This paper introduces the present situation of existing residential building energy saving reconstruction of Anshan area, the result of the analysis is that the renovation of retaining structure is the key of the reconstruction of existing residential buildings of Anshan. Exterior wall area ratio of the total area of the building envelope accounts for quite large, so transformation of exterior wall is the key. Energy saving wall approach divided into external wall insulation and exterior insulation. Analysis of energy-saving measures by the external wall insulation, and the external wall of a residential district in Anshan city and analysis of thermal insulation and energy saving renovation case, better energy-saving effect, energy saving measures of external economy more external insulation, the region has provided the reference and basis transformation of external wall energy-saving residence building.

This paper expounds the importance of wall insulation energy-saving wall insulation materials, introduces the characteristics and process practice requirements. Bring forth the new through the old to accelerate energy-saving technical insulation wall material, plays a positive role in promoting to create a more comfortable living environment, provide the beneficial reference for the wall heat preservation and energy saving. Building energy saving is the main content of environmental protection and energy conservation, is an important part of sustainable development. Residential building energy-saving work unceasingly thorough, continuously improve the energy efficiency standards, the development of many new energy-saving technology, vigorously promote the use of residential buildings. But the current level of building energy saving, but also far lower than developed countries. So the building energy conservation is an important task of building industry. In the construction of the external retaining structure, the heat loss, the supporting structure of the external wall and a big share. Development and reform of building wall and wall energy saving technology is the main content of building energy-saving technology, the development of external insulation materials and energy-saving technology is the main way to achieve energy-saving building. Thermal insulation external wall energy saving is mainly divided into exterior insulation and exterior wall insulation two categories.

Windows energy saving design of residential buildings has increasingly got the attention of people. Through a large number of surveys and analysis of residential buildings in Chongqing and consumers personal experience, the author finds problems and deficiency, and then proposes principles of residential buildings sun shading reconstruction in Chongqing city. Taking the high-rise residential building of one university in Chongqing as reconstruction sample, selecting a specific time period, the author recalculates sun shading coefficient with and without sun shading by using Ecotect software to do simulation analysis. Finally, the reasonable reconstruction design pattern is put forward through cases. Keywords: Buildings Sun Shading, Sun Shading Reconstruction, Energy Saving

Reasonable determination of indoor ventilation rates are the main content of residential ventilation designs, and can save consumption by air conditioners. Firstly, the energy saving potential of ventilation cooling technology in Guangzhou is analyzed in this paper. The cooling load of a residential building in Guangzhou with different air exchange rates is simulated by the DeST-h after indoor heating quantity of different rooms is set. The energy saving rate is analyzed, the functional relation between energy saving rate of ventilation and air exchange rate is obtained using the linear-regression analysis method. After a comprehensive consideration of various factors, including variation of energy efficiency, room volume, air outlet size, and that the maximum air exchange rates of different rooms are fixed.

Korea relies significantly on imported fossil fuels to meet its energy needs. Moreover, about 50% of Korean residential buildings are apartment complexes. In this paper, the use of distributed generation (DG) technologies to serve the energy requirements for a typical Korean apartment complex is explored to reduce Korea’s dependence on fossil fuel and CO2 emissions. In particular, a series of sensitivity analyses is conducted using detailed simulation tools to determine the cost-effectiveness of DG systems to meet electrical and thermal loads of an apartment building in Daegu, Korea. The DG systems considered in the analysis include Photovoltaic (PV), Wind turbine, Microturbine, and Fuel Cell. The apartment complex is connected to the utility grid that with electricity typically generated using fossil fuels. It is found that a combination of the grid and Fuel Cell is the most cost effective approach to meet the electrical and thermal loads of the complex residential building with a cost of energy reduction of 12% compared to the grid only option.

The steel residential building has been widely used for its good seismic performances. In order to study the energy-saving behavior of the existing steel residential building, an on-site test on envelope structure of a typical steel building in cold region is conducted. Based on that, a simplified numerical model is established in which dynamic energy theories, solar radiations and indoor thermal disturbances are considered. The model is verified through testing data. Parameter analyses including 6 series sum up to 38 models are carried out on 6 main influential factors. The results show that improving thermal behavior of building envelope, adopting flexible sunshade schemes in different seasons, using even and simple building configuration and adopting different window-wall ratios for windows with different orientation are effective ways to decrease the energy consumption of buildings. The thermal design recommendations for steel residential buildings are also produced.
