Waterfront redevelopment methodology for optimal energy demand and solar energy production: Shinagawa river side in Tokyo Younghun C, Kobashi T, Yamagata Y

Abstract

Designing waterfront redevelopment generally focuses on amenity, hobby and beauty, resulting in various types of building and block shapes. However, increasing climate change impacts necessitates these buildings to be sustainable, resilient, and zero CO2 emissions. Here, we investigate how building morphology affects energy consumption and PV generation in the context of Shinagawa, Tokyo at waterfront for possible redevelopments. For our analyses, we utilized ‘Rhinoceros 3D’ and its plugin ‘Grasshopper’, which is a commonly used architecture program applicable to building energy analysis. It is found that among considered scenarios high-rise buildings had the least energy demand and CO2 emission, emphasizing that building morphology is one of the critical factors, leading to low CO2 emission buildings.
