Energy Efficiency

Reducing the carbon dioxide emissions associated with the production of concrete and its constituent materials can be achieved by improving energy efficiency and reducing consumption. The indicator (kWh/tonne) also referred to as ‘energy intensity’ reports energy consumption during the manufacture of concrete products added to proportional contributions from each of the constituent materials. This is effectively a measure of the average embodied energy of all concrete produced (by the Forum members).

Performance indicator

Energy used in production as a proportion of production output (kWh/tonne)

 

energy used in production - rolling mix

 

In 2015, the energy intensity figure for the Rolling mix is 133.1 kWh/t. The figure for concrete and reinforcement is 156.0 kWh/t. The energy intensity figure for Standardised mix is 122.7 kWh/t. The figure for concrete and reinforcement is 146.5 kWh/t.

 

To provide an indicator that more accurately reflects the performance of the industry, energy intensity is now also shown as a baseline or standardised mix. This shows the energy intensity per year, based on the concrete mix of the 2008 baseline year.
