Energy Saving Window Film

Ford Motor Company

Improves employee comfort whilecutting energy costs with 3M™ Scotchtint™ Window Film

Problem

Ford Motor Company found it challenging to maintain comfortable temperatures for employees year-round in its 40-year-old headquarters in Detroit, a 12-story building faced almost entirely with glass. Glare from the sun also made it difficult for employees in the building to see computer screens.

Solution

After 40 years of trying various fixes to control temperatures in the building, Ford’s problem was solved when 3MTM ScotchtintTM RE20SIARL High Performance Silver Solar Control Window Film was applied to every one of the building’s 3,083 windows.

Results

While the most important outcome has been improved comfort for its employees, Ford says the company is now enjoying the benefits of an energy consumption reduction, which could save them an estimated $57,000 a year in energy costs.
Prior to the installation, Ford could cool the building no lower than 80 degrees on hot summer days. Now, even on 90-degree days, the building’s temperature has stayed at a comfortable 72 degrees.
The company is also enjoying the benefits of the building’s improved appearance and the reduction of glare on computer screens. In the building’s Trading Room, for instance, Ford employees had not been able to open their drapes for more than seven years, because the sunlight made it difficult to see their computer screens. Now those same employees enjoy being able to look outside during working hours.


The AON Tower with Night Vision Film

The AON Tower (62 stories) in Los Angeles
has 3M™ Scotchtint™ Night Vision Film installed to control heat and glare.

Problem

At 62 stories, the AON Tower, Los Angeles, is one of the world’s tallest buildings. To control heat and glare the building’s management had window film applied to the glass in the 1980’s. Nearly two decades later, the building was due for a facelift because of the flaw of all window films around that time. The film had a purple tint.

Solution

Operations manager David Thompson called in two competing window film dealers to test their products over a two month period. "The 3M window film outperformed the competing film in both energy efficiency and price."
"Night Vision 25 blocks solar heat by up to 59 per cent and UV rays by up to 99 per cent, and it reduces glare by up to 72 per cent, making it one of the top performers in the industry. The same technology that tones down reflectivity, also makes the Night Vision film colour stable, ensuring the colour won’t change."

Results

Preliminary results indicate that the AON Centre will realise annual energy savings of more than $200 000. Other pleasing results include fewer tenant comfort complaints, positive feedback about clearer views – even at night, and a noticeable improvement in the building’s exterior appearance.
