Increased energy savings with LLumar solar control window film.


Faced with rapidly rising energy costs, Kona Community Hospital turned to NORESCO, a leading Energy Services Company (ESCO), to help them identify a solution. Because of its limited budget, the hospital needed something affordable to implement, while also delivering fast payback through resulting energy savings.


Following an energy analysis and review of the hospital’s glass requirements, NORESCO recommended LLumar reflective solar control window film R 20 SR PS4 for all exterior windows. The project required more than 2,800 square meters of window film. Professional installation was completed quickly without disrupting hospital operations and had impressive results.


In reducing summer solar heat gain by 75%, LLumar solar control window film provided the energy savings required, while also improving occupant comfort and reducing distracting glare. As an added benefit, the reflective silver film enhanced the exterior appearance of the building by hiding previously visible clutter and offering a clean, contemporary look. Due to improved energy efficiency, the project paid for itself in energy savings in less than three years.

LLumar window film is professionally installed by trained technicians and is backed by a Manufacturer´s limited warranty.
