Indoor Environmental Quality

Continuous air quality monitoring: data that drives action

A one-time air test gives you a snapshot. Ongoing monitoring shows how measured conditions at the monitored locations change over the monitored period: trends, anomalies, and whether improvements moved the numbers. ESG installs and manages air quality monitors, translates the data into clear insights, and provides independent consultation so you know what to do next.

The monitoring difference

Guesswork vs. measured data

Without ongoing data, building managers and homeowners respond to complaints instead of conditions. Continuous IAQ monitoring replaces assumptions with trend data, so you can spot problems early, target fixes, and see whether measured conditions changed after what you did.

Without Monitoring

Responding to complaints, not conditions

Without data, building managers run HVAC at maximum capacity regardless of actual occupancy or conditions, respond reactively to tenant complaints about air quality, and have no way to show whether an HVAC change, renovation, or cleaning protocol made any measurable difference.

With ESG Monitoring

Trends, targets, and measured improvements

ESG's ongoing monitoring shows what's typical at the monitored locations, alerts you when monitored conditions drift outside targets, and provides before-and-after trend data after HVAC changes, renovations, or occupancy shifts. Real-time CO₂ data supports smarter, demand-driven ventilation decisions.

What we monitor

Your building's vital signs, tracked continuously

ESG monitors the parameters that matter most for occupant health, comfort, and building performance. We install and manage the equipment, handle the ongoing indoor air quality data collection, and provide continuing consultation, not just raw numbers.

Humidity & temperature: comfort and moisture control; ESG can install humidity monitors and manage them remotely, issuing routine reports so moisture trends can be addressed early

Airborne particulates: dust, smoke, and allergen-related particles (PM2.5/PM10) commonly associated with comfort and air quality concerns; monitoring shows patterns so recurring issues can be addressed

CO₂ and common indoor pollutants: ventilation effectiveness and occupant-related changes; real-time CO₂ data supports running HVAC based on actual needs rather than constant maximum ventilation

Multi-zone and multi-floor coverage: monitoring includes common areas and occupied/leased spaces to understand real conditions where people work and gather, not just the lobby

Trend reports & threshold alerts: ESG translates ongoing data into actionable reports with clear thresholds, so you're notified when monitored conditions drift outside the agreed targets

Deeper diagnostics when needed: if monitoring data suggests ventilation, pressure, or filtration issues, ESG can support airflow and ventilation testing to identify the root cause

Why ESG

Monitoring plus consultation, not just a device on a wall.

Most IAQ monitoring vendors sell you hardware and walk away. ESG provides ongoing monitoring and consultation: installing and managing devices, interpreting what the data means, and advising on what to do next. Our independence from HVAC contractors and remediation firms means you get unbiased guidance grounded in science.

For commercial buildings, ESG's monitoring demonstrates a measurable commitment to indoor environmental quality, data that can support tenant conversations and premium positioning. For homeowners, ongoing humidity oversight is a practical step that helps reduce the risk of moisture problems, mold growth, and recurring IAQ issues.

We test. We never remediate. That means when ESG recommends a fix, it's because the data says so, not because we profit from the work.

Our process

From baseline to measured improvement

ESG's air quality monitoring program is built around a simple idea: data should lead to decisions. Every step is designed to give you actionable insight, not just numbers.

Common questions

Frequently asked questions

How long before monitoring data becomes useful?

Within the first few weeks, ESG establishes a baseline for typical conditions at the monitored locations. Trend data becomes most valuable after 30 to 60 days, when seasonal patterns, occupancy cycles, and HVAC behavior become visible. Threshold alerts are active from day one, so anomalies are flagged immediately.

Can ESG monitor multiple floors or zones?

Yes. ESG designs monitoring programs to cover the zones that matter, including common areas, occupied/leased spaces, and high-concern locations. Multi-floor and multi-zone coverage is standard for commercial buildings and campuses.

Do we receive monthly reports?

Yes. ESG provides routine reports on a schedule that suits your needs. Reports include trend data, threshold performance, notable anomalies, and plain-language interpretation of what the data means for your building and its occupants.

What parameters does ESG monitor?

Core monitoring includes humidity and temperature, airborne particulates (PM2.5/PM10), and CO₂ and common indoor pollutants. Programs are tailored based on building type and goals: commercial buildings often prioritize CO₂ for HVAC efficiency, while residential programs frequently focus on humidity and particulate control.

Does ESG sell HVAC systems or remediation services?

No. ESG is a testing and monitoring company. We install and manage monitoring equipment and provide consultation, but we don't sell HVAC systems, air purifiers, or remediation services. Our independence means our recommendations are based entirely on what the data shows, not on what we profit from selling.

Can monitoring show whether a renovation or HVAC change worked?

Yes, and this is one of the most valuable uses of ongoing monitoring. ESG captures before-and-after trend data following HVAC adjustments, operational changes, cleaning protocol changes, or renovations, giving you documented before-and-after measurements at the monitored locations rather than a best guess.
