A metropolitan area that is significantly warmer than its surrounding rural areas due to material heat storage, anthropogenic heat, and airflow obstruction is called the urban heat island effect. This not only exerts negative impact on human health and comfort, affecting the quality of urban life, but also increases energy consumption and carbon emissions due to air-conditioning usage in response to rising temperatures. To understand and analyze this important issue of sustainable urban development, the BCLab, led by Professor Tzu-ping Lin of NCKU, teamed up with the Tainan City Government in setting up the High Density Street-level Air-temperature Observations Network (HiSAN). The results of the measurement and analysis of 102 residential temperature measurement points was introduced into the regulatory norms for high-temperature and weak-wind potential areas in urban design deliberations. At the same time, the team also worked with the Kaohsiung City Government to further import IoT technology, establish the smart temperature and environment observation network in Kaohsiung (STONK), and upload real-time environmental information to the cloud, which will benefit Kaohsiung's policy on management of land use, three-dimensional greening and allocation of solar panels.
隨著都市的高密度發展，都市中因為材料蓄熱、人工排熱、氣流受阻的因素，造成都市中心區域較郊區高溫的問題，亦即「都市熱島效應」。它不僅危害人體的舒適健康，降低都市生活品質，同時，室內上昇的溫度將造成建築室內空調耗電量增加，加劇城市能源耗用及碳排放。為了理解及分析這個攸關永續城市發展的重要議題，成功大學林子平教授領導的建築與氣候研究室(BCLab)與台南市政府合作，建立｢高密度地面氣溫量測網｣(High Density Street-level Air-temperature observations Network，HiSAN)，將102個人居層溫度測點的量測分析成果導入都市設計審議中對於高溫及弱風速潛勢區的管制規範。同時，也與高雄市政府合作，進一步導入IoT的技術，建立smart temperature and environment observation network in Kaohsiung, STONK)，將即時的環境資料上傳雲端，有助於高雄厝政策在土地利用、立體綠化、光電版較佳配置之管理應用。
