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 The programme Nordic Sustainable Construction is part of Nordic Vision 2030 initiated by the Nordic Ministers for Construction and Housing. The Ministry of Infrastructure of Iceland is responsible for the fourth work package, Emission-free construction sites . Green Building Council Iceland and the Housing- and Construction Authority of Iceland support the Ministry in solving the assignment. The program is financed by Nordic Innovation, an organization under the Nordic Council of Ministers . Overview The Nordic countries are among the first in the world pursuing to set normative limits for the emission footprints of buildings. With the work package on Emission-Free Construction Sites, we are going into depth with one of the modules in a building's life cycle, the construction phase. Until now, the main focus has been on greenhouse gas emissions from the production of building materials and the operational phase of buildings. This is changing as recent studies show that construction phase emissions are a substantial part of the whole life cycle emissions. In buildings where emissions from the operational phase have been minimised, construction process emissions may be up to 15% of the entire life cycle emissions. The main contributors to emissions are transportation, construction machinery, and energy use for heating and drying. Waste and lost material also contribute to increased greenhouse gas emissions and must be considered in the construction process. Construction machinery, heating, and transportation rely largely on the combustion of fossil fuels. This has a negative effect on both global climate and local air quality, especially in urban areas. Combustion of fuels produces nitrous oxides, particulate matter, and other airborne substances that negatively affect public health. The intent of the work package is to diminish carbon and other direct emissions at construction sites, e.g., by supporting the transition towards emission-free construction sites. Including the use of emission-free power sources and planning the seasonal use of heat and light at construction sites, but also through the development of logistical solutions to conserve transportation and handling resources in a way that diminishes emissions and resource usage. Currently, none of the Nordic countries has set normative criteria for emission-free construction sites, and the Nordics thus have a unique opportunity to harmonise regulations and guidelines. To create support, visibility, and a solid foundation for an increased focus on low-carbon construction, including emission-free construction sites, a common Nordic declaration will be formulated. Steps will be taken to ensure its endorsement and acceptance by the Nordic construction industry. Progress Report - published 16th of March 2023 Throughout the first phase of this work package, the focus has been on gathering Nordic and European input to publish a report that analyses and determines the general definitions, boundaries, and terminology of the emission-free construction site area. This describes the status of the field today and is a good preparation for the next steps in the area. A standard definition of construction site boundaries and what emissions are included is a foundation for cooperative Nordic development in this field. Read the report: https://www.norden.org/da/node/79878 Network of stakeholders The work package has also established a network for cooperation which gathers the industry's stakeholders to share and gather information on innovations, gains, and prospects. There is a great interest in emission reduction in the construction process among actors in the value chain. Housing authorities and large public procurers are the main driving actors, but industry associations, building contractors, and equipment manufacturers have already started the journey. The network will facilitate brokering events on construction issues. Sign up for the network: http://eepurl.com/imRdFM Excursion to construction sites Last February, we visited the ambitious construction site in Aarhus, Denmark, The Green Construction Site of the Future. A sensory net around the site measures emissions. Biodiesel machinery is mainly used, but a 23-ton electric Volvo excavator has been tested together with a fast charger from DTI (Danish Technological Institute). The visit aimed to show real working solutions. Here you can find an interview where Lars Overgaard, the Senior project manager at DTI, talks about the project: https://youtu.be/GqktRe3k7KA The way towards emission-free construction sites - Online event An online event was held to promote the publication of the report. There, we also introduced the Nordic network of cooperation and displayed the video from the site visit to the Green Construction Site of the Future. The event's moderator was Hólmfríður Bjarnadóttir, and specialists from Volvo CE and SiteHub talked about their way towards emission-free construction sites. Recording of the event: https://www.youtube.com/watch?v=PNRE0HAhaSw Next up During the project's next phase, the work package will focus on future research needs, collect information about Nordic funding organisations and encourage more emphasis on this topic. A report on future research needs for emission-free construction sites will be published. Emphasis will be placed on strengthening the cooperation network and encouraging debate on important topics regarding incentives, funding, barriers, and more. Upcoming activities → Nordic Declaration on emission-free construction site endorsed by the Nordic Ministers of housing and construction and by the Nordic actors in the construction industry. → Encourage and facilitate Nordic research and innovation to support emission-free construction sites. → Encourage and facilitate the development of guidelines for procurers and construction companies on emission-free construction sites and produce an online guide.

Newsletter 16.06.2023 Helsinki Central Library Oodi The CIRCON compendium includes over 25 case descriptions representing circular construction aspects in practice. One is the Helsinki Central Library Oodi, an example of the design-for-adaptability principle combined with high sharing potential. The building’s structure has a form of an asymmetrical bridge consisting of steel trusses and beams supported by two massive steel arches. This solution resulted in a column-free interior space with high spatial flexibility and adaptability. As a result, the space has a unique, inclusive vibe attracting hundreds of visitors every day. Currently, it is used as, among others, a library, a conference and exhibition venue, a co-working space, a photo and recording studio, an office space, or a café and restaurant. More information about the building can be found here . The CIRCON project benefits from a € 361,422 grant from Iceland, Liechtenstein and Norway through the EEA Grants and co-funding by the national funding of Poland. Co-funding from the Polish state amounts to € 54,213. 23.05.2023 Lecture on the circular economy in the construction sector We had the pleasure of giving a lecture to the students from Aalto University in Finland on circular construction. Besides discussing the general overview of the aspects of circular economy in the construction sector (e.g., design-for-adaptability or design-for-disassembly), we also tried to debunk some myths about circular construction – is it always more expensive than conventional construction or are all aspects of the circular economy always related to lower carbon footprint? We’ll discuss these issues further also in our meetings organised in the future.

Co-funding from the Polish state amounts to € 54,213. 10-11.05.2023 Partners' meeting in Poland Last year, in August, our Polish partners in the CIRCON project visited us in Iceland. Now it was our turn, and we went to Poland for our partners’ meeting last week. As we’re in the second part of the project already, we not only discussed our further steps but also celebrated our progress so far. We also had an opportunity to take a closer look at many old industrial buildings preserved as a part of the cultural heritage of the Silesian region in Poland. In the photo, you have an example of a multi-family house initially designed for industrial workers, typical for the end of the 19th century and the beginning of the 20th century in the industrial towns of Silesia.

Co-funding from the Polish state amounts to € 54,213. 28.04.2023 Second work package is completed By the end of April, the second work package in the CIRCON project will be completed. Recently, we had two working group meetings at which we predominantly discussed barriers (with their possible solutions) in implementing circular construction in Iceland. The outcome of these discussions will be published in the upcoming months. But maybe you have some ideas on how to facilitate circular construction and want to share them?

Co-funding from the Polish state amounts to € 54,213. 27.04.2023 Green Leap in Iceland’s construction sector Around 300 people took part in the Grænt stökk í mannvirkjagerð (Green Leap in Iceland’s construction sector) event discussing the transition to more sustainable and circular construction. The main message that can be taken from all of the speeches is: we can do it, but we have to work together to make the transition happen . The key lecture was given by Anders Lendager, the CEO at Lendager , who proved that circular construction is possible and dispelled the myth that circular building is always much more expensive than conventional one. His partner in Iceland, Arnhildur Palmadottir , showed her projects proving that circular construction is possible also in Iceland by playing with locally available materials. In the same subject, we presented a brief overview of new challenges and changes in the roles of stakeholders when switching to more circular construction, one of the outcomes of the CIRCON project. We also discussed other ongoing and recently completed projects, with an emphasis on those related to the Byggjum grænni framtíð - Roadmap towards sustainable construction . The recording of the meeting can be found here . The event was organised by Húsnæðis- og mannvirkjastofnun with Samtök iðnaðarins and Green Building Council Iceland.

Co-funding from the Polish state amounts to € 54,213. 01.12.2022 Nordic Circular Summit Despite the break in our meetings in the CIRCON project, we are not sleeping. Last week we participated in #NordicCircularSummit – the biggest conference on circular economy in the Nordics organised in beautiful Stockholm. There were so many insightful presentations regarding circular construction that it is hard to mention them here. For those who could not attend, keep an eye on the event’s website – presentations should be uploaded in the nearest weeks. But two blunt end messages need to stay with us: 👉🏻As Kari Herlevi from Sitra said: “It is not just about maximising value; it is about reducing the negative impacts and then moving on to being nature positive ”, and, following Nancy Bocken from Maastricht University: “There is no business to be done on a dead planet, so focus on regeneration! ”.👈🏻 Last but not least, the next #NordicCircularSummit 2023 will be in Reykjavik!

Co-funding from the Polish state amounts to € 54,213. 31.10.2022 First work package is completed With the end of October, the first work package in the CIRCON project is completed. As the last part of the first work package, we had two working group meetings at which we discussed the created circularity indicators, which will be a part of the primary project outcome - guidelines on the circular design. The proposed circular indicators 🏠 take into account the following: - the amount of secondary materials used in the construction or renovation process; - the amount of waste reduced during the demolition or renovation process; - building's adaptability and disassembly potential; - the potential for sharing space; - building's energy efficiency. The guidelines with the circularity indicators should be published at the latest in summer 2023.

Co-funding from the Polish state amounts to € 54,213. 05.08.2022 Our visit in Drangar As a part of our partners' meeting in Iceland, we visited one of the rare European examples of rural buildings redefined and reconstructed in the spirit of the circular economy - Drangar. Drangar, located in Skógarströnd, is a complex of former farm buildings (a tractor shed, a cowshed, a farmhouse, and a barn) built in the 1980s and operating as such until 2001. After 12 years of falling into disrepair, the new owners brought it back to a new life by cooperating with architects from Studio Granda. Now, the buildings serve as guesthouses (former tractor shed and cowshed) and private accommodation (former barn and farmhouse). * Myndin að neðan: Dawid Franke. Preserving the character of the buildings' was the idea standing behind the renovation. That is why the primary structure, the shape, and arrangement of windows and doors, were kept. Furthermore, even though some of the roofs had to be replaced, they were not wasted. Their elements were used - the corrugated tin was used as shuttering for new concrete walls, and the timber structure was transformed into solid dining tables. The floor in the cowshed, crossed by concrete slats and steel grills, was replaced by a terrazzo floor, while the concrete slats and the steel grills were used as terrace paving and headboards in the guestrooms, respectively. Last but not least, most of the existing concrete walls remained. The materials preservation involved not only the construction materials themselves. For landscaping, earth from the site was used. Also, the manure from the cowshed was used as a fertiliser around the property in the owners' ambitious forestry project, currently scoring at around 50,000 trees and seedlings planted. The last stage of the project was renovating the old farmhouse, which was designed solely by the Drangar owners, naturally using the remaining materials left from the previous renovations. So now, only one non-restored element in Drangar – is a hay tower from the 1950s. When asked about it, one of the owners said, 'every respected guesthouse or hotel needs to have an old ruin, so we also have one'. This, however, does not mean the end of the Drangar project, as the owners are full of energy and motivation to continue developing their premises. ​ More information about Drangar: Home The CIRCON project benefits from a € 361,422 grant from Iceland, Liechtenstein and Norway through the EEA Grants and co-funding by the national funding of Poland. Co-funding from the Polish state amounts to € 54,213. 04.08.2022 Partners' meeting in Iceland After a short summer break, CIRCON started again. We started with a partners' meeting in Iceland. At the meeting, we discussed data on the Polish and Icelandic construction sectors collected so far. We also discussed real-life examples of implementing circular economy principles in construction and the main project outcome - the compendium of knowledge. Eventually, we planned our further steps.

Co-funding from the Polish state amounts to € 54,213. 15.06.2022 Can the circular economy help solve the Icelandic construction sector’s challenges? The construction sector is facing increasing pressure due to the urgent need for more housing available in the capital area and the inevitability of the transition to circular and sustainable solutions. Can CIRCON contribute to easing this burden? A small piece of information was published regarding that in Frettabladid under the link: Link The CIRCON project benefits from a € 361,422 grant from Iceland, Liechtenstein and Norway through the EEA Grants and co-funding by the national funding of Poland. Co-funding from the Polish state amounts to € 54,213. 07.06.2022 Our second working group meeting On 7th June 2022, we met for the second time. This time we discussed the role of different stakeholders in implementing circular economy principles in the construction and at which stage of building life implementing them has the highest potential. Eventually, as there is no universal definition of a circular building, we debated what it really means that a building is circular. The CIRCON project benefits from a € 361,422 grant from Iceland, Liechtenstein and Norway through the EEA Grants and co-funding by the national funding of Poland. Co-funding from the Polish state amounts to € 54,213. 25.05.2022 The first working group meeting is behind us On 25st May 2022, our working group of experts representing the cross-section of the Icelandic construction sector met for the first time. We discussed the importance of implementing a circular economy in the construction sector, the main obstacles/challenges related to that and how we can accelerate the transformation of the sector into a more circular one. In the photo, you can see our views on the primary motivations for circular economy implementation in the construction sector. Can you think of any other one?

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.
