dc.description.abstract
Energy is a key factor for economic and societal development. However, the dependence of today’s energy systems on fossil or on other non-renewable energy sources causes a range of adverse environmental impacts. The built environment with its associated heating and cooling loads, as well as the mobility sector are major energy consumers. Therefore, assessing and understanding environmental footprints of housing and mobility is essential for the identification of strategies for the abatement of negative energy-related effects. This analysis should preferably be done on a household level, as many decisions, e.g. about the choice of private vehicles or heating systems, are taken on this level. A model for the life cycle assessment of housing and mobility of individual households was applied to quantify the energy demand of households. Space heating, hot water production and electricity were assessed using simplified energy balances and building-specific data as well as climate databases. Mobility was evaluated based on simulation results of MATSim, an agent-based personal transportation model. Mainly building upon well-established and publicly accessible databases, the model features a fast performance and an easy setup without antecedent excessive data acquisition. In collaboration with local authorities, the model was applied to the municipality of Zernez (GR), a small village in Switzerland. Primary data about housing energy demand was available in this municipality on a building level, allowing for the evaluation of the model’s performance. The results show that there is a significant inequality in the distribution of emitted greenhouse gases among households. Confirming the findings of a former study, the outcomes reveal that approximately 20% of the households with the largest impacts are responsible for about 50% of the greenhouse gas emissions induced by housing and mobility. The case study of Zernez indicates that the applied model is a promising basis for an extended assessment of the environmental footprints of households. Moreover, the analysis of emissions of individual households enables the identification of targeted measures aimed at lowering environmental impacts caused by household consumption.
