     View Summary

    &nbsp;In recent years after IPCC Fifth Assessment Report, strategies of not only mitigation but also adaptation are being focused for responding to climate change. The report has predicted that the average temperature would be rise by up to 4.8 &deg;C from now by the end of the 21st century if the current level of Greenhouse gas emission is continued. To prepare global warming, recent studies have estimated the impact of climate change on heating and cooling energy by utilizing future meteorological data.<br>&nbsp;In this context, Japanese government has recently published a database called &ldquo;Database for Policy Decision-Making for Future Climate Change&rdquo; (hereafter d4PDF) to be used researches for impact assessment studies and adaptation planning for global warming. building and urban energy sectors of Japan should utilize these weather prediction data to examine the impact of climate change and prepare adaptation strategies.<br>&nbsp;Therefore, this study aims to predict heating and cooling demand after a mean temperature increase of 4&deg;C (hereafter 4&deg;C-rise temperature) and analyze its effect on heating and cooling system by estimating system COP, total and peak energy demand, and amount of discharged heat and cooling tower makeup water with the d4PDF data. This study is based on the steam demand and the chilled water demand in Minatomirai 21 Area (hereafter MM21 Area) to reflect conditions of actual heating and cooling system.<br>&nbsp;To do this, this study conducted three steps: derivation of regression analysis equations, prediction of heating and cooling demand, and examination of influence on heating and cooling system.<br>&nbsp;The first step derived regression analysis equations between mean temperatures and the steam and chilled water demands in MM21 Area of 2014. The regression analysis equations are to predict the heating and cooling demand after 4&deg;C-rise temperature.<br>&nbsp;The second step estimated the fluctuation range of heating and cooling demand after 4&deg;C Global warming of d4PDF. Compared with the average year, the steam demand decreases to 70.7% to 77.2% and the chilled water demand increases to 147.9% to 163.4%. In the weather of the top 5% of 4&deg;C-rise temperature, the chilled water demand in August goes up 169.5% compared with the average year. The full load equivalent hour of steam and chilled water becomes 99.1% to 105.2% and 106.7% to 115.1% respectively, compared to the average year.<br>&nbsp;The third step examined the influence on the heating and cooling system of MM21 Area. The electric power consumption rises to 140.5% to 152.5% and the gas consumption is the similar level of the average year, 98.8% to 100.8%. Therefore, the annual primary energy consumption grows to 114.8% to 122.0% compared the average year. COP stays on the similar level of the average year and CO2 emission increases by 5.0% to 6.9% more than the average year<br>&nbsp;In the weather, the top 5% of 4&deg;C-rise temperature in August, the daily primary energy consumption rises to 162.0% compared the average year. Because of the increased cooling demand, the annual discharged heat and the annual cooling tower makeup water grow to 156.9% to 172.6%, compared with the average year. the peak of discharged heat is calculated at 165.3%.

     View Summary

    <p>In this study, in order to continuously supply electricity and steam to fishery related industries in a disaster, and to supply electricity to important facilities in the area, LNG satellite supply, Co-generation system (CGS) and photovoltaic power generation system are premised, and we grasped the energy consumption of main 13 fisheries cities. As a result, it was found that CGS can be introduced in many fisheries cities, and electric power can be supplied to important facilities in the area in disaster, and the amount of electricity supply was quantitatively obtained. Therefore, this system is found to be effective, for continuous energy supply in disaster.</p><p></p>
