Transparent wood composites (TWCs) have 15% the thermal conductivity of silicon-based glass and can be used in alternative glazing systems. Single-paned and double-paned TWC based window assemblies were developed for implementation in commercial reference buildings of three vintages (Pre-1980, Post-1980, and Post-2004) located in 15 climate zones. Energy simulations were performed for baseline buildings and compared against buildings with TWC based glazing systems in place of traditional glass based glazing. In addition, a cost analysis was performed for lab-scale production of TWCs. Results showed that buildings with TWC based windows reduced space conditioning by up to 33.3%. Commercial buildings with high window to wall ratios saw the largest energy savings. Climate zones that are moderate and do not have high annual solar radiation tended to also spend less energy on space conditioning. Yet, some building types such as hotels saw increases in space conditioning energy needs as a result of TWC based window implementations.
