Environmental Analysis of Integrating Photovoltaics and Energy Storage in Building

The energy consumption of buildings accounts for approximately 36 % the final in Europe, being largest end-user. UK government has committed to cut greenhouse gas (GHG) emissions by 100 below 1990 levels and bring all GHG net-zero 2050. To support realisation these goals concept an Active Building was formulated which refers any building type, such as factories, offices, homes, other structures built environment, are equipped conserve, generate, store, release energy. increasing deployment rooftop photovoltaics drives growth storage capture solar later use buildings. Office at Swansea University, 2018 is a two-story office building. Its demand, including that electric vehicle charging, primarily met 23 kWp building-integrated (BIPV) 110 kW lithium-ion (Li-ion) batteries. When BIPV batteries unable meet electricity supplied from grid can be used. objective research assess potential environmental impacts system Li-ion batteries, well address lifetime degradation associated consequences. Life cycle assessment (LCA) employed this research. Three operational strategies designed regarding interactions between electrical grid, BIPV, In best case scenario, using rolling average predict generation consumption, GWP operation 33 g/kWh 5 fold reduction compared with 170 g/kWh. worst strategy creates 128 g/kWh, it still improvement upon supply national alone. This analysis demonstrates optimisation reduce
