Through a project titled Monitoring and Modeling Tree Growth, Longevity and Performance, Dr. Yekang Ko states she, “will examine the effects of shade trees on building energy performance in Sacramento, CA.”

According to Ko, the prime sponsor of the study is the United States Forest Service.

“Using field surveys and remote sensing technologies,” Ko said she will “conduct time series analysis to document changes in tree survival, growth, and energy performance for a sample of Sacramento shade trees planted by Sacramento Municipal Utility District (SMUD) around 254 residences from 1991-1993.”

She goes on to say, “This database will be used with the building energy model to calculate effects of each Sacramento Shade Program tree on respective building energy performance over the 20-year period. The long-term effectiveness of different species and locations will be assessed.”

Ko is a professor in the City and Regional Planning Program in the School of Urban and Public Affairs at The University of Texas at Arlington.
