Telescope Scope

This Circularity Passport Interiors aimed at highlighting the positive impact that reusing materials and products can have on the refurbishment of a working space. It was assessed to what extent products and materials used in a previous setting could be taken over and repurposed for a new space. This included determining how many products could be reused as-is (and how many needed some sort of prior treatment), if any material health issues could arise from reusing said products, and in what way the products could be further reutilized in future settings. In order to provide the most comprehensive analysis as possible, it was the objective to include as many products as possible.

Herb Material Sourcing

Background

In this category, the material origin of the selected materials or products is evaluated. The goal is for all materials to be either from renewable sources (i.e., renewable raw materials) or from secondary raw materials (i.e., recycled materials or the highest possible percentage thereof). To determine a summary indicator, the mass of all sustainably renewable materials and all recycled materials is added together and divided by the total mass of the building. This gives a result in (mass) percentages where one hundred percent is an ideal building and zero percent is the worst possible result.

Aggregation Method

Red Circle 5
0
Primary 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.

Footprints Carbon Footprint - Avoided CO2 Emissions

Background

The carbon footprint of a building (and any other product) is heavily dependant on the individual materials within said product. The potential environmental impact, presented as emitted CO2, can be calculated for each material as described below. Notably, a reliable assessment of material carbon footprints can highlight the importance of reusing products instead of producing new ones. By comparing the estimated carbon footprint that would occur if all products within a building were newly manufacured, with the estimated carbon footprint if only reused products were implemented, the avoided CO2 emissions can be easily visualized.

Aggregation Method

The formula to calculate the carbon footprint score on a 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:
CO2 = Carbon Footprint Score
i_mat = impact of the actual material
i_ref = impact of the reference material
a_mat = amount each distinct material

Information Material Level

The carbon footprint of the projects is calculated by summing the impact of each distinct material.
The footprint of each material is calculated by extracting potential impact information from suitable Environmental Product Declarations (EPDs), which are publicly available and meet the requirements of  DGNB New Buildings Version 2018 . The selection process of EPDs occurs according to the following method:  ⁠⁠Selection methodology for EPDs⁠ 
From those EPDs, the following life cycle modules according to DIN 15978 are then taken into account:

Impact of the actual material (i_mat)

  • For those materials that were newly manufactured, Modules A1-A3, (i.e. the raw material extraction, transport of these raw materials to the manufacturing site, and the actual manufacturing) are included.
  • For reused products, the impact can be considered to be 0, as the manufacturing occured in the past and therefore is not allocated to the assessed project.
  • For recycled Materials Modules A1-A3 and D (i.e. the net benefits and loads that occur due to the applied end-of-life treatment) are included.

Impact of the reference material (i_ref)

  • As the reference value has the same impact as a newly manufactured material, Modules A1-A3 are also included for the reference material.


Medical Symbol Material Health

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.
If there is publicly available information on the chemical contents of the used products, the rating is based on this information (mostly Safety Data Sheets and Ecolabels). EPEA Experts then assess whether these chemicals pose a risk or not.
In case the chemical contents of materials are unknown (for example, with reused materials), ratings are based on expert experience with similar materials. In this case, it can only be assessed whether risks can be expected.

Background During Use

The Material Health rating aims to promote the use of products that consist of completely defined chemicals that do not pose any risks. The values indicate to what extent the chemical contents of the materials used in this fitout are expected to be harmful to people and the environment during its use.

Background During Processing

The Material Health rating aims to promote the use of products that consist of completely defined chemicals that do not pose any risks. The values indicate to what extent the chemical contents of the materials used in this fitout are expected to be harmful to people and the environment after its use, i.e., during the processing of the product. Usually, the expected ways of exposure during processing are greater than those during use.

Aggregation Method

Nut and Bolt Material Reuse Potential

Background

Certain products can be re-used directly whilst others require processing such as a new impragnation or a coat of paint. The more products can be re-used directly, or with very little processing, the less energy and resources must be invested in manufacturing new products.
The Material Reuse Potential indicates the mass of materials that can be re-used in the future as-is, how much can be re-used in the future with processing, and how much cannot be re-used.

Aggregation Method

The formula to calculate the Material Reuse Potential on building level is the following:

Recycling Symbol Material Reutilization

Background

If they cannot directly be reused, 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
