Phoenix Regional Heat and Air Quality Knowledge Repository
This repository houses peer-reviewed literature, data sets, reports, and other materials generated by researchers, practitioners, and other regional stakeholders that may be informative for local and regional efforts mitigating the adverse impacts of heat. The collection is intended to serve as a resource for anyone looking for information on top research findings, reports, or initiatives related to heat and air quality. This includes community, local, state, and regional partners and other interested parties contributing to heat and air quality planning, preparedness, and response activities.
More Information: The Phoenix Regional Heat and Air Quality Knowledge Repository is product of the Healthy Urban Environments (HUE) initiative in partnership with the Urban Climate Research Center.

While previous studies have shown that urban heat islands (UHI) tend to increase residential water use, they have not yet analyzed the feedbacks among vegetation intensity, diurnal temperature variation, water use, and characteristics of the built environment. This study examines these feedback relationships with the help of a path model applied to spatially disaggregated data from Phoenix, Arizona. The empirical evidence from the observations in Phoenix suggests the following: (1) impervious surfaces contribute to increased residential water use by exacerbating UHI; (2) larger lots containing pools and mesic vegetation increase water demand by reducing diurnal temperature difference; and (3) smart design of urban environments needs to go beyond simplistic water body- and vegetation-based solutions for mitigating uncomfortably high temperatures and consider interactions between surface materials, land use, UHI, and water use.
