Embodied energy in construction

Embodied Energy (also known as embodied carbon) is the summation of the energy required to produce a product. The concept behind this is the energy is 'embodied' within the actual product. The concept is relatively new and has yet to impact [[Sustainability%20legislation|Sustainability_legislation]]. 

It was first considered after the industry began to assess the operational energy of buildings. This is looks at the life-cycle operation energy in detail, it was assumed that the service and maintenance operations during a buildings life-cycle were considerably more than the processes used to construct the building (The Living Rainforest, 2013) . After careful assessment this found not to be true, with some analysed building's embodied energy amounting several years of maintenance. 

The process involves measuring or estimating the total energy. The estimation process may include measuring gas usage, electricity, oil, or workmanship. Anything of value. It often includes features that cannot be easily be assumed as commodities such as water, ecological factors and plants. 

The main components of embodied energy are activities of extraction, manufacturing and transportation are the main sources of this energy. These processes are largely the most energy consuming. 

Embodied energy is a subsection of [[Sustainability|Sustainability.]]Derived from the requirement for sustainable building design processes, embodied energy is an emerging topic at construction exhibitions like [[Ecobuild|Ecobuild]]. 

= Embodied Energy or Embodied Carbon =

Embodied carbon is often perceived as being synonymous with the preceding. They are not the same. Embodied carbon is the associated carbon emissions of constructed building materials or products. It is the carbon emit of sourcing and processing raw materials. It is more concerned with mechanical and chemical operations and the by-products these create. Embodied carbon measures the carbon dioxide of processing materials. 

The two can often produce very different figures. For example cement has an embodied energy of 4.5 MJ/kg but has an embodied carbon value of 0.73 kg CO2/kg (Source: The University of Bath ICE, 2013). 

= How embodied energy is measured. =

At present there is no legislative requirement to measure the energy that produces construction materials of buildings. The measurement process involves identifying the relevant production means. This may include but is not always limited to: 
*Extraction 
*Manufacturing 
*Transportation 
*Construction 

Using this method forms a detailed map of the energy processes throughout the various stages of a products life (Source: The Institute of Structural Engineers, 2013). 

The industry has developed a system of incorporating the various stages. These are referred to as 'cradle to gate', 'cradle to site' and 'cradle to grave'. Together they form the system boundaries of the assessment of embodied energy. Most products are measured by the 'cradle to the gate' method which includes all the stages from extraction to completed product. 

The units for embodied energy are MJ/kg, represented as megajoule / kilogram. This is the energy density of a material.
