In recent years, advancements in facade technology have focused on enhancing thermal insulation and airtightness to reduce building energy consumption. 

Standard systems aim to ensure comfort in typical conditions but, to further cut energy usage and contrast the climate crisis, facades must excel in all environmental situations. This is the purpose of adaptive facades.

A recent paper in Building & Environment examines testing protocols for opaque adaptive facade systems, noting variations in setup and procedures among reported tests. 

The study highlights the need for comprehensive testing to fully understand dynamic thermal performance, and, moreover, it suggests how to develop more complete procedures.
