日本語
建築一体型太陽光発電（BIPV）の多目的最適化に、CanESM5のSSP3-7.0将来気候を組み込む計算枠組みを開発。日よけと薄膜窓コーティングの2構成を4都市で比較した。従来のEPWデータはBIPV性能を系統的に過小評価し、2046〜2050年には全都市で性能向上、特にベルリン・シカゴ・ロサンゼルスで顕著だった。2050年には無遮蔽窓はエネルギー収支に悪影響となり、薄膜は80〜90%の高吸収率が最適と示された。
English
This study builds a multi-objective optimization framework for BIPV envelopes using CanESM5 SSP3-7.0 future climate projections, comparing awning shades and thin-film window coatings across Berlin, Los Angeles, Chicago, and Singapore. Conventional EPW datasets systematically under-predict BIPV performance. Under 2046–2050 conditions all cities gain, most in Berlin, Chicago, and Los Angeles, while unshaded windows become detrimental and thin-film coatings favor 80–90% absorptance.

📄 Abstract（原文）
Building-integrated photovoltaics (BIPV) are a promising strategy for enhancing building energy performance and reducing carbon emissions. However, most design optimization studies rely on historical climate datasets that may fail to capture the operating conditions buildings will experience under climate change. This study develops a computational framework for the multi-objective optimization of BIPV envelope systems using future climate projections from the CanESM5 model under the SSP3-7.0 scenario. We analyze two system configurations, awning shades and thin-film window coatings, across four cities with diverse climates (Berlin, Los Angeles, Chicago, Singapore), comparing results from conventional EPW files, NASA 2023 historical data, and 2046–2050 climate scenarios. Optimization integrates electricity generation, thermal loads, and daylighting quality to capture building-level trade-offs. Results show that traditional EPW datasets systematically under-predict BIPV performance, particularly in Berlin and Los Angeles. Under 2046–2050 projected conditions, all four cities exhibit performance gains: substantial in Berlin, Chicago and Los Angeles, and marginal in Singapore, with the largest absolute gains in Los Angeles. By 2050, unshaded windows transition to consistently detrimental for building energy balance. Thin-film coatings achieve optimal outcomes at high absorptance, in the 80–90% range, contrary to current low-absorption design practice. Within the CanESM5 SSP3-7.0 scenario examined, these findings show that projected climate conditions can substantially reshape the modeled performance landscape of BIPV systems, emphasizing the need for forward-looking climate projections in building design optimization and the growing importance of BIPV for climate-adaptive and resilient urban buildings.
