Life-Cycle Calculator

Tremco introduces the first version of its GreenSave Life-Cycle Cost-Benefit Calculator from Tremco for comparing green roofs to conventional roofs. It determines the lowest cost investment for a specific roofing requirement over a specific time frame.


The calculator is useful in determining whether the initial cost of an investment is justified by reductions in future costs such as operating, maintenance, repair or replacement costs. It can capture roof benefits, such as storm water and heat island mitigation, extended roof durability, related energy costs and savings, development fee savings, marketing benefits, increased rentability and tenant health.
