Forecasting Development Directions on Environment-Friendly Building Science for Energy Saving by Analyzing Patent Trend

Abstract

The building structure has an decisive influence on the environment as it takes over one third part in the energy consumption and greenhouse gas emissions of whole world. Accordingly, every country makes the reduction of greenhouse gas emission compulsory pursuant to Kyoto Protocol of 1997, and Korea government makes an announcement for the improvement of building energy performance in 2014. In this study, the key technology of Energy Saving Environmental-Friendly Building is sorted into 3rd categories, and the analysis of patent trend for patent documents published in Korea, USA, Japan and Europe is carried out. The purpose of this study is to solve the problem of current technology that it cannot show the detailed situation of technique and development strategy of R&D, and to provide a systematic approach for R&D strategy and an exact technology development direction.

Evaluation and Suggestions for Rational Energy Tax Policy in South Korea

“…However, this energy conversion policy is inferior in terms of the effectiveness because the proportion of coal-fired power generation has recently increased. That is, the externalities, such as environmental costs and the measures to reduce particulate matter, do not meet the national expectations, and a detailed implementation plan for greenhouse gas (GHG) reduction is lacking [4]. The rationalization of energy taxation as a means is strongly required for the active implementation of such energy conversion.…”
