Climate change is one of the most threatening issues that humankind faces in the 21st century and there is indisputable evidence that our planet is experiencing global temperature rise, shrinking of ice sheets and sea level rise, warming oceans, and extreme weather events at an alarming rate. Urbanization drives these changes and creates the Urban Heat Island (UHI) effect. One method to mitigate this issue is urban greening, specifically the construction of green walls which take advantage of unused vertical exteriors of buildings. Despite existing literature on green walls especially in Europe and Asia, green walls must be researched more in all climates to better understand how different variables impact overall thermal performance. This will ultimately inform effective design, making green walls more cost-effective.
This study will examine the thermal performance of a small-scale green wall in the cold climate region of New England in the United States. A hot box apparatus will be used to measure the heat flux through the green wall and the R-value will be estimated and compared to that of a bare wall. Heat3 will be used to perform fluid modeling and SAP2000 will be used to perform structural analysis.
