Towards the Next Generation of Green Building for Urban Heat Island Mitigation: Zero UHI Impact Building

This paper addresses the pressing issue of global warming and the urban heat island (UHI) phenomenon in cities, with a focus on the role of buildings. Specifically, the concept of a green building (GB)-based UHIM system is introduced as a means to mitigate UHI effects. Referred to as a 'zero UHI impact building', 'zero-heat building', or 'microclimate neutral building', this system aims to eliminate excessive heat and achieve zero-heat impact on the surrounding environment through thoughtful building design, operation, and innovative techniques aligned with GB goals. 

The article defines the scope of the GB-based UHIM system, explores the interactions between buildings and urban heat fluxes, and identifies factors influencing the application of UHIM techniques to building components. It analyzes the potential benefits of establishing the GB-based UHIM system in terms of mitigating UHI impacts and outlines the implementation pathway. This research provides a theoretical and practical foundation for the adoption of GB-based UHIM systems, representing an important advancement in the building sector's response to rising temperatures.
