According to the recent report by Edge Environment ‘Energy-efficient dwellings – Can embodied energy spoil the story?’ as buildings become more energy efficient, the energy it takes to make buildings becomes increasingly more important.
More attention should be paid to embodied emissions, as they are already significant and are becoming more so. Even so, embodied emissions cannot be ignored. While most lifecycle emissions are due to the building’s use, the building’s materials account for at least 10-20%. As the buildings become more energy-efficient, that proportion is rising and embodied energy is almost matching operational energy in the most efficient designs. Moreover, as designers can influence but not control occupant behaviour, their choice of building material may account for up to half of the lifecycle emissions that they can control.

Cape Brick, being the leader in environmentally friendly concrete masonry, is the supplier of choice when it comes to selecting masonry products with the lowest embodied energy.
An independent study by a leading University found that Cape Brick’s masonry units have the lowest embodied energy when compared to clay bricks, conventionally made concrete bricks and ash bricks.
