It is necessary to consider measures to promote well insulated houses toward the reduction of CO2 emissions in residential sector. However, it is difficult to determine effective measures since residents’ attitude toward introducing insulation differ from one by one. Therefore, in this study, a model for predicting the diffusion process of well insulated house was developed taking residents’ attitude toward introducing insulation into account. The model enables us to consider effective measures for promoting well insulated house. As a result of case study, presenting energy benefits and non-energy benefits was more effective than giving economic incentive in the study.

1. This study has carried out a cost benefits analysis for each stakeholder in an attempt to develop low-carbon communities and cities by implementing regional cogeneration systems and leasing photovoltaic systems to commercial buildings.
2. As a result, the economic benefits for energy service provider acting as an investor have been proved when non-energy benefits (NEBs) are accounted. In addition, numerous benefits to stakeholders other than investor have been proved. Also, subsidies by public sector (National, Local Government) or tax incentive program will increase the economic efficiency for energy service provider (investor).
3. Since building owners and building users will gain NEBs such as of increase in real estate value, risk reduction (contribution of business and living continuity plan (BLCP), regulatory compliance etc) and maintenance cost reduction, possibility for redistribution of NEBs to the energy service provider (investor) in the form of service charge (rent, energy expense etc) have also been considered.

In the past two decades, CO2 emissions in Taiwan have sharply increased, but models for forecasting the future trend are still insufficient. In this study, based on the energy consumption of residential sector from 1990 to 2010, CO2 emissions were estimated up to 2050 using the macro simulation method. The model presents the final energy consumption and CO2 emissions by category of fuels and final usages. Several scenarios were applied to examine the possibility of achieving the goal set by the government; the most effective result shows 27% reduction by 2020 and 64% reduction of CO2 emissions by 2050.

A questionnaire survey was administered to adult residents of three locales: a large city (Kitakyushu city); a small city (Obuse Town); and a rural village (Yusuhara town), in order to clarify the hierarchical structure of health related factors of housing and regional environment dependent on urban structure and scale. As a result of structural equation modeling, health related factors model in Yusuhara was shown that 35% of residents’ overall health may depend on their housing and regional environment, and it was the largest percentage of three locales. Besides, differences were found among the health related factors structure. These results indicate that design guidelines for health promotion that correspond to the urban structure and scale will be required.

Toward mitigation of climate change, the Japanese government targeted that greenhouse gas emissions will be reduced by 80% of the 1990 level by 2050. However, CO2 emissions in non-residential sector are rapidly increasing, making carbon reduction in this sector a crucial concern. It is essential to establish CO2 reduction target and agenda based on the analysis of energy consumption and the prediction of the CO2 reduction potential. However, a lack of statistical data of floor area makes it difficult to conduct an analysis and prediction. Therefore, database for floor area of non-residential buildings has been developed in this study. This database includes stock and flow data of floor area by building use type and area which have a major impact on energy consumption in nonresidential buildings. This database can provide valuable information for carrying out countermeasures in non-residential sector.

Cities must improve their quality without an increase, or ideally with a decrease, in the amount of environmental load to become more sustainable. In order to monitor city’s progress towards sustainable development goals, a Comprehensive Assessment System for Built Environment Efficiency (CASBEE) tool, named CASBEE-City has been developed. All cities in Japan are assessed from the following two aspects: environmental load (L) on the external environment and quality (Q), which represents the citizens’ quality of life inside the city. Built environment efficiency (BEE = Q/L) is then calculated for the comprehensive assessment of each city. A high BEE value indicates that the city has excellent environmental efficiency. The assessment results are visually displayed on the map by using a geographic information system so that citizens, local government officers, and all other stakeholders can easily understand the actual status of their city in comparison with other cities in the country. This assessment and the visualization of the results are expected to support the realization of future sustainable cities. © 2011 SUSB Press. All rights reserved.

In 2009, the Japanese government published their greenhouse gas (GHG) emission reduction target to reduce GHGs by 25% by 2020 and 80% by 2050. To meet this target, formulating suitable policy has become an urgent issue. In this study, we have developed a model for predicting the low-carbon technology adoption rate based on the detached homeowners' decision-making structures. In addition, we have considered policies for meeting the reduction target. This study aims to propose policies to meet the reduction target, and to contribute to the realization of a low-carbon society.

The effect of CO 2 reduction in Japanese residential sector on various future scenarios for low-carbon society was estimated by the developed forecasting model considering the difference of energy consumption structure in different family types, different geographical area and different house types. Based on the results of forecasting model simulation by 2050, needed policies to achieve the Japanese CO 2 reduction goal (25% reduction at 2020 and 80% reduction at 2050 comparing to CO 2 emission at 1990) was discussed in this study. Results of forecasting simulation showed following 2 aspects. 1. Spread of low carbon technologies (LCT) into residential sector was indispensable to achieve the CO 2 reduction goal in 2050, however, the spread speed of LCT couldn't catch up with the expected speed of CO 2 reduction to reach the goal in 2020. As an additional measure, reduction of CO 2 emission factor for electricity was indispensable. 2. Spread of LCT into existing houses was indispensable to achieve CO 2 reduction goal both in 2020 and 2050, because the CO 2 reduction was not enough to achieve those goals even if the introduction of LCT was obligated to all of new buildings.

It takes many years to recover the initial investment cost for installing housing insulation through savings from energy reduction (Energy Benefit:EB), since construction cost is very high in Japan. This long payback time is the major barrier to the promotion of well-insulated houses. However, it has been found that if Non-Energy Benefits (NEB) of well insulated houses, such as improvement in personal health, reduction of medical expenses and decline in absences from work are all taken into account, the time required to recover the initial investment cost would change from 29 to 16 years. Therefore recognition of NEB is expected to encourage residents to invest in residential thermal insulation. NEB of well-insulated houses is thus evaluated regarding human health in this study.

The purpose of this study is to analyze the health determinant factors of housing and regional environment in the suburb of Kitakyushu. A questionnaire survey was carried out among the middle-aged and elderly people in Yatsue district, the city of Kitakyushu, in order to clarify the respective influence of houses and regional environment, including the various sur-rounding environments, on residents' health. As for self-rated health, 80% of the respondents claimed, “I am in good health” or “I am not in bad health”, and there was no great distinction among age groups. The result can be shown that this district is healthy. Health related factors modeling showing the relations among housing, regional environments, and health was proposed, based on structural equation modeling. This model indicated that 23% of residents' health may be dependent on the influences of their houses and regional environments. This model also showed that residents' health had strong cor-relation to questionnaire items such as “indoor thermal environment” of houses, and “community activities”, “neighbor-ship” and “green space” for regional environments. Therefore, it is possible that residents' health may require appropriate maintenance through creation of good house and regional environment.
