EFFECTS OF DESIGN AND OPERATING PARAMETERS ON GREEN ROOF THERMAL PERFORMANCE IN MELBOURNE

Abstract

The growing interest in extensive green roofs prompts more refined studies on green roof design and operation. To assist in the design, installation and operation of green roofs, the effects of design and operating parameters on green roof thermal performance need to be fully understood. The effects of two design parameters: substrate thickness (ST), conductivity of dry soil (CDS) and four operating parameters: leaf area index (LAI), leaf reflectivity (LR), stomatal resistance (SR), moisture content (MC) were investigated using the green roof model developed by Sailor in 2008. The sensitivity analysis revealed that among the operating parameters, LAI has the largest effects on thermal perfor..
