Abstract/Contents:"Many cities, especially those in arid and semiarid environments, are warming due to urban heat island (UHI) effects, induced by changes in land cover and built forms. Those local climate variations lead to a higher demand for air conditioning in the summer and increased human discomfort. This study investigated the impact of urban form and landscaping on the microclimate in Phoenix, Arizona. We used the three dimensional microclimate model ENVI-met® to simulate near-ground air temperatures for typical neighborhoods in Phoenix. First, ENVI-met® was calibrated using the CAP LTER North Desert Village (NDV) landscape experiment at Arizona State University's Polytechnic Campus. This site is an ideal test bed to determine the model's input paramters since it is a controlled environment recreating four prevailing residential landscape types in the Phoenix metropolitan area (mesic, oasis, xeric, native). After calibration, we designed urban form and landscaping scenarios that represent a realistic cross-section of typical residential neighborhoods in Phoenix. To find the most effective urban form and design strategies to ameliorate temperatures during the summer months and, consequently, to reduce residential energy use, simulation results were analyzed in terms of mid-afternoon air temperature distributions, ventilation, and their relationship to parameters such as sky-view factor and related short-wave radiation. Mesic landscapes provided the expected cooling by several °C during the day compared to oasis, xeric, and native ones. However, the building characteristics (height, orientation and distribution) further determined within-design spatial differences in cooling, strongly related to the solar radiation and local shading patterns."
