High IAQ with energy efficiency
Air Movement, Fans & Ventilation
ENVERID SYSTEMS HAS published a system- level framework for enabling low-energy, high IAQ, climate-resilient buildings.
The Clean First approach is detailed in a new white paper which was developed in collabora- tion with leading IAQ and energy efficiency com- panies and includes input from more than a dozen built environment experts.
The Clean First framework is based on a four- step process that building owners and operators, architects, energy efficiency consultants, and mechanical engineers and contractors can fol- low to achieve Sustainable IAQ: better indoor air quality, more energy efficiency with improved resilience to outside air pollutants, including wildfire smoke and ozone.
The framework draws on lessons learned from the pandemic and recent updates to build- ing standards to address the growing need to decarbonise both new and existing commercial buildings while simultaneously improving IAQ.
The core thesis of the paper is that improving IAQ with optimised ventilation and air cleaning need not conflict with building decarbonisation and climate resilience goals and, in many cases, can reduce a building’s carbon footprint.
ASHRAE president, William Bahnfleth, said to create high IAQ, low energy, climate resilient buildings for the future organisations need to embrace alternatives to outside air ventilation to maintain healthy indoor environments.
“Building on key lessons from the COVID-19 pandemic about layered air cleaning strategies, the Clean First framework presented in this paper lays out a well-constructed, system-level approach to achieve Sustainable IAQ. I encour- age designers and engineers to read the paper and consider incorporating its recommendations into future projects.”
enVerid Systems CEO, Christian Weeks, said it is time to embrace a Clean First approach to designing and operating buildings to deliver

healthy indoor air quality while also conserving energy and reducing carbon emissions.
“For too long we have been constrained by a false choice of better IAQ or increased energy efficiency from reducing ventilation rates.
“The Clean First framework shows how com- bining field validated air cleaning, filtration, and ventilation strategies using existing build- ing standards with continuous IAQ monitoring and dynamic building controls can deliver good IAQ and improve ventilation efficiency at the same time.”
