P2 1* 2* 3* P4 The BEI (Building Energy Index) measures the energy efficiency of buildings. Smaller values indicate higher energy savings.Green electricity: Net renewable electric power supplied through the combination of power from all sources, centered on thermal power supplied by TEPCO Ener-gy Partner, Incorporated, and feed-in tariff (FIT) non-fossil certificated solar, wind, hydro and other renewable power sources compliant with the FIT system.FIT Non-Fossil Certificates originating from solar power generators in Miyagi and Aomori prefectures were allocated for the electricity consumed at the Nikken Sekkei Tokyo Building from November through December 2022.City gas made from liquefied natural gas (carbon neutral LNG), which offsets the greenhouse gases generated in the process from extraction to combustion of the natural gas with CO2 credits (carbon offset) from environmental conservation projects and so is deemed to not generate CO2 on a global scale even when combust-ed.Showa Gakuin Elementary School West Wing (Photo by Gankosha (Harunori Noda ))DaiyaGate Ikebukuro (Photo by SEIBU REALTY SOLUTIONS Inc.)Supercomputer “Fugaku” (Provided by RIKEN)Shinjuku Sumitomo Building (Photo by SS.inc)
