Research paper (scientific journal), Joint Work, Accepted, ISSN 1348-0685

The study examined the effects of the thermal environment in a terraced classroom on students' psychological sensations and concentration. The classroom thermal environment was continuously measured during 90-min lectures in May 2013. Students were asked to complete a questionnaire on their psychological sensations and concentration every 15 min during the lectures. Objective measurement data and subjective questionnaire data were analyzed. Results show that spatiotemporal heterogeneity of the classroom thermal environment was likely an important factor in students' psychological sensations and concentration.

Previous studies have revealed relationships between specific residential environmental factors and residents' health status. However, no previous study has considered the comprehensive health risk due to overall residential environment. Therefore, a large-scale nationwide questionnaire survey was conducted using CASBEE Health Checklist to examine the residential environment of detached houses and residents' health status. Results show that overall residential environment was likely an important determinant of health and was associated with disease prevalence among residents.

CASBEE-City, a comprehensive environmental assessment tool for municipalities (cities, towns, and villages), was developed to support citizens, local governments, and other stakeholders in understanding their local conditions. In this study, the aim was to examine the tool's practical effectiveness through a nationwide questionnaire survey. The statistical relationship was analyzed between the subjective assessment results (citizens' satisfaction with local conditions) and the objective CASBEE-City assessment results, which are based on public statistical information. A clear relationship was found between the subjective and objective assessment results for municipalities, thus verifying the tool's effectiveness.

A time-series assessment of urban environment was carried out by using “CASBEE-City” tool in Kobe city to visualize the disaster recovery process. As a result of the assessment, it was revealed that the score for quality of Kobe city calculated by the tool got drastically worse soon after the Great Hanshin-Awaji Earthquake in 1995. However, the score for quality of Kobe city has gradually recovered after the earthquake and has improved to the current position along with the progress of the reconstruction.

Research paper (scientific journal), Joint Work, Lead author, Accepted, ISSN 1341-9463

Environmental performance assessment tool for municipalities (CASBEE-City) has been developed and upgraded since 2008. The tool automatically queries the database and extracts the necessary data for conducting the nationwide municipality assessment. The tool also incorporates GIS functionality and enables tool users to understand the conditions, strengths, and weaknesses of their municipalities in comparison with other municipalities in Japan by visualizing the assessment results on easy-to-understand maps.

DEVELOPMENT OF A SUGGESTION TOOL FOR ENERGY-SAVING ACTIONS BASED ON THE ANALYSIS OF RESIDENTS’ BEHAVIORS AND ENERGY CONSUMPTION

富越大介 , 伊香賀俊治 , 川久保俊 , 藤崎浩太

日本建築学会技術報告集 (日本建築学会) 19 ( 42 ) 655 - 660 2013.06

Research paper (scientific journal), Joint Work, Accepted, ISSN 1341-9463

It is important to promote energy-saving actions toward the reduction of CO2 emissions in residential sector. Residents should understand the actual conditions of energy consumption in their home in order to make energy-saving actions more effective. Therefore, in this research, a tool which suggests effective energy-saving actions was developed based on literature research and questionnaire survey. A workshop was conducted in Kawasaki City. Then, the residents received the information of their actual energy usage and effective energy-saving actions suggested by the aforementioned tool. As a result, 6.4% of CO2 reduction was achieved.

ENVIRONMENTAL PERFORMANCE ASSESSMENT OF MUNICIPALITIES WITH THE “CASBEE-CITY” TOOL

川久保俊 , 伊香賀俊治 , 村上周三 , 浅見泰司

日本建築学会環境系論文集 (日本建築学会) 78 ( 683 ) 63 - 72 2013.01

A comprehensive, nationwide assessment of whole municipalities in Japan was conducted using the Comprehensive Assessment System for Built Environment Efficiency (CASBEE) tool specifically designed for city level assessment (CASBEE-City). As with other tools in the CASBEE family, CASBEE-City is also based on the concept of environmental efficiency and calculates the value for built environment efficiency (BEE). In this study, BEE is calculated by using public statistical information and visually displayed on a map through a geographic information system (GIS) to understand the current situation of all municipalities in Japan under the same assessment criteria (same assessment items, thresholds and rating functions).
