Hybrid life cycle assessment at the neighbourhood scale: The case of Ydalir, Norway

The focus of this study is Ydalir, a neighbourhood in Norway currently in the early planning stages. Ydalir aims to produce its energy locally based on renewable sources, has passive house standards or higher for all its buildings, uses timber or other materials with low embodied greenhouse gas emissions (EGHGE) as its main building materials and prioritises low emissions solutions for the mobility of its inhabitants. Because of those characteristics, the EGHGE related to the operational phases at Ydalir will be low and the relative importance of the EGHGE related to the materials will increase. The EGHE at Ydalir should thus be quantified in a comprehensive manner.
