Frequently Asked Questions

Which building material has the highest embodied energy?

As a result, the greatest amount of embodied energy in a building can be from either low embodied energy materials such as concrete or high embodied energy materials such as steel....Embodied energy of common materials.

MaterialPER embodied energy MJ/kg
Glass 12.7
Aluminium 170.0
Copper 100.0
Galvanised steel 38.0

What is embodied energy in construction?

Initial embodied energy: the energy required to initially produce the building. It includes the energy used for the abstraction, the processing and the manufacture of the materials of the building as well as their transportation and assembly on site.

What is the embodied energy in concrete?

The total energy intensity for concrete is calculated to be 11.01 MJ/€. Using the same assumptions as above this is converted to relevant units. The resultant total embodied energy, EE of concrete is calculated to be 0.298 MJ/kg. Consequently, the indirect EE of concrete is found to be 0.097 MJ/kg.

How do you calculate embodied energy of a building?

Embodied energy is measured as the quantity of non-renewable energy per unit of building material, component or system. It is expressed in megajoules (MJ) or gigajoules (GJ) per unit weight (kg or tonne) or area (m2) but the process of calculating embodied energy is complex and involves numerous sources of data.

Where does embodied energy come from in a building?

As a result, the greatest amount of embodied energy in a building can be from either low embodied energy materials such as concrete or high embodied energy materials such as steel. For most people it is more useful to think in terms of building components and assemblies rather than individual materials.

How are materials and construction methods affect embodied energy?

Choices of materials and construction methods can significantly change the amount of energy embodied in the structure of a building, as embodied energy content varies enormously between products and materials. Assessing the embodied energy of a material, component or whole building is often a complex task.

Which is lower in embodied energy steel or timber?

Lightweight building construction such as timber frame is usually lower in embodied energy than heavyweight construction. This is not necessarily the case if large amounts of light but high energy materials such as steel or aluminium are used.

How is embodied energy different from operational energy?

Embodied energy is not occupant dependent — the energy is built into the materials. Embodied energy content is incurred once (apart from maintenance and renovation) whereas operational energy accumulates over time and can be influenced throughout the life of the building.
