Abstract: In industrialized societies, buildings account for a large fraction of the overall energy use and a similar proportion of greenhouse gases emitted. Quantifying the embodied energy, that is the direct and indirect carbon emission in the production and utilization process, is an important component in the effort to reduce the carbon footprint. As well known, because of its many qualities, concrete is the most widespread building material, particularly concrete reinforced with conventional steel. Yet it has historically shown disadvantages in terms of durability and vulnerability to corrosion attack. Furthermore, these materials are energy abundant. Textile Reinforced Concrete (TRC), a combination of fine-grained concrete and textile fabrics, can offer a promising new alternative for its corrosion resistance and high performance properties, resulting lightweight and thinner structures, thus holds great potential in reducing the element embodied energy. This work studied the potential energy saving of concrete structural elements for massive building applications, by reinforcing them with layers of TRC, made of carbon instead of steel bars. Structural design calculations were performed to find the optimal structural configuration and validated with experimental data along with embedded energy calculation. The vast potential of reinforcing elements with epoxy impregnated carbon fabrics was clearly shown.
