Life cycle assessment of building integrated photovoltaics for Zero Emission Buildings

Abstract

In this thesis the life cycle of a building integrated PVs has been evaluated to estimate the life cycle CO2 emissions and other relevant impact categories of multi and mono-si wafers. The environmental impact for producing a unit square meter of BIPV multi and nono-si wafers are also analyzed. In addition, the five common types of impact categories of, Climate change, Ozone depletion, Human toxicity, Particulate matter formation and Fresh water ecotoxicity, were analyzed in view producing the functional. By comparing the life cycle assessment of the two PV types, the electricity generated by Mono-si results more of pollution compared to Multisi wafer. Moreover, PV sizing analysis has been made by considering a household functional unit. The sizing analysis has considered six poli si and one mono si PV modules.
