US Department of Energy Study Highlights Energy Saving Potential of Sorbent Ventilation™ Technology


WESTWOOD, Mass., March 9, 2022 /PRNewswire/ — enVerid systemsthe leader in sustainable indoor air quality (IAQ) solutions, today announced that its absorbent air cleaning technology for HVAC load reduction has been validated by the U.S. Department of Energy (DOE) High Impact Technology (HIT) Catalyst program. Validation comes after field testing of enVerid’s HVAC load reduction® (HLR®) by the DOE’s National Renewable Energy Lab (NREL) in commercial buildings in the eastern and southern United States. NREL has found that HLR modules offer significant heating, ventilation, and air conditioning (HVAC) energy savings and load reduction potential. Powered by enVerid Sorbent Ventilation Technology (SVT), HLR modules safely remove carbon dioxide, ozone, formaldehyde and a wide range of volatile organic compounds (VOCs) from indoor air so ventilation rates can be optimized to improve efficiency energy efficiency and IAQ, which can lead to reductions in HVAC equipment costs, operating costs and building carbon emissions.

DOE’s HIT Catalyst program conducts assessments of new energy efficiency technologies in coordination with the US General Services Administration’s (GSA) Green Proving Ground (GPG) program. NREL has evaluated enVerid’s HLR modules in commercial and educational buildings located in hot, humid, and cold climates across the country. The findings were published in the report, Validation of the energy performance of a gaseous air purification technology for tertiary buildings. The GSA has released the NREL report and an infographic with the report’s key findings on the Results page published by GPG.

“Addressing the building of decarbonization and resilience is among our top priorities,” said Kevin Powell, director of the GSA’s Green Proving Ground program. “NREL’s assessment gives us valuable insights into where adsorption air cleaning technology will help save energy and achieve the net zero carbon goals set out in the recent Executive Order. “

Based on the NREL findings, the DOE’s Better Buildings Initiative also identified absorbent ventilation air purification technology as a step that building owners and operators can implement to achieve smart goals, healthy and low carbon. small offices, large officesand primary schools in the Best Buildings Low Carbon Technology Strategies Toolkit.

“NREL’s validation of the power-saving capabilities of enVerid’s HLR modules and its underlying sorbent ventilation technology in real-world applications is another key affirmation of this technology,” said Christian weeks, CEO of enVerid Systems. “Sorbent ventilation technology can be used to achieve the dual priority of healthy indoor air quality and lower HVAC energy intensity to reduce carbon emissions from buildings. The timeline for this important development aligns well with the measures taken under the Law on Investment and Employment in Infrastructure and The recent engagement of the Biden administration prioritize decarbonization across 370 million square feet of space in 9,600 buildings overseen by the GSA, addressing IAQ, carbon emissions and building resilience.”

SVT and IAQP – A compelling combination
enVerid’s SVT, the core technology of HLR modules and other SVT-enabled HVAC systems, when applied in combination with the ASHRAE 62.1 Indoor Air Quality Procedure (IAQP), allows air cleaned interior to replace some of the outside air needed to maintain an acceptable interior. air quality in a manner that fully complies with applicable building codes. This is an important consideration because large volumes of outdoor air are very energy intensive to condition and outdoor air is increasingly compromised by pollution and smoke from wildfires. By using SVT in combination with IAQP, annual HVAC energy consumption can be reduced by up to 40%, dramatically reducing a building’s energy intensity and carbon emissions without compromising indoor air quality .
