Abstract: Extensive public participation activities conducive to the smooth commencement of building energy efficiency, public participation and awareness building energy will determine the strength of the effect of the implementation of building energy efficiency. Therefore, this paper is based on empirical investigation of Xi'an, the use of factor analysis to explore the underlying causes of the impact of public participation in the construction of energy-saving consciousness.

Abstract: As a new method of obtaining information and disposal pattern, wireless sensor network has been a hot issue nowadays. In this paper the network model and energy consumption model of wireless sensor network are introduced firstly. The improved inspiring factor takes energy into account. Then a parallel ant colony algorithm based on award-punishment mechanism is proposed. The experimental results show that the energy consumption and time delay of the improved algorithm are superior to energy efficient ant based routing and basic ant colony algorithm.

Abstract: Nowadays, due to the huge energy consumption, the energy-saving problems of the product have been emphasized with many designers. In this paper, informed by the modular design method, the total energy performance in modular product can be analyzed and separated into the energy performances of basic modules. And with the physical analysis of basic modules, the energy equations are established with the band graphs theory. Then, the physical parameters, which could influence the energy consumption, are identified as “energy factor”. Thus, the energy consumption of the modules could be optimized with adjusting design factors, and the energy-saving design scheme for the whole product is obtained in the optimized model. Finally, the model and the method in this paper are demonstrated by an instance of the crank block pump.

Abstract: This paper deals with the energy-saving product design involving the product energy property into design process. On the basis of the energy factors concepts, the paper analyzes the extraction process and energy effectiveness model of energy factors. To study the air-conditioning refrigeration system, the paper establishes the energy information model, recognizes the crucial and controllable energy element and extracts the energy factor set C = {compressor volumetric efficiency λ, motor efficiency ηd, power frequency fd, heat transfer performance coefficient φ, finned lateral general area Ao}. Then it makes a further decomposition of coupling energy factors λ, φ and finds out the corresponding design parameter. In the end, the paper maps the energy factors and design parameter into design process, establishes the energy effectiveness model and presents several measurers for decreasing the energy consumption during the actual use of air-conditioner.

Abstract: Experiments for a new type of electric discharge machining (EDM) were conducted with the water film dielectric formed by tap water and compressed air. An energy factor E is introduced and employed to estimate unit-area effective power input. The experiments show that the flushing conditions with lower air jet pressure can get lower relative tool wear and higher material removal rate (MRR). Higher discharge current and higher energy factor E obtain the higher MRR in air-aided water EDM with positive polarity tool.
