The GreenSave Calculator is an online tool that allows users to compare roofing alternatives over a specific time period to determine which has the lowest life-cycle cost.

This tool can be utilized to determine whether higher initial costs are justified by reducing such future costs as operating, maintenance, repair or replacement costs and/or producing additional benefits, such as energy savings, and whether some roofs have lower initial costs that inflate over time.

The GreenSave Calculator was developed to help professionals concerned with sustainability by Green Roofs for Healthy Cities and the Athena Institute with support and funding by Tremco Roofing and Building Maintenance

The GreenSave Calculator is available exclusively to GRHC Individual and Corporate Members.
