    Utilizing a zone model and a ceiling-jet model, a simple calculation method for predicting heat detector's response is presented. The parameters are the floor area and the ceiling height of the room, the radial distance of the detector from the fire axes, time history of the heat release rate of the fire, and the response characteristics of the detector. Application of the RTI-C model is discussed and a method utilizing two RTI's, one for the sensor element and the other for the detector body, is introduced. The method using two RTI's shows better results than the original RTI-C model, which is derived for predicting the response of sprinkler heads. In addition, a calculation method for predicting the response of rate-of-rise heat detector is presented. Overall performance of the prediction method is tested with experiments.

    The most popular lighting arrangement in Japanese housing has been one-lamp-per-room. This arrangement is excellent in producing uniform brightness, but it is not suitable for providing variations in brightness needed when occupants are engaged in various activities or for producing the desired atmosphere in the room. Use of multiple lamps has been proposed but has not been widely adopted for a lot of electricity. Considering the reason of the situation described above, in this study, we proposed a reasonable concept for distributed multiple-light arrangement for an improved residential environment and for energy conservation. We carried out an evaluation experiment based on the concept in the actual living and dining rooms.

    Jyodoji-Jyododo is one of the religious architectures that express the nobility of the Land of Happiness making use of daylight. The mechanism how the daylight reaches a statue of Amitabha-Tathagata in Jyodoji-Jyododo, it has peculiar luminous environment that no other historic architectures have, has not proved yet. Then, for the purpose of proving the mechanism of daylight that influence a statue of Amitabha-Tathagata, we conducted following 3 simulations; 1) Inter-reflection simulation with Jyodoji-Jyododo architectural model and simplified Amitabha-Tathagata model to obtain distribution of illuminance. 2) Specular reflection simulation for identifying the parts of the architecture which principally contribute to glitter of the statue. 3) Simulation of changing the angle of ceiling to make clear the relationship of the phenomenon and the architecture. From the results, we found that the daylight from the back of a statue of Amitabha-Tathagata repeats diffuse reflection, and a statue of Amitabha-Tathagata is shined by the daylight gathered at the ceiling. And the reason of a steeply slanting roof is infered that the daylight is took in a statue of Amitabha-Tathagata.

    Since the origin of the wooden house in Japan is a cold region, a constructor has the low consciousness to high air-tightness and performance thermal insulation of a house in warm areas, such as the Kyushu region. Moreover, in a warm area, the constructor does not recognize the danger of openings by the reasons of that the heat insulation construction according to the standard specifications of a wooden house is troublesome, becoming more expensive than the conventional construction cost, costing time and a labor. It was found, by means of field survey, that house wrapping sheets, vapor barriers, air barriers and insulating materials were not installed closely and many openings were brought about. When indoor wet air flows into a wall through these openings, dew condensation may occur inside a wall and wet air may reduce the durability and the safety of a structure object. Therefore, while clarifying importance of the airtight construction in the warm area, it is important for the danger of openings which generates internal condensation to be well-known, and to educate it at a constructor. It aims at clarifying importance of the airtight construction in the warm area in this research. The model experiment was conducted in order to solve an air diffusion phenomenon when differential pressure is minute.

    For prediction of auxiliary fan operating-ratio of a hybrid ventilation system, the wind pressure on building wall is indispensable. However, the wind direction and wind speed data presented by the local meteorological observatory is only hourly average value. In this research, the wind pressure predicted with the wind direction and wind speed hourly data by the local meteorological observatory was compared with the wind pressure measurements for every second step by step. This paper showed the directivity of examination on prediction of hourly-average pressure on building wall for hybrid ventilation system's auxiliary fan operating-ratio, and showed the correlation of each value.

    In this paper, two new indices, CRP1 and CRP2 (Contribution Ratio of Pollution Source 1 and 2), are proposed for evaluating the contribution of an indoor pollution source to human's breathing air quality. CRP1 refers to a ratio indicating how much of the contamination from a pollution source will be inhaled, and CRP2 refers to a ratio indicating how much of the total inhaled contaminant will be from a pollution source. Moreover, CFD methods for the two indices are developed to investigate the breathing air quality of a standing occupant or a lying occupant located in a stagnant room, which is assumed to be air-conditioned by means of displacement ventilation. The results indicate that in such a room, less of the contaminant from the above space will be inhaled by either standing or lying occupant, and it is important to make the floor clean for preventing breathing air from being polluted as expected.

    Recently, indoor air pollution caused by volatile organic compounds (VOCs) from building materials is known as sick building syndrome or multiple chemical sensitivity. As the countermeasure for this indoor air chemical pollution problems, building code was amended in 2002 and it was enforced in 2003. Labeling system of building material corresponding to formaldehyde emission rate is also started in Japan. Although the emission rate measurement with small test chamber based on JIS A 1901 has already been conducted, the existing methods for emission rate measurement require large-scale instruments and they are not always suitable for measuring a large number of building materials. This paper reports the results of numerical analysis of VOCs emission rate from building materials in various passive type flux measurement cell and the performance of these cells are to be clear. Furthermore, in order to supplement the emission rate data from various passive type flux measurement cell, we propose the index of effective diffusion length scale, 'L_d" and report on the analytical results.

    In an attempt to predict lifetime of charcoal filter designed to remove gaseous organic compounds in the air, authors have developed a model to simulate adsorption and desorption of multicomponent organic compounds in the filter. In adsorption equilibrium, this model is theoretically conformed of Dubinin-Astakhov equation. In order to give considerations to displacement adsorption phenomenon in lifetime prediction, this simulation model is designed to express the concept that organic compounds of different types share or compete to each other for the limited number of adsorption sites. Authors have validated this simulation model by comparing simulated and measured adsorption breakthrough curves for multicomponent system. Three types of charcoal filters are used in this validation. The prediction for the hydrocarbon is always satisfactory. However the adsorption capacity for the esters with middle boiling point is overestimated. Authors consider that this overestimation is due to neglect difference of affinity caused by dipole moment of adsorbate.

    One of the important subjects in commissioning for HVAC system is to improve control performance and time efficiency, while the selection of the optimal parameters to control HVAC system takes much time and labor in particular. We proposed a kind of commissioning technique as follows. We identified the dynamics of components of an actual VAV HVAC system such as rooms, VAV dampers, two way valves and chilled water coils, and verified the behaviors of the system on a personal computer and found the optimal PID parameters with a system identification method. Then we adopted the estimated optimal PID parameters to its actual system and ensured the system performance was fully satisfied. As a result, the proposed method showed to enable us to make commissioning effectively and to get system performances with the design intent.

    This research focuses on the plumbing of the drainage system with a disposer with the intention of collecting essential data regarding the evaluation of the system's performance and its design method. The authors have already examined and discussed the performance of the horizontal fixture drain branch and the drainage stack system. The next objective is to evaluate the house drain's performance to carry food wastewater and its design method. With the focus on the following two points, this research intends to acquire knowledge essential for the proposal of a method to evaluate the water-carrying performance of the house drain, which forms part of the drainage stack system with a disposer, as well as a method that enables efficient pipe cleaning and management. 1. Evaluate the house drain's performance to carry waste water by classifying types of remnants of food waste, and examine effects to the pipe flow and pipe performance by the flow volume of supply water, the amount of food waste disposed of and different floor levels in relation to load variation, from which identify supply water volumes and pipe flow rates appropriate for carrying waste water. 2. Remnants of ground food waste can be accumulated within a pipe, causing serious trouble by blocking the pipe. Simulate this condition using a simplified system model and identify load-carrying strength required in practical application.

    In order to obtain the fundamental information for discussing residential energy saving strategies, long-term investigation of detail energy consumption and indoor climate Have been done in 2002 to 2003 for 80 dwellings, including detached houses and apartments, in six districts of Japan. The occupant's behavior and building thermal performance were also investigated. Energy consumption for each appliance was measured as much as possible. This paper reports the description of all houses measured and the end use structure of annual energy consumption. The main results are following; 1) In Hokkaido, Tohoku and Hokuriku districts, the annual energy consumption for many houses was more than 60GJ but such houses were very few in other districts. 2) The houses measured in Hokkaido and Hokuriku districts consumed almost the same amount of energy for space heating, cooling and mechanical ventilation as that for hot water supply. But in other districts, the share of energy consumption for hot water supply is the largest. 3) The annual energy consumption increased with the decrease in annual mean outdoor temperature. But the contribution rate is not large as 0.4.

    In this study, office work productivity was evaluated by performance and fatigue. Experiments were conducted under Task and Ambient Lighting (TAL) system, to examine the effect of controlling illuminance level on work desk with task lights. Twelve male subjects were exposed in the experimental chamber conditioned at 25℃, 40%RH, and 700lx. Three conditions were compared, which were 700lx under Ambient Lighting system, 700lx under TAL system with controllable task lights, and 700lx under TAL system with uncontrollable task lights. When the subjects could not control the task lights, performance was significantly lower than that when they can control the task lights. Although there was no significant difference on the complaints of fatigue between controllable and uncontrollable task light, the correlation between fatigue and performance showed that 10% increase of complaints on fatigue might result in 6.5% decrease of performance. We also calculated the cost effectiveness of productivity in the case of this experiment. The cost effect increased by performance improvement was big because of the high personnel cost. The individual control system in the light environment was cost-effectiveness.

    In order to improve the thermal environment in outdoor space around residential buildings by greening, it is important to clarify not only the characteristics of transpiration rate but also leaf area density. The purpose of this study is to propose an indirect estimation method which is applicable to the field of architecture by comparing above two estimation methods in terms on leaf area density. 1) The leaf area density is the mean value for two points of east and west. 2) No leaf space is considered to calculate leaf area density around the upper parts of tree crown. 3) The correction factors are 2.2 in the upper parts and 1.3 in the south lower parts of tree crown.

    This paper describes support environment for architectural design collaboration between distributed members. Collaboration projects via Internet have been held between educational institutions due to emergence of Internet and computer technologies. Our research group has carried out eight projects since 1996, and has developed typical collaboration support systems effectively to access to database of design information, to share design process, to teach architecture. In this paper, the authors focus on activating member's interaction, discuss its importance for creative process, and develop two support systems, both of which enhance the awareness in asynchronous communication. One named AMPIS is for accelerating interaction by using Internet connected mobile phone. Another promotes "remarking on design idea each other" by adding Tag-label metaphor interface to Digital Design Pinup Board. From analysis of logged data of case study projects (DCW2001, 2003) and survey, the authors clear performance of proposed systems as followings; 1) AMPIS effects controlling response-time of member's interaction and facilitating information exchange in asynchronous group work, 2) Tag-label interface promotes exchanging opinions and provides awareness toward context of design ideas or discussion.
