Overview of the use of energy-saving technologies in building

Abstract

The purpose of the current research is to review the technologies of a phase change material application. The principles and peculiarities of the operation of a material with a phase change have been studied. Experimental studies conducted by Nan Yu, Chao Chen, Khamid Mahkamov, Irina Makhkamova, Qiong Li and Jing Ma based on the method of curing of precast concrete elements under fallow have been described. The research methodology proves the effectiveness of the application of materials of this kind in the construction industry. The options for using wall panels with a phase change material inside the construction have been considered. The study of the wall model with a phase change material namely paraffin in the enclosing structure conducted by such author as Babaev B.D. is presented. The calculation method for the system introduced by the researcher for assessing the effectiveness of passive heating obtained from the original construction has been studied. A comparative analysis of constructions with heat-retaining materials such as a building envelope with a phase change material and a concrete floor was carried out. A method of climate forecasting that makes it possible to choose the most rational passive strategy for the future use has been studied. The possibilities of using bioclimatic maps and the Givoni’s chart for analyzing weather conditions and evaluating the efficiency of using a particular energy-efficiency system have been considered.
