UVCUE

Meet the new ASHRAE standard 241 while reducing the building's energy load

Layered IAQ Strategy

Upper-Room GUV for today

Protection against respiratory diseases has become even more important as Covid-19 has joined the flu as a recurring disease, and concerns about infectious diseases are at an all-time high.

At the request of White House, ASHRAE Standard 241 has established the level of clean airflow necessary to protect against airborne pathogens, typically 3-4 times the current building code.

Upgrading ventilation systems to meet ASHRAE 241 is extremely costly, both in initial and annual costs, and significantly increases the carbon footprint. It also disrupts normal building use, as all the vents in the building need to be resized when done properly.

Upper-Room GUV:
Layer of air disinfection to help meet the enhanced standard in ECA 241

Unlike other technologies, Upper-Room UVGI has been studied for decades and is proven to be the most scientific, cost-effective and sustainable option as an indoor air disinfection strategy for densely occupied spaces. It is recommended by the CDC, ASHRAE, Harvard, Yale, and PNN. UVCUE is our version of the Upper-Room GUV solution that can help meet the new ASHRAE 241 standard.

How does Upper-Room UVGI work?

Because hot air rises, body heat causes exhaled breath to rise in a phenomenon called the “Human Thermal Plume.” This, along with mechanical air mixing, causes air to enter the disinfection zone above people’s height, continually inactivating airborne pathogens.

Installing Upper-Room UVGI is low-cost at $1-$2/sq ft, compared to HVAC upgrades that can cost up to $30/sq ft. Annual energy costs are 10-20 times lower than conventional HVAC for providing an equivalent level of clean airflow.
“So really about the only thing that seems practical is something like Upper-Room UV which we've got again here, a 254nm system.”

Bill Bahnfleth, Past President of ASHRAE and the Chair of Standard 241

Airborne Efficacy Test

The UVCUE units are designed to be installed high on the walls to create a UVC zone overhead. Airborne microbes enter the UVC zone due to thermal plume from body heat and ventilation, and are inactivated at a rate determined by the microbe’s susceptibility to UVC energy.

Third Party Verified

The table below shows the third-party testing results where listed microorganisms were aerosolized into the air and suspended using mixing fans. UVCUE units were installed at 7 feet. Air samples were taken at specified intervals and compared to control samples with the UVCUE unit off.

UVCUE Third Party Test Result

Above tests were performed by Intertek in a 10’ x 10’ x 10’ chamber with a temperature range of 70 degrees to 75 degrees and a relative humidity range of 48% and 57%. The chamber was sealed and mixing fans were used to provide buoancy to the microbes and mix the air within the chamber. Significant changes in airflow, chamber size, temperature, humidity, or other environmental factors may impact performance. The reduction rates of microbes to UVC energy depend on the UVC susceptibility of the microbe in question.
