The greenhouse effect and overall climate changes are the main reasons for developing ecological powertrain units dedicated to road vehicles. An electrical drivetrain without using conventional combustion engines fueled by hydrocar-bon fuels is an effective method to significantly reduce CO2 emissions from the fleet. It is particularly vital in 2020 emis-sion regulations aspects, and continuously the number of vehicles increasing. In this paper battery electric drive system of a small size passenger car was analyzed in terms of two different drive modes in cooperation with two recuperative braking modes. The research was carried out with real driving condition test requirements and driving parameters re-cording. Based on data obtained from OBD signals, energy flow and torque distribution have been specified. In results, overall reducing energy consumption has been achieved with ECO mode compared to normal mode. Selection of the driving mode ECO has a positive impact on reducing the state of charge saving more than 5%, taking into account the whole RDC test; greater energy consumption reductions were observed in selected test areas.

Modern Building

Building with earth is widespread and still mostly based on traditional experiences. Increasing demandsin energy consumption reduction during the construction and exploitation of buildings put more andmore in the focus the good features of houses built with earth.Testing of earth mixtures with othernatural materials showed that it can get even a quality of bricks, which indicates the lack of appropriatestandards for this type of construction.Testing are performed with mixes of earth and straw intended forrammed earth and adobe construction.This method of preparation and construction applies in alternate construction with straw bales and it isalso used in the construction of prefabricated panels with wooden frame filled with a mixture earth andstraw where it is possible to build prefabricated structures or as a filling of wall screens in skeletalstructural system of larger dimensions and number of floors.Laboratory tests have shown that the mechanical and thermal properties of this material fulfilled thehigh demands for the construction of modern buildings. Based on the presented results it can proceedthe development and testing of structural elements for that kind of building.Also, based on results, in the article the authors presented possibilities of architectural design ofvarious building possibilities of objects, as practical examples of prefabrication applied in somecountries.
