Irrigation of green spaces in cities helps to reduce thermal stress and building energy consumption in hot seasons, but requires an intricate balance between energy and water resource usage. In this study, a cutting-edge urban canopy model is applied to assess the impact of a variety of controlled irrigation schemes for Phoenix. Among all investigated schemes, the soil-temperature-controlled irrigation is the most efficient in reducing the annual building energy consumption and the total cost. The total annual saving depends on the controlling soil temperature for irrigation activation, and can be up to about $1.19 m−2 wall area as compared to the current irrigation practice.
