Torfhús - getum við lært af fortíðinni? About the project In the preliminary study done in 2024, we analysed the climate sustainability of turf houses by performing a life cycle assessment (LCA) for a model turf house and estimating its carbon footprint throughout its whole life. This gave us a baseline for addressing the following question: Could we learn from the past and change our ways of living and building inspired by turf houses? In this project, we'll investigate past techniques, attitudes toward material use, and living conditions we could adopt to current practices. Within the project, we'll also work on designing a circular house that can be built in Icelandic conditions. Eventually, we'll compare the carbon footprint of a modern circular house to that of a model turf house. Grænni byggð works with Lendager Island and Minjastofnun in this project. Collaborators Overview The project's objective is twofold. It aims to facilitate circular construction in Iceland by providing a proof-of-concept in the form of a circular house design and, simultaneously, bringing attention back to a vital part of Icelandic heritage: turf houses. The project received a grant from Askur - mannvirkjarannsóknasjóður which is funded by Húsnæðis- og mannvirkjastofnun, Ministry of Social Affairs and Housing and the Ministry of Culture, Innovation and Higher Education.

Nýting gagna fyrir grunnviðmið kolefnisspors vegna losunar frá verkstöðum About the project The aim of the project Nýting gagna fyrir grunnviðmið kolefnisspors vegna losunar frá verkstöðum is to provide updated average values for phases A4 and A5. During the certification process for buildings, data on emissions from construction is collected. This data is mostly used for compliance and documentation, but has so far not been used to improve the accuracy of baseline criteria. The Icelandic average values given for phases A4 and A5 are 19.79 kgCO₂-ig/m² and 42.5 kgCO₂-ig/m². These values are based on Icelandic life-cycle assessments that were available in 2022, but not many were available. Vegvísir að vistvænni mannvirkjagerð states that the aim is to reduce emissions from A4 and A5 by 70% by 2030. Updated average values for emissions from construction sites contribute to achieving these goals – both in the context of Iceland’s commitments and within individual projects. More accurate data makes decision-making more purposeful and makes it easier to clarify where the greatest reduction in emissions is possible. Such work can also be an incentive to improve accuracy in other phases of life cycle assessment. 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.

Online Event and Report An online event was held to promote the publication of a new report on the status and prospects of emission-free construction. There, we also introduced the Nordic network of collaboration and displayed the video from the site visit to the Green Construction Site of the Future. Volvo CE and SiteHub talked about their way towards emission-free construction sites. Recording of the event: https://www.youtube.com/watch?v=PNRE0HAhaSw Read the report: https://www.norden.org/da/node/79878 Testing of a battery-electric excavator in Oslo Emission-free excavators have been tested in three different construction sites in Oslo in the last year. In a new report from SINTEF, the results are summarised. The electric excavators from Nasta ran for a total of 6817 hours and saved NOK 372 000 in energy, and emission reductions were in excess of 91 tons CO2. Read the report here.
