600 Third Avenue - between East 39th and 40th Streets- is currently undergoing a green capital improvement program that includes the installation of solar film across the 42-story tower’s 1800 windows (which total 43,000 square feet). The retrofit should be completed sometime during the first quarter of 2009 and could save owner L&L Holding Company up to $30,000.00 each year (thought it’s unclear how those savings would be allocated amongst tenants, if at all).
Solar films are manufactured by applying a metal alloy to a base film, which results in a polyester laminate with metallized coatings bound by adhesive that is applied to the interior of window glazing. Solar film can reduce UV penetration by 99 percent and solar heat gain by 75 percent. For L&L, the installation will also boost the consistency of the 500,000-square-foot building’s exterior appearance, as well as improve daylighting across interior tenant spaces.
