This thesis undertook a whole building lifecycle assessment of a university hospital building in Trondheim, Norway designed to passive house standards. The delivered energy for electricity and heating was estimated to be 122 kWh/m2. Impacts outside the energy used during the operational phase of the building were significant including 30% of greenhouse gas emissions, 41% of terrestrial acidification and 43% of particulate matter formation. Normalized to the number of staff, the building emits roughly 0.75 tonnes of CO2 equivalents per year over the 50 year life of the building.
