  1. Planting Trees to Reduce HeatAn Analysis of NeighborWoods Alan Halter City of Austin Urban Forestry Planning & Development Review

  2. Overview • Large-scale tree planting = public PR • MillionTrees NYC • Million Trees LA • NeighborWoods Program (ATX) • Distributes 3,600 trees/year to residents • Goal: reduce energy consumption and urban heat • Rarely evaluated for effectiveness!

  3. Objectives • Analyze effectiveness of tree planting in mitigating UHI effect • Are residences with NW trees any cooler? • What is the total energy reduction since 2002? • Tree locations vs. surface temp. over time • Spatial patterns? • What’s an appropriate time interval? • Repeatable methods for future analysis

  4. Data Sets & Tools • NW tree delivery locations (2002-2014) ftp://ftp.ci.austin.tx.us/GIS-Data/PARD/Alan/ • National Tree Benefits Calculator http://www.treebenefits.com/calculator/index.cfm • Surface temperature imagery • http://earthexplorer.usgs.gov/ • http://blogs.esri.com/esri/arcgis/2014/01/06/deriving-temperature-from-landsat-8-thermal-bands-tirs/ • CoA GIS/Map Downloads ftp://ftp.ci.austin.tx.us/GIS-Data/Regional/coa_gis.html
