Roof Savings Calculator

From Open Energy Information

The Roof Savings Calculator was developed as an industry-consensus roof savings calculator for commercial and residential buildings using whole-building energy simulations. It is built upon the DOE-2.1E engine for fast energy simulation and integrates AtticSim for advanced modeling of modern attic and cool roofing technologies. An annual simulation of hour-by-hour performance is calculated for the building properties provided based on weather data for the selected location. Annual energy savings reported are based upon heating and cooling loads and thus this calculator is only relevant to buildings with a heating and/or cooling unit.

The Roof Savings Calculator is an R&D 100 award-winning technology made freely available for use by the general public. Companies or individuals using it for profit or sales should contact ORNL's Partnerships Directorate regarding licensing.
