Standards and recommendations

We and/or our members create new standards and concepts for sustainability

Rexs – Requirements Exchange Standard

The amount of sustainability requirements and other requirements is large and increasing in all industries. Requirements are managed manually, defined in different document formats, and sent between parties via email, leading to inefficiencies and risks. This is addressed by Rexs enabling digitization of the requirements management process by describing how requirements can be structured for digital handling. This means that requirements can be stored and exchanged digitally between systems and organizations for better management. The 100 Group has contributed to the development of Rexs and is now responsible for maintenance and communication of the standard.

PTI - Product Templates for Inventory

In the circular economy, inventory is used as a tool for mapping reusable building components. In the inventory process, each type of building component is assigned a name and properties, such as a certain type of door with a certain fire rating. The names and properties are saved in databases to help interested parties find reusable components. But reuse actors have their own names and property definitions, making it difficult for interested parties to find parts and understand the definitions. Therefore, our members within reuse of building components have taken initiative to further develop, spread and start using a product template from the member Kompanjonengruppen. The template defines a large amount of building components and their relevant properties with standardized values. The definitions are made available digitally by the 100 Group for easier use in inventory and to facilitate database information exchange and search.

Recommendations for sustainable interior design

Climate change sets new demands on all actors in the design and building industry. In the transition from a linear to circular economy, interior designer’s role will change towards having higher responsibility and importance in all project stages. Although the industry today is working more and more with reuse, with new circular business models being developed on a daily basis, it still lacks clear recommendations that cover all sustainability perspectives.

Therefore, several architectural offices that are members of the 100 Group are working on developing recommendations and guidance for working with sustainability in interior design assignments. The recommendations will cover all sustainability perspectives – environmental, social and economic. They will be evidence-based and contain design principles, goals, and reference values where these exist, as well as a process description that ensures that sustainability aspects are integrated and handled during all project stages, as well as maintained throughout a project’s lifecycle.

If you want to know more, please contact Ivana Kildsgaard.

To facilitate the development and uptake of digital standards and methods widely in the industry we organize 2-3 dedicated member meetings per year on this topic.  


Let’s build a circular and sustainable interior industry together before 2030.
