Currently, Japan aims to reduce energy-derived CO2 emissions by 45% in FY2030 compared to FY2013 levels, while the targets are as high as 51% for the commercial sector and 66% for the residential sector.
Since buildings, once constructed, have a long lifetime use, a swift transition to net-zero buildings is a pressing issue. The low energy efficiency standards of houses and building stocks in Japan also mean that a vast number of existing buildings must be retrofitted to reduce the carbon impacts. The need to adopt a life cycle perspective and assessing embodied carbon emissions is also an urgent matter that must be considered to meet our targets. Renewable Energy Institute pursues studies on such topics.
