Title: Evaluation of the material requirements in Miljöbyggnad 3.0
Authors: Hagman, Louise

Abstract: The construction sector accounts for a large part of the greenhouse gas emissions that are released in Sweden each year. Within the sector the environmental focus has up until recently mostly been about decreasing the need for energy during the operation phase. However, now with more energy-efficient solutions, the focus has shifted more towards decreasing the negative impact caused by building materials. This change can clearly be seen in the Swedish environmental certification system Miljöbyggnad, which puts significantly higher demands on the material indicators in their last version, Miljöbyggnad 3.0. This has resulted in questions among the actors who use it. With this background the aim of this report was formed. Evaluating and clarifying what the new material requirements in Miljöbyggnad 3.0 mean for the actors in the construction sector. The report should answer if the market is prepared to meet the demands of materials and services needed to reach grade gold in the three material indicators. To answer this, the current state of knowledge has been investigated. Looking at what has been written about the sector’s view on environmental certification, as well as what is currently being discussed regarding the three material indicators; documentation of building materials; phasing out hazardous substances; and the climate impact of structural framework and foundations. Furthermore, to connect the literature to reality a case study was performed, including interviews with people related to a particular project. From the study it was shown that there are different opinions among the actors, regarding the consequences of this new version. What is shown to be questioned the most are non-documented building materials and uncertainties around the indicator considering the frame and foundation. Some actors think the requirements in this particular indicator could be presented more clearly, and that the requirements regarding EPDs (environmental product declarations) are not connected to reality. Mostly, this concerns the concrete industry, which due to having many recipes for their concrete, finds it difficult to fulfill this requirement. Two suggestions for how this issue could be handled have been stated during the interviews, and now the decision-makers of the system have to form an opinion regarding those. Finally, from the report it can be concluded that it is possible to reach grade gold in indicator 13 and most likely in indicator 14. As for indicator 15, the market is not in line with the requirements. Thus, today it is not possible to reach grade gold.
