Dynamic insulation systems of building envelopes: A review
Graphical abstract Display Omitted
Highlights A comprehensive study about the integration of dynamic thermal insulation in building envelopes was proposed. Available constructions, examination approaches, and investigated parameters by the literature were reviewed. Dynamic thermal insulation savings would reach more than 40% compared to building envelopes with an equal alternative static thermal insulation. A practical zero heat loss coefficient could be achieved by employing dynamic insulation realised by airflow.
Abstract Dynamic insulation is a promising approach that allows the heat transmission rate through building envelopes to vary in a controlled mannerover time. Dynamic insulation's primary function is to change the transmissivity of the building envelope according to the actual outdoor conditions. It is applicable in almost any climate condition. The fundamental contribution of this review paper is to collect and assess available literature on this topic for different dynamic insulation structures. Therefore, this article classifies the background of dynamic (active) insulation and offersacomparative investigation of the various mathematical models, experimental studies, and numerical simulations based on the historical evolution of thermal insulating strategies over time. Several existing structures for dynamic insulation realised by airflow were categorised based on the construction type, examined parameters, and investigation approaches. Some literature results revealed that low heat loss (U < 0.1) down to practically zero could be achieved by employing a dynamic insulation air type. Moreover, the associated energy savings could reach more than 40% compared to building envelopes with a static insulation alternative. The proposed evaluation will provide basic knowledge about the development and capabilities of dynamic insulation using air and identify potential research areas to pursue.
