Electricity is becoming increasingly important in our modern life, particularly in developed countries and recent generations. This contemporary energy allows smart programming and more refined uses. As a result, there is a need for better energy efficiency of Electrical and Electronic Equipment (EEE). In this context, the design of EEE must meet statutory obligations in order to reduce their consumption of primary energy by considering equipment over their whole life cycle. European legislation (WEEE, RoHS, ErP, REACh) has played a major role in deep technological change and has placed the environment at the center of the sector's interests. This article presents some of the many recent developments in normative and legislative matters.

Over the last hundred years the booming exhibition industry has promoted development, which in turn has led to environmental damage. The construction of exhibition buildings has been part of this phenomenon. At first sight improvement in energy efficiency techniques would seem to offset the increased energy demand from both exhibitions and exhibition buildings. However, whether energy efficiency technologies truly help to improve building performance to the point where a building is ‘environmentally friendly’ throughout its whole life-cycle is uncertain. This research is part of investigating whether energy efficiency technologies are really the easiest means to lower costs and energy requirements when the whole useful life of an exhibition building is considered. This article investigates the energy use of three case study buildings based on their operating and embodied energy flows. The results suggest that modern technologies for making exhibition buildings more sustainable may not be as effective as the simpler strategies used over 100 years ago. This suggests a different approach may be needed for sustainable development in the twenty first century.

Abstract Nowadays, in the field of civil engineering there exists an upward trend towards environmental sustainability. It relates mainly to the achievement of energy efficiency and also to the emission reduction throughout the whole life cycle of the building, i.e. in the course of its implementation, use and liquidation. These requirements are fulfilled, to a large extent, by green buildings. The characteristic feature of green buildings are primarily highly-sophisticated technical and technological equipments which are installed therein. The sophisticated systems of technological equipments need also the sophisticated management. From this point of view the facility management has all prerequisites to meet this requirement. The paper is aimed to define the facility management as an effective method which enables the optimization of the management of supporting activities by creating conditions for the optimum operation of green buildings viewed from the aspect of the environmental conditions

Based on a systemic analysis of the factors which might influence building energy efficiency, a cluster of corresponding indicators are proposed and screened for different stages in the whole life-cycle of buildings. A questionnaire survey was conducted to confirm the weights of the selected indicators and identify critical control objects for building energy saving. This research provides the methodology for selecting appropriate control objects for building energy-efficiency under various management scenarios.

Saving energy is one of the basic national policies, and energy efficiency in building is the important part of energy conservation work. It is of great significance to develop this work permanently. Discusses the definition of energy efficiency in building, introduces the concept of the life cycle, and sets up the life cycle cost estimation model. Through the analysis of energy saving building, comes to an important conclusion. Although the initial investment of energy saving building increases, the whole life cycle cost is obviously lower than general building. With the increasing of the discount rate and the extension of life cycle, the effect is more outstanding.

Objective To study and analyze the life-cycle carbon emissions of existing rural residential energy retrofit projects to provide theoretical and data support for local rural green development and sustainable construction. Methods Life cycle analysis (LCA) was used to analyze and compare the life cycle carbon emissions (LCE) of a rural residential envelope energy efficiency retrofitting project in central Gansu. Results It was found that rural dwellings have a very high potential for energy efficiency retrofitting, and the contribution of retrofitted homes to CO2 emissions reduction can reach more than 30% over the whole life cycle. Secondly, during the retrofitting process, neglected in previous studies, carbon emissions account for about a quarter of the LCE. It is concluded that introducing LCA into evaluating rural residential energy retrofit projects' energy-saving and emission reduction benefits is more scientific, reasonable, and necessary.
