Introduction of Clusterization Principles in the Solution of Problems of Energy Efficiency and Ecological Safety of the Existent Building Fund

Abstract

The aim of the work is to introduce clusterization principles in the solution of problems of energy efficiency and ecological safety of the existent building fund. The material of the research is the process of modeling of energetically effective architecture-building clusters. In this sense it is topical and expedient to elaborate technologies and schemes, able to support making decisions as to the formation of energetically effective architecture-building clusters. The main attention is paid to the solution of infrastructure problems of energy saving of the architecture-building branch, connected with the absence of universal models, distinct algorithms of the formation of energy efficiency clusters and reliable instruments of their activity optimization. But realization of advantages of energy efficiency clusters is possible only at introducing effective mechanisms of the formation of a structure, able to provide a result, optimal by an energy efficiency criterion. The work offers a scheme of the formation process of such structure. The synthesis of models of energetically effective architecture-building clusters is based on principles of the systemic construction of geometric models and provides the imitative modeling of different development scenarios of synthesized clusters. At this stage of the research a function of making decisions as to the real cluster formation is left for experts. But an algorithm of the synthesis of models provides the formation of a knowledge base that will be in further a base of an “internal model” of the intellectual system of supporting decisions making, elaborated for modeling cluster structures. The scientific novelty of the work is in the elaboration of theoretical bases of the technology of coordinating the structure with object properties.

Definition of the daily model of distribution of solar radiation on the curved surfaces of buildings

“…Substituting the values obtained from ( 3), ( 4) into ( 1) and performing the appropriate calculations, let's find the amount of solar radiation arriving at one calculated point on the surface from 17 positions of the Sun on the solar trajectory. Substituting the values obtained from ( 3), ( 4) into (1) and performing the appropriate calculations, let's find the amount of solar radiation arriving at one calculated point on the surface from 17 positions of the Sun on the solar trajectory. That is, let's obtain 17 instantaneous values of the amount of solar radiation at one calculated point А і,ј , fences for the calculated period of time, adding them let's obtain the average daily value of the amount of solar radiation at the calculated point А і,ј , fences.…”

“…The instantaneous value of the amount of solar radiation arriving at the point A i,j of a discretely given surface Φ from the k-th position of the Sun on the daily solar trajectory ( , ) k N ⊂ 1 (Fig. 1) and is determined by (1). (…”

“…With a sharp reduction in the reserves of non-renewable energy sources and a growing tendency to increase the demand for energy resources, there is a need to use renewable energy sources. As noted in [1] the use of renewable energy sources can partially, and at some facilities and completely replace the use of traditional (non-renewable) energy sources. One of the most widespread sources of renewable energy is solar energy, the use of which raises the problem of predicting its arrival on the surface.…”
