Information model of energy and economic efficiency of the capital construction object life cycle

The potential of energy saving can be effectively realized by combining its tools with the methods of information modelling of the life cycle of a capital construction object, which determined the problem statement of this study. In this paper, the dependence of peak and average power of heating systems necessary to maintain comfortable temperature in the building on the climatic characteristics of the construction region is determined. For the dome part, the surface of which is realized in the form of a periodic sequence of elementary cells, the dependences of heat losses through the dome part of the building on the characteristics of the cells are calculated. The parameter describing the energy efficiency of space-planning solutions is determined, and its dependences on the geometric and thermophysical properties of enclosing structures are calculated. The total energy efficiency of the space-planning solution for the heating period is calculated. It is proved that energy optimization of the life cycle is possible only on the basis of heat flows through the surface of enclosing structures, linear and point thermally stressed elements (TSE) arising at the boundary of the dome part, the boundaries of the elementary cells filling the dome and on the structural elements of the triangular hemisphere or stratodesic dome. The formulated algorithms for describing all energy flows through the enclosing structures of the building made it possible to build an information model of the energy and economic efficiency of the life cycle of a capital construction object. The constructed vector information model of the energy and economic efficiency of the life cycle of a capital construction object allows solving the following practical tasks: to determine the dependence of energy costs on climatic parameters; to optimize the composition, terms of implementation and sequence of technical measures aimed at increasing the heat-insulating properties of enclosing structures and thermally stressed elements; to determine the profitability of these measures and their payback period.
