3D finite element modeling of recycled glass cullets in asphalt shingles

Recycled glass cullets in asphalt shingles may be utilized as a cool roof strategy to reduce the harmful effects of Urban Heat Island (UHI). A Three-Dimensional (3D) transient Finite Element (FE) model was developed and validated to quantify energy savings provided by the proposed recycling process under various climatic conditions. Simulations were carried out for three cities located in three climate regions in the United States representing different climatic conditions. The three cities representing each region were Kansas City (Missouri) for Zone 3, Charlotte (North Carolina) for Zone 4, and Miami (Florida) for Zone 5. Results for each of the climatic zones were quantified. Results showed that the annual energy savings ranged from $35.37 in cold climatic regions to $ 92.58 in hot climates.Non UBCUnreviewedFacultyOthe
