Simplifying Energy Efficiency Procurement
Government agencies are under strict directives to improve building energy efficiency, often guided by EPA and ENERGY STAR frameworks. While large-scale HVAC replacements or full window retrofits require massive budgets and complex contracting, solar control window film represents a highly effective, low-barrier alternative. For procurement officers, purchasing solar film rolls as a supply-only transaction is one of the most straightforward ways to advance agency energy goals.
The U.S. Department of Energy (DOE) emphasizes that window films applied to the glazing surface help block solar heat gain, protect against glare, and reduce ultraviolet exposure [1]. Because window film is rated by the National Fenestration Rating Council (NFRC) — the same body that certifies ENERGY STAR windows — agencies can confidently procure materials that deliver measurable, verifiable energy savings [1].
Why Supply-Only Makes Sense for Agencies
Many government facilities, from state offices to military bases, employ skilled in-house maintenance and engineering teams. Leveraging these teams to install window film offers significant advantages over traditional contracted installations:
| Procurement Model | Advantages | Disadvantages |
|---|---|---|
| Contracted Installation | Requires no in-house labor; turnkey solution. | High costs; complex bidding processes; prevailing wage requirements; scheduling delays. |
| Supply-Only (Bulk Rolls) | Maximizes budget; rapid procurement via P-Card; immediate availability for phased deployment. | Requires in-house maintenance staff to perform the application. |
The DOE explicitly notes that window films are "available for do-it-yourself projects" [1]. The Efficient Window Coverings Collaborative further confirms that while professional installation is an option, applied window films can be successfully installed by competent facility staff [2]. By purchasing bulk rolls, agencies can stretch their end-of-year budgets further and apply the film incrementally as time and resources permit.
Aligning with EPA and ENERGY STAR Goals
While ENERGY STAR primarily certifies complete window units rather than applied films, the underlying performance metrics are identical. The NFRC label on window film provides the exact same data points used to evaluate high-performance windows:
- Solar Heat Gain Coefficient (SHGC): Measures the film's ability to block heat. Lower numbers indicate better cooling season performance [1].
- Visible Transmittance (VT): Measures how much natural light enters the space, which is critical for reducing reliance on artificial lighting [1].
By selecting solar film rolls with low SHGC ratings, agencies directly support EPA initiatives to reduce greenhouse gas emissions by lowering the electricity demand required for air conditioning. In climates with long cooling seasons, the DOE notes that these films are particularly effective because they block the sun's heat before it can elevate interior temperatures [1].

Frequently Asked Questions
Are window films ENERGY STAR certified?
ENERGY STAR generally certifies complete window assemblies rather than aftermarket films. However, window films are certified by the NFRC (National Fenestration Rating Council) — the exact same organization that provides the performance data (SHGC and VT) used to determine ENERGY STAR eligibility for windows [1].
Can government maintenance teams install window film themselves?
Yes. The DOE acknowledges that window films can be applied as do-it-yourself projects [1]. For skilled facility maintenance teams, applying commercial-grade window film is a manageable task that significantly reduces overall project costs compared to hiring outside contractors.
What is the best climate for solar control window film?
According to the DOE, solar control window films are best used in climates with long cooling seasons, as their primary function is to block the sun's heat and reduce air conditioning loads [1].
