Clear glass to dark Prussian Blue with the push of a button.
Dynamic electrochromic (EC) glass that switches from a clear to a tinted state when voltage is supplied is now technically viable. This enables the architect and engineer to work together to lessen reliance on expensive automated blinds and fixed-exterior shading strategies, while reducing solar gain and the size of the HVAC system. Our early research indicates that the pimary costs to employ electrochromic glass will pay for itself in a few years, and provide savings for decades.

EC glass can be specified for the building’s exterior, or zoned to address solar gain where blinds or shading are being contemplated. It comes in four colors: classic, green, blue and gray, or can be customized to compliment the non-EC glass.
How does Electrochromic glass work?
Electrochromic (EC) glass can be operated manually with dimmers, automated with simple sensors, or integrated into an automated building management system. The glass panes, manufactured by any number of glass manufacturers, are sent to the EC glass factory and coated with five layers of ceramic materials, which have a total thickess that is less than 1/50th of a human hair. When voltage is applied across the coatings, ions travel from one layer to another layer, where a reversible solid-state change takes place, causing the coating to tint and absorb light. Reversing the polarity of the applied voltage causes the ions to migrate back to their original layer, and the glass returns to its clear state.

Nectar CleanTech is currently investigating this technology.
Given the immense energy-saving potential for digitally controlled solid-state glass, Nectar CleanTech researched the field of manufacturers to see if this technology is currently affordable, and is determining its future potential to contribute to a buildings overall energy efficiency. While early yet, our findings indicate that where solar gain control calls for integrated window blinds or exterior fixed shading structures on skylights or windowcurtains, electrochromic glass is an affordable alternative. We are working with several clients on projects to validate the energy savings and to measure the return on investment.

From an industry perspective, initial key indicators for near-term viability include dozens of existing case studies ranging from schools, clubs, and architecture firms, along with recent DOE-certified laboratory testing indicating a lifespan of 30 years with minimal loss of efficacy.

Our investigation goes beyond the science as well, as the manufacturing process has to be able to handle volume, and the manufacturer‘s finances have to be viable over time. We found that the leading technology manufacturer, operating out of their current facility since 2005, is building a much larger plant that will soon be able to coat 5’ X 10’ glass, and the company is well-funded.
