    A Food Supply and Demand Assessment Uder the Future Global Warming Uing GIS
    (Informatics for Environmental Protection - Networking Environmental Information, 2005) Mori, Shunsuke; Doi, Takahiro; Ido, akafumi; Kato, Masahiro; Morimoto, Shinichiro
    It is now well understood that the global warming will affect the agricultural production through the changes of ecological systems and the damages of land by sea-level rise, although the warmer climate and the higher concentration of CO2 contribute to the photosynthesis of the crops due to the potential loss of cropland and the precipitation change. High temperature damage on the rice production should also be taken into account. While many assessment investigations on the food supply potential have been developed, few have achieved the food demand considering the changes of dietary issues. This study aims at the assessment of the future demand-supply interactions under the future global warming using GIS. The current study shows us that although the global warming could contribute to the world food production, the negative impacts will appear in the developing regions and thus both the land and water management issue and the distribution of food issue will become more important.

    A GIS-based Model for the Assessment of Energy and Environmental Contributions of Distributed Energy Systems
    (Managing Environmental Knowledge, 2006) Mori, Shunsuke; Ito, Junichi; Ishida, Takeshi; Morimoto, Shinichiro
    Cogeneration systems (CGS) and District Heating Systems (DHC) are often expected to contribute to the energy conservation and CO2 emission reduction in the commercial and residential buildings. However, since the contribution strongly depends on the regional conditions as well as the energy demand patterns, existing assessments have mainly dealt with the certain building or a district. In this paper, to evaluate the potential reduction of CGS and DHC more generally, we develop a GIS based energy system assessment model. We pick up seven regions of Utsunomiya-city which locates near Tokyo and has 450 thousand inhabitants, as a typical mid-size city of Japan. Applying GIS, we evaluate detailed energy demand statistics, which are then transferred to the energy flow model taking into account the properties of the energy equipments. The outputs of the model are then applied to estimate the potential contribution of the distributed energy systems to the whole Utsunomiya city.

    A Model for the Evaluation of Potential Energy Conservation of Data Center Focusing on the Air Conditioning Options in Japan
    (Innovations in Sharing Environmental Observations and Information, 2011) Mori, Shunsuke; Ohkura, Masashi; Ohkura, Hidetaka
    The importance of carbon emission reduction is now broadly understood. After the gigantic earthquake on March, 11, 2011, the first priority issue for Japan is the recovery of the society and economy. However, most of the energy conservation options for the global warming mitigation are applicable under the energy constraints. Until today, the impacts of information and communication (ICT) industry have not been well addressed. In Japan, Ministry of Internal Affairs and Communications(MIC) has assessed that the power consumption for the air-conditioning of data centre (DC) indicates 17% of total power demand for ICT. In this study, we develop an optimization model considering the temperature and humidity conditions for DC with 2000 racks in Tokyo and Sapporo including - Cogeneration systems - LNG vaporizer to utilize the evaporating heat - Photovoltaic cell (PV) - Ambient air intake - Turbo refrigerator - Humidifier The results show that 23.9% and 11.9% of CO2 emission could be reduced by introducing photovoltaic cells and humidifier in Tokyo and Sapporo, respectively. The ambient air is largely utilized in Tokyo except for summer while it is not mainly utilized in Sapporo due to the low humidity. Thus, humidifier in Sapporo contributes to reducing CO2 emission in Sapporo. Key Word: data centre, energy conservation, ambient air, LNG vaporizer, humidity control

    An Analysis of Regional Energy Demand and an Assessment of Potential CO2 Emission Reduction in Japan Using GIS
    (Environmental Informatics and Systems Research, 2007) Mori, Shunsuke; Koike, Shogen; Ishida, Takeshi
    This paper aims at the estimation of the contributions of distributed power systems to CO2 emission reduction and cost saving concretely by region of Japan. In our previous work (Mori, 2006), we picked up a medium city Utsunomiya which is located in the centre of Japan to evaluate the potential contribution of heat pump(HP), cogeneration system(CGS), district heating system (DHC) and their optimal combination to reduce CO2 emission. Since demand patterns on heat and electricity vary among consumer types and climate conditions, it is not applicable to evaluate the whole contribution of the above energy equipments to the CO2 emission reduction for Japan. In this paper, as an extension of our previous work, we applied the method to Sapporo and Okinawa located in north and south part of Japan and evaluate the potential contribution of them. We found a linear relationship between the ratio of commercial building floor area to total building floor area and potential CO2 reduction rate in case of full option and HP case in spite of the large difference of climate conditions. Assuming that the relationship between density of residential building area and the distance from the center of the city of Utsunomiya holds in other regions, we evaluate the potential CO2 reduction of the new energy equipments for 950 Japan cities where 18.6% CO2 emission reduction potential in total is indicated. Although there remain many issues in our study, this is the first estimation on the contribution of DHC, CGS and HP considering the partial load properties and GIS based detailed building data.

    An Analysis of the Relationships between IT Investments and the Industrial Structure Change in Japan Using Input-Output Tables – Historical Analysis and Future Projection1-
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Saito, Makoto; Mori, Shunsuke; Dowaki, Kiyoshi
    The effects of IT on the environment and the economy have broadly been discussed. However, most of the case studies were descriptive due to the lack of data and methods. This paper proposes a method to evaluate the industry structure changes based on the Input-Output analysis developing an extended multivariate analysis. Revising our previous work, we provide the future projection including the estimation of the historical software investments. The results demonstrate the significant contributions of IT in the structural changes in Japan’s economy.

    Data Centre as a Key Player of a District Electric Power and Heat Network System; comparison in Urban and Suburb Regions
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Mori, Shunsuke; Hori, Yuuki; Ohkura, Masashi; Kamegai, Kazuhisa
    A data center(DC) demands air-conditioning power as large as the 1/3-1/2 of total electricity consumption.Thus, energy saving of cooling power of DC yields considerable effect on both economic and environmental views.Photovoltaic (PV) and absorption refrigerator with gas boiler or cogeneration systems(CGS) are possible power saving options. The waste warm air from DC would be utilized for greenhouse heating when DC and greenhouse locate near in the suburbs. In this study, the authors develop an energy network model to assess the potential contribution of DC as a major electric power and chilled air consumer as well as the warm air supplier in a district to the energy efficiency improvement. The evaporation heat of LNG utilization is also considered as well as PV, CGS. This model is applied to the cases of the urban area in Tokyo which involves athletic center, shops and hospital and the suburbs including greenhouse and then compared. Key word: data center, distributed energy systems, urban and suburbs

    Integrated Assessment Model for Urban Energy Network System
    (Environmental Informatics and Industrial Ecology, 2008) Ishida, Takeshi; Mori, Shunsuke
    We have constructed a model to evaluate a distributed energy supply network system in an urban district and have evaluated an actual urban district in Utsunomiya, a mid-size city in Japan. This model enables us to deduce an energy-saving plan through energy exchange between residential and commercial buildings in the district. We conducted a case study in the actual urban district and examined the possibility of energy saving and CO2 reduction. From GIS data, we calculated the floor space and building space. Then using the model, we then estimated the energy load of each building and calculated the total energy load of the urban district. We evaluated the potential CO2 reduction as well we energy savings under the following three cases: case 1—installing a cogeneration system (CGS) in each building, case 2—installing a CGS in each building and an energy exchange network connecting the buildings, and case 3—the installation of a CGS and an energy exchange network with the minimum purchase of electricity to the district. The evaluated results indicated the installation capacity and operating conditions of the network system, considering the surplus electric power of photovoltaic systems and CGSs. Further, for case 2, the energy consumption to be reduced by approximately 2% comparing with case 1.
