Extended Data Fig. 1: Spatial and temporal characteristics of FIPV generation in meeting building electricity demand.
From: Building façade photovoltaics enhance global climate resilience
a, Spatial distribution of maximum FIPV potential under the optimistic scenario at 0.25°×0.25° resolution. Insets show the dynamic diffusion (analogous to Fig. 1c), climate impacts (analogous to Fig. 1b), and annual potential for the top ten countries. Linear trends in inset time series were estimated using ordinary least squares regression. Statistical significance of regression slopes was assessed using two-sided t-tests. b, As in a, but for the conservative scenario. c, Projected global linear trend of FIPV potential under SSP1–2.6 during 2020–2050. Statistical significance was assessed using two-sided ordinary least squares regression at the grid-cell level (n = 47,175). Grid-cells with p < 0.05 are indicated. d, Absolute change in mean FIPV potential between 2046–2050 and 2020–2024 under the base scenario and SSP1–2.6 climate projection. e–f, Spatial characteristics of annual electricity demand (e) and the ratio of FIPV potential to electricity demand (f) for buildings modelled under the base scenario.
