While considering both product and procurement technicalities, the priorities in Government Buildings anticipated by Edge window film are as follows:
- Energy – energy savings continues to be the primary historical reason government buildings consider window film. With governmental leadership offering continued energy efficiency, Edge window films often come in as the next best return on investment (ROI) after a lighting retrofit. Since most, if not all, governmental buildings have undergone lighting retrofit in the last five (5) years, Edge window films can be the energy efficiency technology with the best ROI available. While offering energy savings and improved comfort with safety and security, government procurement agencies can turn multifaceted Edge window film solutions into several different agencies for solutions-based funding.
- Storm – governmental tenants and records are at high risk for property and personal loss due to high-energy storms. Whether the loss of irreplaceable records or the governmental tenant is left to replace carpeting, drywall, and furnishings after a storm breaks out windows, these financial losses caused by water inside the building envelope can dwarf the cost of replacing the glass itself.
- Blast – while the probability of storm damage is quite high in certain geographies, the probability of bomb blast is relatively remote. However, the cost in a blast scenario is typically in lives rather than dollars and cents. Couple this fact with the expectation that bomb blast threats will be focused in areas of dense population and you can see why Government Buildings continue to be a prime target for terrorism. Although many buildings do not consider themselves targets of terrorism, the attack on the Oklahoma City Federal Building in 1995 left buildings as far away as 10 city blocks with broken and flying glass. U.S. Representative (Texas) John Culbertson stated “The Murrah building lacked a simple security measure, safety window film…This film acts like a barrier between an explosion and a victim…it contains the glass — holding it together…you don’t have the sharp-edge projectiles that caused massive loss of life. Measures like this would have saved countless lives.”
