What are embodied impacts?

Embodied impacts are the impacts from the production of materials, their transportation to the construction site, and the construction process itself.

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 embodied environmental impact?

Embodied environmental impacts are defined as the environmental impact associated with the production building materials, accounting for both resource extraction, processing, and manufacturing, such as the highly efficient insulating materials and windows typically used in these buildings.

What is embodied carbon in construction?

Embodied carbon consists of all the GHG emissions associated with building construction, including those that arise from extracting, transporting, manufacturing, and installing building materials on site, as well as the operational and end-of-life emissions associated with those materials.

Why is embodied energy important?

Embodied energy is the total non-renewable energy that goes into the manufacture of a material and plays a large role in the choice of building materials. It is an important factor to consider when assessing the life cycle of a building and it relates directly to the sustainability of the built environment.

How do you reduce embodied energy?

10 steps to reducing embodied carbon

  1. Reuse buildings instead of constructing new ones.
  2. Specify low-carbon concrete mixes.
  3. Limit carbon-intensive materials.
  4. Choose lower carbon alternatives.
  5. Choose carbon sequestering materials.
  6. Reuse materials.
  7. Use high-recycled content materials.
  8. Maximize structural efficiency.

What is embodied energy of material?

Embodied energy is the energy associated with the manufacturing of a product or services. This includes energy used for extracting and processing of raw materials, manufacturing of construction materials, transportation and distribution, and assembly and construction.

What are the different types of embodied energy?

In buildings Examples of embodied energy include: the energy used to extract raw resources, process materials, assemble product components, transport between each step, construction, maintenance and repair, deconstruction and disposal.

What is the embodied energy of glass?

Embodied energy of common materials

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

What is the embodied energy of wood?

Embodied energy is the total amount of energy it takes to get materials to the job site. If we are talking about wood this includes the gas it takes to run the chainsaws, transportation to the mill/job site, and also the energy it takes to cut the timber and turn it into framing material.

How can we reduce embodied carbon in construction?

What is meant by embodied carbon?

Embodied carbon means all the CO2 emitted in producing materials. It’s estimated from the energy used to extract and transport raw materials as well as emissions from manufacturing processes. It can be used to design policies that reduce the CO2 emissions from the construction sector.

What is the embodied impact of construction materials?

The embodied impact of construction materials. The same research also calculated that, as a proportion of impacts from the built environment, materials are responsible for over 90% of elemental resource depletion, over 40% of POCP (summer smog) and ozone depletion, over 20% of water consumption, fossil fuel depletion and acidification,…

How is embodied energy being used in construction?

The world of embodied energy has moved on considerably since work started in the 1990s, and embodied carbon, Environmental Product Declaration (EPD) and Building Lifecycle Analysis (LCA) are now increasingly common in construction.

Which is an example of an embodied impact?

Their study considered the cradle-to-grave embodied impacts of an aluminum clad wood window and specifically studied argon, xenon, and krypton gases.

Is there embodied Impact Regulation in the UK?

Although embodied impact regulation still seems some way off in the UK, major developers here have recognised the significance of embodied carbon within their corporate activities, and sponsored the UK Green Building Council’s extremely popular Embodied Carbon Week early in 2014.
