The Energy-Efficient Heat Insulation Thickness for Systems of Hinged Ventilated Facades

Abstract

Calculation of payback periods of the energy saving actions directed on increase of level of thermal protection of external enclosure structures of buildings is given. Economic efficiency of investments in energy saving actions is analyzed and the model allowing to carry out the specified analysis is offered. Recommendations about reduction of payback periods are provided.Article also is devoted definition of optimum, economically well-founded thickness of a insulant in systems of rear ventilated facades. Are resulted thermotechnical and economic calculations. The optimum thickness of the insulant in the given systems is offered.A number of the energy saving actions is necessary for economy of thermal energy, allowing to eliminate defects of protecting designs or to reduce their influence on building heatconsumption. Construction of hinged ventilated facades at simultaneous introduction of automated individual thermal points with automatic equipment dependent on weather [1] can become an example of the engineering decision on increase of heat-shielding properties of protecting walls.
