IAQ Guidelines and Credits

RESET, WELL V2 & LEED V4

RESET Certification:

The Air Module of RESET Certification stands as a cornerstone of its modular green building standard, with a primary focus on promoting occupant health in constructed environments. Unlike traditional standards like WELL and LEED, which permit on-site testing, RESET adopts a performance-driven approach, relying heavily on real-time sensor readings and measurements for certification.

Comprising various modules including materials, air, water, energy, and circularity, RESET places a particular emphasis on the Air Module, highlighting the critical role of indoor air quality (IAQ) in fostering health and well-being. This module applies across diverse building types, encompassing both commercial interiors and core and shell structures.

In terms of RESET Air Requirements, continuous monitoring of air quality is paramount, given its dynamic nature influenced by factors such as occupancy, user behavior, and seasonal fluctuations. The Air Module mandates constant measurement of five key parameters: particulate matter (PM2.5), total volatile organic compounds (TVOC), carbon dioxide (CO2), temperature, and relative humidity.

Within commercial interiors, RESET offers two distinct performance levels: acceptable and high-performance. The acceptable thresholds for PM2.5, TVOC, and CO2 are set at levels below 35 micrograms per cubic meter, 500 micrograms per cubic meter, and 1000 ppm, respectively. While specific requirements for temperature and humidity levels are not stipulated, monitoring of these parameters remains obligatory.

For high-performance standards, the thresholds are notably stringent, particularly for PM2.5 and CO2 levels. High-performance PM2.5 levels must not exceed 12 micrograms per cubic meter, while CO2 levels should remain below 600 ppm.

WELL Air Concept: 

Overview: The Air Concept emerges as a linchpin in WELL certification pursuits, wielding significant sway over compliance outcomes. Garnering up to 18 points, the Air Concept constitutes a fundamental pillar for WELL certification success. Through adept utilization of continuous monitors, buildings can secure seven points across features A01, A03, A05, A06, and A08, elevating certification prospects to lofty heights.

As a cornerstone of the WELL Building Certification (WELL v2, Q4 2022), the Air Concept assumes pole position among the ten core concepts, wielding substantial influence over certification outcomes. The Air Concept's attributes are attainable through various avenues, encompassing sensor data, performance tests, photographic evidence, engineer endorsements, and ongoing maintenance records. Within this narrative, our focus will gravitate towards features amenable to validation via sensor data or performance assessments.

A01: Air Quality Prerequisite At the vanguard of the Air Concept lies A01, delineating minimum air quality standards for targeted pollutants. Comprising five facets spanning particulate matter, organic gases, inorganic gases, radon, and measurement, A01 serves as a pivotal benchmark for achieving WELL compliance.

PM2.5: In the realm of WELL, PM2.5 and PM10 compliance manifests across three distinct trajectories. Option 1 mandates PM2.5 levels below 15 micrograms per cubic meter, verifiable through sensor data or annual performance evaluations. Alternatively, Option 2 extends a more lenient threshold, while Option 3 gauges IAQ improvements relative to outdoor benchmarks.

VOCs: The second aspect of A01 pertains to volatile organic compounds (VOCs), susceptible to measurement and management via periodic performance tests or continuous sensor monitoring.

Inorganic Gases: Aligned with VOCs, the third dimension of A01 addresses inorganic gases like carbon monoxide and ozone, subject to oversight through one-off performance tests or sustained sensor surveillance.

Radon: Part four of A01 turns the spotlight on radon, mandating engineer assurances or annual testing to ensure adherence to stringent radon level standards.

Measurement: The fifth facet underscores the imperative of annual parameter measurements, with continuous monitoring obviating the need for supplemental on-site assessments.

A03: Ventilation Design A prerequisite within the Air Concept, A03 spotlights ventilation design excellence, underpinned by adherence to established guidelines such as ASHRAE 62.1 and engineer-endorsed validation.

A05: Elevated Air Quality Optimization Exceeding minimum benchmarks, A05 accentuates enhanced air quality optimization, extending commendations for mitigating particulate matter, organic gases, and inorganic gases. Embracing these enhancements can yield a maximum of four points under this feature.

A06: Elevated Ventilation Design A06 delves into elevated ventilation paradigms, rewarding superior ventilation and air quality management. Notably, A06 underscores CO2 reduction through sensor-based evidence, affirming the efficacy of ventilation strategies.

A08: Air Quality Monitoring and Awareness Central to A08 is the promotion of continuous air quality monitoring and heightened occupant awareness, culminating in additional WELL certification points. Component 1 mandates IAQ monitor deployment, while Component 2 emphasizes widespread dissemination of air quality metrics to occupants.
