Abstract: In order to expand sustainable homes into the housing market, effective methods or systems for promoting sustainable housing design need to be widely disseminated in the society. In Japan, there are three important public systems related to sustainable housing design, namely the Housing Performance Indication System (HPIS), long-life quality housing (LQH) certification, and Comprehensive Assessment System for Built Environment Efficiency (CASBEE) for detached houses. The HPIS has stipulated the housing performance indication standards over 10 categories. The LQH system certifies houses that meet the criteria of long-life quality housing. CASBEE for detached houses comprehensively assesses and rates the sustainability of detached houses. However, there still remains room for further improvement in the set of these existing Japanese systems. First, the application of the systems to existing homes has been extremely limited until now. Second, CASBEE for detached houses, the one and only national comprehensive system, has not been used so often thus far. Moreover, readiness of the systems for emergent challenges, namely climate change and aging population, has also been insufficient.
