Highly transparent silanized cellulose aerogels for boosting energy efficiency of glazing in buildings

Nature Energy, Journal Year: 2023, Volume and Issue: 8(4), P. 381 - 396

Published: March 16, 2023

Abstract To maintain comfortable indoor conditions, buildings consume ~40% of the energy generated globally. In terms passively isolating building interiors from cold or hot outdoors, windows and skylights are least-efficient parts envelope because achieving simultaneously high transparency thermal insulation glazing remains a challenge. Here we describe highly transparent aerogels fabricated cellulose, an Earth-abundant biopolymer, by utilizing approaches such as colloidal self assembly procedures compatible with roll-to-roll processing. The have visible-range light transmission 97–99% (better than glass), haze ~1% conductivity lower that still air. These lightweight materials can be used panes inside multi-pane insulating glass units to retrofit existing windows. We demonstrate how boost efficiency may enable advanced technical solutions for units, skylights, daylighting facade glazing, potentially increasing role in envelopes.
