Geometric modeling of integration of solar energy in high-rise bio-climate buildings

Abstract

A feature of high-rise buildings is their high energy consumption compared to buildings of lower height. The use of solar energy can reduce the energy load. An urgent task is to develop tools that can justify decision-making on the feasibility of integrating solar systems in the energy-efficient design of high-rise buildings.The article discusses the methods of geometric modeling in determining the effective solar radiation on the surfaces of high-rise bioclimatic buildings. The design of bioclimatic high-rise buildings is based on the principle of their maximum adaptation to the natural environment, which is considered at three levels: macroclimate, mesoclimate and microclimate.In geometric modeling of the integration of solar systems into a high-rise bioclimatic building at the macro level, a primary analysis is carried out regarding the potential of solar radiation in accordance with the geographical location of the high-rise buildings on the planet. Application of the geometric model of the diurnal cone of solar rays Φ, which was proposed by prof. А. Podgorny allows you to analyze changes in the duration of solar exposure for a given day of the year when changing the geographical location of the construction site on the planet.Geometric modeling of heliosystems at the meso and micro levels analyzes the potential for solar radiation of a high-rise building in accordance with its shape, position and shading. In the article, it is proposed that zones of effective solar radiation on the surfaces of tall buildings be determined by geometric modeling of the zones of formation of intrinsic and incident shadows, taking into account the dynamics of sunlight. Zones of constant, variable lighting, constant shading on the surface of a high-rise building determines the location of the rational arrangement of solar systems.
