“…Rylewski [39] proposes a system based on the same principle, but with a different implementation. Al-Nimr et al [40] propose a 'smart insulation' system for walls which is also based on fluids. Their system consists of two gaps filled with fluids and a movable partition between the gaps.…”

“…Nevertheless, none of them depends primarily on conduction. In study [31], a relevant system was developed, which according to the authors can operate both as a passive and as an active assembly. The active case is independent of the environmental conditions, and its function can be adapted easily to a building's needs, whilst the passive system requires specific temperature conditions to be activated.…”

“…Vents must be opened in the walls if these systems are selected increasing cost and time. Finally, the system with the two tanks, the movable partition and the different conductivity liquids [31], is another case of a costly system for a possible implementation on an existing building. Besides, the lack of knowledge regarding the developed hydrostatic pressures due to the building's height along with technical issues needs further research.…”

Towards the achievement of zero-emission buildings, conventional envelope solutions have started to become outdated. The concept of Dynamic thermal insulation is an innovative approach, still under development, that attracts a continuously and fast growing scientific and research interest, mainly due to its perfect alignment with the targets of a zero-carbon future. The aim of this study is to investigate a variety of such systems that are capable to adjust the envelope’s thermal resistance based on the building’s needs. The study follows a two-levelled categorization approach. Initially, the classification focuses on whether an assembly switches or varies its thermal properties within a range, whilst the operating principle is used for further categorization. The systems under investigation, are further categorized based on their adequacy as a measure for the implementation on existing buildings’ energy retrofit. This innovative categorization takes into consideration properties like operational and control complexity, mechanical equipment requirements, construction simplicity, cost, etc. The results reveal great potential for this technology and indicate a need for further investigation on issues related to their sustainability potential in new or in existing buildings.

“…However, fluids do not have a defined shape, easing the transition between insulating and conducting states, as the fluid can be transported elsewhere through pipes. Designs such as that by Al-Nimr et al [56] control conduction by changing between fluids with different thermal conductivities, as illustrated in Figure 5. In order to effectively utilize conduction as the dominant heat transfer mechanism, dynamic solid insulation material is essential, as it can inhibit or limit convection by minimizing fluid movement.…”

Topology morphing insulation enables the on-demand switching of thermal properties between insulative and conducting states through shape change. The adaptive nature of these systems allows them to regulate heat transfer by dynamically altering insulation materials or systems in response to changing conditions, including environmental factors, electrical grid dynamics, and occupant requirements. In this article, we highlight the potential of topology morphing insulation for advancing building envelope design, improving energy efficiency, and facilitating on-demand adjustments in effective thermal conductivity. We provide a comprehensive overview of topology morphing insulation, delving into its underlying principles, mechanisms, and potential applications. This review explores cutting-edge research and the potential application of insights from non-building concepts, such as nature, textiles, and origami. Additionally, it examines crucial aspects such as actuation mechanisms, effectiveness, lifecycle considerations, sustainability implications, and manufacturing feasibility. We discuss the potential benefits and challenges associated with implementing topology morphing insulation solutions. Thanks to its transformative capabilities, topology morphing insulation holds tremendous promise for advancing building envelope design, driving energy efficiency improvements, and facilitating responsive changes in effective thermal conductivity.
