The optimization of rail operation for improving energy efficiency plays an important role for the current and future market of rail freight services and helps rail compete with other transport modes. This paper presents a feedforward simulation-based model that performs speed profile optimization together with minor rescheduling actions. The model’s purpose is to provide railway operators and infrastructure managers with energy-efficient solutions that are tailored especially for freight trains. This work starts from the assumption that freight train characteristics are completely defined only a few hours before actual departure; therefore, small specific feedforward adjustments that do not affect the surrounding operation can still be considered. The model was tested in a numerical example. The example clearly shows how the optimized solutions can be evaluated with reference to energy saved and robustness within the rail traffic. The evaluation is based on real data from the North–South corridor crossing Switzerland from Germany to Italy.

The article is concerned with the subject of energy consumption in construction; it also discusses problems related to creation of sustainable built environment and its links to the natural environment, with special emphasis placed on its links to climate. Selected contemporary European development directions and trends in solutions using solar energy in buildings have been discussed in the paper, as well as various projects, concepts and realisations, mostly related to residential development. The collected examples present the experiences of previous eras as well as their continuation contemporary realisations based on the possibilities of using innovative technologies in architecture within the framework of actions undertaken in European countries. They are to be found in various scales referring to whole districts, housing estates and housing complexes as well as individual buildings. They refer both to new development and to transformations of the existing infrastructure in the process of its restoration.
