Leiðbeiningar um endurnýtingu byggingarefna og ábyrgt niðurrif (BGF 4.9 , 4.10 ) About the project Grænni byggð worked within two actions in Vegvísir að vistvænni mannvirkjagerð 2030: 4.9. Gefa út leiðbeiningar um úrgangsforvarnir, undirbúning fyrir endurnotkun, endurvinnslu og aðra endurnýtingu byggingarefna við hönnun nýrra mannvirkja og á endurbótum . 4.10. Gefa út leiðbeiningar um ábyrgt niðurrif . To address the objectives of these two actions, the concise yet informative materials were published on the Hringvangur website . The two actions were tackled collectively as they are interwoven (i.e., reuse and recycling of materials is a significant part of selective demolition). The materials contain information on, among others: Circularity potential of most commonly used materials and products (e.g., concrete, steel, wood, glass, sanitary equipment, fire equipment, indoor products – windows, door, ventilation ducts); Environmental motivation standing behind circular practices and selective demolition with examples of real-life circular solutions and projects; New roles and responsibilities of chosen main stakeholders in circular projects.

About our partners in the CIRCON project. Project partners Our project partners have long-standing experience in both practical and research aspects of circular economy implementation in the construction sector. Polish Green Building Council (PLGBC) Polish Green Building Council (PLGBC) has realised the mission of making sustainable construction the norm in Poland since 2008. To do so, they cooperate with a broad range of experts, ranging from architects through local governments, scientists, other NGOs, enterprises to media companies. The key areas of their activities are buildings decarbonisation and adaptation to climate change, circular economy in the construction sector, biodiversity increase, and improvement of society's quality of life. Home Silesian University of Technology (SUT) The Silesian University of Technology (SUT) is one of the leading Polish universities in technology and innovation. The team appointed to the project has over 30-year experience in waste management and circular economy principles, gained while working with national and international research, governmental, and industrial partners.

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 .

Information on circular economy principles in construction. Construction boards The handbook was created as an early-stage guide for those considering reuse. The guide focuses primarily on reuse potential, with practical tips and the legal and hazard-related barriers associated with it. Additionally, it covers recyclability and potential carbon emission savings. Below is a list of materials, along with their reuse potential and associated hazards; the full handbook is available here.

About Nordic Green Building Councils Network. Nordic Green Building Councils Network To strengthen the transition of Nordic countries to more sustainable, together with Green Building Council (GBC) Denmark , GBC Finland , GBC Norway , and GBC Sweden , we established the Nordic Green Building Councils Network (Nordic GBC Network). We realise our goals by, among others: - organising Nordic Green Building Council Conferences in 2011, 2013, and 2015; - realising the Nordic Urban Development project (2014-2015) aiming at creating the framework for sustainable urban development; - realising the Nordic Guide to Sustainable Materials project (2014-2015) aiming at creating guidelines on sustainable, functional criteria for building materials , which included specificity of the Nordic construction market (e.g., materials, production methods, practices used, legislation, and market drivers). - organising educational and professional webinars: > Nordic GBC Webinar #6: Nordic Sustainable Infrastructure Webinar (13/09/2023); > Nordic GBC Webinar #5: Circular Economy in the Real Estate and Construction Sector (03/10/2022); > Nordic GBC Webinar #4 : Resilience and Climate Adaptation (19/01/2022); > Nordic GBC Webinar #3 : Renovation of buildings and the Circular Economy (30/09/2021); > Nordic GBC Webinar #2 : How can we half emissions from construction in two?
