A:According to some studies and some LEED documentation vegetated roofs have a longer product life than conventional roofs. Maybe that is due to the yearly maintenance and upkeep that should occur.
B:Life cycle costing (LCC) is the evaluation of the total cost of a building or product over its useful life, including initial, maintenance, repair and replacement costs as well as savings. LCC evaluates economic performance.
