Does PV glazing reduce building energy use?
Although a transition from single-pane to code-compliant glazing improves building energy use from 22% to 25%, PV glazing with a PCE as low as 6% reduces energy use by more than 30% (Figure 4 C). More than 30% energy use reduction is realized across PV technologies. Increasing PCE reduces building energy use even more.
