Circular economy 1) Eliminate waste and pollution Waste is the result of decisions made at the design stage. Therefore, it is essential to change our mindset when it comes to design and consider waste generation a design flaw. The construction sector plays a crucial role in implementing a circular economy as it is responsible for considerable resource use and waste generation. To prevent our planet's resources from running dry, we need to change our consumption habits and production methods radically. The circular economy can be explained using three main principles from the Ellen MacArthur Foundation :  2) Circulate products and materials (at their highest value) It is important that the products and materials we produce remain within our economy. Therefore, ways of their reuse, repair, or recycle must be widely available. 3) Regenerate nature The circular economy plays in favour of nature in multiple ways by moving from extraction to regeneration, for instance, by reducing the amount of raw materials needed to be mined, thereby returning more land to nature. Currently, a few of the most significant barriers to implementing circular economy principles in the construction sector are: - lack of legal frameworks regulating the reusing of materials, - lack of data on material flows and the quality of materials, - lack of knowledge of circular design. There are several initiatives to solve the above issues. The first example is the criteria for circular buildings created by FutureBuild , stating that a circular building must consist of at least 50% of reused and reusable components. The criteria also cover other aspects, like, for example, design-for-adaptability. More information can be found here (FutureBuilt kriterier for sirkulære bygg ; in Norwegian ). The second example is the EU's set of guidelines for legal and technical stakeholders and policy-makers in the construction sector on how to implement circular economy principles, which can be found here . Hringvangur A network for circular construction in Icelandic building industry was created at the end of 2023. The network is called Hringvangur and Green Building Council Iceland is the host for now. The website is www.hringvangur.is Additional information Does it cost more to renovate than to build new? Answers to this and other questions can be found in GBC Norway's publications Tenk deg om før du river (Think before tearing down; in Norwegian ). Guidelines and business tools for companies in the construction sector on how to implement circular solutions in their activities can be found in Nordic Circular Economy Playbook 2.0 .

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 .

Certifications There are many different types of environmental certificates for buildings, but in general, it can be said that the goals of using them are to: - Increase the quality of buildings. - Reduce negative environmental impact. - Build healthy and safe buildings. - Reduce operating costs. In Iceland, two certification systems have been extensively used to certify buildings and areas: BREEAM and the Nordic Swan. BREEAM BREEAM is one of the most well-known environmental certification systems for buildings today, which encourages sustainable building design and ecological management during construction and operation. The BREEAM certification system uses a recognized requirements framework to assess the performance of a building's design, construction time and operating time, taking into account numerous factors, from ecology to energy consumption. These factors are included in the form of nine environmental sections having varying degrees of weight, as can be seen below: More about the BREEAM certification can be found here . BREEAM-certified buildings and construction in Iceland can be found here . The annexe for the BREEAM certification of Sundhöll Reykjavíkur (swimming pool in Reykjavik) in Icelandic can be found here . THE NORDIC SWAN ECOLABEL The Nordic Swan is a co-Nordic certification system that can be seen widely on products of various kinds. The Swan's certification system is rapidly growing buildings in the Nordic countries and elsewhere. In Iceland, the Environmental Agency is the coordinator of the Swan, and its staff is responsible for assisting companies through the certification process and granting permission to use the logo. More information on the Swan certification and the list of Swan-certified buildings can be found here . Other certification types LEED Leadership in Energy and Environmental Design (LEED) is a green building rating system commonly used in the U.S. and Canada. It was created in the early 90s by the United States Green Building Council. More information on LEED can be found here . Level(s) Level(s) is a framework developed by the European Commission to assess and report on the sustainability performance of buildings. More information on Level(s) can be found here or in the video below.

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.

Information on LCA and LCC. Life cycle assessment (LCA) Life cycle assessment (LCA) is used to evaluate a product or service's local and global environmental impact over its lifetime or "from cradle to grave". More precisely, the overall environmental impact is analysed, so the one occurring at all stages of the ecosystem or across the entire value chain, i.e. due to the acquisition of raw materials, production, use and disposal. The framework and methodology of performing LCA for buildings are presented in the EN 15978 standard (Sustainability of construction works - Assessment of environmental performance of buildings - Calculation method). According to the standard, the LCA results are presented for five main phases, and each phase is identified with a letter and serial number: The following software can, for example, be used to create an LCA for buildings: One Click LCA - Simple LCA calculations in the design phase of buildings Danish LCAbyg - From Denmark: Statens Byggeforskningsinstitut, Aalborg Universitet Copenhagen Green Delta’s OpenLCA – From GreenDelta in Berlin, Germany Life cycle costing (LCC) Often, Life-cycle costing (LCC) is performed together with LCA. LCC is used to analyseall the costs incurred during the asset's lifetime (e.g., product, service, building). The considered costs are, among others, purchase costs and costs associated with that (e.g., delivery or installation costs), operation costs (e.g., energy or fuel costs, maintenance costs), and end-of-life costs (e.g., disposal or recycling costs). LCC can also include the asset's residual value, so potential revenue from its reuse or sale.
