Green roof performance in Los Angeles, California

UnrestrictedGreen roofs have recently become popular solutions to help combat the growing climate crisis. Most of the information available focuses on the benefits recorded in the temperate regions of the United States. Almost no information appears to address the implications green roofs could have in the semi-arid climate ofthe southwestern U.S.; This paper aims to determine if the same benefits recorded elsewhere in the U.S. will be noticeable in Los Angeles, California. The author compared the performance of a low-cost green roof with a base case conventional insulated roof to discuss the interior behavior of a green roof in a semi-arid climate. The analysis of the temperature data indicate that, although it may not have as large a benefit as in other locations in the U.S, a green roof will provide enough of a difference in interior air temperature during warm weather months to be beneficial in southern California
