Special Issue Information

Dear Colleagues,

As the assembly of building structures exhibiting weak thermal behaviour is on the verge of extinction, it is essential to identify the key strategies and methodologies that allow us to succeed in this critical goal. In light of this necessity, and as the threat of climate change greatly influences our way of thinking, it seems that one of the most rational ways to enhance the thermal defensiveness of building envelopes is to use thermal insulation materials. Yet, as we delve deeper into the core of this problem, it becomes clear that recent developments in insulation materials should be justified with great caution, as there are still a number of unexplored areas that need to be clarified in addition to any potential thermal benefit. Thus, there are several crucial factors that should be taken into account while assessing insulation materials holistically (protection in terms of moisture, heat, fire, and soundproofing). Along with this, environmental issues and potential health risks associated with the usage of insulating materials might be extremely important. Based on these considerations, it is evident that an insulation material's performance and the properties that it displays are closely linked.

This Special Issue's specific goal is to fill the knowledge gap about potential approaches to raising building shells' overall energy efficiency by reducing the exchange of heat through the use of thermal insulation materials. In addition, an in-depth analysis of insulating material performance is intended to be provided. On these grounds, the current research initiative invites the submission of manuscripts that concentrate on the properties, performance, and applications of thermal insulation materials (conventional or dynamic insulation systems), as well as the significance of other advanced materials (such as phase change materials and geopolymer materials) that serve as sinks or even as barriers against the progression of heat. A particular emphasis should also be placed on the adoption of forward-thinking building approaches in terms of nanotechnology for thermal energy efficiency systems and the embracement of novel methods of construction capable of supporting cutting-edge technologies in building design. In this vein, research studies proposing complimentary experimental and numerical approaches are strongly encouraged. It should be noted that this Special Issue welcomes both original research articles and reviews. We look forward to receiving your valuable contributions.

Climate change is compelling countries to alter their construction and urbanization policies to minimize their impact on the environment. The European Union has set a goal to reduce greenhouse gas emissions by 55%, recognizing that 50% of its emissions originate from maintaining thermal comfort within buildings. As a response, the EU has developed comprehensive legislation on energy efficiency. In this article, special mortars using aerogel, perlite, and vermiculite as lightweight aggregates were prepared and studied to enhance the thermal properties of the mortar. Their thermal properties were examined and, using a solar simulator for both hot and cold conditions, it was found that varying proportions of these lightweight aggregates resulted in a mortar that provided insulation from the exterior up to 7 °C more than the reference mortar in warm conditions and up to 4.5 °C in cold conditions.
