Embodied Energy and CO2 Associated with Buildings by Using Input and Output Table in Japan

In July 2009, the 2005 basic Japanese input/output table was publicized together with its physical transaction table. This research paper analyzed the 2005 IO （input/output） table to create building industry-related intensities and, at the same time, compared the building industry with industries at large for distribution margins and transportation. The analysis of distribution margins separately for middle and purchaser margins found that middle margins in the building industry are minor at 35% of the averages for all industries, while purchaser margins are sizable at 1.8 times, proving that it is an industry for which local production for local consumption is quite effective. CO2 emissions resulting from transportation in the building industry were calculated and concisely characterized. Although the ratio of transportation CO2 emissions to total CO2 emissions in each industry finds almost no difference between general industries and the building industry, transportation CO2 emissions per production value are two to three times heavier than those from general industries to be justified as a transportation-intensive industry.

以数字建筑破困局立新势

施工企业最核心的是一个一个的项目,项目的数据是企业最核心的数据。解决项目的数字化,保证数据是丰富的,真实的,是企业数字化转型的关键。近年来国家一直在倡导产业转型升级、推动高质量发展。在全行业大河奔流般的转型浪潮里,建筑业已经不能继续安于一隅。那么,为什么建筑业也亟待转型升级呢?这要从建筑业的整体环境说起。
