    Hanoi City, Vietnam, presented the Hanoi Master Plan 2030 in 2011 to cope with rapid population growth and urbanisation. The main objective of this two-part study was to investigate the impacts of land use changes brought by the master plan on urban heat islands in Hanoi by 2030. This paper analyses the contributions of land use changes and global warming to the future increase in urban temperatures in Hanoi by the 2030s. Firstly, numerical simulations using Weather Research and Forecasting (WRF) were conducted for the present land use as well as the land use condition of the master plan under the same weather conditions to detect only the impact of land use changes. Secondly, WRF simulations were conducted for the land use condition of the master plan under the influence of global warming in the 2030s utilising the climate data projected by a Global Climate Model (GCM), Model for Interdisciplinary Research on Climate Version 5 (MIROC5), via a direct dynamical downscaling method. In the 2030s, the average air temperature increase in existing urban areas was projected to be up to 2.1 °C, of which up to 1.5 and 0.6 °C are attributable to global warming and land use changes, respectively.

    In this study, future projections of the thermal environment in the urban districts in Vinh city, Vietnam were performed by a regional atmospheric model, the Weather Research and Forecasting (WRF) model, combined with a pseudo global warming method. The target period was a month of June (hottest month) in the 2030s. A city master plan for the city which targets the year of 2030 with a population of 900,000 and covers an area of approximately 250 km2 was introduced in the future projections, and the impact of the introduction of the proposed plan on the future thermal environment (air temperature and heat stress index) in the urban districts was assessed. Moreover, two modified city master plans by changing the arrangement (northern or southern concentration) of the new urban districts were introduced, and the effects of the modifications on the future thermal environment in the urban districts were also investigated.

    In this study, we focused on natural ventilation in a model house and its effects on the indoor airflow and thermal environments and human thermophysiological responses. Natural ventilation is one of the passive energy saving techniques to achieve low-energy and zero-energy houses. However, it is not always useful because of inappropriate (too low or too fast) airflow or high inflow temperature which makes people feel discomfort. The aim of the present and future studies is to quantitatively investigate the maximum availability of natural ventilation from the viewpoints of indoor airflow and thermal environments and human thermophysiological responses using a coupled analysis of computational fluid dynamics (CFD) model and human thermal model. We tested twelve cases by giving different conditions of the incoming flow (Temporal velocity pattern: 0.0-2.0 m/s, 0.8-1.2 m/s, and 1.0 m/s (constant) with 20° inflow angle; Temperature: 28 °C, 30 °C, 32 °C, and 34 °C) for natural ventilation in a model house. In the cases with the same inflow temperature, instantaneous skin temperature and heat losses of a human body change according to the inflow velocity patterns; however, their time-averaged values are almost the same because the time-averaged inflow velocities in the three velocity patterns are equal (1.0 m/s). Finally, the maximum availability of the natural ventilation is quantitatively discussed by adopting a finding from a subjective experiment under natural ventilation in a model house conducted by Saito et al. (2014). The subjective experiment indicates that the skin temperature (averaged over selected certain segments) without feeling discomfort is 34.5 °C or less. Judging from the experimental finding, the inflow temperature for the natural ventilation targeted in this study can be allowed up to 32.6 °C.

    The generation of appropriate velocity fluctuations at the inflow boundary (inflow turbulence) for large eddy simulation (LES) is a critical and challenging issue, particularly when coupling mesoscale/regional meteorological models and engineering LES models. The authors have previously tested an artificial generation method of inflow turbulence based on the Cholesky decomposition of the Reynolds stresses in the LES analysis of a plane boundary layer flow. However, the well-generated inflow turbulence was rapidly and unphysically attenuated when it flowed downstream. We concluded that this was mainly caused by the dissatisfaction of the governing equations, i.e., continuity and momentum equations. In this study, an approach to imposing the continuity condition on the artificially generated inflow turbulence was proposed and, in the LES analysis of a plane boundary layer flow, its effects were examined by comparing the results with those without the continuity condition and using periodic inlet-outlet boundary condition. As a result, the attenuation of the turbulent kinetic energy near the inflow boundary was slightly improved by imposing the continuity condition on the artificially generated inflow turbulence.

    The possibility of a huge earthquake and the following disasters, such as tsunami and ground liquefaction, in the near future has been pointed out in the third largest metropolitan area (Nagoya metropolitan area) in Japan. In the region including the Nagoya metropolitan area, a huge earthquake of magnitude 8 class has occurred every 100-150 years. The last huge earthquake in the region happened in 1944. Therefore, the viewpoint of disaster mitigation/prevention against an expected huge earthquake is crucial for future urban planning in the Nagoya metropolitan area. On the other hand, the population in the Nagoya metropolitan area is expected to decrease in the future. Such a decrease in population usually leads to a reduction of the urban area. In this study, three disaster mitigation/prevention urban structure models were designed for future urban planning of the 2050s (the target period in which about 100 years will have passed since the last huge earthquake) in the Nagoya metropolitan area considering a reduction in the urban area according to a projected decrease in population. Subsequently, the impacts of the introduction of the three disaster mitigation/prevention models, i.e., (1) a tsunami damage mitigation/prevention model, (2) a strong motion damage mitigation/prevention model, and (3) a ground liquefaction damage mitigation/prevention model, on the future (the 2050s) thermal environment were quantitatively investigated using a regional atmospheric model, the Weather Research and Forecasting (WRF) model. Moreover, an urban structure model that combined the three disaster mitigation/prevention models was constructed, and the effect of the combined model on the future thermal environment was also evaluated.

    Extreme high temperature events occur frequently in Nagoya city of Japan, and have been of great concern recently because they bring risks to the energy supply, public health, and more. In this study, changes in electricity demand and thermal comfort in Nagoya city with future climate change were projected by WRF-CM-BEM which coupled a multi-layer urban canopy model CM, and a building energy model BEM in a regional climate model WRF. The results showed that summer time daily mean electric demand and human thermal comfort (SET*) in Nagoya city were projected to increase by about +4.9 W/floor m2 and 2.8 ºC in the 2070s, respectively. However, sensitivity experiments indicated that urban greening adaptation strategy have the potential to reduce by 33% and 10% of above projected values, respectively. In comparison with urban greening, anthropogenic heat reduction strategy was estimated to have smaller influence to improve future electric demand and human thermal comfort in Nagoya city.

    In this study, a coupled analysis of computational fluid dynamics (CFD) and heating, ventilation, and air-conditioning (HVAC) system simulations was applied to a multi-split air-conditioning system in the operation phase during a power-saving period in summer. Two different forced operation schemes for the indoor units, i.e., a regular rotation control and a lowest reference temperature control for switching cooling and fan modes, were designed, and the effects of the two operation schemes on the indoor thermal environment were investigated. When the reference temperature points for the indoor units were located at a height of the occupied zone, the lowest reference temperature control was better than the regular rotation control from the viewpoint of creating a more uniform thermal environment in the occupied zone.

    In this study, future projections of the thermal and wind environments in June (hottest month) of the 2030s in Vinh city were performed by introducing a city master plan proposed by Nikken Sekkei Civil Engineering Ltd. The projections were carried out using a regional atmospheric model, the Weather Research and Forecasting (WRF) model (Skamarock et al. 2008), combined with the pseudo global warming method proposed by Kimura and Kitoh (2007). By comparing with the present land use case, the effects of introducing the city master plan on the future thermal and wind environments in Vinh city were quantitatively investigated. Additional cases with the change in urban structure (northern or southern concentration of the new urban districts) were conducted, and the effects of the modifications of the city master plan on the future thermal and wind environments were also studied.

    In this study, the effects of introducing vertical ventilation paths on the thermal and wind environments in city blocks were investigated using computational fluid dynamics (CFD) simulations. In particular, the effects of two vertical geometric parameters of the buildings, i.e., the average height of the buildings and the standard deviation of the building heights, in the windward region on the pedestrian thermal and wind environments in both the windward and leeward regions were quantitatively evaluated. In the windward region, the standard deviation of the building heights in the region was more effective for improving the pedestrian thermal environment. On the other hand, the average height of the buildings in the windward region affected the pedestrian thermal environment in the leeward region more than did the standard deviation of the building heights in the windward region. Furthermore, the correlations between the space-averaged air temperature and wind velocity at the pedestrian level were different in the windward and leeward regions. In the windward region, the correlation became negative, while a positive correlation was observed in the leeward region.

    In this study, future projections of the thermal environment in the summer of the 2050s in the Nagoya metropolitan area were carried out by using a regional atmospheric model, Weather Research and Forecasting (WRF). Three disaster-mitigation/prevention type urban structure models were introduced for the future projections. A tsunami-damage mitigation/prevention model, a strong-motion damage mitigation/prevention model, and a liquefaction-damage mitigation/prevention model were designed as the future urban structure models considering a reduction of the urban area according to a projected decrease in population. By comparing with the results obtained from the present land-use model, their impacts on the future thermal environment were quantitatively investigated.

Here, three urban planning/structure models (centralized and decentralized models, and a plan to avoid tsunami damage) were introduced. Furthermore, for the future urban planning/structure models, we considered the reduction of urban areas due to the predicted decrease in population, and investigated the change of the thermal environment with the reduction of urban areas.

    Recently, vertical ventilation paths are receiving considerable attention as promising countermeasures to hot environment in summer. Vertical ventilation paths channel cooler upper winds into city blocks by using vertical turbulent diffusion enhanced by the vertical heterogeneity of building shapes. However, their effectiveness is limited because the temperature of the flow gradually becomes higher and the momentum of the flow for vertical ventilation paths gradually decreases. In this study, we investigated the effects of introducing vertical ventilation paths in city blocks by using CFD simulations. We examined the effects of the vertical heterogeneity of building shapes in the windward region on the thermal and wind environments in both the windward and leeward regions based on a heat balance analysis, space-averaged temperatures, and a proposed evaluation method using the turbulent kinetic energy profile.

    In order to apply Computational Fluid Dynamics (CFD) techniques to estimate pollutant dispersion in urban areas, it is important to assess the performance of numerical models used to estimate these phenomena. Recently, the MUST (Mock Urban Setting Test) has often been adopted as a test case for evaluating numerical models for micro-scale urban meteorology. This paper presents the results of model evaluation exercises carried out using MUST based on the Architectural Institute of Japan (AIJ) experience. The results of model evaluation exercises conducted by AIJ are broadly consistent with the results obtained by the COST group. However, the variety of results by each computation can be minimized by setting standard computational conditions. All computations including both RANS and LES show good agreement with wind experiment data. In general, LES cases show comparable accuracy to RANS in predicting U and W. However, LES shows better agreement than RANS in TKE and concentration.

    Tajimi, a city located in Gifu Prefecture, experienced the record high temperature in Japan (40.9 °C) on August 16, 2007. The problems associated with high temperatures in summer are very serious in the city. It is considered that various factors such as topographic basin effect and heat island around Nagoya affect high temperatures in Tajimi. However, each contribution of those factors is not clear enough. In this study, a sensitivity analysis of the factors in high temperatures in Tajimi for recent five years was conducted by using a regional atmospheric model, WRF (Weather Research and Forecasting). Here, we investigated the effects of urban heat islands in Tajimi and Nagoya and topographical effects on the thermal environment in Tajimi.

    For merging of mesoscale/regional meteorological models and engineering large-eddy simulation (LES) models seamlessly, to generate appropriate velocity fluctuations at the inflow boundary (inflow turbulence) for engineering LES models is a very essential issue. In this study, we introduced three artificial generation methods of inflow turbulence based on the Cholesky decomposition of Reynolds stresses in the LES analysis of a plane boundary layer flow, and assessed the performance of those methods by comparing their results with those from a LES computation with periodic inlet-outlet conditions. In particular, we investigated the effects of space and/or time correlations of the generated inflow turbulence on the downstream turbulence characteristics.

    Future projections of thermal and wind environments in the summers of the 2030s, the 2050s, the 2070s, and the 2090s in the Nagoya metropolitan area were carried out by using a regional atmospheric model, WRF. In the future projections, the pseudo-global warming method proposed by Kimura et al. (2007) was introduced to consider the effects of global warming as background data. Here, we used IPCC SRES A2 and B1 scenarios to represent the effects of future global warming. We also performed a present prediction (2010) and compared the differences between the present and future projections. Furthermore, the differences between the results obtained with IPCC SRES A2 and B1 scenarios were investigated.

    A coupled analysis of CFD and HVAC system simulations was carried out to assess the mixing energy loss in an air-conditioned office room where heating and cooling operate in the perimeter and interior zones simultaneously. To evaluate the mixing energy loss, we conducted two simulations; one was the case with the airflow mixing between the perimeter and interior zones and the other was the case without the airflow mixing. By comparing the required coil loads between the cases with and without the airflow mixing, the mixing energy loss was estimated. The accuracy of the coupled analysis was assessed by comparing the results with those from an experiment by Ito (1988).

    The current status and remaining issues of coupling CWE models with mesoscale meteorological models (MMM) are reviewed from the view point of computational wind engineers. By way of three examples to demonstrate the typical application areas where the coupling approaches are needed, the governing equations considered, and the difficulties to couple the models despite the different spatial and temporal scales are described. Next, recent attempts of single-model up-scaling of CWE models to meteorological scale wind flow and thermal environment are shown. The need to upgrade existing CWE models for appropriate up-scaling and the issues that require to be solved by the collaboration with meteorologists are pointed out. Finally, the recent achievements attained by other researchers are reviewed and the future directions of CWE studies are discussed. Emphasis is placed on coupling LES with MMM.

    A numerical investigation of present (2006) and future (the 2070s) thermal environments in summer in the Nagoya Metropolitan Area was conducted using the Weather Research and Forecasting (WRF) model. In the future projection, a pseudo-global warming method was incorporated to consider the effects of global warming as background data. Based on the simulation results, analyses of heat balance structures at several locations were also carried out using an urban heat balance model. The heat balance structures between the present and future projections were compared, and the differences in the heat transfer mechanisms between the present and future statuses were investigated.

    The current status and remaining issues of coupling CWE models with mesoscale meteorological models (MMM) are reviewed from the view point of computational wind engineers. By way of three examples to demonstrate the typical application areas where the coupling approaches are needed, the governing equations considered, and the difficulties to couple the models despite the different spatial and temporal scales are described. Next, recent attempts of single-model up-scaling of CWE models to meteorological scale wind flow and thermal environment are shown. The need to upgrade existing CWE models for appropriate up-scaling and the issues that require to be solved by the collaboration with meteorologists are pointed out. Finally, the recent achievements attained by other researchers are reviewed and the future directions of CWE studies are discussed. Emphasis is placed on coupling LES with MMM.

    The activity of a taskforce to make a guideline for a Diffusion Model based on Computational Fluid Dynamics (DiMCFD) to use for the atmospheric environmental impact assessment is reported. The taskforce was established in 2006 by the Japan Society for Atmospheric Environment. The applicability of DiMCFD to environmental impact assessment may be very large; however, the results sometimes diverge if conditions are not specified adequately. In the first stage, we limited our efforts to the problems of short distance dispersion in urban areas under neutral stability. The consensuses and some results are shown.

    A WRF-LES computation was carried out for the analysis of a wind environment in the summer in the Nagoya Metropolitan Area, which is located in the central part of Japan. We also performed a single WRF computation with no LES capability and compared the results between the WRF-LES and single WRF computations. The WRF-LES computation predicted a larger magnitude of wind velocity than the single WRF computation. In addition, we are now conducting other WRF-LES computations using the "LES-within-LES" method proposed by Moeng et al. (2007) and using our homemade LES software with an artificial generation method of inflow turbulence.

    本研究では、愛知県名古屋市内の木造密集市街地を対象とし、新たに開発する「飛び火延焼モデル」を組み込んだCFDベースのシミュレーションモデルによる「火災延焼予測」を行う。飛び火延焼モデルは、飛び火の建物内部侵入の着火過程を確率モデルとして取り扱い、建物内部延焼に関して本研究で行う火災実験や既往の火災実験の結果を基にモデル化して開発する。火災延焼予測では、様々な気象状況を想定し、火元位置や火の粉の発生条件を系統的に変化させたケーススタディを実施する。さらに、名古屋市消防局と協働し、火災延焼予測結果に基づく必要消火水量の推定を行い、大規模火災に対応可能な「消防水利更新計画」を検討・提案する。
    2021年度は、2020年度に開発したCFDベースの火災延焼シミュレーションモデルに組み込む「飛び火延焼モデル」の改良を進めつつ、同シミュレーションモデルによる木造密集市街地を想定した市街地モデルを対象とした火災延焼シミュレーションのケーススタディを実施した。
    本研究で開発した「飛び火延焼モデル」では、窓(開口部)を介して飛散する火の粉が建物内部へ侵入するモデルを構築しているが、その開口部面積は、本研究の対象地としている名古屋市の特定地区の木造住宅調査結果に基づいて決定している。実施したケーススタディでは特に、開口部の配置の違いや、建物内部への火の粉侵入後の可燃物への必要着火個数および堆積確率の違いが市街地モデル全体の火災延焼範囲に及ぼす影響を定量的に評価した。さらに、火災延焼範囲の時間変化についても比較した。なお、本ケーススタディでは、市街地内の個々の建物の違いは検討外とした(市街地内の建物モデルは同一)。
    本ケーススタディを通じて、開口部の配置(主流方向に対する開口部の向き)の違いによって市街地モデル全体の火災延焼範囲が大きく異なること(例えば、火災発生原因建物全焼から1200秒後の時点で、開口部が主流方向に対して垂直に位置する場合は主流方向に対して平行に位置する場合よりも火災延焼範囲が約3倍拡大)、建物内部への火の粉侵入後の可燃物への堆積確率よりも着火個数の設定の方が火災延焼範囲に及ぼす影響が大きいこと、などを明らかにした。
    当初の計画通りの研究が実施できている。
    本研究は3年計画であり、2020年度、2021年度の2年間は当初の計画通りの研究が順調に進んでいる。次年度は最終年度となるが、当初の計画通りの研究を進めていきたい。

    本研究では、名古屋・福岡都市圏を対象とし、流域レジリエンスに向けた雨水浸透・貯留・流出抑制型緑地管理システムの構築を目的とする。具体的には、(1)流域―緑地類型を行い、(2)緑地類型別の三次元構造と管理レベルの相関を分析し、(3)緑地類型別・管理レベルごとの雨水浸透・貯留・流出抑制機能を評価し(4)将来の流域レジリエンスに向けた緑地管理システムを構築する。
    名古屋・福岡都市圏において、緑地管理に関する統計資料・大規模アンケート・ヒアリング調査を活用し、標準的な管理主体1人当たりの「管理作業量=年間で対象とする緑地に対し投下可能な管理作業時間 (h)」の算出を行った。また、ヒアリング、現地実測調査により、機械(例:大型トラクター等)や先進技術(例:ロボット草刈り機等)による管理作業量の削減効果についても算出を行った。次に、緑地類型別ごとの雨水浸透・貯留・流出抑制機能の実測値を反映した氾濫シミュレーションを行った。具体的には、内外水複合氾濫モデルのベースモデルとして、MVH Soft社が開発した「InfoWorks ICM」を採用し、名古屋都市圏木曽川流域における津島市を対象とし、観測された降雨を基に作成される確率降雨を入力データとして、樹幹遮断や地表面上のくぼ地貯留による初期喪失分を除いた後、地表面流出量計算過程で、地中へ浸透させる量(雨水浸透量)と地表面上に流出し下水管に流れ込む量(地表面流出量)の算定を行った。その算定に当たり、緑地による浸透面に対して、先に実測調査により明らかとした最終浸透能を用いたホートン式により雨水浸透量を計算し、浸透できない余剰降雨を地表面流出量として算定する。さらに、これにより得られたシミュレーション結果と、過去の氾濫実績(九州北部豪雨・東海豪雨)との比較によるシミュレーションの精度検証を行った。また、福岡都市圏・那珂川流域を対象に、RRIモデルを活用して、マクロスケールにおける雨水浸透・流出シミュレーションを試験的に実施した。
    指標化を行った緑地類型別・管理レベルごとに、雨水浸透・貯留・流出抑制機能の大規模実測評価を行う必要があるが、実測装置の測定条件の整理に時間を必要とし、本年度は試験的に、散水式雨水浸透装置のグラウンドにおける実測、ミニディスクインフィルトロメーターにおよる耕作放棄地における実測にとどまっている。次年度、大規模実測を行うことで、緑地の管理状況別の測定値の集積を行う必要がある。具体的には、緑地類型別・管理レベルごとに調査対象地を選定し、実測装置の設置・実測を行い、異なる降雨強度に対する雨水浸透・貯留・流出抑制機能の網羅的データを整備する必要がある。また、コロナ禍が続き、福岡都市圏・久留米市内、また名古屋都市圏、櫛田川流域における現地ヒアリング調査を何度か断念せざるを得ない状況が出ており、現地に入れる回数が減少した。得られたデータについては、オンラインアンケートと合わせて整備が進み、2022年度にかけて論文投稿を行っていく。
    2022年度には、整備した緑地類型別・管理レベルごとに、雨水浸透・貯留・流出抑制機能の大規模実測評価を行う。具体的には、緑地類型別・管理レベルごとに調査対象地を選定し、実測装置の設置・実測を行い、異なる降雨強度に対する雨水浸透・貯留・流出抑制機能の網羅的データを整備する。
    さらに、コーホート分析を用いて2040年と2050年の人口予測を行い、男女別・年齢構成別に流域単位の人口データを整備する。次に、標準的な管理主体1人当たりの「管理作業量=年間で対象とする緑地に対し投下可能な管理作業時間 (h)」を活用し、将来人口予測と掛け合わせることにより、将来の緑地類型別に投下可能な管理作業量を算出し、緑地類型別・管理レベルの予測評価を行う。さらに、氾濫シミュレーションモデルを活用し、将来の流域の豪雨時の脆弱性評価を行う。この評価結果に対し、将来管理コストが縮減する中で、管理コストの効果的・適正な配分を行うことで、緑地の有する雨水浸透・貯留・流出抑制機能を最大限活用するための定量的・統合的な緑地管理システムを構築する。具体的には、先端的技術や機械による管理コストの削減や、より雨水浸透・貯留・流出抑制機能の費用対効果の高い緑地管理手法の導入、氾濫危険度が高く優先的緑地保全が必要な地域の同定等を統合評価する緑地管理システムを構築する。以上の緑地管理システムで得られた結果について、名古屋・福岡都市圏の対象流域において実際の政策へ反映されるように、関連主体や自治体に対し、シンポジウムの開催等を通じて成果発信・意見交換を行い、積極的に働きかける。また、本研究成果は英文書籍として取りまとめて出版し、流域レジリエンスに向けた緑地保全システムのモデルケースとして、国際的に広く発信し、さらなる議論を展開していく。

    近年、建築分野では世界的にZEBが指向されており、全ての新築建物のZEB化は国の目標でもある。ZEBの設計ではシミュレーションが活用されるが、その際に用いる気象データはどのような特徴を持つものが適しているか検討されていない。建物の設計用の気象データとしては、世界的に標準年が使用されているが、ZEBの計画に際しては、平均的な気象条件ではなく、むしろ過酷な気象条件での評価が重要になると考えられる。本研究では、真のZEB社会の実現を目指して、ZEBやZEHの評価に適した現在と近未来の設計用苛酷気象データの作成方法を検討し、国内および東南アジアの年間気象データを整理・公開することを目標とする。
    ZEB(ネットゼロエネルギービルディング)のエネルギーシミュレーションに用いる1分値気象データを整理した。2011~2020年の10年間のデータ整理を目的として、1分値データに含まれる欠測を補充する方法について検討した。今年度はホットデック法の改良とニューラルネットワークによる機械学習について検討した。その結果、機械学習では要素によっては誤差が大きくなる現象がみられたので、1分値の欠測補充にはホットデック法を用いることとした。
    2010年の1分値気象データとEA気象データを用いて、札幌,東京,鹿児島のエネルギーシミュレーションを行い、どのような気象条件の時に発電量と消費量の差が大きくなるか考察した。得られた知見を元に、10年間の気象データから月毎に過酷な月を選定し、過酷気象データを作成した。その際に各月毎に最も過酷な年をつなぎ合わせると厳しい条件になりすぎることが明らかになった。
    将来の過酷気象データについては、名古屋都市圏を対象として、現状および将来2050年代の過酷気象データの作成を行った。ここでは過酷気温に着目して過酷な年を選定した。現状および将来2050年代の過酷気象データの応用事例として、建物熱負荷計算や空調エネルギー消費量計算を行い、標準年気象データを用いた場合と比較した。
    インドネシアで全天日射量と天空日射量,方位別鉛直面日射量と大気放射量を長期観測している。得られたデータを元に、分単位の日射の直散分離,斜面日射量の合成方法について検討した。また大気放射量から夜間放射量を算出し、冷却ポテンシャルがどの程度あるか整理した。このほか、観測したデータを元に、1年間のEPWフォーマットデータを作成した。これによりEnergyPlusなど建物のエネルギーシミュレーションの入力データとして利用できることを確認した。
    本研究ではZEBのエネルギー収支をより詳細に検討するため、シミュレーションに用いる気象データとして1分値や5分値の利用を条件とした。そのためにまず1分値気象データを整理する必要があり、データに含まれる欠測の補充方法について検討した。ホットデック法とニューラルネットワークによる機械学習を適用した結果、ホットデック法による補間が有効であることを明らかした。
    ZEBのモデル建物を対象として、1分値気象データを用いて日ごとのエネルギー収支を考察し、札幌、東京、鹿児島について、エネルギー収支が大きく崩れる条件を整理した。これらの知見を元に、10年間の気象データから月毎に過酷な月を選定し、過酷気象データを作成した。その際に各月毎に最も過酷な年をつなぎ合わせると厳しい条件になりすぎるので、2番目の月を選定する方法を提案した。
    将来の過酷気象データについては、2050年代(2050~2059年)を対象とした過酷気象データは、地球スケールから大陸・国スケール、都市スケールに至る気候・気象予測を一気通貫に行う温暖化ダウンスケーリングシミュレーションの結果を用いて作成した。各月に対して対象期間の中で過酷気温が多頻度で含まれる年(過酷年)を抽出し、その月間データをつなぎ合わせて作成した。
    日射の直散分離と斜面日射量の合成手法については、インドネシアで日射量を観測しており、2年以上のデータを収集できた。得られたデータを元に、日射の直散分離,斜面日射量の合成方法について、これまでに提案されている手法が適用できるか検討した。その結果、1時間積算値については概ね良く一致したが、瞬時値についてはばらつきが大きく改良が必要であることを明らかにした。またインドネシアで観測した大気放射量から夜間放射量を算出し、冷却ポテンシャルがどの程度あるか整理した。
    1分値気象データの欠測補充については、改良したホットデック法で国内の日射観測地点について2011~2020年の1分値気象データを整備する。
    過酷気象に関しては、BestとEnergyPlusによるエネルギーシミュレーションを行い、気象データとの関係性を整理し、過酷気象年の選定方法を提案する。これまで検討した方法では過酷度が強すぎてZEBが成立しない条件になったので、選定方法を改良して適切な条件を提案する。そして過酷気象データを用いたシミュレーション結果が、統計的にどの程度の危険率に相当するか明確にする。
    将来の過酷気象データについては、地球スケールから大陸・国スケール、都市スケールに至る気候・気象予測を一気通貫に行う温暖化ダウンスケーリングシミュレーション(直接ダウンスケーリングシミュレーション)の結果を用いて、各月に対して対象期間の中で過酷気温が多頻度で含まれる年(過酷年)を抽出し、その月間データをつなぎ合わせて作成する方法をこれまでに提案した。今後、気温以外の気象要素も加味した過酷気象データの作成方法を検討する。また現状および将来2050年代の過酷気象データの応用事例として、建物熱負荷計算や空調エネルギー消費量計算を行い、標準年気象データを用いた場合と比較し過酷気象データの有用性を明らかにする。
    熱帯地域での設計用の気象データ(TMY)については、これまでにインドネシアで観測した日射量と大気放射量のデータを用いて、日射の直散分離と斜面日射量の合成方法,および大気放射量の推定方法を提案する。また気象衛星の画像データを用いた、時別日射量と大気放射量の推定方法を提案し、日射量を観測していない気象観測所のTYMの作成方法を可能にする。また代表都市の過去10年間の気象データを収集し、TMYと過酷気象データを作成する。
