In order to reduce the energy use of heat source equipment, it is important to evaluate their performance during operation and renovation. However, since there are few measurement parts of old equipment, analysis cannot be performed easily. In renovation and operation of old equipment, it is meaningful to perform the verification and estimation of effectiveness through simulations. Generally, a hospital has complicated energy consumption characteristics. In hospital A, Energy service company (ESCO) demonstrated renovation in 2012. Although the measurement points in this plant are not sufficient, the quantification of past performance is possible using a simulation tool. In addition, the energy efficiency of the heat source equipment after renovation was quantified. Moreover, for further efficiency improvement, the influence of an improvement of the chilled-water temperature difference between the supply and return was analyzed.

It shows about the application to the model building using the evaluation technique by the fixed-quantity logic. By the first paper proposes a new approach to risk assessment of buildings and facilities and summarizes the challenges in implementing such a method. What sets this assessment method apart from past risk management and reliability design methods is that this method employs an operational loss assessment index based on the degree of system damage and recovery conditions. This enables managers to make investment decisions based on the risk or likelihood of an event occurring when they formulate countermeasures to mitigate risk. Therefore, this paper (Part 2) explains the application to the model building through the evaluation technique using the fixed-quantity logic. It perform the lifeline by the great earthquake disaster and concrete examination about the influence on business continuation of building & facilities. Moreover, this paper shows a trial of the risk evaluation technique in the model building after having demonstrated the need of the risk evaluation technique using the fixed-quantity logic.

The influence of disturbances caused by relatively high temperature and/or traffic noise on the occupants' performance was investigated in this study. Since a disturbance can arouse human sensation, three tasks with different levels of complexity were assigned to experimental subjects. The subjects performed the above three types of tasks for 30 min. After conducting these tasks, the subjects assessed air quality, the general environment, SBS symptoms, thermal comfort, and subjective fatigue symptoms. As the results of this experiment, it was observed that the higher the noise level, the higher the work speed and accuracy of a simple task (task A). On the other hand, it was observed that the higher the noise level, the lower the work speed and accuracy of a complex task (task B). Furthermore, it was found that the higher the temperature, the lower the work speed, but not accuracy of task A. A relatively high temperature had an adverse influence on the performance of task B. The arousal with traffic noise could have a positive effect on a simple task and a negative effect on a complex task. In a relatively high temperature condition, the subjects felt more absentmindedness and reported that it was more difficult to concentrate.

The population density of workers in an office space causes one of the dominant heat loads, and hence the precise information on the time series of workers' population density in an office space is important for determining the boundary conditions of building energy simulation. In this study, we developed a simplified and inexpensive measuring system for workers entering/leaving an office space and validated its performance through field measurements. The measuring system for entering/leaving a room consisted of a Doppler sensor (micro wave), I/F circuit, and a communication program. Field measurements were conducted in the laboratory room of Kyushu University. The measuring system based on a Doppler sensor was confirmed to comprehend the potential uncertainty for accumulated error, and a correction method by integrating the time series of CO_2 concentration data was also proposed and validated. Finally, the results of the measuring system newly developed in this study showed a reasonably good agreement with the measurement results of digital video-recorded data.
