Ensuring the quality of construction and installation work while improving the energy efficiency of buildings

Abstract

The article is devoted to the analysis of the quality of implementation of one of the key measures for thermal modernization of buildings - insulation of heating system pipelines. The relevance of the topic is due to the fact that the residential sector of Ukraine consumes about 30% of energy, and its heat supply systems are mostly in unsatisfactory condition. Increasing energy efficiency through modernization is a matter of national energy security. The lion's share of projects is implemented through the "ENERGODIM" program of the Energy Efficiency Fund (since 2019), which is co-financed by IFC and GIZ and covers 40-70% of the costs of condominiums. As of November 2025, 404 projects have been completed, which requires careful control of the quality of investments. The relevance is confirmed by the adoption in July 2025 of the State Target Program for Thermal Modernization until 2030.

It has been established that insulation of pipelines in unheated premises (basements, technical undergrounds, attics) is a highly profitable measure. At the same time, even during its implementation, a number of significant shortcomings are recorded. One of the reasons is the sharp decrease in qualified performers due to the defense of the Fatherland. The paper analyzes the specifics, advantages and disadvantages of key thermal insulation materials (foam rubber, foam polyethylene, polyurethane foam, polystyrene foam, mineral wool).

Based on the audits, five typical defects are systematized: uninsulated end of the insulation; poorly insulated insulation (gaps, loose fit); insulation with unsuitable materials; damage to the insulation during installation; insulation with materials of unsuitable (insufficient) thickness. It is shown that the first four defects arise due to negligence and ignorance of the technology and are eliminated by control. The fifth defect is associated with ignorance of the DBN norms. The problem of further mechanical damage to thermal insulation (by cats, birds) is separately highlighted and protection methods are proposed (access restriction, installation of protective casings - PVC, aluminum, fiberglass).

Pipeline insulation is an important stage. The industry is experiencing an acute shortage of qualified personnel. Most of the identified shortcomings can be easily eliminated through more thorough control and detailed familiarization of the performers with the technology of work and regulatory documents.
