Green Roofs for Healthy Cities (GRHC) Most candidates entering the GRHC exam arrive with backgrounds in landscape design, horticulture, or civil engineering. Foundational knowledge of stormwater management, plant biology, and building codes forms the typical baseline. Those without prior experience in green infrastructure or rooftop systems often find the soil composition and waterproofing membrane sections particularly demanding, requiring supplementary study before test day.
