Researchers at the University of Toronto demonstrated a window technology that utilizes multiple layers of plastic sheets that can be filled with different pigments to selectively filter infrared (IR) heat and/or visible light. This approach has the potential to dramatically reduce HVAC energy requirements for buildings. Different layers within the prototype window filter out infrared [...]

Tony Esposito and Kevin Houser published a new study in Scientific Reports demonstrating that CCT is not suitable for predicting the biological potency of light. The experiments utilized a 5-channel LED lighting system to show that significant variation in CS and EML/mEDI exists at any fixed value of CCT and photopic illuminance. For many years, [...]

A research team from Sejong University in South Korea has demonstrated a new system which uses infrared light to safely transfer high levels of power. Laboratory tests showed that it could transfer 400 mW of light power over distances of up to 30 meters.

Scientists have developed an efficient new way to convert methane into methanol at room temperature. The technique could help reduce greenhouse gas emissions and provide a much cleaner way to make green fuels.

Research conducted in 2020 indicates that the control of light impacts indoor environmental quality (IEQ)-productivity belief more than other IEQ control.

In a newly published study, researchers from Binghamton University’s Thomas J. Watson College of Engineering and Applied Science answer many of the questions about UV disinfection of the virus that causes COVID-19, and lay the foundation for health standards about what offers true disinfection.

In September 2021, the US Department of Energy (DOE) published a research study about how users and stakeholders engage with connected lighting systems (CLS) and make decisions during each step in the supply chain process, from production to operation, in commercial buildings in the United States.

A team of researchers have recently published new research on window views from within buildings and have proposed a new framework for designing “view quality” for window views.  The team identified three critical factors in determining view quality.

Researchers have discovered a new method of generating long-wavelength (red, orange, and yellow) light through the use of intrinsic defects in semiconducting materials, with potential applications as direct light emitters in commercial light sources and displays.
