Abstract

Abstract. Raising of problem. Nowadays more and more normative documents aimed at providing energy efficiency of construction objects are developing in Ukraine, they are trying to fit in the European norms. However all the same the European countries which already introduce the standard of passive and even active house which not only completely provides own energy consumption, and also realizes the state the made excess energy are ahead of us. Effective external thermal insulation remains the traditional decision for achievement of standard level of thermal protection of buildings. However, it is known that almost each building, warmed from the outside compliance with existing rules, contains heat-conducting inclusions, breaking heattechnical uniformity of an insulating cover of the building and represent a zone of the increased heatlosses. By specialists of MSW department versions of the device of energy saving constructive technology solutions for elimination of negative effect of heat-conducting inclusions in a balcony zone have been developed. Operational efficiency of these decisions is investigated in the previous publications. Norms of costs of work of the device of the proposed solutions aren't presented in modern normative documents in the field of construction. Therefore relying on the norms of time found when carrying out time researches of productions of the device of additional thermal insulation of heat-conducting inclusions of objects of the housing estate us the expediency of introduction of improved versions of the device of additional thermal insulation have been analysed from the technological and economic point of view, we calculated labor input and the cost of the device of thermal insulation of balconies for 20 buildings with various architectural and planning characteristics. At the same time for each building four options of additional thermal insulation and option of external thermal insulation have been applied to balconies. Analysis of recent researches: Technical and economic indicators (labor input, cost, duration) the device of additional thermal insulation the reinforced heat-insulating blocks aren't investigated by almost domestic experts. Therefore, the purpose of this work is the assessment of the improved versions of the device of additional thermal insulation optimized by criteria of decrease in labor costs and cost in comparison with similar indicators of the device of external thermal insulation. Conclusion: Results of our research demonstrate that application of additional thermal insulation allows to reach almost identical (with a difference in 1-4%) economic effect in comparison with the standard device of external thermal insulation of balconies. At the same time devices of the developed constructive technology solutions costs about 4 times cheaper. On labor input, devices of additional thermal insulation, for example, for an object of a research № 1 there correspond to an indicator 21 persons- h while devices of external thermal insulation of balconies of this building corresponds to work expenses in 5401  persons - h.
