A Comparative Analysis of Traditional and New Construction Methods for External Wall Insulation in Jiangning, Nanjing, China

“…In the field of construction, particularly concerning external wall insulation, extensive research has been conducted on the comparative analysis of conventional and innovative construction methods. Several studies have explored the optimization of thermal insulation thickness for buildings in diverse climates [22] , the use of external thermal insulation composite systems with materials such as Styrofoam and mineral wool in new constructions [7]and the benefits of external insulation methods in enhancing energy efficiency and reducing life-cycle costs [23].Traditional external insulation composite systems usually entail attaching insulation materials to walls using binders or anchoring parts, followed by the application of protective and decorative layers [24]. In contrast, more recent methods, such as using thermal insulation blocks, have demonstrated significant reductions in heat transfer and energy consumption in residential buildings [5]Comparative analyses have also been conducted to decrease the thermal transmittance in traditional wall structures by employing techniques like radiant shields, low-e coatings, and insulating fillings [25].Moreover, research has emphasized the advantages of incorporating innovative materials, such as MgO-based boards, in construction to promote sustainability and energy efficiency [26]This includes benefits such as improved energy storage, enhanced comfort, and increased resistance to fire.…”

Development of TiO2–CaCO3 Based Composites as an Affordable Building Material for the Photocatalytic Abatement of Hazardous NOx from the Environment

“…The CT-4, at 74.5%, exhibits the highest MB-PDE value. It gives a clue that not only the simple synergistic effect of the two components in the composites but also the composition play an important role in deciding the photocatalytic efficiency of the prepared photocatalysts [ 35 , 36 , 37 , 38 ]. The photodegradation of MB under UV irradiation follows the pseudo-first-order kinetics, and the rate constants derived from the slopes of the linear plots are presented in Figure S1 .…”
