HVAC Load Reduction From EnVerid Systems

Modules that employ this company's HLR Technology improve indoor air quality while reducing HVAC energy consumption.

enVerid Systems Inc. provides its HVAC Load Reduction® (HLR®) technology to help facility managers, building owners, mechanical engineers, and architects achieve energy savings and indoor air quality improvements related to HVAC equipment. The technology, embodied in enVerid’s HLR module, “cleans” indoor air of contaminants such as carbon dioxide (CO2), formaldehyde, volatile organic compounds (VOCs), and particulate matter (PM2.5). Meanwhile, the technology reduces HVAC equipment energy consumption by 20-40%.indoor air

“We are committed to shaping the future of the building industry,” said Dr. Udi Meirav, founder and CEO of enVerid. “Our pioneering technologies are already helping to boost energy efficiency, cost savings, and improve indoor air quality in commercial buildings worldwide.”

Traditionally, commercial buildings replace all of their indoor air with outside air every one to two hours to prevent high concentrations of indoor pollutants. While the process helps limit these pollutants, the high volume of outdoor air must be heated or cooled to maintain comfortable temperatures and humidity inside the building. This represents 30-50% of the total load on HVAC systems in most climates, asserts enVerid, resulting in higher first cost on HVAC systems and higher ongoing energy costs.

By cleaning and recycling indoor air instead of constantly replacing it with outside air, enVerid’s HLR system decreases the outside air intake required to ventilate a building by 60-80% and also reduces peak HVAC capacity. Moreover, with HLR technology, buildings can invest in lower-capacity and less expensive HVAC systems, and benefit from decreased maintenance costs and extended life of existing equipment. The HLR technology is also eligible for local utility rebate programs and has earned LEED credits.

enVerid’s HLR system interfaces with air handling units using built-in connections. It then operates in conjunction with the air handling units.

enVerid has been deploying HLR modules since 2012, including with universities and major corporations. The technology has been endorsed by the U.S. Department of Energy and is also compliant to the standards for ventilation defined by ASHRAE.

In January 2017, Johnson Controls introduced its YORK EcoAdvance™ HLR module powered by enVerid’s technology. The EcoAdvance module is easy to install in conjunction with air handling units, energy recovery ventilators, or rooftop units. Johnson Controls notes that a Fortune 10 technology company implemented HLR technology and earned 14 LEED points by leveraging the Indoor Air Quality Performance pilot credit (EQpc68) and energy efficiency credits.

This week, enVerid announced that Shanghai-based China Europe International Business School (CEIBS) has achieved superior indoor air quality per the U.S. Environmental Protection Agency (EPA) standards, and 80% reduction in the utilization of outside air, through the installation of enVerid HLR modules in its lecture theater.
