Eco-Efficiency Evaluation Considering Environmental Stringency

This paper proposes an extended data envelopment analysis (DEA) model for deriving eco-efficiency. In order to derive eco-efficiency, the proposed model utilizes the concepts of operational efficiency and environmental efficiency. Since DEA can separately measure operational efficiency and environmental efficiency, the treatment for constructing the unified indicator is required to ultimately e...

The efficiency and eco-efficiency of manufacturing

In this paper, we review the efficiency of both manufacturing processes and systems over recent decades and compare nano-materials technologies in this context. To a first approximation, nano-materials processes appear to be about as efficient as semi-conductor processes. That is, their second law efficiencies are of the order 10, while conventional processes are of order 10. However, many of t...

WATTSBurning: Design and Evaluation of an Innovative Eco-Feedback System

This paper reports a 15 weeks study of artistic eco-feedback deployed in six houses with an innovative sensing infrastructure and visualization strategy. The paper builds on previous work that showed a significant decrease in user awareness after a short period with a relapse in consumption. In this study we aimed to investigate if new forms of feedback could overcome this issue, maintaining th...

Eco-Village and Climatic Design

Eco village design is a new field of knowledge still under development. It will be the physical manifestation of the unfolding of the ecovillage dream held by so many. It is generally agreed that concept of sustainability should play an increasing role in future urban development world-wide. In order to ensure ecological sustainability, cities around the world have to decrease their environment...
