Opis:
The aim of this paper is to investigate the environmental credentials of steel buildings and to present the environmental impact categories and values in a steel housing activity through a case study of steel office building. In this framework, a life cycle assessment (LCA) methodology was applied, which provides an understanding of the overall environmental performance of a housing construction. The relative influence of the service lives of different building components compared to the energy use of the buildings with a different energy efficiency is presented. As the analysis showed, recycling of construction waste becomes a critical issue, which can ensure a number of environmental benefits. The aim of this research activity was also to point out the need for an integrated approach in the design process, combining environmental performance assessment with structural calculations. Environmental impact assessment of the construction activity was carried out, following the inventory listing, in order to reach to useful conclusions on the environmental study of the project. Although steel and concrete proved to be responsible for the negative environmental impacts the ability of reuse and recyclability of steel has decreased the negative impacts of steel construction on environmental burdens.

Opis:
The paper is devoted to some problems connected with last modification of EU directive on energy efficiency, viz.: free choice of the measure concerning the improvement of energy efficiency, i.e. final or primary energy consumption, corresponding energy savings or energy-consumption index; however without cumulative consumption or cumulative savings of primary energy. In EU directive it has been stressed the importance of measurements systems (reliable measurement information); but has not been recommended any advanced validation of measurements results, nor energy auditing or algorithms of calculating the energy savings due to improvement of energy efficiency concerning large industrial plants. Evaluation of complex buildings should be realized by means of the system method (input-output analysis). The separate problem is devoted to application of thermo-ecological approach in the analysis of complete results of improving the energy efficiency. Human activity is connected with the depletion of nonrenewable resources, including primary energy, due to not only production of consumer goods but also the necessity of compensating the unfavourable effects of harmful emissions from energy-technological processes. Therefore the index of energy-ecological efficiency has been proposed as the most competent evaluation of improvement energy efficiency of production processes and systems.

Opis:
Nowadays, increasing number of machines and off-road vehicles are equipped with elastomeric, mainly rubber, tracked chassis. Rubber tracks and belts combine the most important advantages of both: pneumatic tires and conventional tracks made from metal links. In spite of significant benefits, rubber tracked chassis is a novel and uncommon design solution, as the application of rubber tracks and belts still brings up many severe problems. Consequently, an urgent need to overcome these problems exists. In The Division of Off-Road Machine and Vehicle Engineering (DORMVE) an intensive research, pertaining to rubber-tracked chassis has been conducted for many years. In the very beginnings, the investigation was carried on in cooperation with German companies INTERTRACTOR, IAMT and IBAF. As a result, numerous original and innovative design solutions, which became a subject of European, American and Japanese patents, were developed. However, some issues have not yet been resolved. Present research of DORMVE is aimed at identification of problems concerning energy efficiency of rubber-tracked chassis. The main objective of current investigation is to improve the energy efficiency. To do so a comprehensive optimisation process is to be carried out. Within the following article, a classification of aforementioned problems will be discussed. Research facilities in laboratory of DORMVE and exemplary results, which have already been obtained, will be also presented.

Opis:
Manufacturing engineering is supposed to provide analyses related to various aspects of manufacturing and production in order to maximise technological, energy, and economic gains in relevant production processes. The present paper gives a recapitulation of several publications by present authors, presenting considerations of the energy efficiency of biofuel production. The energy efficiency is understood as the ratio of energy obtained from biofuels produced basing on crops from a particular area to the energy required to satisfy needs of all subsidiary processes assuring correct functioning of the production system, starting from operations aimed to obtain agricultural crops, and ending with the conversion of the crops onto biofuels. Derived by the present authors, the mathematical model of energy efficiency of biofuel production is extended to a more general form, and applied to the analysis of quantitative relations between energy efficiency of sc. “energy plantations”, and further elements of biofuel production system converting harvested biomass into biofuel. Investigations are aimed towards the determination of the role of biomass as a source of energy.

Opis:
Energy efficiency is not only energy yield related to the energy consumption in a specific device or building but also the possibility of optimal use of the stored energy in a determine area or in the system, without the necessity for its transmission. Generation, distribution and balancing of energy demand, in a limited area, becomes an energy cluster in which, under the agreement of the entities forming the cluster, there is a possibility for effective management of energy produced and its storage, according to the requirements and assumptions of the capacity market. The purpose of such an initiative is primarily the effective development of distributed energy, which does not have to be based solely on renewable energy sources, but can also use conventional sources, according to dedicated management models. The whole project is intended to improve energy security, have a positive impact on the environment, strengthen the local economy and generate lower costs for the end user. According to the RES Act, a member of an energy cluster can be an enterprise, a natural person, a local government unit and their organizational units. It can also include small, medium and large public transport companies and other entities functioning in the area covered by the energy cluster. A cluster initiative may be established and operate in an area no larger than five municipalities or one county, and its purpose is to obtain financial and non-financial benefits for the members of the energy cluster.

Opis:
Aim: The aim is to recognize the main determinants of the energy efficiency improvement in transport in Poland in the years 2000-2014 using structural and index decomposition analysis, and to identify areas where there is still potential for further reduction of energy consumption. Design / Research methods: Techniques used to analyse changes in energy use are: structural decomposition analysis and index decomposition analysis. Each of these two methods is characterized by distinctive, unique techniques and approaches, as they have developed quite independently. Index decomposition analysis measures the impact of energy efficiency gains on the level of energy consumption, at the most detailed sector disaggregation level allowed by the available data. Whereas structural decomposition analysis allows to analyse the impact of the external factors, such as technological, demand, and demographic effects, on the fluctuations of the total energy consumption. The similarities and differences between the two approaches are summarized and illustrated with a numerical example of Polish transport. Conclusions / findings: The article recognizes the main determinants of the energy efficiency improvement in transport sector in Poland in the years 2000-2014. In case of Poland ODEX shows an overall progress of energy efficiency in transport by 24.3%. Results obtained with decomposition analysis indicate large divergences in energy efficiency improvements between modes of transport and vehicle types and identify areas where there is still potential for further reduction of energy consumption. Results from decomposing structure of energy use, show activity effect to be main reason for energy use growth. The distribution of each mode in total traffic of passengers and goods changes toward less energy efficient modes. The only factor driving down the energy use is energy savings.Originality / value of the article: Using two methods of decomposition analysis and comparing obtained outcomes allows to get a broader view on energy use trends. Results presented in this article are a good starting point for further detailed analysis of changes in energy use of transport.

Opis:
The Turkish Merchant Shipping Industry has recently witnessed an increasing awareness of the importance to minimize environmental pollution and fuel oil consumption. Together with certain non-governmental organizations and media concerns about environmental protection, the International Maritime Organization (IMO) has been strict on controlling undesirable effects on the environment and, consequently, forcing shipping companies to minimize their emissions. Besides, today’s highly advanced technology companies over the world have developed various innovative systems that can be utilized to minimize carbon emission, thus giving assurance to relevant investors that their investments are most likely to turn out well with a considerable financial gain in the short or long term. Despite all such favorable developments, in a general look, shipping companies seem reluctant in making use of technologies providing efficiency in energy consumption. This reluctance has eventually brought about the term “Energy Efficiency Gap”. This research conducts a questionnaire, created by Acciaro et al. [1], among the shipping companies in Turkey. 20 respondent companies, who represent 26 percent of the Turkish owned merchant marine fleet of over 1000 gross tonnage in terms of deadweight cargo capacity, participated in the research. The Pearson correlation analysis was used, and interpretations were made according to the obtained statistical values. The aim of the research was to identify reasons and points restraining the use of new technologies regarding energy efficiency, as well as to develop proposals for the innovators in this field about how to overcome this handicap concerning technical and managerial aspects of gaining energy efficiency.
