Research On Theory And Method Of Green Design For Energy Saving

With the increasing economy people have to face the more and more serious problems of environment and resource. In the past decades, people have done a lot of work, such as pollution treatment and clean production, and made some achievements. However these terminal-type methods cannot solve the environment problems ultimately because the basic properties have been determined in the design phase and will produce all kinds of environmental effects in the product life cycle. Many people have realized that Green Design is a key to the environmental problems in manufacturing. In most studies of Green Design have been emphasized with attention being given to the Energy-Saving Design which has the Energy-Saving Property, also embodies the affected environment and the affected cost by the Green Property and the Economy Property.Informed by the recent research, with the Design Method and the System Approach, FBAS design framework is proposed. Analyzing products energy consumption in the life cycle, this article aims at creating Utility Model which could validly describes the consumption of energy in the products and detecting the relationship among the Energy-Property, the design process and the design information. This study further establishes a green design model for energy saving on the base of two presented concepts called "Energy-Design Factor" and "Design Union".The extraction of the Energy-Design Factor is established. First, the "Energy Aspect" and the "Important Energy Aspect" are defined after analyzing the Product Energy-Flow system. The Energy Factor Utility Model map is established, which separates the extracting process of the Energy Factor into three courses (identification, extraction and application). Second, the product information is classified, which is the base of the Energy Aspect identification. Third, the identified Energy Aspect principles are formulated and the Energy Aspect tridimensional-identifying model is given. Fourth, the mechanism and the decision principles for extracting the Important Energy Aspect are created and the quantized-analysis process for Energy Aspect is given. The relation between the represent of Energy Factor and the Design Union is expounded in the end.Life cyclic energy consumption model is proposed, which is base of the extraction of the Energy Factor. With recent study of consumption of energy, the analysis of the energy consumption is extended to the whole life cyclic, and the energy-function in the serial state variation is defined. The product energy consumption in the each life cyclic phase is expounded and the corresponding quantized energy formulas are established. Then the top Energy Factors in each step of the whole life cyclic are obtained.The represents of the Energy Factor is marked two parts: single-aspect and multiple-aspect. Aim at the inflexion of the life cyclic (single-aspect), the affecting factors of the energy inflexion is...
