One of the basic guidelines of modern architecture is designing buildings in line with the rules of sustainable development. Architecture and sustainable development refer to the process of planning, programme, design, construction and management of the building throughout the time of its existence as well as its demolition carried out with respect for the natural environment. A building designed in compliance with the guidelines of sustainable architecture is consistent with green principles and uses green solutions. Green solutions contribute to the picture of the building, which apart from proper choice of materials and technologies, its strict inclusion in the context of the place and shaping of the interior space, should also be highly aesthetic in its body. The article analyses the impact of particular green solutions on the aesthetics and the body of buildings.
