And Function

The energy consumption and environmental impacts of a product are largely determined during concept design. It is the core for energy saving product development to integrate energy saving into product concept design process. In this paper, a framework for energy-saving product concept design based on TRIZ/function analysis is proposed, the energy flow chart is built based on the analysis of product function. By eliminating the harmful function associated with energy and environment, resolving the conflict parameter and attributes of components in energy and function, the new product that satisfy user needs while minimizing energy consumption is obtained. A case study is also presented to illustrate the effectiveness of the proposed design framework.

The aim of green innovative design is to improve environment efficient by function innovation. In order to help designer to generate new product ideas giving attention to customer needs and environment demands, a green innovative design framework based on function analysis is proposed. This framework integrates green design rules and environment factors into the process of function innovation. By analyzing and resolving the functions that will bring environment loads, the new product ideas with low environment impact and energy consumption are obtained. A case study is also presented to illustrate the effectiveness of the proposed design framework.

Interpretation Systems

The product concept is crucial in new product development (NPD) because it represents an NPD project’s goal. In this context, most prior studies have regarded product concept development as a linear process but some recent studies have revealed that it also has nonlinear characteristics. The objective of this paper is to explore why this inconsistency has arisen and to develop a model and theory that illustrate both aspects of product concept development. To achieve this, we adopt the perspective of organisational interpretation systems (Daft and Weick (1984). Toward a model of organisations as interpretation systems. Academy of Management Review, 9(2), 289–295) and explore eight product development cases. Consequently, we develop a three-stage model and find that the linearity or nonlinearity of product concept development is determined by each NPD team’s assumption about the environment. We also consider product innovativeness and function equivocality, and establish that these are related to the NPD teams’ assumptions about the environment.

Recently, environmental protection has become one of the most critical concerns on a global scale. Currently, it is widely recognized that lifecycle assessment (LCA) is a very effective instrument used to evaluate the environmental impact of various products quantitatively across their whole lifecycle. A basic LCA survey of Shinkansen vehicles and cross ties was conducted as a case study for the railway system. Through this study, the following results were confirmed. For any type of vehicle, more than 95 per cent of lifecycle energy consumption (LCE) and lifecycle CO2 emission LCCO2 is attributable to vehicle running. Lightweight vehicles, reduction of running resistance and the use of regenerative brakes contribute to energy saving in vehicle running. Regarding the CO2 emission from four types of ties (wood, concrete, synthetic and steel), wood ties emit the least amount of CO2 and synthetic ties the most. When the effect throughout the lifetime is considered, however, wood ties are by no means insignificant in terms of the environmental load. As a result of this survey, useful knowledge for applying LCA to railways was obtained.

A new model for energy-saving in cast irons production introduced technology contribution has been developed. According to the analysis model, in case of keeping same energy efficiency of device, the higher technological level increases, the easier the R increases; even if keep the same melting and heat treatment devices, significant reduction of production energy consumption would be implemented just depending on the production yield increase. A case study results show that technology measurements which has no direct effect on energy consumption play an important role in energy conservation, where the contribution rates of lost-foam casting and computer technology are 20% and 17%. The technological measurements play an important role in cast irons production which cannot be ignored.

Insulation Performance

Passivhaus EnerPHit is a rigorous retrofit energy standard for buildings, based on high thermal insulation and airtightness levels, which aims to significantly reduce building energy consumption during operation. However, extra retrofit materials are required to achieve this standard, which raises a contradiction between how to balance the environmental impacts of the retrofitting material inputs and extremely low energy consumption after retrofit. This motivated the analysis in this paper, which aimed to evaluate the possibilities of reducing the required retrofitting material inputs when trying to achieve the EnerPHit energy standard using a typical suburban dwelling in China’s hot summer–cold winter climate region as a case study. Firstly, how the insulation performance of each envelope component affected the building’s energy consumption was analysed. Based on this, sensitivity simulations of combinations of different insulation levels with different fabric components were investigated under four scenarios of insulation levels, airtightness and glazing choice. The final proposed retrofitting plans achieved the EnerPHit standard with insulation materials’ savings between 18% to 58% compared to a baseline retrofit plan, and this led, in turn, to 3.9 to 12.6 tonnes of carbon reductions. Moreover, an energy-saving of 87% in heating and 70% in cooling was achieved compared with the pre-retrofit dwelling.

Pollutants Emission

Low energy efficiency, energy shortage and energy related environmental issues are the important limiting factors for the development of China. As a developed province, high economic growth has had huge implications for great energy consumption and produced significant air pollutants in Shandong. REPI model is introduced to analyze the evolution of the performance of energy consumption, emissions of SO2, soot and industrial dust in Shandong over the past 12 years. Energy saving index of Shandong kept going up since 1997 and surpassed 1 in 2002, which means the obvious decrease of energy efficiency. SO2 saving index was greater than 1 in 1997-2002 then less than 1 in 2003-2008, which shows SO2 control in Shandong is significant. The saving index of soot and industrial dust kept much less than 1, which means the reduction of these two air pollutants are much better than China average level in the study period. Though the saving indexes of SO2, soot and industrial dust are all less than 1 after 2002, which show the reduction of these pollutants are above China average level, we should still be aware for the massive emissions of these pollutants. To balance economic development, energy saving as well as pollutants reduction, Shandong is faced with huge pressure.

Phase change building materials are a category of building materials with the integration of structure and function, which can be achieved by phase change materials composite with the traditional building materials. They have such characteristics as the improvement of energy saving efficiency in buildings, the decrease of heating energy consumption and the adjustment of thermal comfort in the room environment etc. Therefore, phase change building materials are one of the most efficient means of energy utilizations, which has important significance for promoting their investigation and applications of energy saving in buildings.
