Where to Buy
Life Cycle Cost Savings
Life Cycle Costing (LCC) aims to quantify the financial impact of a product over its entire life cycle to assist consumers in making decisions that will save them money over the long term.
GSA's Proving Ground found that installation of Hi-R panel retrofits could provide as much as a 41% heating savings in winter, or an 11% estimated savings for an entire buidling's heating and cooling demand. Estimated payback is 9 years for triple-pane retrofits and less for double-pane retrofits.
Contributes to meeting The Guiding Principles for Sustainable Federal Buildings
Highly insulating window panel retrofits are installed on top of existing windows. GSA's Green Proving Ground recommends double-pane retrofits for buildings in cold climates with single-pane windows but notes that site-specific evaluation is critical.
