Green Roofs for Healthy Cities Launches GreenSave Calculator on Web site

TORONTO - Green Roofs for Healthy Cities, in partnership with Tremco Roofing and Building Maintenance and the Athena Institute, has launched the GreenSave Calculator, a Web-enabled Life-Cycle Cost-Benefit tool that enables professionals to compare the short- and long-term costs and benefits of green roofs and conventional roofs. Designed under the leadership of Ralph Velasquez, sustainable technologies manager, Tremco Roofing and Building Maintenance; the members of Green Roofs for Healthy Cities’ Life-Cycle Cost-Benefit Sub-Committee; and the Athena Institute, the GreenSave Calculator facilitates detailed comparisons of up to three different roofing options over the defined life span of the project (typically ranging from 25 to 60 years), providing an accurate, comprehensive picture of the long range impacts of each option. Additionally, the GreenSave Calculator is capable of capturing other possible roof benefits, such as stormwater and heat island mitigation, extended roof durability, related energy costs and savings, development fee savings, marketing benefits and increased rental income.
