Office environmental monitoring gives facility managers and building tenants the continuous data they need to find the root cause of comfort complaints, understand what's happening in conference rooms during meetings, and make evidence-based decisions about HVAC and capital improvements. Most commercial offices rely on a single thermostat per zone — with no visibility into CO2 levels, solar heat gain patterns, or the real conditions in high-occupancy meeting rooms. Nosy puts wireless sensors throughout the space, tracking temperature, humidity, CO2, and indoor air quality every five minutes, with automated monthly reports that turn raw data into actionable findings.
Temperature complaints are the number one category of facilities tickets in commercial office buildings. Not because the HVAC is broken — it often isn't. But because a single thermostat can't represent what's happening across an open floor plan, a row of private offices with different solar exposures, and a conference room that fills up three times a day.

The south-facing offices are warm in the afternoon. The conference room gets stuffy the moment a meeting starts. The area near the server closet runs warm. The open floor near the exterior wall is cold in winter. Every person in the building has a different experience, and facilities managers have almost no data to work with.
CO2 matters more than most people realize. Research consistently links elevated CO2 to reduced cognitive performance — including slower decision-making, lower scores on concentration tasks, and increased fatigue. A conference room with a dozen people and an hour-long meeting can easily exceed 1,500 ppm — a level where studies show measurable impacts on the ability to think clearly.
For tenants, the situation is more constrained. You may have no control over the building's HVAC at all. What you can do is document what's actually happening in your space — and Nosy installs without drilling, wiring, or landlord permission.

When someone says their office is always hot, that's a complaint. When Nosy shows that the southeast corner runs 4 degrees warmer than the rest of the floor between 2pm and 6pm every day, that's a finding you can act on. Continuous data converts vague complaints into specific, located, time-stamped patterns.
Conference rooms are some of the worst-performing spaces in most office buildings. CO2 rises quickly in a room designed for a fraction of the people in it, and by the end of a two-hour session, the cognitive environment is meaningfully different from when it started. Nosy tracks CO2 and temperature in every monitored room.
Environmental quality data is increasingly part of how employees evaluate their workplace. For tenants, Nosy installs without landlord permission and documents that your office maintains good IAQ. For building managers, it provides the continuous record that supports lease negotiations and capital planning.
Nosy monitors the parameters that matter most in a commercial office environment:
Reveals the actual distribution of heat and cold across the floor — which zones are consistently outside the comfortable range, which track outdoor temperature too closely, and which respond to occupancy and solar gain in predictable patterns. This is the most common source of comfort complaints.
Tracks ventilation effectiveness in proportion to occupancy. In an office, this means you can see how quickly CO2 rises when a conference room fills up, whether open-plan areas are getting adequate air exchange, and whether the HVAC is keeping up through the afternoon. The data connects directly to the cognitive environment your team is working in.
Dry air in winter irritates airways and increases the spread of airborne illnesses. High humidity in summer makes spaces feel warmer than the temperature reading suggests. Nosy tracks relative humidity continuously across every monitored space and flags excursions in both directions.
Captures compounds from cleaning products, new furniture, renovation work, and other sources that cycle through office environments regularly. Spikes after a cleaning crew visits or following a renovation are easy to spot in the data and straightforward to investigate.
Every month, Nosy generates an automated report showing which areas had persistent issues, which had intermittent problems, and how conditions compared against standard thresholds and outdoor weather.
Nosy pilots have been deployed in a range of buildings, and the patterns we see translate directly to office environments. In one commercial building, monitoring found that one side of the floor ran consistently warmer in the afternoon due to solar heat gain — a difference invisible at the thermostat level. In another deployment, zones near high-occupancy areas showed elevated CO2 and temperature during peak hours that returned to normal after the building cleared.
These are typical patterns in any occupied commercial building. The question is whether you can see them. A thermostat tells you what the HVAC is set to deliver. Nosy tells you what your occupants are actually experiencing.
