Abstract: t has to face the fact that raw material cost is rising and the adhesive contain formadehyde in the furniture industry. Therefore, taking corrugated Chair as a breakthrough perspective was presented in order to meet 100% recyclable demand. With low carbon theory, design strategy was proposed based on analysis of the material and user requirements. Design location: the young people.The proposed design key point contains: fewer components and easy to assemble. Abstraction and simplification, single design and community combination, simulation of irregular things, dimension transuding, four design rules as important laws in industrial design were applied to explore reasonable morphology and structure.It put forward to appraise the design schemes from six aspects: attractive appearances, assembly processing, saving in material, proper ergonomic, and poly-functionality, fully collapsible for easy storage. According to stress test, experimental results show that the schemes are feasible and valid.

Abstract: Based on the structure feature and energy consumption situation of high-rise reinforced concrete residential buildings which built in end of last century, it discussed the main energy-saving renovation technologies and methods. Demonstrating high-rise reinforced concrete residential building of Taiyuan as a case, it analyzed its heat loss problems and defects of original design. Energy-saving renovation plan proposed and put reconstruction technologies of building envelope and heating system in practice. It discusses energy-saving renovation effects, energy efficiency. Indoor thermal environment improved significantly after energy-saving renovation on building envelope and heat system.

Abstract: A series of questionnaire survey on condition of winter heating of residential building and field measure of typical cases were launched in Hangzhou. The characteristics of winter energy utilization in Hangzhou were found out through analyzed the survey data. In addition to air conditioning ,other heating devices are also important in Hangzhou which is a typical city in hot summer and cold winter zone. Moreover, as high as 98% dwelling houses have air-conditions, but in the winter, the number of dwelling house did not open air-conditioning account for about 1/3~1/2. Combined with the analysis of the measured data of typical cases can concluded that winter air conditioning use rate and time length per day are not high. It also shows that, in the hot summer and cold winter area, air conditioning is more important for summer cooling.

Abstract: The envelop enclosure reconstructuring, the natural lighting and ventilation organization, renewable resources utilization and the automatic controlling system application are four aspects that should be kept with attention in the low energy consumption reconstruction of old industrial buildings. By taking technical measures such as changing wall body, doors and windows material, rationally using wind and thermal pressure at the site, taking full advantage of energy like solar and geothermal power and introducing high-tech controlling system, the energy consumption of old industrial buildings can be effectively reduced.

Abstract: This paper presents a multi-level energy consumption model including element model, device model, building model, organization model and region model, builds the visualized energy consumption monitoring platform, combines with WebGIS and Flash allowing a variety of user operations through map-display module, system-function module and database-support module. Corresponding present a multi-level energy consumption acquisition program based on the Mesh framework of ZigBee. Compared with the traditional energy consumption monitoring software, this system gives a better user interaction and friendliness.

Abstract: Excess air coefficient has an important impact on the combustion conditions of boiler and thermal efficiency, analysis shows that the furnace temperature and the combustion efficiency is the linear relation of one to one correspondence. Any combustion conditions, there is an optimum excess air coefficient makes the top of furnace temperature, thus it can establish a control relationship, furnace temperature is optimization index, excess air coefficient is disturbance.It can achieve the purpose of improving the efficiency of boiler combustion.

Abstract: Building energy consumption is a large proportion in energy consumption. In order to improve the building energy saving behavior, the building energy consumption prediction should be adopted in practice. Using the expert system to forecast and analyze energy consumption of a steel residential building in the north region, in which the factors: the power saving for buildings and the park electric equipment, heating system control, reclaimed water and solar energy are considered. The network monitoring system is established to realize monitoring energy consumption of buildings and parks. In this case, expert system network monitoring platform can provide managers with energy saving decision-making and environmental parameters and personnel information. Finally, the optimal control for equipments is realized by use of monitoring data.

Abstract: Through the investigations on a total of 2,079 residential buildings in Shijiazhuang, the author got the distributions, ages, structures, heating and cooling patterns, indoor comfort conditions, state of energy efficiency and actual energy consumptions etc. In addition, non-energy-efficient buildings, energy-saving 30%, energy-saving 50% and energy-saving 65% accounted for 24.8%, 17.8%, 22.4% and 35.0% respectively. The author calculated the total energy consumption of 397 sample existing residential buildings which is equivalent to about 48,600 t Standard Coal, and average energy consumption per unit area was about 28.0 kg/m². The results may contribute to the future work of energy efficiency renovation of existing residential buildings in Shijiazhuang, even the whole Hebei Province.

Abstract: The research tool is self-designed “questionnaire on attitude toward energy saving and carbon reduction”. There were 1,665 subjects, with a total of 1,557 valid questionnaires. According to research findings, university students’ overall attitude is positive. Besides, environmental activities and volunteer participation experience have significant difference on overall attitude of energy saving and carbon reduction is significant. In addition, different genders and colleges of study have significant difference on overall attitude.

Abstract: To discuss the technical and economic problems that emerges in building energy efficiency reform of existing residential building in Wuhan, the energy comsumption of typical existing buildings is calculated using the Dest-h energy consumption simulation software before and after energy conservation transformation. The energy saving potential of exterior window transformation is analyzed and the economy of multiple solutions on the grounds of the market cost is discussed. Finally, taking both energy conservation efficiency and economy into consideration, the optimal and supplementary scheme of exterior window retrofitting for residential buildings in Wuhan is obtained.
