Prospects of designing small architectural forms using alternative energy sources

Abstract

The energy efficiency of the transport system is one of the key issues in the concept of sustainable development of modern cities. Increasing energy efficiency in the transport sector implies increasing the efficiency of the entire transport sector: from modernizing vehicles to introducing energy-efficient comfortable stops for public transport into the city system. One of the problems of modern architecture of large cities is the creation of a unified architecture of small architectural forms (SAF), namely, stops of urban public transport. They should not only have a modern design, but also be comfortable, functional, safe and energy efficient. In the article, the authors propose a unified urban archetype for an energy-efficient public transport stop for the city of Kyiv. Energy efficiency is achieved by installing solar panels on the roofs of the SAF. During the placement of the bus stop, it is imperative to take into account the shading from nearest buildings located on the south, south-east and south-west sides. Depending on the orientation of the roof of the stop to the cardinal points and the type of solar panels, it can generate about 2030 kW∙h/year (west orientation) – 2269.9 kW∙h/year (south orientation) of electricity. The maximum deviation from the averaged equal-percentage value (2143.16 kW∙h/year) related to the actual data between the maximum and minimum of generation is only 5.55%. This is explained by the angle of photovoltaic panels, which is optimized for universal use. The proposed archetype is energy efficient, functional, and therefore can be taken as a basis for mass placement in the city.
