  • 〔Major achievements〕Analysis of the impact of regional temperature pattern on the energy consumption in the commercial sector in Japan
    Yujiro Hirano; Kei Gomi; Shogo Nakamura; Yukiko Yoshida; Daisuke Narumi; Tsuyoshi Fujita, We conducted this study to clarify the impact of regional climatic conditions on the energy consumption in the commercial sector, in Japan. For this research, we utilized the Database for the Energy Consumption of Commercial Buildings (DECC), which provided data on the individual buildings. The existing energy consumption pattern derived from the individual building data seems to have large variations depending on climatic conditions. Therefore, in this research, connections were made between the seasonal fluctuations in energy consumption as well as the seasonal temperature changes, in order to extract the components of variation due to temperature, and make a regional comparison. In addition, we prepared estimating equations for the energy consumption based on temperature. By applying the regional temperature data to these equations, the impact of temperature alone was extracted for comparison. The results showed that, for the types of buildings addressed in this research, even though there is a regionality to the ratio of increments during summer and winter with regard to heating and cooling, it is offset by summing them up. In this research, we were able to roughly determine the level of fluctuations in the energy consumption as an impact of temperature. (C) 2017 Elsevier B.V. All rights reserved., ELSEVIER SCIENCE SA

  • 〔Major achievements〕Strategies for a sustainable campus in Osaka University
    Yukiko Yoshida; Yoshiyuki Shimoda; Takumi Ohashi, Lead, This paper reports strategies toward achieving a sustainable campus at Osaka University, Japan. We advance a daily energy-use schedule for each building type to provide effective energy-saving strategies. We classify the facilities into three categories according to department type to reveal their energy-use patterns and identify their strategies for saving energy. These strategies will contribute to a sustainable campus using photovoltaic generation. Not only the implementation of energy-saving technologies but also the installation of renewable energy technologies will realize a sustainable campus at Osaka University. Category I (liberal arts) buildings have low energy density. The energy efficiency strategy for Category I is to develop zero-energy buildings by tuning the energy system to people's daily routines. Category II (science and engineering) buildings have high energy density. The energy efficiency strategy for Category II is effective energy conservation using the plan-do-check-act cycle. Category III buildings are large-scale facilities with experimental laboratories. The energy efficiency strategy for Category III is outsourcing energy management to an energy service company. Compared with fiscal year 2010, in 2015 Osaka University decreased energy use per unit floor space by 22%. It achieved these savings despite an increase in total floor area during that period.

  • 〔Major achievements〕Assessing the effects of CO2 reduction strategies on heat islands in urban areas
    Yujiro Hirano; Yukiko Yoshida, Last, There has been a wide range of low-carbon solutions proposed to mitigate climate change. However, such measures must be compatible with the local environment and living standards of residents to be brought to fruition. Measures that adversely affect residential environments will be difficult to implement, so the impacts of measures on the local environment must be taken into consideration during implementation. This study assessed the effects on urban heat islands of efforts to reduce CO2 emissions, as one environmental impact associated with climate change. A simulated assessment was conducted, using an urban canopy model coupled with a building energy model (CM-BEM), to evaluate the effects of five specific measures: solar shading of windows using curtains and blinds, improvement of the thermal insulation of building walls and roof surfaces, implementation of energy-saving measures related to indoor appliances, installation of solar photovoltaic (PV) panels, and adjustment of preset cooling temperatures. The study focused on these effects as they occur within typical urban districts of office buildings, fire-resistant housing, and wooden housing. Results indicated that many of the energy-saving measures have slight temperature lowering effects, but solar panel installation and improved heat insulation, both associated with changes in surface heat balances, tend to raise daytime temperatures to some extent. However, effects on daytime temperatures were in the range of 0.1-0.2 degrees C and, as such, none of the CO2 reduction measures considered was deemed a significant factor in raising urban temperatures.

  • 〔Major achievements〕Estimating residential CO2 emissions based on daily activities and consideration of methods to reduce emissions
    Yujiro Hirano; Tomohiko Ihara; Yukiko Yoshida, Last, To achieve a low-carbon society, it is crucial to make the transition away from wasteful lifestyles that are shaped by mass production/mass consumption towards low-carbon lifestyles. Research in the field of urban environmental studies examining human behavioral factors affecting energy consumption, has mostly focused on CO2 emissions relating to direct energy consumption, such as the use of air conditioners and water heaters. As CO2 emissions from the industrial sector are greater than those from the residential and transportation sectors in Japan, it would be prudent for consumers to work on reducing CO2 emissions relating to products and services. In an effort to provide some basic research to achieve the aforementioned objectives, this study looked at statistical data from sources such as the Japanese Family Income and Expenditure Survey and the Japanese National Survey of Family Income and Expenditure to estimate direct and indirect CO2 emissions relating to daily expenditures and consumption. As a case study, we selected a sample denizen to calculate the CO2 emissions relating to daily living. Based on the obtained results, we examined the lifestyle and consumption patterns and their relation to CO2 emissions. The results suggest that while it is still important for consumers to reduce their direct energy consumption in an effort to create a low-carbon society, there is still potential for indirect CO2 emission reductions in areas of production and consumption.

  • 〔Major achievements〕The effect of window opening area on the indoor thermal environment of Japanese housing with cross ventilation　　　　　　　　　　　　　　　
    Sayako Kishi; Teruyuki Saito; Satoru Kuno; Yukiko Yoshida; Saki Ota; Mayumi Mimura, It is important to improve the energy efficiency of housing both to reduce energy consumption and to maintain thermal comfort. Cross ventilation is useful for this purpose: efficient cross ventilation can reduce air conditioning and energy consumption, while improving thermal comfort. This paper focuses on the design of cross ventilation in housing and the influence of opening area of inlet and outlet windows by conducting field experiments using an actual house. The ratio of effective opening area Ss/Sn, which is the ratio of the area of inlet windows to the area of outlet windows, is used as the index of opening area. The experiments were conducted for five values of Ss/Sn ranging from 1.0 to 8.9. The results show that it may be better to vary the pattern of opening windows depending on whether the outdoor temperature is lower than 27.0-29.0°C in order to use cross ventilation efficiently., International Society of Indoor Air Quality and Climate

  • 〔Major achievements〕STUDY ON THE IMPROVEMENT OF AIR CONDITIONING SYSTEM USING MATHEMATICAL PRINCIPLE METHOD CONTROL TECHNOLOGY
    YOSHIDA Yukiko; FUJINUMA Yasumi, Lead, Building and Energy Management System (BEMS) has being focused on climate change mitigation in the IPCC 4th report. In order to reduce CO2 emissions in commercial sector in Japan, the project driven by NIES, National Institute for Environmental Studies, has developed the next generation BEMS that is configured with the environment measurement, the calculation of building energy and mathematical planning, and equipment control. This study is performed as a part of air conditioning control system development by real time heat load and system simulation in the real building. Regional forecast weather data, number of persons staying in the room and electricity consumption are fed to this simulation for input data. Several sensors are set in this building for feeding input data of real time simulation. We studied the energy consumption of the office to simulate and forecast the energy saving and evaluated an office model using indoor air-conditioning control system. We tried to optimal control for the indoor office model., Architectural Institute of Japan

  • 〔Major achievements〕Short Circuit and Mixing Loss due to Inappropriate Layout of Openings for HVAC system
    近藤靖史; 小笠原岳; 太田恭兵; 神村一幸; XU Guohai; 吉田友紀子, Last, Several types of ceiling air diffuser form the attached air jet along the ceiling which diffuses throughout a room. However, if the layout of supply openings and exhaust ones is not appropriate, the short circuit between them appears and ventilation/air-conditioning efficiency becomes very low. Additionally mixing loss between interior zone and perimeter zone may occur and make energy consumption. In this paper, flow visualization test was conducted in the office and the problems described above were confirmed. Then CFD simulations were carried out to study adequate layout of openings for HVAC system., The Society of Heating, Air-Conditioning & Sanitary Engineers of Japan

  • 〔Major achievements〕Development of air conditioning technologies to reduce CO2 emissions in the commercial sector
    Yukiko Yoshida, Lead, Background: Architectural methods that take into account global environmental conservation generally concentrate on mitigating the heat load of buildings. Here, we evaluate the reduction of carbon dioxide (CO2) emissions that can be achieved by improving heating, ventilating, and air conditioning (HVAC) technologies. Results: The Climate Change Research Hall (CCRH) of the National Institute for Environmental Studies (NIES) is used as a case study. CCRH was built in line with the "Green Government Buildings" program of the Government Buildings Department at the Ministry of Land, Infrastructure and Transport in Japan. We have assessed the technology used in this building, and found that there is a possibility to reduce energy consumption in the HVAC system by 30%. Conclusion: Saving energy reduces CO2 emissions in the commercial sector, although emission factors depend on the country or region. Consequently, energy savings potential may serve as a criterion in selecting HVAC technologies with respect to emission reduction targets. © 2006 Yoshida
