Building Life Cycle Assessment calculations require validated input
In previous Archicad versions, Building Material properties provided by Graphisoft as template content were outdated. Their source was not indicated so these values couldn’t be used for downstream building lifecycle calculations as validated input.
Updated Building Material property sets and values
Starting with version 26, Archicad provides up-to-date Building Material property sets and values for its out-of-the-box Building Materials, based on data published in the German ÖKOBAUDATdatabase. Use these validated properties to document embedded energy and CO2 footprint data for building life cycle analysis and sustainability reports.
The new Building Material properties are in the Environmental Property Group:

The last property in the group is the Data Source, which is a link that takes you to the page of the selected Building Material in the ÖKOBAUDAT database.
The table below contains the same descriptions of the properties:
Global Warming Potential (GWP)
Global Warming Potential: the insulating effect of greenhouse gases (GHG) - CO2 and methane - in the atmosphere preventing the earth losing heat gained from the sun. As global temperatures rise, it is expected to cause climatic disturbance, desertification, rising sea levels and the spread of disease.
Unit: kg CO2 eq.
Ozone Depletion Potential (ODP)
Ozone Depletion Potential: depletion of the ozone layer (O3) in the atmosphere caused by the emission of chemical foaming and cleaning agents allows the passage of greater levels of UV from the sun, causing skin cancer, damage to the immune system, and reduction in crop yields.
Unit: kg R11 eq.
Photochemical Ozone Creation Potential (POCP)
Photochemical Ozone Creation Potential: Creation of ozone in the presence of sunlight, nitrogen oxides, and volatile organic compounds. Ozone leads to chemical smog that affects human health, food crops, and the ecosystem in general. The effects vary according to geography and climate and are especially problematic in heavily urbanized areas with existing pollution.
Unit: kg Ethene eq.
Acidification Potential (AP)
Acidification Potential: emissions, such as Sulphur dioxide and nitrogen oxides from manufacturing processes, result in acid rain, which harms soil, water supplies, human and animal organisms, and the ecosystem.
Unit: kg SO2 eq.
Eutrophication Potential (EP)
Eutrophication Potential: increased concentrations of nitrates and phosphates can encourage excessive growth of algae and reduce oxygen levels. This increases mortality in aquatic fauna and flora, leads to loss of species dependent on low-nutrient environments, reduces biodiversity, and has knock-on effects on non-aquatic animals and humans.
These Building Material properties correspond with the EN 15804 sustainability standard, whose indicators are required in EPDs (Environmental Product Declarations) for construction products.
What are Environmental Product Declarations and Life Cycle Assessments?
Every product has its own life cycle. Careful assessment of the life cycle can tell you a lot about the product’s impact on the environment. The Life Cycle Assessment (LCA) looks at all stages of a product’s life: raw material extraction and processing, manufacturing, distribution, transportation, use, repair and maintenance, disposal, or recycling. EPDs are a form of life cycle assessment and are the standard way of quantifying the impact of a product or system on the environment.
Benefits of an Environmental Product Declaration
Clients, developers, and designers use EPDs and LCAs to select products that have the lowest impact on the environment. An architect who understands the entire life cycle of building materials can help create a more sustainable building industry.
Relying on the environmental Building Material properties helps architects select materials for their projects that have a lower impact on the environment.
Reliable embedded energy and CO2 footprint data
Archicad users receive validated and reliable embedded energy and CO2 footprint data for Building Materials and can use it confidently for building life cycle analysis and sustainability reports.
