Now that the California Energy Commission (CEC) is focused on solar + storage commercial buildings, it’s time to think beyond panels on the roof. The CEC recently awarded NEXT Energy Technologies with a $3 million grant to advance and demonstrate its glass-coating technology process for fabrication of solar power-generating windows. The project, “Rapid Innovation Development of Energy Generating Windows for Zero-and Negative-Carbon Emission Buildings,” was awarded to NEXT after the successful demonstration of directly coating its existing proprietary organic semiconducting technology onto large sheets of heat-treated glass. The method will allow for a more seamless application into the window manufacturing process that leads to much higher margins with low capital cost equipment.
“This project will allow us to demonstrate our manufacturing method of printing our PV film directly onto large sheets of heat-treated window glass. Our solution enables reduced distortions in the glass during the coating process and allows the commercial glass to be suitable for precision coatings,” said Corey Hoven, founder and CTO at NEXT. “Our model is designed to serve window manufacturers at the point of fabrication, allowing them to increase the value of their products with absolutely minimal disruption. Demonstrating our coating process is key to this seamless integration approach.”
NEXT’s PV coatings are applied to commercial windows during the window fabrication process, integrating with existing manufacturers without disrupting established workflows and supply chains. This capital-efficient business model reduces risks to customers, removes barriers to adoption, and accelerates speed to market, all while creating a high-value product.
Direct integration into traditional commercial window and framing systems diminishes the costs typically associated with the packaging and installation of solar energy solutions. “The Energy Commission is proud to support the continuing development of NEXT Energy Technologies’ game-changing window technology,” said CEC chair David Hochschild. “Their novel application of solar technology will help commercial buildings become more energy- efficient and will help California advance its nation-leading climate and energy goals.”
On August 11, 2021, the CEC adopted the 2022 Building Energy Efficiency Standards (Energy Code) for newly constructed and renovated buildings to support the state’s public health, climate and clean energy goals.
In a press release, CEC Commissioner, J. Andrew McAllister stated “The 2022 Energy Code firmly pivots California’s buildings toward the clean, low-carbon technologies that are the bedrock on which our collective path forward will rest. This foundation will help the state meet its critical long-term climate and carbon neutrality goals,”
The 2022 Energy Code includes plans to expand solar PV systems and battery storage standards for all California buildings, a step forward in the state’s goal of 100% clean electricity grid. The Energy Code will be submitted to the California Building Standards Commission (CBSC) and, if approved, will go into effect on January 1, 2023.
To support the state’s goal, and to meet other international energy standards, NEXT is working to repurpose a traditionally energy-inefficient building material to reduce commercial buildings’ energy consumption. Installed in a typical commercial high-rise office building, the first generation of NEXT windows will offset as much as 10-20% of its power needs, and over a 30-year period, such a building would produce about 20 million kWh of clean power, saving an average of $170,000 annually on utility bills and reducing 14,500 metric tons of carbon dioxide from the atmosphere, the equivalent of powering 1,700 homes for an entire year. In the coming years, NEXT windows will
be commercially available for window sizes up to 5 ft. x 10 ft (1.5 x 3 meters).
The announcement of this grant comes just weeks after NEXT delivered a proof-of-concept solar window wall to its partners at Bouygues Construction
Have you checked out our YouTube page?
We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.
Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
