Shade Tree Effects on Campus Energy Use: An Ecosystem Services Analysis.

Building energy use in the Phoenix metropolitan area is greatly impacted by extreme radiant heat due to the urban heat island effect and limited green space. Urban trees provide a number of environmental and economic benefits, including a reduction in energy use for heating and cooling of buildings. Students at Mesa Community College have worked with the campus arboretum to collect measurements of the height and diameter at breast height (DBH) of campus trees for use in the analysis of campus sustainability. The authors contributed to this data set using standard field measurement tools and methods. In this study, the tree data were used to estimate the impact of tree shade on building energy use. We used ArcGIS to calculate the distance and direction from 470 trees to the nearest 44 campus buildings, for a maximum of three vectors per tree. We then used the open-source software package iTree Eco to model the interactions between trees and buildings. We will present the impact of tree shade on building energy use (MBTU and Mwh), effects on carbon emitted from energy generation, and the economic value associated with these changes.
