Increasing relevance of the problem of energy conservation and use of alternativesources of energy in connection with global and local resource crises led to the formation of adeveloped system of international standards in the field of energy management, which is aimed atregulating and disclosing the content of the principles of energy efficient processes and development.Rational policy in enterprises of various industries and the implementation of energy-savingmeasures, particularly in the maritime transport. The dynamics of implementation of projects aimedat increasing the efficiency of energy use is growing steadily at different levels and in different sectorsof industry. It is widespread in the fields of design, modernization and reconstruction of energyefficient buildings and structures, construction of industrial infrastructure elements, technologicalproduction processes. Implementation of such projects is a priority line of activity for enterprises andcompanies of various types of economic activity. Accordingly, the leading sectors of industry develop strategies to improve environmental safety and energy efficiency - ship navigation is no exception.Indeed, the process of increasing energy efficiency is achieved by reducing fuel consumption, whichwithout exception leads to a reduction in the amount of waste products discharged into theatmosphere. Therefore, the problems of energy efficiency in order to increase requirements forenvironmental safety of transport and increasing responsibility of shipowners become the centralobject of research of current theory and practice of operation of maritime transport means. Anotherurgent issue is the improvement of universal principles of energy efficiency within the framework ofindividual ship-owning companies and the development of tools for economic analysis of energyefficiency of the own fleet, search for new ways to form professional competencies of shipcrewmembers in the field of energy conservation.

<p>Related to climate change and economic development of environmentally friendly (green economy) issues, the President has committed to reducing emissions of greenhouse gases (GHG) by 26% on their own sources (BAU), and up to 41% with international support in 2020 through Presidential Decree No. 61 in 2011 about the National Action Plan for Greenhouse Gas Emission Reduction (RAN-GRK). In addition to regulating the sectors that are considered to be the largest contributor to GHG emissions, the regulation also establishes funding sources RAN-GRK either through the APBN, APBD, as well as a variety of other sources constituted under the legislation. One of the initiatives that need to be supported is an effort to reduce their energy use. In this context, the Ministry of Finance has provided various forms of incentives to affect various economic actors in order to implement energy savings programs through the Special Allocation Fund (DAK) Energy Efficiency (EE) in the mechanism of Transfer to Regions. DAK-EE is expected to occur in energy efficiency projects aimed to (1) reduce electricity subsidies, (2) encourage the use of energy-efficient technologies, (3) stimulating the involvement of the financial sector (banking / financial institutions) to support the development of energy conservation and, (4) assist efforts to achieve national GHG emission reduction target by 2020. Using the descriptive method of analysis, the researcher wanted to analyze the possible use of DAK EE as a energy efficiency financing in Indonesia.</p><p><strong>Keywords</strong>: Special Allocation Fund, Energy Conservation, Energy Efficiency</p>

Consider ways to stimulate heat and energy conservation in Ukraine and other countries, based on an analysis of the legal framework and practical experience. Review and analysis of the Energy Strategy of Ukraine for the period up to 2035 “Security, Energy Efficiency, Competitiveness”, Laws of Ukraine “On Energy Saving”, “On Energy Efficiency Fund”. Review and analysis of the practical experience of applying different ways of stimulating energy saving, improving the efficiency of use of fuel and energy resources by economic entities, consumers in the housing sector in Ukraine and other countries. The ways of stimulation of heat and energy conservation in Ukraine are proposed, which envisage both the system of financing of projects of resource saving and ways of informing consumers about the energy efficiency of new equipment (through marking), buildings, households. The main directions to be developed for efficient management of energy efficiency projects, in particular, the efficient functioning of district heating; combined production of thermal and electric energy; use of local renewable energy resources; introduction of resource-saving eco-friendly technologies. The legislation, which provides financial and informational ways of stimulating energy and heat conservation, as well as ways of financially filling the energy efficiency fund in Ukraine and the corresponding funds in other countries, is considered. The operation of the Energy Efficiency Fund is necessary for the provision of tax benefits, subsidies (targeted state and others), irrevocable appropriations for various types of energy conservation works, for the introduction of new types of energy saving equipment and technologies.

Previous chapters in this book focus on the production of energy from different sources and how we might increase the supply to meet the anticipated growth in demand. In this chapter we focus on options to manage the energy demand. There are many ways—other than complete avoidance of the use of goods or services that demand energy—by which we can “save” energy; actually, we are not saving but reducing the growth in the demand of energy. It is often convenient to think of savings arising from two categories: energy efficiency and energy conservation. Energy efficiency reduces the energy necessary to perform a desired task, and energy conservation includes all actions that avoid unnecessary use of energy. To use the automobile as an example, development of techniques that reduce the fuel needed to go from one place to another is an example of improved energy efficiency. Substituting the automobile with a more efficient mode of transportation or the avoidance of the activity entirely would be examples of energy conservation. Thoughtful use of both conservation and efficiency will be necessary if we are to achieve substantial reductions in our future energy use as individuals, nations, or the world as a whole. As discussed in chapter 4, the global energy use projected for 2050 under three scenarios with three differing growth rates ranges from a high of 9.4 CMO/yr to a low of 3.9 CMO/yr. Our recent energy use of approximately 3 CMO/yr (since 2000) is on a growth curve that follows the trajectory of the high-consumption scenario. Improvements in energy efficiency have of course been made steadily over the past century and will likely continue in the future. Much of that improvement has already been taken into account in arriving at the projections for future growth. The 2.6% annual growth in energy consumption has taken place notwithstanding steady improvements in efficiency. To bring the projected 2050 consumption down from more than 9 CMO, we will need savings that would not happen without a rededicated effort.

Rising power costs and constraints are driving a growing focus on the energy efficiency of high performance computing systems. The unique characteristics of a particular system and workload and their effect on performance and energy efficiency are typically difficult for application users to assess and to control. Settings for optimum performance and energy efficiency can also diverge, so we need to identify trade-off options that guide a suitable balance between energy use and performance. We present statistical and machine learning models that only require a small number of runs to make accurate Pareto-optimal trade-off predictions using parameters that users can control. We study model training and validation using several parallel kernels and more complex workloads, including Algebraic Multigrid (AMG), Large-scale Atomic Molecular Massively Parallel Simulator, and Livermore Unstructured Lagrangian Explicit Shock Hydrodynamics. We demonstrate that we can train the models using as few as 12 runs, with prediction error of less than 10%. Our AMG results identify trade-off options that provide up to 45% improvement in energy efficiency for around 10% performance loss. We reduce the sample measurement time required for AMG by 90%, from 13 h to 74 min.

AbstractSustainable development of container terminals is based on energy efficiency and reduction in CO2 emissions. This study estimated the energy consumption and CO2 emissions in container terminals according to their layouts. Energy consumption was calculated based on utility data as well as fuel and electricity consumptions for each container-handling equipment in the container terminal. CO2 emissions were estimated using movement modality based on the number of movements of and distance travelled by each container-handling equipment. A case study involving two types of container terminal layouts i.e. parallel and perpendicular layouts, was conducted. The contributions of each container-handling equipment to the energy consumption and CO2 emissions were estimated and evaluated using statistical analysis. The results of the case study indicated that on the CO2 emissions in parallel and perpendicular layouts were relatively similar (within the range of 16–19 kg/TEUs). These results indicate that both parallel and perpendicular layouts are suitable for future ports based on sustainable development. The results can also be used for future planning of operating patterns and layout selection in container terminals.

In our paper we aim at analysing the social factors influencing energy use and energy efficiency in four different European countries, using the data from the PENNY research (Psychological social and financial barriers to energy efficiency—Horizon 2020). As a part of the project, a survey was conducted in four European countries (Italy, The Netherlands, Switzerland and Hungary) to compare environmental self-identity, values and attitudes toward the energy use of European citizens. Previous research has examined the effect of a number of factors that influence individuals’ energy efficiency, and attitudes to energy use. The novelty of our paper that presents four attitudes regarding energy use and environmental consciousness and compares them across four different regions of Europe. It analyses the differences between the four attitudes among the examined countries and tries to understand the factors explaining the differences using linear regression models of the most important socio-demographic variables. Finally, we present a typology of energy use attitudes: four groups, the members of which are basically characterised by essentially different attitudes regarding energy use. A better understanding of the diversity of energy use may assist in making more accurate policy decisions.

This paper analyzes the characteristics and composition of the energy consumption system of the building from the perspective of systematic energy conservation and presents the systematic framework of the consumption model. Based on the framework, the paper focuses on how to establish a building energy consumption assessment system, find the energy efficiency index system and assessment approaches, and apply the results directly into building energy conservation and emission reduction. It not only facilitates greatly the overall and efficient management of the energy consumption system of the building, but also serves as another new approach to achieve energy conservation and emission reduction.

Abstract The Swedish National Research programme for Energy Efficiency in historic buildings was initiated in 2006 by the Swedish Energy Agency. This article gives an overview of the programme: objectives, projects and the general results of the programme. The research programme aims to develop knowledge, methods and technical solutions that contribute to energy efficiency in historically valuable buildings without destroying or damaging the historical value of the buildings, including decoration, furnishings, interiors or equipment. The programme is not limited to listed and monumental buildings but covers a wider range of historic buildings that account for a large part of the energy use in the building sector. For one and two-family houses, around 25 % of the energy use is associated with buildings built before 1945. The same number for multifamily houses is around 15 %. The programme is currently in its third consecutive four-year-stage. Previous four-year-stages were completed in 2010 and 2014. Over time, the scope of the programme and the projects have developed from mainly dealing with indoor climate control in monumental buildings towards addressing more general issues in the much larger stock of non-listed buildings. Technical research, based on quantitative analysis, dominate throughout all three stages, however most projects have had interdisciplinary components. The results from the programme have been presented in 31 journal papers, 67 conference papers, five books and five PhD theses. The projects have also contributed to CEN standards and resulted in a number of Bachelors and Master’s theses. An equally important long-term effect of the programme is that the number of Swedish researchers in the field have increased from practically none in 2007 to 18 senior researchers and twelve PhD students from ten universities in 2014. The research programme on Energy Efficiency in historic buildings is unique in an international context. Hopefully it can serve as an example for other countries on how to address an important interdisciplinary research challenge.
