (ASV) significantly decreases when the wind direction shifts from
perpendicular to parallel to the eaves line. ASV positively affects thermal
insulation thanks to convective heat transfer. Buoyancy-driven ventilation
becomes irrelevant even with a very weak wind, while the air permeability of tiles
determines an increase in performance. Thus, roof tile vents could be considered
the best solution for passive thermal insulation for buildings in hot and mild
climates. Objectives
The LIFE HEROTILE project aims to design and produce two types of roof tiles
(Marseille and Portuguese roof tiles, which cover more than 60% of pitched roofs
in Europe) with a shape characterised by higher air permeability through the
overlap of the tiles and improved energy performance through under-tile
ventilation. An air inlet will greatly increase the inflow of air and therefore the
heat disposal. In addition, the tile design will be independent of wind direction,
since the inlet and outlet channels will let the air flow horizontally as well as top
to bottom. The tiles will be tested on real-scale buildings with seven different roof types
and located in different Mediterranean regions. The project’s ultimate aim is to
demonstrate that the designed tiles can help save up to 50% of the energy for
cooling buildings. According to these estimates, the technology – if widely
adopted in the Mediterranean countries – could generate savings between 5 000
and 13 000 GWh of electricity per year, avoiding emissions of 1.5-3 million
equivalent tons of CO2.
Expected results: The project expects to achieve: A 50% reduction of energy consumption for cooling, equal to a value of 2.3
W/m3;
A 50% reduction of equivalent thermal transmittance of a vented roof
(equivalent U-value), equal to 0.25 W/(m2 K);
A 25% reduction of maximum under-tile air temperature;
A 30% increase under-tile yearly average air velocity;
A 50% reduction under-tile maximum radiation;
A 50% reduction of carbon footprint with regard to building cooling
applications in comparison with a standard pitched roof;
A five per cent reduction of electricity consumption for air conditioning in
urban areas, equal to 25 kW/ha;
A 10% reduction of greenhouse gas emissions (considering Mediterranean
EU countries cooling demand) up to 1.5 Mt CO2/year; and A five per cent reduction of air pollution (considering cooling demand
Mediterranean EU countries), up to 0.1 Mt PM2.5/year and of 1.0 Mt
NOx/year.
