3M Thinsulate Window Film Helps with LL97 Compliance & Long-Term Utility Savings

"We are going to ban the classic glass and steel skyscrapers, which are incredibly inefficient." - Former Mayor Bill de Blasio

Why NYC's LL97 Requires Your Immediate Attention

New York City has pledged to reduce greenhouse gas emissions (40% by 2030 and 80% by 2050) for a greener tomorrow.

New legislation, titled Local Law 97 (LL97), is an ambitious program that requires owners to reduce their buildings’ carbon emissions by bringing attention to a building’s envelope efficiency in addition to lighting and HVAC. Failure to comply with the new law will result in significant penalties.

Glass-intensive skyscrapers are especially under scrutiny. They look great, allow in a lot of natural light, and provide fantastic city views. Despite the use of high-efficiency glass, these building envelopes are still energy inefficient because of the amount of glass incorporated into their curtainwalls.

Buildings account for

According to the DOE, windows are responsible for as much as

of the total cooling load in commercial buildings.

The Clear Solution: 3M Thinsulate Climate Control Window Film

3M Company can reduce the inefficiencies of an existing window with an invisible retrofit product that they have been manufacturing for over 50 years — window film. The technology of window film has drastically evolved over these past 50 years to the point where 3M Thinsulate Climate Control 75 is almost the equivalent of window replacement.

Installing climate control window film is like adding an additional pane of glass because it can reduce your existing window’s solar heat gain coefficient and U-Value, which allows your building to consume less energy to heat and cool twelve months out of the year ⁠— all without changing your building’s appearance!

A Cost-Effective, Quiet & Quick Solution to Compliance

Summer Savings

When it is hot outside, much of the sun’s energy or heat is coming into a building through its glass. It is that transmitted energy that causes problems such as uncomfortable temperatures, the need for air conditioning, temperature imbalances, and glare. Applying window film decreases the amount of solar energy transmitted through the glass, resulting in a cooler, more comfortable interior and reduced need for constant air conditioning.

Winter Savings

When it is cold outside and you’re running your heating system, much of that heat is escaping the building, especially through its glass. Window film reflects much of that heat back inside, which means the room stays warmer and you use your heating system less.

Mitigating solar heat gain in the summer and heat loss in the winter helps reduce a building’s energy consumption, utility bills, greenhouse gas emissions, and carbon footprint.

Window Film vs. Window Replacement

Window replacement is costly, disruptive to tenants, noisy, and environmentally unfriendly, as the old window units get thrown right into a landfill. But that’s not the case with 3M Thinsulate Climate Control 75 Window Film. The installation process is cost-effective, quiet, and quick. And because we’re installing a plastic film to the glass rather than an additional glass pane, there are no structural load implications.

Cost of window replacement:

$1,000

Cost of window insert:

$1,000

Cost of 3M Thinsulate:

$100
