Improving energy efficiency and reducing CO2 emissions are becoming very essential worldwide. To encourage the development and application of energy-efficient and low-emission technologies and to increase people's awareness of energy-saving, many energy labelling systems are developed and utilized in most countries. Since energy labelling systems have a significant impact, more and more sectors are developing their energy labelling systems to have their products included. Globally, the transport sector consumes a great proportion of energy and is responsible for considerable CO2 emissions. Although rail vehicles have relatively high energy efficiency, a labelling system has not been developed in the railway sector, whereas other modes of transport have developed energy efficiency indicators or energy labelling systems. Therefore, it is necessary to develop an energy labelling system for rail vehicles to promote rail transport and develop the technology of rail vehicles. First, this paper gives a review of the existing energy labelling systems. Second, it summarizes the rail needs and rail stakeholders’ interests regarding energy efficiency and corresponding labelling. Last but not least, a proposal for an energy labelling system for rail vehicles is given.

The progressive development of the economy of the Republic of Kazakhstan is impossible without solving the issues of increasing energy efficiency and energy conservation. These issues are very relevant in the construction sector of Kazakhstan. Housing facilities, on average, consume 2-3 times more heat per square meter, than buildings in Europe. However, in Kazakhstan until now there is no methodology for determining the energy efficiency of buildings and structures that meets modern requirements. The methodology discussed in this article is harmonized with EU requirements and establishes a method for calculating the annual energy consumption of buildings for heating, hot water, ventilation and air conditioning, taking into account auxiliary energy for the operation of these systems, and is intended for use in the design of new construction, reconstruction (modernization) residential and public buildings, as well as operated buildings and structures.

Tall buildings around the world are increasing at an accelerating pace. However, this fast-pace development is not in tandem with today’s environmental considerations towards reducing high carbon emissions, mainly relating to the building sector (close to 50% of carbon dioxide (CO2) emissions). The vast scale and energy demands of tall buildings call for an in-depth study of this building typology towards improving energy efficiency. An important consideration for lowering energy demands is the configuration of the building envelope that acts as the mediator between indoor and outdoor conditions, according to the climate and microclimate of the building’s location. Current architectural practices of fully glazed curtain wall envelopes make this relationship problematic, by resulting in high-energy loads for achieving thermal comfort. Over the last few years, a step forward towards energy efficiency is the use of a double-skin façade (DSF). Its application, however, is lacking consideration of the specific climatic conditions that will essentially result in an energy efficient design. Previous research revealed that the most energy efficient DSF in the Mediterranean climate is with LowE glazing as the outside DSF layer. Further studies on DSF cavity width for a hot climate, were in favour of wider cavities, as these reduce the high cooling loads that are associated with this climate. Additionally, simulations of an office building in the Mediterranean climate, confirmed that cooling energy is also present during winter (airtight DSF), suggesting for a more active DSF envelope design throughout the year. A further study is then conducted through simulations, where the DSF design alternates between an open / closed DSF, and comparisons are made in relation to DSF width, building height above ground, outdoor environmental conditions and interior thermal comfort, for further improving the energy efficiency of tall building design.

Efficient Transport

The long-term transition towards a low-carbon transport sector is a key strategy in Europe. This includes the replacement of fossil fuels, modal shifts towards public transport as well as higher energy efficiency in the transport sector overall. While these energy savings are likely to reduce the direct greenhouse gas emissions of transport, they also require the production of new and different vehicles. This study analyses in detail whether final energy savings in the transport sector also induce savings for material resources from nature if the production of future vehicles is considered. The results for 28 member states in 2030 indicate that energy efficiency in the transport sector leads to lower carbon emissions as well as resource use savings. However, energy-efficient transport sectors can have a significant impact on the demand for metals in Europe. An additional annual demand for 28.4 Mt of metal ores was calculated from the personal transport sector in 2030 alone. The additional metal ores from semiprecious metals (e.g., copper) amount to 12.0 Mt, from precious metals (e.g., gold) to 9.1 Mt and from other metals (e.g., lithium) to 11.7 Mt, with small savings for ferrous metal ores (−4.6 Mt).

Radon Concentrations

A comparative analysis of the radon concentrations in modern multi-storey residential buildings of high energy efficiency class and buildings typical for urban areas of the twentieth century was carried out. The study was conducted in Russian cities located in various climatic zones – Ekaterinburg, Krasnodar, St. Petersburg, Salekhard, Chelyabinsk. The radon concentration in samples of buildings was measured using integrated radon radiometers based on nuclear track detectors according to a single method. The surveyed sample included 498 apartments in multi-apartment buildings. Among all the examined building types, the highest average radon concentration is observed in modern energy-efficient houses – 43 Bq/m3. In other types of buildings, the following average radon concentrations were obtained: brick 2–5 floors – 35 Bq/m3; panel 5 floors – 32 Bq/m3; panel 7–12 floors 1970-1990 years of construction – 22 Bq/m3; brick> 5 floors 1970–1980 years of construction – 20 Bq m3; panel, built since 1990 – 24 Bq/m3. The results of the study confirm the assumption that radon concentration in modern multi-storey energy-efficient houses is on average higher than in typical residential buildings of the Soviet period. The increased accumulation of radon in energy-efficient buildings is associated with a decrease in the building envelope permeability and the contribution of fresh air to the general air exchange. Despite the fact that there were no cases of exceeding hygienic standards for the indoor radon concentration in the framework of this study, the higher radon concentration in buildings of increased energy efficiency requires attention from the point of view of implementing the principle of optimization of radiation protection. In the future, extensive construction of energy-efficient buildings may increase the average and collective doses to the urban population in the Russian Federation.

Abstract With increasing numbers of vehicles on roads, India is facing the issue of large vehicular emissions. The burning of crude oil is the major issue behind these emissions. India doesn’t have enough resources to fulfill all the energy demands of vehicles and hence, imports crude oil from oil-rich countries. To tackle the issues associated with oil imports and vehicular emissions, there is a need to search for carbon-free alternate fuel that is available locally in sufficient quantity to meet India’s energy demands. The green economy is a new concept evolving and gaining attention worldwide, the concept focuses on sustainable and environmentally friendly solutions. Hydrogen is such a carbon-free fuel that can help to achieve the targets of the green economy and the best means to store energy for a long time. Hydrogen is a high energy content fuel and has about zero greenhouse gas emissions when used in fuel cells. Hydrogen is not directly available in free form, but it can be produced using electrolyzers and various other techniques. India’s continuously growing renewable power generation capacity gives the advantage to produce hydrogen from green sources like solar, and wind at the time of lower demand. The present review work focuses on the opportunities for India in green hydrogen production as the adaption of green hydrogen offers many benefits to India including energy security, and decarbonizing the transport sector.

On the basis of the proposed geoenergy approach, the energy efficiency of forestry and ecosystems of the Transnistrian Moldavian Republic in a single energy unit – joules has been studied. Relevance of the study is explained by the fact that the energy crisis in the 1970s has dramatically increased interest in the problem of energy consumption and energy saving. Despite the calls and practice of energy saving over a hundred years, the specific energy costs increased by 8-10 times. All these data indicate the need to introduce energy-efficient technologies of environmental management in all spheres of human activity. The geoenergy approach allows us to identify ways to optimize functioning of the forest ecosystems of Transnistria. The existing practice of forestry enterprises of the Republic leads to the destructive use of natural resources and the loss of oak plantations – the main forest-forming species of Transnistria. The final product of the enterprises is the volume of wood and not full restoration on a natural type of forests. The basis for the sustainable development model of the forest ecosystem of Transnistria is energy-efficient reforestation technology. Based on studies conducted in the Kalagur tract the article describes a technique for laying oak plantation by planting two-year seedlings (automated and manually) using forest environment, maternal spaces and the elements of natural regeneration associated rocks and shrubs. The use of mechanization is minimal in this reforestation technology and the use of the forest environment of the mother plantings is maximal. The energy intensity of the proposed reforestation technology is 0.004, which is several times lower than other reforestation technologies used in the country. The studies carried out in the Kalagur tract have also made it possible to assess the energy potential of forest ecosystems and the energy efficiency of forest management throughout the country. The proposed technology of optimization of forest ecosystems functioning allows not only to increase the energy potential of the forest, but also to create highly productive forests, valuable from economic and environmental points of view. In a promising energy-saving model of reforestation with minimal use of mechanization and other types of work we not only save energy (the cost of mechanization, fuel and labor), but also preserve the biodiversity of natural systems and increase the use of solar energy and precipitation.

Many researchers at different times have been engaged in drying cereals to preserve their nutritional properties, which is associated with the biochemical properties of materials. The technologies for drying grain crops have been developed and improved with the given recommendations aimed at carrying out the drying process at high temperatures (above 100 ° C). But the increased requirements for seed grains and the associated high energy costs do not allow the drying process to be carried out efficiently, since with large grain volumes this leads to a significant increase in material costs. The study of the laws of drying of seeds of cereals in view of improving the energy efficiency of the process is relevant. Energy efficiency is one of the main parameters influencing the choice of drying mode. In traditional technologies for drying seed material, it is dried at low temperatures, which does not allow to significantly intensify the process by increasing the temperature of the coolant, as this significantly reduces the quality of the material. The state of the art makes it possible to more accurately investigate and analyze the drying processes of cereal seeds with automatic processing and plotting of drying kinetics. The results of previous researchers were conducted on existing grain dryers, in which it is difficult to evaluate and give the correct recommendations for drying the seed material. This is due to the peculiarities of the drying process and the design of the grain dryer. To adequately assess the drying regimes, studies of drying seeds of cereals at low temperatures were carried out to preserve the seed properties of the material. To increase the energy efficiency of the drying process, a step-by-step descending low-temperature drying mode is proposed, which provides the required quality of seed material. All the proposed technical solutions for the introduction of energy-efficient regimes in the process of drying grain seeds were implemented in the recommendations for industrial drying in mine direct-flow grain dryers.
