    It is important to promote energy-saving actions toward the reduction of CO2 emissions in residential sector. Residents should understand the actual conditions of energy consumption in their home in order to make energy-saving actions more effective. Therefore, in this research, a tool which suggests effective energy-saving actions was developed based on literature research and questionnaire survey. A workshop was conducted in Kawasaki City. Then, the residents received the information of their actual energy usage and effective energy-saving actions suggested by the aforementioned tool. As a result, 6.4% of CO2 reduction was achieved.

    Recently, not only running CO2 consumption but also initial CO2 reduction has been important. In Japan, LCCM (Life cycle carbon minus) is a keyword of sustainable buildings. In LCCM buildings, many efforts to reduce CO2 (such as high thermal insulation, high efficient equipment, and so on) are adopted and Photovoltaic system can return more amount of CO2 than CO2 which is consumed in buildings. According to such principal, LCCM demonstration house were built in 2011. We have checking the performance of this house by experimental residence.

    The revised Building Standard Act recommends that continuous ventilation systems must be used in Japanese residences. In this study, questionnaires were distributed regarding the use of continuous ventilation systems in detached residences in the Kansai area. We analyzed 88 questionnaires completed by architects and 76 questionnaires completed by residents. The results showed that the opinions of architects had a significant influence on the use of a continuous ventilation system in residences. In addition, it was found that the continuous ventilation system was stopped because of the inflow of outdoor air or because of minding the electricity bill.

    Temporary housing is typically very systematic and plain, due to the fact that in almost all cases its construction must be urgently finished. However, this type of housing is lacking in the viewpoint of building community and in consideration for elderly and handicapped people. We proposed ‘Community-Care Temporary-Housing’. Concepts are as follows;
    1. Old community was well considered on the new house allocation.
    2. Each building consists of variety of floor-type.
    3. Support center and temporary shops were installed.
    4. Wooden deck connects each entrance without gap.
    5. Every entrance faces each other.
    6. Living-room is open to wooden deck.

Almost of school districts have one or two facilities, regardless of the nursery number. Convenience is high and sufficiency is low in city areas, on the other hand convenience is low and sufficiency is high in rural areas, because the district area is large and the number of infants is small. It is important to examine the facility planning suited to area conditions by making use of existing buildings and regional talents.

    Although terrace seating is widely recognized as a contributor to urban liveliness, in Japan it is strictly restricted by regulations. This paper examines two types of outdoor seating in Tokyo: cafés in Daikanyama located on private land plots, and Japanese-style taverns in Yurakucho illegally located on the public street. The results show the spatial characteristics and actual usage of these two types, and suggest the necessity to develop guidelines adapted to diverse urban situations in order to support street life.

    This paper describes a methodology for finding and defining the planning units applicable to landscape planning. Based on the topographical analysis focusing on basin, this methodology clarifies the sequence of scenery and the structural principle of landscape planning unit. This principle is derived from the analysis of ridge line network which works as unclosed border line of landscape units or the connector of sequential territories of landscape. Simplicity of its analytical procedure helps local people get agreement to the plan and promote collaboration to solve the problems on landscape in their community and with its adjacent communities.

    Current lighting control systems mostly rely on motion sensors. However, the measurement range of the motion sensors is not large so that delicate lighting control is not possible. In this paper, we propose an LED lighting control system consisting of Kinect, a sensor agent robot and LED light bulbs with the wireless network system. Kinect can capture the human motion and the senor agent robot “e-bio” can follow a human. The proposed system counts the number of persons in the room and their positions. The gathered information is used for lighting control.

    In order that passengers can behave more spontaneously in a station, it is necessary to grasp the situation of the whole station and offer better service which suit various behaviors. Now, there is no method of grasping the situation everywhere in a station which is a complicated space. The human behavior in partial space can be grasped by using apparatus for exclusive use. We supposed that by using this partial grasps the situation of the whole station can be predicted in real time. The process is as follows. First, we acquired a passenger’s position coordinate by the surveillance camera of the station yard. Next, we indicated movement of the passenger to the dead angle portion which has not been caught with a surveillance camera as a probability. Finally, we propose the model for grasping the state of the whole station yard. In thus appears that the situation of the whole station can be predicted in real time by the situation of partial space.
