Building Energy Conservation, especially the research about residential building energy in face of the worldwide energy crisis is particularly urgent. At present, various countries have an in-depth study of the residential building energy to explore different methods, new building materials, and new technology(such as new thermal windows and doors), as well as the use of new energy has been put more attention to in energy conservation field. Comparing the residential buildings between domestic and overseas countries’ progress about related technologies, we could find some evolution and look to the prospects for the future in energy-saving field. We took a domestic project that used energy-saving technology as a practical example, and then made a simple overview of the current energy situation in China so as to get a glimpse of the development about residential building energy-saving. Finally, the article provided some comments about this topic in sustainable view.

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.

The building energy consumption simulation software DeST is used to analyze the effects of fixed shading over external window on energy consumption and efficiency, on the base of a residential building in Shanghai. The simulation results show that the fixed shading over south window has little effect on the overall energy saving of residential building. For east and west external window, if window area is not very large and its shading performance is better, the effect of fixed shading installation on energy saving is not obvious. On the contrary, if its area is large and its shading performance is ordinary, the effect is remarkable. Furthermore, when room ventilation capacity is poor, the effect of energy saving by fixed shading installation is more prominent.

In China, a surging urbanization highlights the significance of building energy conservation. However, most building energy-saving schemes are designed solely in compliance with prescriptive codes and lack consideration of the local situations, resulting in an unsatisfactory effect and a waste of funds. Moreover, the actual effect of the design has yet to be thoroughly verified through field tests. In this study, a method of modifying conventional building energy-saving design based on research into the local climate and residents’ living habits was proposed, and residential buildings in Panzhihua, China were selected for trial. Further, the modification scheme was implemented in an actual project with its effect verified by field tests. Research grasps the precise climate features of Panzhihua, which was previously not provided, and concludes that Panzhihua is a hot summer and warm winter zone. Accordingly, the original internal insulation was canceled, and the shading performance of the windows was strengthened instead. Test results suggest that the consequent change of SET* does not exceed 0.5 °C, whereas variations in the energy consumption depend on the room orientation. For rooms receiving less solar radiation, the average energy consumption increased by approximately 20%, whereas for rooms with a severe western exposure, the average energy consumption decreased by approximately 11%. On the other hand, the cost savings of removing the insulation layer are estimated at 177 million RMB (1 USD ≈ 6.5 RMB) per year. In conclusion, the research-based modification method proposed in this study can be an effective tool for improving building energy efficiency adapted to local conditions.
