Room Health Insights

Logitech Rally Board 65 contains sensors that measure environmental factors to indicate indoor air quality. For spaces without Rally Board—or any existing technology—you can use Logitech Spot, a standalone sensing device that brings these insights to any room.

These measurements are then made comparable and actionable through Room Health Insights in Sync.

This article helps explain Room Health Insights in greater depth, covering:

Room Health Score

The Room Health Score is a metric to evaluate and compare indoor air quality (IAQ) and comfort, ranging from 100 (excellent) to 1 (poor). It reflects key factors like CO2 levels, temperature, humidity, total volatile organic compounds (tVOC), and particulate matter.

The Room Health Score provides an easy way to assess and compare indoor air quality and environmental conditions across your different spaces and office sites.

This score evaluates air quality and overall room comfort against common industry standard levels based on sensor readings gathered by the device, which include key environmental factors:

Carbon dioxide levels (CO2)
Total volatile organic compounds (tVOC)
Temperature
Relative humidity
Particulate matter (PM2.5 and PM10)

These air quality and environmental measurements are then scored and weighted to produce the Room Health Score.

Monitor air quality and Room Health Scores to make informed decisions that improve workspace conditions.

Carbon Dioxide (CO2)

Carbon dioxide (CO2) is a crucial factor in determining indoor air quality (IAQ). According to Health Canada, elevated CO2 levels inside buildings often indicate insufficient ventilation, which in turn can impact employee health and comfort.

Key Points:

Impact on IAQ: CO2 is primarily generated by human respiration (breathing). Levels above roughly 800 ppm can suggest insufficient ventilation, which could lead to headaches, drowsiness (Apte et. al 2000), and decreased cognitive performance (ASHRAE 2025) .
Recommended Levels: Based on standards and guidelines from multiple different countries put together by Health Canada, CO2 concentrations should be below 1,000 ppm.
Additional Considerations: CO2 must be evaluated alongside other potential contaminants like volatile organic compounds (VOCs) and particulate matter for a comprehensive view of air quality.

By actively monitoring and managing CO2 levels and improving ventilation, organizations may be able to improve the air quality and working environments for their building occupants.

Particulate Matter (PM2.5)

Particulate matter 2.5 (PM2.5) includes fine, inhalable particles with a diameter of 2.5 micrometers or smaller. These particles are often a component of air pollution from cars, industrial plants, roads and construction sites, and can, if inhaled deeply, have adverse health impacts (US EPA). The US EPA has said exposure to PM2.5 has been linked to health problems like respiratory, cardiovascular and chronic obstructive pulmonary (COPD) diseases.

Particulate Matter (PM10)

Particulate matter 10 (PM10) refers to tiny airborne particles that are 10 micrometers or smaller—small enough to be inhaled into the lungs. According to the California Air Resources Board, breathing in too much PM10 can lead to respiratory issues such as reduced lung function, exacerbated asthma, and more (CARB). According to the US Environmental Protection Agency, these particles come from a mix of sources including direct sources like construction sites or fires, and those formed in the air through chemical reactions from emissions released by things like cars, and factories. Measuring PM10 helps us understand air quality and improve working conditions.

Humidity

Humidity is the amount of water vapor in the air. The most common way to measure is relative humidity (RH %), which shows how close the air is to being saturated with water vapor. High humidity can impact human health by making it harder to keep cool, leading to discomfort, respiratory issues, dehydration, fatigue, and increased likelihood of infections (Guarnieri et al.). Low humidity can impact human health by causing respiratory issues, skin problems, discomfort, and also increased likelihood of infections (Reinikainen et al.). A healthy range is typically 40-60% RH, which helps maintain comfort and reduces health risks (Garcia).

To better assess overall perceived comfort in the room, the Swiss Federal Technology Institute recommends pairing humidity measures with temperature.

Temperature

Air temperature affects more than just comfort – it also plays a key role in indoor air quality and has effects on cognitive performance and therefore productivity (Abbasi et al).

For ideal comfort, maintain indoor temperatures within the range of 22-27°C (68-77°F) (Garcia). Temperatures outside this range can lead to dry skin, dehydration, respiratory irritation, impact pre-existing conditions like cardiovascular disease (CDC), and can worsen allergies and asthma symptoms (AAFA).

tVOC

Total volatile organic compounds (tVOC)

Total volatile organic compounds (tVOC) is a measurement of the combined concentration of all volatile organic compounds (VOCs) in the air. VOCs are a large group of carbon-based chemicals that evaporate at room temperature. According to the EPA, they can be emitted from a variety of sources, both indoors and outdoors, including:

Building materials and furnishings (such as paint, carpets, adhesives)
Cleaning products and personal care products (such as air fresheners, perfumes, hairspray)
Combustion sources (such as gas stoves, fireplaces, tobacco smoke)
Outdoor sources (such as vehicle exhaust, industrial emissions)

At high levels of exposure, some VOCs can contribute to headaches, dizziness, nausea, eye irritation, and respiratory problems (US EPA).

Total volatile organic compound index (tVOCInd)

tVOC Index (tVOCInd) measures the relative change in volatile organic compounds in a space compared to the past 24-hours; this helps to detect changes in air quality rather than absolute measures, similar to how we notice new smells when entering a space. tVOCInd ranges from 0 to 500.

tVOCInd above 100 means that there are more VOCs compared to the 24-hour average (usually resulting from activities such as cooking, cleaning, etc.). tVOCInd below 100 means that there are fewer VOCs compared to the average (which could result from opening a window, using an air purifier, etc.).

Total volatile organic compound absolute (tVOCAbs)

tVOC Absolute (tVOCAbs) measures the absolute value of volatile organic compounds in a space in micrograms per cubic meter (μg/m³), which provides precise measurements of volatile compounds present in the air rather than relative changes. tVOCAbs ranges 1-6000 μg/m³.
