    This paper examines a method for calculating the thermal performance of curtain walling with frames. A general calculation method was used for obtaining thermal insulation and sun shading performances of curtain walling by referring to ISO and existing investigation. As there have been no fixed calculation methods and the range of modeling frames has not been clearly defined so far, it was not possible to identify thermal performance of curtain walling. Due to this, it has been often the case that the thermal performance of it is calculated assuming that curtain walling is a simple wall consisting of opening units as glazing and spandrel panels as panel materials. As a result of calculating thermal insulation and sun shading performances, the degree of affecting frames, glazing and spandrel panels to them has been made clear. Especially, the necessity for considering the frame in evaluating the thermal insulation performance became clear.

    In hot and humid area, it is quite important to develop a space cooling system which realize the both of low exergy consumption and thermal comfort. The purpose of this paper is to grasp how the low-exergy cooling system of the combination between a radiative panel and pre-cooling of ventilation air using well water can realize the both of low exergy consumption and thermal comfort. Followings were found by a field testing at the environmentally-conscious model house where the system is installed and a computer simulation. The ratio of the period SET* varies 22-26°C is 73.3% in the case both of radiative cooling and pre-cooling of ventilation air were executed. The electricity use of the developed cooling system working all day is equivalent to 21.6% of that of air conditioning with set point temperature 29°C.

    In previous studies, a batch-type desiccant air-conditioning system placed in the floor cavity was proposed which is able to operate perennially in both cooling-dehumidification and heating-humidification modes with ventilation. And a numerical analysis model to estimate the performance of the proposed system was developed.
    In this paper, a sensitivity analysis was conducted with design-parameters such as temperature of hot and cold water, mass flow rate of hot and cold water, air flow rate, quantity of desiccant, quantity of thermal energy storage material and transposed interval. by using the developed numerical analysis model. In order to verify the role of thermal energy storage tank, a comparative numerical analysis with or without a thermal energy storage tank was conducted. And the adaptability of the large humidity-control capacity to latent load was evaluated.

    The thermal performances of two types of Building Structure Thermal Storage HVAC system, the Ceiling Plenum type (SC) and Underfloor Plenum type (SF), were analyzed through real scale experiments under maximum cooling loads. Subsequently, they were compared with the performances of the ordinary HVAC systems without heat storage, with the ceiling air supply system (OC) and underfloor air supply system (OF) operated with and without pre-cooling operating hours. The results obtained were as follows:
    1) The SF system, that provides heat storage during the nighttime, in some cases supplies the stored heat inconveniently to building structures in the daytime cooling mode. Therefore the total daily loads for the SF system is greater for than the SC system. However, it reduces the cooling loads in the daytime.
    2) The pre-cooling operating mode in both the OC system and OF system is effective for the reduction of cooling loads in the daytime, but slightly inferior to the operation of the SC system and SF system.

    An energy calculation model for hot water based heat pump was developed. In this model, the theoretical heat pump cycle efficiency can be calculated based on the condensation refrigerant temperature and the evaporation refrigerant temperature, which can be presumed from the operating condition and the thermal output, and then the actual efficiency of the heat pump under various operating conditions can be calculated by modifying the theoretical heat pump cycle efficiency, considering heat loss form the refrigerant pipes, the degradation of the compressor efficiency, and the auxiliary power consumption. We showed the possibility that the actual efficiency and the power could be calculated when three coefficients in the developed model could be identified appropriately.

    The amount of architectural scrap wood of 6 cities in Nagano Prefecture was investigated. Next, to plan the effective use of architectural scrap wood, the amount of future recycling was projected. It was estimated that the amount of architectural scrap wood generated in Nagano Prefecture was 113,116t a year between fiscal year 2004 and 2008. Moreover, the recycling rate was found to be 81.0% from investigations of the current state of the processing and disposal of waste wood in Nagano Prefecture. It was forecast that the amount of recycling of architectural scrap wood will increase from 2008 to 2035 and decrease from 2036 to 2050 in Nagano City.

    To promote ventilation in the street canyon is one of the effective urban heat island measures. The analysis on the relationship between properties of urban block and wind environment in the street canyon is required. In this study, relationship between wind environment in the street canyon and characteristics of urban block e.g. building cover ratio, variation of building heights, as well as roadside properties e.g. direction of street, width of street, height of building, is studied by CFD simulation results carried out in the central Osaka city. Ventilation in the street canyon is promoted by positive and negative pressure areas which are formed by variation of building heights. Both "the vertical wind path" caused by high-rise building and "the horizontal wind path" formed along the wide road parallel to upper wind direction should be considered for the improvement of ventilation in the street canyon. It is also confirmed that the attention to windward and downwind areas should be noted.

    This paper examines the relationship between the greenery condition in a new planned residential area and the changes in the residents' consciousness toward the greenery and living environment in three years after moving. The multi-year questionnaire surveys for resident's consciousness are conducted and the database of the greenery condition is used for analysis. The results indicate that the changes in the residents' affection toward the living environment have related to variation of the greenery in the landscape and the number of the greenery in each residence.

    The number of patients with heat stroke, sleep disorder and heat shock caused by poor indoor condition increased, becoming a major social issue. As the house is the base of life, the improvement of residential environment that supports resident's health is a pressing issue. This study figured out the effect of residential environment on resident's health and developed the residential environment assessment tool for health promotion. Then, verified the effectiveness of this tool. People recognize the level of their house and notice the risk factors of disease in their house through the evaluation result with this tool. It will be highly motivating for them to improve the residential environment for health promotion.

    This study is a part of the project that aims to construct the database for energy consumption of commercial buildings on the national scale. The purpose of this study is to obtain the basic data for energy consumption in the welfare facilities for the most of aged persons. The authors classified the buildings into two types of the residential and non-residential facility, and showed the attributes and energy consumption in each type. On the basis of these results, the factors that will have effect on the energy consumption for the unit of floor area in each type were clarified by the technique of multiple regression analysis. Furthermore, the relationships between the outside mean air temperature in each area and the monthly mean energy consumption in each facility were analyzed. After the monthly values of energy consumption were classified into the non-varied part through a year and the varied parts in summer and winter, the effect of the outside air temperature on each part was clarified by the multiple regression analysis.
