Mitigating urban heat island and enhancing indoor thermal comfort using terrace garden

Urban Farm DB summary

A study conducted in Chennai, India, from April to June 2023, assessed temperature dynamics on a building's terrace by comparing a well-maintained garden area with an exposed region using temperature and humidity sensors. Findings indicated a significant reduction in internal room temperatures in areas with rooftop gardens, ranging from 4 to 11 °C, compared to rooms with fully exposed roof configurations. Simulation studies suggested that optimizing soil beds and plant density could yield an additional 3-4 °C reduction, resulting in an overall difference of up to 14-15 °C.
