About the project Hringvangur—the first (and only so far) Icelandic network for circular construction—was opened as a public-private project as part of the Nordic Networks for Circular Construction (NNCC) project, realised in Iceland by Húsnæðis- og mannvirkjastofnun (HMS) and Grænni byggð . In 2024, Hringvangur was launched and hosted by Grænni byggð with support from HMS and Verkis. Now, operations must be sustained in the following year and built on the existing solid foundation. Overview The project's primary goal is to continue Hringvangur's statutory activities, which are, among others:  managing the platform to promote circular projects and solutions in Iceland; managing the website as a database of existing knowledge on various aspects of circular construction; updating stakeholders with the state-of-the-art; acting as a contract platform to facilitate cooperation between stakeholders. Hringvangur website The project received a grant from Askur - mannvirkjarannsóknasjóður which is funded by Húsnæðis- og mannvirkjastofnun (Icelandic Housing and Construction Authority), Ministry of Social Affairs and Housing and the Ministry of Culture, Innovation and Higher Education.

Some information about EPDs,PCR and some EPDs for Icelandic products. Environmental product declarations (EPDs) An environmental product declaration (EPD) is a document providing confirmed information about the environmental impact of the product's life cycle based on the results of performed life cycle assessment (LCA). The EPD also contain the information required by the specific Product Category Rules (PCR) and General Programme Instructions . Eventually, EDP is verified by a third party who evaluates the analysis independently. As the methodology of its preparation is regulated, EPD help build transparency and increase confidence that environmental claims made by manufacturers are accurate. In many ways, such a statement is similar to the ingredient descriptions of food products, but instead of information on nutritional value, there is information on the product's environmental impact. The first Icelandic EPD was published for Steinull , based on the analysis done by EFLA , confirmed by SINTEF building research in Oslo and published by EPD-Norge . More information on EPDs can be found on the International EPD System website or in the presented video. An open EPD database can be found on the InData network website . Product Category Rules (PCR) A Product Category Rule provides specific instructions for how life cycle assessment (LCA) should be performed for a particular product category. More precisely, it includes, among others, the so-called system boundaries (which processes and product's life cycle stages should be considered) and declared or functional units, which should be used for specific products. More information on PCR can be found on the International EPD System website , and the PCR library can be found here .
