UPDATE: Heliotrope declared insolvency in Nov. 2021 and this project is no longer active.
Heliotrope's NanoEC is the first neutral grey electrochromic window product that achieves a price point less than $25/sq. ft. This project is aiming to evaluate and optimize the building energy impact of this electrochromic smart window. By reaching the color/cost barriers needed to create mass adoption, Heliotrope will use this project to design, test, and validate energy conservation in building applications through field installations at both a test bed facility and at a real world commercial facility. Data from this study will help optimize window tinting control algorithms to achieve the lowest building energy consumption.
Heliotrope’s NanoEC electrochromic windows is a ground breaking smart glass that has already achieve an aesthetic all pleasing neutral grey color.
Heliotrope's NanoEC electrochromic windows are estimated to have an average daily lighting energy savings of 10-15% compared to south facing static windows with lowered Venitain blinds.
