盛夏来临，海南城市如何消暑纳凉?

Core Concept - The construction of "cool cities" in Hainan aims to mitigate the effects of high temperatures and improve urban livability through ecological and architectural strategies [1][6]. Group 1: Urban Cooling Strategies - Hainan is implementing "cool city" pilot projects in cities like Haikou and Sanya, focusing on ecological spatial layout and building forms to explore urban cooling strategies [1][6]. - The province has established an expert group to address urban heat island effects by optimizing cold source locations and creating ventilation corridors [2][6]. - The design of "cool city" street blocks includes various applications such as cool residential communities and green transportation, enhancing urban comfort and sustainability [3][4]. Group 2: Architectural Innovations - The construction of public and commercial street blocks incorporates design principles that promote airflow and reduce heat retention, such as covered walkways and shaded areas [4]. - The use of green building materials and energy-efficient designs is emphasized, with 90% of new residential buildings in Hainan being green buildings by 2024 [5]. - The Hainan Energy Trading Building features outdoor gardens and a double-layer façade that reduces heat by 62.4%, showcasing innovative architectural solutions [5]. Group 3: Environmental and Policy Support - Hainan is integrating low-carbon strategies into the "cool city" initiative, promoting electric vehicles and achieving a 17.7% increase in new energy vehicle adoption in 2024 [5]. - The province is developing replicable demonstration projects that are quick to implement and effective, aiming to enhance urban livability across Hainan [6].
