Currently, energy-saving building is a hot topic in society, which is also generally recognized as the most direct and effective way with the greatest potential for energy saving in the industry when the energy problem has become increasingly urgent today. At present, the domestic scholars less focus on rural residential energy saving, so the energy efficiency assessment on countryside buildings is still a relatively new field. This paper introduced existing energy-saving building assessment system at home and abroad through referring to the domestic and overseas existing assessment system, combining the characteristics of energy efficiency of rural residential buildings in China, constructed the energy-saving evaluation index system of rural residential buildings. Expert opinions and analytic hierarchy process (AHP) were used to determine the index weight, and the rationality of the evaluation system was determined by an empirical analysis case.

In China, the transformation of existing buildings is confronted with various problems in aspects ranging from technology to policy and even to economic efficiency, which restrains the pace of existing building transformation. Aiming at these conditions, a building model is established with simulation software in the research herein to deeply analyze the energy-saving effect of building envelope transformation in different climatic regions and its economic efficiency based on regional and national policies. The research results show that any single technology is difficult to completely satisfy the requirements of current energy efficiency standards, and technical measures should be taken according to different climatic regions. For the northern heating area, the building envelope transformation must be carried out simultaneously with the transformation of heat metering. Policy formulation and fund determination for the energy-saving transformation of existing buildings in China should be more flexible based on transformation effect and rely more on social and commercial forces rather than solely on the promotion of government.

Abstract In this article the research is concentrated on defining the possibility and potentials of design to enhance the energy efficiency and refine the climate conditions in the existing residential buildings in Armenia. The digital model of existing residential building is used to calculate the annual energy consumption, by simulation software—Autodesk Green Building Student. The horizontal solar panel systems offered by local market leaders were applied to calculate the annual savings, the required installation area, prices, etc. Consequently, the actual efficiency of energy saving technological process of residential buildings in Armenia is estimated. Based on the applied strategies and obtained fact, some recommendations are made for residential buildings. This article is intended to help and to be stimulus for architects and constructors to consider and include green technologies in their new projects.

There were presented the findings of the research in energy saving and energy efficiency of public and residential buildings with the purpose of evaluating the energy saving potential on the basis of energy audit. There was demonstrated the nature of energy consumption and the evaluation figures of energy saving in state-financed sphere and housing sector of the country. On the basis of research and calculations of various specialists it was determined, that the highest potential of energy efficiency improvement belongs to the housing funds of the country. It was pointed out that capital repairs and reconstruction of the existing housing funds are the necessary condition of implementing the energy saving measures. The investment issues, their types and their attractiveness for energy saving measures and improving the energy efficiency are reflected.

Energy Efficiency Improvement

AbstractDirective (EU) 2018/2002 of the European Parliament and of the Council amending Directive 2012/27/EU on energy efficiency sets a target of 32.5 % energy efficiency to be achieved by 2030, with a possible upward revision in 2023. The directive also stipulates that the obligation to achieve annual energy savings must continue to be met after 2020. In addition, a revised directive on the energy performance of buildings was adopted in May 2018. It includes measures to speed up the renovation of buildings and the transition to more energy-efficient systems, as well as to improve the energy efficiency of new buildings, thus using smart energy management systems [1].Buildings consume the most energy and have the greatest energy saving potential. They are therefore crucial to achieving the European Union’s energy saving targets. The EU allocated around 14 billion EUR to improve the energy efficiency of buildings in the period of 2014–2020, of which 4.6 billion EUR was intended for residential buildings. In addition, the Member States have earmarked 5.4 billion EUR of public co-financing for the improvement of all types of buildings, of which around 2 billion EUR is allocated to residential buildings.Multi-apartment residential buildings in Latvia are in a technically unsatisfactory condition. In Latvia, the service life of multi-apartment residential buildings has been artificially extended. In addition, there is also the problem of reduced construction quality. Housing problems affect all layers of society, but they are most acute for low- and middle-income people.The aim of the research is to study, using the co-financing of the European Union Structural Funds, the activities performed during the renovation process of multi-apartment residential buildings in Latvia and to identify the shortcomings.
