What type of return on investment or simple payback would these energy savings provide?
Though they provide similar energy savings, window films are much cheaper to install than replacement window – about 5-10% of the cost. Therefore, the capital investment is much lower for window film. Many projects produce a simple payback in less than three years (when including utility company rebates) – equivalent to a 33% return on investment!
