Abstract In order to increase energy efficiency of AC rotating machines, one possibility is the use of Grain-Oriented steel sheets to build stator magnetic circuits in order to reduce iron losses. After presenting the general concept considering a non-segmented-shifted sheets prototype recently developed in our laboratory, a segmented structure is introduced. Experimental comparisons between these structures are performed using static machines. The main results are analysed using Finite Element modelling that leads to extract the particular physical concepts which govern these associations.

Project-based transactions (PBTs) are a market mechanism of attracting foreign investments in order to abate greenhouse gas emissions and increase energy efficiency of the country’s enterprises. The article provides a classification and analyzes advantages and drawbacks of PBTs from the point of view of a host country. The main trends and factors determining the dynamics of the PBT market are described. Given that Russia currently lags behind the leaders of the PBT market, an incorporation of a state carbon fund is put forward with an aim of channelling PBTs through it. This paper proposes a form of PBT market regulation by incorporating an option mechanism into the contract structure of a transaction. A comparison of the new form of regulation with the tools that are currently in use in Russia and other countries demonstrates its greater economic efficiency under uncertainty.

This article reviews energy consumption in the Kyrgyz Republic economy, environmental indicators and strategies to further develop the national fuel and energy system to ensure energy efficiency and energy saving. An existing situation in energy efficiency of buildings in the country is described. Secondary legislation and by-laws approved by the Government of the Kyrgyz Republic as well as several technical standards, norms, methods and guidelines approved by the order of the State Construction Agency of the Kyrgyz Republic are presented. Applying modern insulating materials are suggested as possible solutions to increase energy efficiency and energy saving. The advantages of EPS-beton in comparison with other thermal insulation materials are discussed and foreign experience of use of EPS-beton products in increasing energy efficiency of buildings is presented.
