全球首个超阶零碳大楼启用

Core Insights - The world's first ultra-zero carbon building has been officially launched in Qingdao, Shandong, featuring a collaborative operation of "photovoltaics + energy storage + electric vehicle charging and discharging" to create a virtual power plant at the park level, achieving 100% green energy replacement [1][2] Group 1: Project Overview - The project commenced construction in May 2023 and is expected to be completed by March 2025, covering an area of approximately 43,000 square meters with a total height of 117 meters [1] - The building integrates multiple innovative achievements from Trina Solar Group, focusing on the fusion of "charging network, microgrid, and energy storage network" [1] Group 2: Energy Efficiency and Environmental Impact - The building has a daily electricity consumption of about 6,000 kWh, with its east, west, and south facades featuring building-integrated photovoltaic glass curtain walls, generating direct current electricity to meet approximately 25% of the building's energy needs, resulting in an annual carbon reduction of nearly 500 tons [1] - The building utilizes 14 sets of tiered automotive power battery packs, which complete daily charge and discharge cycles, absorbing surplus photovoltaic power and storing clean electricity at a low cost of 0.22 yuan/kWh during off-peak hours, significantly enhancing grid regulation capabilities [1] Group 3: Economic and Operational Benefits - The ultra-zero carbon building is expected to consume a large amount of green electricity annually, reducing carbon emissions by nearly 2,500 tons, while digitalized operations lower investment costs by 20% to 30%, improve operational efficiency by 30%, and reduce overall energy costs by approximately 30% [2] - The building represents a complete energy ecosystem, achieving self-sufficiency in 100% green electricity and establishing a new model for zero-carbon buildings [2]
