Energy Modeling for LEED

How to Document Savings

1. Baseline Energy Model — Create model without window film
2. Proposed Energy Model — Add window film specifications
3. Simulation — Run energy simulation for both scenarios
4. Comparison — Calculate percentage improvement
5. Documentation — Submit to LEED review

Software Tools

• EnergyPlus
• eQUEST
• TRACE 700
• IES VE

Typical Results

• Prestige Series: 35-50% cooling energy reduction
• Ceramic Series: 25-40% cooling energy reduction
• Combined with insulation: 40-60% total energy reduction

Implementation Strategy

Phase 1: Assessment

• Energy audit of existing building
• Glass inventory and condition assessment

FAQ

How many LEED points can window film earn?

Window film can contribute 10-23 LEED points depending on the building and application. This can be the difference between certification levels.

Is window film required for LEED certification?

No, but it's one of the most cost-effective ways to earn energy and comfort points. Many LEED projects use window film to achieve their target certification.

Can existing buildings use window film for LEED?

Yes. Window film is ideal for existing building retrofits. It can be installed without disrupting building operations.

Does window film affect LEED's daylight credits?

Quality window film maintains daylight while reducing heat and glare. It can actually improve daylight quality by reducing hot spots.
