Life cycle energy performances of a Net Zero Energy prefabricated building in Sicily
2017
The paper presents the energy performances in a life cycle perspective of a prefabricated building. The building was simulated in energy plus and validated on monitored data. To avoid the shifting of energy burdens from one life cycle stage to others, a Life Cycle Energy Assessment was performed. The primary energy use throughout the building's life cycle is 1,242 GJ. The materials production stage consumes the highest amount of primary energy (680 GJ) followed by the use stage (484 GJ), while the construction and end-of-life require respectively 1.7 % and the 4.6 % of total primary energy.

Energy life-cycle approach in net zero energy buildings balance: operation and embodied energy of an Italian case study
2014
Abstract The paper starts from the results of one of the six case-studies of the SubTask B in the International Energy Agency joint Solar Heating and Cooling Task40 and Energy Conservation in Buildings and Community Systems Annex 52, whose purpose is to document state of the art and needs for current thermo-physical simulation tools in application to Net Zero Energy Buildings. The authors extend the Net Zero Energy Buildings (Net ZEB) methodological framework, introducing the life-cycle perspective in the energy balance and thus including the embodied energy of building and its components. The case study is an Italian building, tailored to be a Net ZEB, in which the magnitude of the deficit…
