Use of Thermometals in Architectural Facades for the Natural Automation of Interior Temperature
Author(s): Jorge Pablo Aguilar-Zavaleta*
The growing demand for energy efficiency in the building sector, which accounts for approximately 36% of global final energy consumption (UN Environment Programme, 2022), has driven innovation in adaptive façade materials. Thermometals, or bimetallic strips, are emerging as a promising solution for passive automation of interior thermal control. These composite materials, which dynamically respond to ambient temperature fluctuations, represent a pivotal intersection between materials science and sustainable architecture, with the potential to significantly reduce reliance on mechanical HVAC systems. The methodology employed in this review analyzes the operating principle of thermometals, based on the differential coefficient of thermal expansion between two laminated metals (e.g., steel and copper). Their mechanisms of action are examined, enabling the design of adaptive fa&cce.. Read More»
