Abstract

Electrochromic smart windows (ESWs) provide a sustainable solution for energy-efficient buildings. However, they primarily perform dynamic adjustments on the visible and near-infrared bands with a weak control over the mid-infrared (MIR) bands and a limited energy-saving efficiency. Electrolytes are one of the most important parts in ESWs which are predominantly used to provide electronic/ionic transport. Nevertheless, the substantial potential of electrolytes in photothermal regulation is often overlooked. Herein, we developed a novel liquid flow electrochromic smart window (LF-ESW), which could not only realize an efficient solar band regulation via electrochromic materials but also fully switch the MIR emissivity between 0.19 and 0.93 by switching the absence/presence of electrolytes. The LF-ESWs could reduce the indoor temperature by 7.1 ℃ on hot days and increase the indoor temperature by 5.2 ℃ on cold days than commercial low-emissivity (low-E) glass-based windows. Moreover, they could also save building energy consumption up to 86.25 MJ m-2 than common glass-based windows and 49.532 MJ m-2 than low-E glass-based windows. This work provides an innovative strategy for dynamic photothermal regulation in buildings.

期刊介绍： Energy & Environmental Science, a peer-reviewed scientific journal, publishes original research and review articles covering interdisciplinary topics in the (bio)chemical and (bio)physical sciences, as well as chemical engineering disciplines. Published monthly by the Royal Society of Chemistry (RSC), a not-for-profit publisher, Energy & Environmental Science is recognized as a leading journal. It boasts an impressive impact factor of 8.500 as of 2009, ranking 8th among 140 journals in the category "Chemistry, Multidisciplinary," second among 71 journals in "Energy & Fuels," second among 128 journals in "Engineering, Chemical," and first among 181 scientific journals in "Environmental Sciences." Energy & Environmental Science publishes various types of articles, including Research Papers (original scientific work), Review Articles, Perspectives, and Minireviews (feature review-type articles of broad interest), Communications (original scientific work of an urgent nature), Opinions (personal, often speculative viewpoints or hypotheses on current topics), and Analysis Articles (in-depth examination of energy-related issues).
