低炭素社会への移行が求められる中、様々な温暖化対策が講じられてきたにも関わらず、民生部門だけは依然としてCO2排出量が増加の一途を辿っている。特に、排出量の伸びが顕著である民生業務部門において、更なる温暖化対策の実施が最重要課題とされている。そこで本研究では、民生業務部門のCO2排出量とその削減に要する費用を推計し、費用対効果の観点から評価する手法を開発する。本手法により、実施すべき具体的対策の内容や導入時期、規模等を検証する。

近年、建築材料における環境負荷低減方策として、再生可能な資源、環境負荷の低減に資する原材料である木材の利用が注目を集めている。その中でも特に、地産地消の概念に基づき地場木材の利用が推奨されている。本研究では、地場産木材を利用して高知県梼原町に建設される住宅を対象とし、原木の伐採から製材、建設地までの輸送工程のインベントリ分析を行う。これより、地場産木材の利用による環境負荷低減効果を考察する。

Various researches highlight that indoor air quality affects performance of workers in offices1). Although good indoor air quality improves work performance, it also increases energy consumption. In this study, we achieved a field survey in a real office in order to investigate the relationship between thermal environment, productivity, and energy consumption. In addition to the monitoring of indoor environmental quality and energy consumption, subjective experiments were conducted. In order to evaluate subjective performance, workers and students responded to questionnaires, and to evaluate objective performance, students simulated three types of office works. By calculating room temperature and worker's subjective performance, we demonstrate the correlation between room temperature and worker's performance (R=0.45, p<0.01). Results show that the room temperature that maximizes worker's performance was 25.6°C. It was also estimated that the equivalent 'quantity of work' of 8-hour work per day at 25.6°C can be achieved with minimum energy consumption in an environment where the room temperature is 27.3°C.

It has been observed that the indoor air quality of an office affects the productivity of its workers. Therefore, appropriate ventilation is essential to prevent the indoor air quality from deteriorating and to improve the productivity of the employees. It is also crucial to properly maintain the HVAC system in order to prevent it from an outbreak of microorganisms. In this paper, we conducted a field experiment in order to examine the effect of two different methods of maintaining the HVAC (cleaning the HVAC coil and increasing the outdoor-air supply rate) on the indoor air quality and on the workers' productivity. Our study confirmed that an adapted maintenance of the HVAC improved the indoor air quality, workers' satisfaction with the air environment, and their performance.

This paper demonstrates the effectiveness of eco-renovation and environmental education in improving the thermal environment in a school and reducing the environmental load produced by a school. We conducted thermal comfort and energy analysis in an elementary school in Iyo city, Ehime prefecture. In this analysis, we considered the thermal and ventilation network in the school and correlated them with the meteorological data of the region. The analytical accuracy and the effect of the abovementioned measures were determined. We observed that adequate eco-renovation and environmental education can improve the thermal environment by 19% and reduce the environmental load by 71%.

In order to develop the energy-efficient house in hot and humid region of Asia, the architectural devices provided to vernacular dwellings are considered to be useful. In this paper, the effect of the architectural devices of Indonesian traditional houses on indoor thermal environments, such as high-set floor and ship-shaped roof, are examined. Furthermore, the effect of employing the architectural devices to contemporary houses on cooling load reduction is calculated. The result shows the effectiveness of the architectural devices of vernacular dwellings.

In recent years, the environmental load attributed to energy consumption in office building sector is rapidly increasing. Therefore, promoting construction and diffusion of Sustainable Office Buildings (SB) is becoming urgent issue. In this study, authors have developed the diffusion model for SB based-on consciousness survey of building owners. This model enables us to evaluate an effect on SB diffusion in several cases where building owners are given incentives (ex. subsidization) for construction of SB. It is now possible to provide policy makers with useful information to promote SB.

These years residential energy consumption has been increasing sharply in China along with the high economic growth. Thus people pay much more attention to the issues of reducing the energy consumption and CO_2 emission. This study developed a Macro-model to forecast the CO_2 emission of residential buildings in China up to 2050. Former research reported results of Shanghai. And here we chose Beijing, the capital of China as another subject. By combining such Global warming count measures into the Macro-model it was able to forecast the CO_2 emission of Beijing's residential buildings in several energy-sufficient scenarios.
