This paper, titled 'Energy saving potential of advanced dual-band electrochromic smart windows for office integration', explores the energy efficiency and comfort benefits of spectrally selective dual-band electrochromic windows, also known as 'Plasmochromic', in building design.

A simulation analysis of a simplified office model in five European climate zones (Sevilla, Barcelona, Turin, Berlin and Helsinki) compares dual-band electrochromic glazing with advanced commercial glazing systems.

Two control strategies—rule-based and model-based—were used. Results show that dual-band electrochromic windows, with intelligent control, reduce annual energy consumption by up to 27% for heating, cooling, and lighting, and cut visual discomfort by 32%, making them a more sustainable and comfortable option compared to traditional solar control glazing systems.
