Concrete was the material of choice for much of the infrastructure built for the 2012 London Olympics. For example, for the Olympic Stadium Precast beams supporting the lower tiers were cast on the stadium site, there is 9,250 m3 of precast concrete within the stadium bowl. This 'on-site prefabrication' method produced some very high quality finishes. The Olympic Stadium used pre-cast elements and recycled aggregates as cement replacement to achieve a sustainable and robust home for the Olympic Games.
According to news outlet Euractiv, the European Commission plans to tackle healthier indoor environments as part of the energy performance of buildings legislation. Could this be a move towards taking a much broader approach to sustainable construction? I, for one, certainly hope so.

One of the challenges which we face today in terms of renewable energy is the mismatch between when this energy is generated and when it is needed. In order to make the most of the energy generated by renewables, such as wind and solar, flexibility is needed in the electricity grid. Heavyweight buildings can provide this flexibility by allowing for consumer energy demand to be shifted in time by using structural thermal energy storage.
Did you know that concrete can store energy and that, later on, this energy is then released? This effect, which is due to the high ‘thermal mass’ of concrete, makes buildings more energy efficient, lowers CO2 emissions, and improves wellbeing and comfort.
