Abstract: In view of the 7 tons of small pure electric bus the ESP control program design, the rear wheel hub motor drive bus in-depth research, the dynamic stability of structures. The ESP control model and vehicle model, and on the basis of the hardware in the loop simulation experiment was carried out .Simulation working condition of selecting the step steering input and sine steering input two kinds. The results show that this article builds the ESP control model for the lateral stability of the electric bus was improved obviously.

Abstract: In this paper, the change of fossil energy consumption, carbon dioxide (CO₂) and pollutant emissions are calculated when petroleum based vehicles (PBVs) are taken place by EVs based upon the full-cycle energy efficiency theory with the energy efficiency measured from well to wheel.. Calculation results show that the fossil energy consumption, CO₂, monoxide (CO) and hydrocarbon (HC) emissions can be reduced with the substitution of EVs for vehicles that burn gasoline (GVs), but nitrogen oxides (NOx) and sulfur dioxide (SO₂) emissions increase. When vehicles that burn diesel (DVs) are replaced by EVs, the emissions of pollutants except SO₂ will be reduced, but the emissions of CO₂ and SO₂ will increase. Considering the proportion of coal-fired power generation to the total power generation in China, the goal of energy conservation and emission reduction cannot be perfectly achieved by the substitution of PBVs by EVs. Therefore, the proportion of clean energy generation should be increased in China and technological updating of coal-fired power plants for reducing CO₂ and pollutant emissions are necessary as well. Besides, GVs, other than DVs, should be replaced by EVs from the perspective of energy conservation and CO₂ emission.

Abstract: This paper studies the forming condition,reinforcement mechanism and failure condition of composite foundation, and summarizes the failure mode under horizontal load, at the end of the paper, based on these theory,the p-y Curve which Concerned with the reinforcement mechanism analysis and calculation of composite foundation has been studied.

Abstract: Double skin facade has been popular in China since new century. It provides challenges to deal with overheating problems in air cavity and improve energy saving effects in hot summer and cold winter climate zone in China. This paper develops a new ecological facade which includes three key elements: a ventilated double skin facade, a tillandsia usneoides plant curtain and watering. The biological characteristics especially the absorbtivity of tillandsia usneoides were analyzed via SEM scanning photographs. Bud scales and mesophyll cells of tillandsia usneoides are the main tissues to keep water. Then a method to construct an ecological double skin facade using condensation water was introduced.

Abstract: Energy efficiency must first be a good envelope, then consider saving technology from the device. From the perspective of building life-cycle perspective, the eco-design of energy-efficient throughout, so that the building has good ventilation and shade integrated structure, building envelope insulation effect good, reasonable equipment systems, these measures will be building energy efficiency has played a active role. According to these principles, the program selection, save energy, to obtain better results.

Abstract: In this study, a high level residential building, Building 1 (Block 1) of Qingheju low-rent community in Jinan, China is used as case for studying energy performance in its different flats under different conditions (levels, positions, opening directions, etc.). IES Virtual Environment (IES VE) is applied as main tool of simulating the building energy performance. The result reveals that flats at lower level, flats on the east side, flats with less area of external walls and openings can save more energy in both cooling and heating in this area.

Abstract: Today, the global environmental awareness becomes increasingly strong. To build beautiful and green energy-saving architecture turns to the construction mainstream. This paper studies several contemporary architectures, such as typical business, industrial and office buildings, and analyzes them from two aspects of efficiency and aesthetics. The design concept that energy efficiency is in the first place and aesthetic in the second place is proposed. The target is to comply with the requirements of environmental protection.

Abstract: With G-SEED (Green Standard for Energy and Environmental Design), an environment-friendly building certification system, Korea is promoting the efficient energy management in the building. In particular, apartments account for the biggest share of the G-SEED authentication results. However, there has not been enough evaluation or research on the environmental performance of buildings certified by G-SEED as well as its own institutional issues. Therefore, this study compared energy consumption and CO₂ emissions of G-SEED certified apartments and non G-SEED certified apartments to analyze the environmental performance of G-SEED certified apartments. The analysis shows that G-SEED certified apartments have better results than non G-SEED certified apartments in terms of energy consumption and CO₂ emissions.

Abstract: The heat loss through the envelope accounts for the largest portion of the energy consumption in a building. It takes up more than 40% of the total heating and cooling energy. Therefore, a high performance insulation envelope technology that is 80% more energy efficient than the existing systems should be the basis of passive house construction. This study aims to improve the detailed design for efficient application of sandwich insulation system. And finally, an optimal sandwich insulation detail was selected.

Abstract: Recently, the window-to-wall ratio in the building envelope has gradually increased. In summer, as a result, cooling load significantly increases because of a large amount of sunlight coming through the windows. And in winter, thermal comfort can decrease at night because of heat loss and cold radiation which take place through the windows which have relatively low thermal resistance. To evaluate on characteristics of cooling and heating energy consumption under the blind-integrated window system which can fundamentally block this kind of cooling and heating load, this study has measured inner & outer surface temperature of glazing, electricity consumption and heat flux after installing the general and blind-integrated window systems in the test bed. According to the inner & outer surface temperature of glazing, the blind-integrated window system was 20.4°C while the general one was 14.4°C in summer. And in winter, the blind-integrated window system was 2.1°C while the general one was 0.8°C. Under the blind-integrated window system, in other words, electricity consumption was saved by up to 26% (about 11% daily), and heat flux decreased by approximately 34%. In addition, it's been confirmed that heater electricity consumption in winter could be saved up to 17%.
