| DESIGN NAME: Yokohama Symphostage PRIMARY FUNCTION: Complex Building INSPIRATION: Taking advantage of the strengths of a consortium involving several business owners, the public facility is a developed sterically space with multiple uses being developed in an organic organizational manner, with each business owner taking charge of the programs in which they excel.The plaza is used for various lively events, including music events hosted by Yokohama City and Yamaha, creating an environment where people naturally gather. UNIQUE PROPERTIES / PROJECT DESCRIPTION: This is a complex with a total floor area of approx. 180,000 m2 and connected to the pedestrian network, an important infrastructure linking central Yokohama and its surrounding areas.Located on a site intersected by two key pedestrian axis which connect the Minato Mirai district to surrounding areas. Historically disconnected, these pedestrian spaces are revitalized and interconnected through a multi-layered plaza and lively public facilities where people can gather during events and disasters. OPERATION / FLOW / INTERACTION: The main circulation paths traverse the first and second floors of the site, with vibrant public facilities concentrated in the lower levels. Adjacent multi-layered plazas are tailored to the characteristics of these facilities, designed to allow indoor activities to blend seamlessly with the outdoors. These spaces aim to amplify and diffuse activities across external areas and other floors. PROJECT DURATION AND LOCATION: Location : Minato Mirai, Yokohama City, Kanagawa, Japan Construction period : April 2021 - March 2024 FITS BEST INTO CATEGORY: Architecture, Building and Structure Design |
PRODUCTION / REALIZATION TECHNOLOGY: The multi-layered plaza was planned using simulations for wind, sunlight, and pedestrian flow to optimize each space for its intended use. The large glass roofs adjust the environment of semi-outdoor spaces.For the office areas, solar simulations led to the exterior wall design to achieve an optimal balance of sunlight for air conditioning and lighting efficiency. Automated control of jalousie windows and blinds further integrates environmental factors into a comfortable working environment. SPECIFICATIONS / TECHNICAL PROPERTIES: Location : Minato Mirai, Yokohama City, Kanagawa, Japan Use : Office,Hotel,Store Construction period : April 2021 - March 2024 Site area : 20,620.58 m2 Building area : 14,723.65 m2 Total floor area : 182,937.70 m2 Number of floors : 1 story below fround,30 floors Maximum Height : West Building:158.633m , East Building: 89.733m Structure : steel construction (part of columns, cft construction)partial TAGS: Architecture, Pedestrian, Plaza, Seascape, Simulation, Sustainability, BELS, ZEB, Obayashi RESEARCH ABSTRACT: The project deployed unique methodologies exclusive to our Technical Research Institute. Wind environment simulations covering the entire area validated the minimal impact on the environment. This confirmed the utility of high-rise terraces, and natural ventilation systems. Additional achievements included evacuation planning through comprehensive safety assessments, acoustic environment simulations for complex geometries, and the creation of organically shaped benches by 3D printing. CHALLENGE: Achieving Cost-Effective Energy Savings and Decarbonization with Advanced Design Methods The project utilized advanced heat load simulations (EcoSimule) to strategically incorporate features such as double-skin curtain walls, solar shading fins, and energy-efficient air conditioning systems selected for their cost-effectiveness. As a result, the project efficiently achieved BELS 5-star, ZEB Ready, and CASBEE Yokohama S-rank certifications.
