Life Cycle Analysis

Comprehensive assessment of the impact of projects on the environment, its ecosystems and its resources

Today, the environmental quality of projects is assessed according to various criteria which include, for example, urban development, the landscape insertion of a building or users through the notions of comfort and even quality of life.

However, if we refocus on the environment in the sense that it represents our living environment in its natural state, we observe that it is made up of fauna, flora, water and many other resources that are impacted by human activity.

The principle of life cycle analysis (LCA) is to assess the impact of a project on natural environments by taking into account all the indicators that characterize it by encompassing all the procedures and processes that enabled the production and implementation of equipment and materials on site.

The various indicators we observe meet the following objectives:

Reduce waste :

  • waste produced (kg)
  • radioactive waste (dm³)

To preserve :

- the climate:

  • greenhouse effect (kg CO2 eq)

- health:

  • damage to health (DALY) which characterizes the impact in years of life lost

- the biodiversity:

  • damage to biodiversity (PDF/m².year) which characterizes the percentage of species diversity that disappears per m² and per year.

- the resources:

  • embodied energy (Joules) which represents all the energy spent from the extraction of raw materials to the implementation of a product
  • water used (m³)
  • depletion of abiotic resources (kg antimony eq) which characterizes the depletion of non-living resources naturally present in the environment

- forests:

  • soil acidification (kg SO2 eq)

- the rivers:

  • eutrophication (kg PO4 eq) which characterizes an excessive supply of nutrients in the water causing plant proliferation, oxygen depletion and an imbalance of the ecosystem

- air quality:

  • production of photochemical ozone (kg C2H4 eq) which characterizes the emissions likely to lead to the formation of ozone in the lower layers of the atmosphere by photochemical reaction (UV) and thus to a form of harmful pollution
  • odors (Mm³ air)

Synairgis offers you, through LCA and the evaluation of all these factors, to carry out comparative studies in order to optimize the impact of your project on the environment by reasoning over the entire chain. Manufacturing.

Beyond this exhaustive LCA, Synairgis also offers a carbon assessment of projects as part of the ongoing Energy-Carbon assessment and the new environmental regulations RE 2020.

- the climate:

  • greenhouse effect (kg CO2 eq)

- forests:

  • soil acidification (kg SO2 eq)

- health:

  • damage to health (DALY) which characterizes the impact in years of life lost


- the biodiversity:

  • damage to biodiversity (PDF/m².year) which characterizes the percentage of species diversity that disappears per m² and per year.

Our strengths:

  • extensive experience in the field with many feedbacks on construction systems and architectural choices
  • a carbon approach developed within Synairgis for all of its activities (particularly digital)
