enVerid Systems: Improving Energy Efficiency and Indoor Air Quality

Christian Weeks, CEO, enVerid SystemsChristian Weeks, CEO
Conventionally, heating, ventilation, and air conditioning (HVAC) systems maintain indoor air quality by constantly replacing indoor air with air from the outside. This is necessary to remove indoor gas contaminants like carbon dioxide, formaldehyde, and volatile organic compounds (VOCs). However, outside air usually needs to be cooled or heated to match the room temperature inside a building, and this process requires a large amount of energy. In fact, almost 44 percent of all energy consumption in a commercial building today is attributed to HVAC systems. At the same time, drawing air from outside is counterproductive if the air outside is not clean, which is often the case for buildings located in cities or near highways or airports.

So, the question is whether there is a better way to maintain indoor air quality without wasting energy conditioning outside air and bringing outdoor pollutants into buildings? Thanks to proven, cost effective air scrubbing technology from enVerid Systems the answer is a resounding yes. “enVerid’s HVAC Load Reduction (HLR) technology safely and effectively removes all the molecular contaminants from indoor air, enabling buildings to reduce the required volume of outside air ventilation,” explains Christian Weeks, CEO of enVerid Systems. By reducing the need for outside air, new HVAC systems can be downsized to deliver immediate capital cost savings and all buildings can enjoy savings of up to 30 percent of HVAC energy costs while at the same time maintaining or improving indoor air quality.
enVerid’s HLR technology can be added as a retrofit to existing HVAC systems or deployed with new HVAC systems. The company’s current product offering, the HLR 15 series indoor units are designed for indoor use and can be installed inside an HVAC mechanical room or air plenum. Conversely, the HLR 15 series outdoor units are designed for outdoor use, typically on a rooftop. These models contain a cabinet, twelve replaceable sorbent cartridges, and web-accessible embedded controls and sensors. “The secret behind the HLR modules is a unique, non-toxic, eco-friendly sorbent designed to capture all the molecular contaminants found in a building without producing any byproducts,” says Weeks. And unlike most sorbents that regenerate at temperatures above 1000 degrees Fahrenheit, enVerid’s sorbent regenerates at a much lower temperature of 130-150 degrees Fahrenheit, making it safe and cost effective for indoor use. The sorbent’s cycle of adsorption and regeneration is completely automated, and the cartridges only need to be replaced annually. Building owners and facility managers can monitor the performance of the HLR system, and this includes measuring indoor air quality and real-time energy savings. enVerid’s HLR technology is fully compliant under ASHRAE Standard 62.1 Ventilation for Acceptable Indoor Air Quality.

Improved indoor air quality is also directly linked to an increase in cognitive performance. For example, a recent Harvard study found that “CO2, VOCs, and ventilation rate all had significant, independent impacts on cognitive function.” For companies seeking to improve employee performance and well-being, enVerid’s solution can provide a better environment in the workplace. Further, to help reduce pollution, enVerid aids their clients to build green buildings. By incorporating HLR technology into HVAC designs, organizations can earn Leadership in Energy and Environmental Design (LEED) points, one of the most popular green building certification programs used worldwide. For instance, with enVerid’s help, Southwest Florida Community Foundation was awarded the first LEED Gold Certification using new indoor air quality pilot credit from the U.S. Green Building Council. In another instance, a financial institution headquartered in New York City was able to meet energy savings goals and was able to save more than USD 200,000 in a year.

enVerid has had HLR units operating in the field since 2014 and has had energy savings generated by its HLR modules validated by the U.S. Department of Energy and multiple utilities and third-party evaluators. In 2019, enVerid was awarded the AHR Expo’s prestigious Product of the Year Award. enVerid is currently collaborating with over 160 consulting engineering firms in the U.S., helping them to adopt HLR technology into their commercial building development projects. In response to growing demand for HLR technology, enVerid plans to expand to new territories in North America in 2020.

From a technological standpoint, the company is currently developing a more compact version of the HLR 15 series, which will be appropriate for use in smaller spaces such as conference rooms, hotel guest room, or multi-family buildings. With such innovation in the HVAC and commercial building market, enVerid is committed to developing solutions that make the world a cleaner and healthier place to live in.
