Maintaining a healthy, comfortable workplace while reducing energy use has become a priority for many companies. For large organizations that manage multiple buildings, the challenge is bigger: monitoring indoor air quality (IAQ) at scale, in a way that supports occupant well-being, sustainability, and energy efficiency.
A global technology company in Europe faced exactly this challenge. Its campus spans multiple buildings — offices, conference rooms, and common areas — where hundreds of employees spend most of their day. In line with corporate sustainability initiatives, the Facility Management team set out to find a complete IAQ monitoring solution to meet the company’s needs.
“Our organization is committed to make a difference every day for our planet and people: we work to make business in the most sustainable way and to improve workplace conditions for our employees – of course, indoor air is a crucial element to consider.”
The Challenge: Scalable IAQ Across an Entire Campus
The Facility Management team wanted an IAQ monitoring solution that would let them:
- Track air quality over time across every location, to address concerns proactively before they escalate
- Get clear guidance to take fast corrective action
- Improve efficiency and sustainability by optimizing energy consumption
According to the facility manager, a scalable IAQ program providing real-time data and reporting was critical to maintaining and improving occupant health and well-being. With the organization pursuing aggressive sustainability objectives, developing a long-term strategy to optimize energy consumption was an equal priority.
“The team was looking for a system to easily know in real-time how the air quality is within the different organization buildings, and to be able to take quick actions.”
The Solution: A Connected Indoor + Outdoor Monitoring Network
After evaluating the available options, the Facility Management team selected TSI and began with a pilot project across a few office buildings.
Working closely with the TSI Sales Manager, the team installed 14 AirAssure™ IAQ monitors and set up the TSI Link™ Software. Because outdoor conditions affect the indoor environment, they also added several TSI BlueSky™ outdoor air quality monitors beside selected buildings — giving them a complete overview of both indoor and outdoor air quality.
The TSI Solution for Air Monitoring includes:
TSI AirAssure™ IAQ monitor - continuous air quality monitoring with low-cost sensors that track gases, including CO₂ and tVOC, along with particulate pollutants and other key IAQ parameters to help optimize the indoor environment.
TSI BlueSky™ monitor - a lightweight instrument for outdoor air quality monitoring, designed to simultaneously measure PM2.5 and PM10 mass concentrations, temperature, relative humidity, barometric pressure, O₃, CO, CO₂, NO₂, and SO₂.
TSI Link™ platform - the cloud-based software that allows you to remotely manage your equipment and monitor air quality data in real-time, as well as multiple integration options through API.
How It Worked in Practice
The Facility Management team valued being able to manage every device and access all data in one place, at any time. Using TSI Link Monitoring, they appreciated the accessibility of the dashboard and the ability to receive custom alerts in real time whenever a value crossed a set threshold.
“I set up diverse alerts for relative humidity and PM2.5 and monitored the performance over time during our test phase. Besides alert notifications via SMS and email, I found the alert history function very useful to identify trends and make the right decisions.”
The dashboard also made it easy to share IAQ measurements among stakeholders in different locations, improving collaboration and productivity. TSI Link API was the other key component the company leveraged: integrating data with the local building management system (BMS) gave the team the insight and guidance needed to improve efficiency — optimizing the HVAC system, reducing overall energy use, and lowering both costs and carbon footprint.
“Data integration was a key point for us to optimize energy consumption and track progress towards organization sustainability goals.”
The Results
By the end of the pilot, the Facility Management team had achieved gains in two areas that aligned with their original goals:
- Remote, real-time access to air quality data with custom alerts via SMS and email
- A shared dashboard improving collaboration across teams in different locations
- The ability to view and share IAQ conditions internally with stakeholders
- Proactive resolution of IAQ issues, guided by clear data
- Optimized HVAC performance through API integration with the building management system (BMS)
- Lower overall energy use — driving cost savings and a smaller carbon footprint
- Measurable progress toward corporate sustainability goals
For this global technology company, the combination of multiple air quality monitors, TSI Link Monitoring, and API proved to be the right fit - letting facility managers monitor and address issues across many buildings, and act before small problems became big ones.
“With the TSI solution we are now able to understand air quality over time. Thanks to the TSI Link platform and reporting, we have the right level of insights to manage buildings efficiently and protect employees.”
