Announcing Demonstration Projects—New Self-Shading Window System
Ushers in Next-Generation Energy Efficiency Technology 


InVert™ Self-Shading Window System Responds Intuitively to Reduce Energy Consumption from Air Conditioning by 25%


January 6, 2021,  Long Beach and Hawthorne, CA — Today in Long Beach, CA and Hawthorne, CA, two demonstration projects of the InVert Self-Shading Window System open to the public. 


The InVert™ Self-Shading Window technology is poised to upend conventional energy efficiency technology because it works independently, requiring no electricity, no controls and no human intervention to reduce energy consumption from air conditioning by 25 percent. 


Thermobimetal Smart Materials inside a standard window cavity curl to block the sun at different angles as it moves across the sky. The self-shading window blocks solar heat gain yet maintains 65 percent of the natural light and color spectrum, versus just five percent of the natural light that comes through from other black-out shading systems. The connection with nature leads to higher productivity and overall improved wellness for building occupants. 


“The InVert Self-Shading Window is ready for commercialization, and visiting a demonstration project now is a great opportunity for developers and architects to watch the dynamic Smart Materials in action,” said Karen Sabath, TBM Designs CEO and co-founder. 


“Using Smart Materials in a new way delivers next-generation technology so that buildings can be both beautiful on the outside and healthy for occupants on the inside, while at the same time saving energy and reducing carbon emissions,” said Doris Sung, InVert inventor, architect and TBM Designs co-founder.

The two demonstration projects will not only show the InVert system working dynamically to block the sun, they will also validate energy reduction and financial savings and measure interior sunlight and color spectrum. 

“Having worked on policies and pilots to increase the energy efficiency of our building stock for over 25 years, I know the importance of next-generation technologies like LACI-startup TBM Designs is piloting with CSU Long Beach,” said Matt Petersen, LACI CEO. “As roughly 20% of all the energy we use in the U.S. goes to power commercial buildings, we need to continue to find innovations to increase efficiency of new buildings while doing the hard yet essential work of upgrading our existing buildings.

About TBM Designs


InVert™ Self-Shading Windows use smart thermobimetal inside a standard window cavity to dynamically block solar heat gain and reduce our reliance on energy. Using zero energy and no controls, the individual pieces respond to the sun and curl to block solar radiation from entering the building using up to 25% less air conditioning and reducing greenhouse gas emissions. InVert retains high levels of natural daylighting and full-color spectrum-both essential to human wellness-by using no film on the glass. Its magical beauty keeps humans in tune with nature and the environment. More information at
