The article discusses the possibility of using the criteria of energy saving, cost and comfort as an estimate criterion in the analysis of information modeling technologies for low-rise buildings at the stages of design, implementation and operation. The insulation systems of low-rise buildings, including frame type, are considered as an object of study. Different types of insulation systems of frame buildings are considered and, as a result, the expediency of using rolled polyethylene foam as an insulating material is established. Its use allows to form a seamless insulating sheath with minimization of heat transfer bridges, as well as to eliminate the use of additional wind-proof and vapor-insulating membranes. The regularities of the influence of operating factors on the thermal resistance of the insulating shell are established. The data obtained as a result of the implementation of experimental studies allow us to state that low water absorption and low vapor permeability of the insulating layer exclude the possibility of its wetting and degradation of heat-shielding parameters. The stability of the properties of the insulation sheath and the construction of the walls as a whole is ensured during the entire period of operation.

The article discusses the results of thermal imaging monitoring of building structures with and without insulation. Research and thermal and physical calculations showed that heat loss from the premises is determined by two groups of factors: surface loss depending on thermal conductivity, as well as vapor and air permeability of enclosing elements and heat loss at all types of joints, fasteners, etc. Thermal insulation with plate materials significantly reduces heat losses, but at the same time, heat flows through the joints between the heat-insulating plates and in the areas of their contact with other structures, necessitating the use of steam and waterproof windproof roll materials. The usage of elastic and thermoplastic materials in the insulation circuit allows minimizing heat loss at the joints between the heat-insulating elements and along the smooth surface of the wall due to the low air and vapor permeability of the material. In the systems of frame cottages, when used as a thermal insulation of rolled foam-polyethylene, it becomes possible to form a seamless insulating shell of a building. This is made possible by connecting individual sheets of polyethylene foam into a lock, followed by hot air welding. Seamless insulation systems are used both in the construction of cottages and in the construction of frame and frameless logistic facilities and housing and communal services.

The article studies one of the aspects of the heat-insulating multifunctional shells use - the cold preservation. Such task is relevant for cold storages, workshops and warehouses, in which low temperatures constant maintenance is necessary, for sports facilities (for example, ice rinks and ski facilities). In all cases of application, the main goal is to achieve the economic efficiency, which is expressed in functional results (preservation of the material that breaks down at positive temperatures) and in energy savings. The use of polyethylene-based shells, which are connected by a lock joint, is substantiated. The experimental studies results of the material given in the article shows that in terms of resistance to low and alternating temperatures, operational durability, tensile strength and water absorption, this material and insulating shells based on it are quite applicable for insulation of cold-saving objects. The experience of using heat, vapor and moisture insulating shells based on polyethylene foam with the equipment of frameless and frame structures, sports facilities, as well as for the preservation of snow at ski resorts is also provided in the article.
