This paper will report the survey of energy and water consumption in the high-rise office building in Osaka with environmental symbiosis technologies. Firstly, energy consumption of the building during 4-years after the completion of construction is investigated. Secondly, energy consumption except special area is compared to the one in the standard office building. And finally, water consumption of the building is investigated. As a result, the decrease of annual energy consumption is estimated by 30% and above in comparison with a standard office building. The growth of water consumption is related to the increase of numbers in the building.

For the purpose of grasping operational condition, air conditioning load and the energy consumption, we have conducted the observed survey of the environmentally conscious building completed on 1999. This study has been done for a year of 2007. Throughout the year survey, especially the middle season, we found out the natural ventilation has been fully utilized. The following report shows our designed facility has been functionally operated as energy consumption building and actual survey number express the less operation time and energy consumption for the air conditioning.

We researched the design process of building. Firstly, we investigated a general building design process of 7 general contractors and an architect office. We categorized 8 general building design processes by the number of design process separators and essential stylized checking, we put them into 6 types and showed their characteristics. In addition, we focused the environmental friendly matters in the design process, compared the general design process with an actual design case. To facilitate design process; cooperation and consensus-building, we obtained the suggestion that we have the necessity to research on what terms the environmental consideration matters are adopted.

In this study, questionnaire survey has been carried out to find out the actual usage condition of energy consumption during 2008 in Sendai. Energy consumptions for space heating/cooling, hot water supply and others (kitchens/ entertainment information / housework and hygiene / lighting) have been calculated by using existing prediction models. The calculation result of space heating was about 10GJ larger than the questionnaire survey. The existing prediction model showed a big difference with the actual result and thus, accuracy improvement has been made to the existing models.

This study carried out a multiple-regression analysis to investigate the relationship between properties of office buildings and the energy consumption per floor area. This study also performed simulations to estimate monthly energy consumption of 31 office buildings using available building property data. The result was compared with the simulation results each estimated with different datasets in which a building property or a combination of properties is neglected. By comparing the results with different datasets, this study quantified the extent to which the neglected building properties influence the energy consumption of office buildings.

To effectively dissemination energy-conservation measures into the commercial sector, the understanding of the structure of energy use is crucial. We surveyed monthly energy consumption of small retails and restaurants and analyzed the relationship with elements potentially affecting the energy consumption by a multiple regression analysis. We found that for retails the operation of space and energy consuming appliances used for delivering their service (e.g. capacity of lighting and refrigeration showcase) accounts for the variation in the energy consumption. In addition to these factors, the energy consumption of restaurants heavily depends on the number of guests and energy consumption for delivering their service per guest.

In order to improve thermal condition in classrooms of metropolitan high school, air-conditioners were installed to all classrooms in 2008. It requires much more energy and cost so that effective energy saving should be considered. As a solution, this paper presents the new method that controls many fun coil units according to a timetable of school. Before the application of such control system, every 10 minutes state of air conditioners for high school class rooms was measured. The results suggest that a plenty of energy can be saved by this system.

The system is installed at Collaboration of Technology Center, of Miyagi National College of Technology. The accumulation of expertise of the construction, tuning, operation in many usages of buildings may offer the simplified systems at some levels, that is, CO2 generation, energy consumption, comfort and cost. Also the typical operation schedules according to the climate may be available.

Recently it has become easier to notice the excess energy of the energy distribution system in buildings with the aid of BEMS. The aim of this study is to adjust the control parameters and the device settings for effective operation of series pump system in HVAC systems. The energy consumption of two major control methods is studied with the facility and the effect of setting status of control parameters on the energy consumption are revealed. Improvement methods are proposed from the experimental results.

In recent years, the ministries and local governments have been regulating CO2 emission for targeted companies tightly. On the other hand, the companies have the basic needs for reducing cost. Therefore, the optimizing model has been developed to minimize both the cost for energy facilities and its operation schedule with achieving the amount of their CO2 reduction target. This model can calculate the practical cost by referencing real electricity and gas rate table. This paper reports the results of case study on both the cost and CO2 reduction effects in the hospital.

This paper describes the energy-saving effects and reduction of user's benefits based on the results of monitored power consumption of elevators and computer-simulation. Target energy-saving activities are: 1) reducing the number of operating elevators, 2) let passengers whose traveling distance is small use stairs. Major findings can be summarized as follows: 1) Cutting the number of elevators reduce power consumption but increases the moving time of users very much. 2) Using stairs positively contributes reducing total moving times rather than reducing power consumption of elevator.

The energy consumed in the office building and the efficiency of the air-conditioning were evaluated by using the simulation tool and the BEMS data. As a result, it was shown that the simulation tool was effective as the criterion of managing energy in the building. Then, it was confirmed that using the simulation tool enabled the comparison of plans to reduce the energy consumed.

AJINOMOTO CO., INC. FOOD PRODUCTS GLOBAL R&D CENTER was built to consolidate food R&D divisions scattered in the establishment to integrate individual knowledge and to conduct cutting-edge R&D. In this building we adopted various energy-saving systems, such as thin double glazing system called the Compact double screen, Cool Pit, TAS CLEAN AHU (washable AHU), high-efficiency refrigerating system, and so on. And we report the efficiency of these energy-saving systems examined after the completion of construction.

Small and medium size office buildings account for the majority of the total energy consumption of all the office buildings in Japan. Energy saving for these buildings have not been implemented enough compared to large size office buildings, and simple and practical measures should be promoted. Y building, completed in March 2009, was designed based on the following concepts. ・Optimal design of air conditioning capacity to reduce low load operation. ・On/off control of lighting and air conditioning in the office space by occupancy sensors. The effects of above two concepts are to be examined this year.
