Medical Symbol Material Health

Background

Problematic ingredients in products can not only pollute the environment, but are also regularly found in the human body. That's why we strive not only for compliance with legal limits and "less bad" chemistry, but also for ingredients that are positively defined from the outset. Only in this way can we create products and buildings that are beneficial to people and the environment.
This is the only category that is aggregated by piece of distinct material instead of mass. This was decided because the auxiliary materials with low total masses are usually the ones that cause the most health issues. Therefore a mass weighting would not properly represent those materials.
The Material Health rating aims to promote the use of products that consist of completely defined chemicals that do not pose any risks.

Aggregation Method

The Formula to calculate the Material Health score on building level is the following:

Whereas:
HEA = Material Health Score
q_mat. = weighting of each distinct material

Herb Material Sourcing

Background

The aim is for all materials to be made from either "renewable sources" i.e. renewable raw materials or secondary raw materials i.e. recycled materials, or to have the highest possible proportion of these.

Aggregation Method

The Formula to calculate the Material Sourcing score on building level is the following:
This element (formula) isn't supported, or may require an update to be displayed. You can try to refresh the app.
Whereas:
SRC = Material Sourcing Score
q_SRC, mat. = quality factor of each distinct material
m_mat. = mass of each distinct material
m_bui. = total mass of the building

Secondary material
Products made from secondary material. This includes all maintained, reused, refurbished or post-consumer recycled materials.
Green Circle 2
1,0
Sustainably renewable material
Products made from renewable material from certified sustainable cultivation. The criteria to classify a product as "sustainably sourced" is taken from the EU-Taxonomy definition.
Black Circle 3
0
Primary, non-renewable material
New raw material that has never undergone any processing other than manufacturing. This also includes pre-consumer recycled materials. In case the source of the materials is unknown it is assumed to be primary material.

Recycling Symbol Material Reutilization

Background

Resources should be able to serve as raw materials for new, pollutant-free products after their use. In this way, they can continuously circulate in product cycles - instead of "downcycling", the "re- and upcycling" of products should be made possible.

Aggregation Method

The Formula to calculate the Material Reutilization score on building level is the following:

Screwdriver Separability

Background

The aim is that all constructions can be disassembled into their component parts or recycling units. Detachable joining techniques should be used for this purpose. Composite construction materials should be avoided wherever possible in favor of separable assemblies.

Hammer and Wrench Dismountability

Background

Non-destructive deconstruction should be aimed for at the component level (functional units). The aim is to increase the flexibility of the building through the easy interchangeability and adaptability of individual functional units planned in advance. The added value is higher third-party usability, easier reconstruction and thus a longer overall service life.

Footprints Carbon Footprint

Background

A reliable climate protection strategy for a building can reduce future risks and thus increase property values. Shown is the carbon footprint of the construction compared to a standard building. This category evaluates the CO2 emissions associated with the building through construction and operation. The goal is a climate-positive building, in which CO2 is bound and stored as well as the consumption of 100% renewable energy, which is optimally self-produced. The carbon footprint is documented by cost group in the Circularity Passport Buildings.

Aggregation Method

The Formula to calculate the carbon footprint score on building level is based on the DGNB-methodology for lifecycle assessments:  DGNB New Buildings Version 2018 . The result of the LCA is set in comparison to the reference value of 9,4kgCO2/m²a which is also provided by the DGNB. A value 9,4 represents a usual building and therefore is set to receive a score of 0% whereas an ideal building would cause no carbon emissions at all (0kg/m²a) and receive a score of 100%. The Carbon Footprint Score is thus calculated as following:
