Perspectivity of using structural insulated 3D panels in the construction on energy efficient buildings and structures

Abstract

The problem of energy dependence has been acute for all sectors of the national economy since the beginning of Ukraine`s independence. At the same time, special attention is paid to the issues of energy saving in construction and urban economy, as cities use more than 85% of energy resources. The current situation is a consequence of the deformed structure of energy consumption, the use of outdated technologies in utilities, the slow implementation of energysaving measures and technologies, and the lack of proper modernization of buildings and structures. Therefore, today the issue of researching building materials that would be energy-saving, primarily due to sealing and thermal insulation, is relevant. One of these building products is a composite building material ‒ 3D structural insulating panel (SIP). The article substantiates the possibility to using modern structural insulated panels in building. The main technical characteristics and features of the device of 3D panels are highlighted, indicators are given that confirm the relevance of this technology use in combination with the use of recuperators in construction. The basic structure of SIP panels is described in detail. The advantages and disadvantages of existing structural insulated panels are shown, both the point of view of energy saving and the point of view of the peculiarities of their use in general. It is calculated that the use of a SIP makes it possible to reduce the cost of construction in 2 times. For example, the cost of 1 m2 of the total area of the house is $80, and when fully finished, it can be $300 per m2 . At the same time, due to the high technical characteristics of the insulation, energy consumption for heating is significantly reduced. As a result of the study, it was proved that the use of SIP technology is a profitable solution, as it has a positive effect on the energy efficiency of a building due to its inherent design features. The relevance of the installation of these panels is confirmed by the fact that buildings, regardless of their purpose, have savings in energy costs in the amount of 65 ‒ 70%.
