Studies of thermophysical parameters of modular facades

Introduction. A literature review of approaches to the development and testing of energy-efficient modular facade systems is presented. It is noted that methods for designing modular facades are particularly relevant in extreme climates, where thermal performance is the principal parameter to be improved.

Materials and methods. The literature review was conducted using both Russian and international sources. The literature review included Russian articles published in journals listed by the Higher Attestation Commission (VAK list), as well as international publications indexed in major bibliographic databases and available through MDPI, ScienceDirect, Wiley Online Library, SpringerLink, and Scopus.

Results. The studies by J. Li et al. on the selection of thermal insulation materials, the work by A. Scioti et al. on the optimization of connection joints and the composition of structural mixtures, and the work by X. Zou et al. on structural connection solutions that preserve factory-applied finishing were reviewed. For experimental verification, S.P.B. Sousa et al. described test methods under dynamic laboratory conditions, while the paper by Z. Azkorra-Larrinaga et al. addressed partially simulated full-scale conditions.

Conclusions. Vacuum insulation panels are considered the most effective thermal insulation materials, reducing heat losses by approximately 73–76 %, while aerogel coatings provide savings of about 43–49 %. A system of internal ties has been proposed for the design of modular facade connections. In addition, S-shaped connecting profiles are used as an effective structural solution, reducing the temperature difference between expanded polystyrene panels from 8 to 1.5 K. Modular facade systems are best verified by combining laboratory methods with full-scale tests.
