# Air Quality & Co2

<figure><img src="/files/VuSQ0zbsiixMoWhgKltQ" alt=""><figcaption></figcaption></figure>

### Overview

The Air Quality and CO2 dashboard tracks two complementary indoor-air metrics: **CO₂ concentration** (a proxy for ventilation effectiveness and occupant alertness) and the **Air Quality Index / TVOC** (volatile organic compounds and general air quality). Both are measured continuously by your sensors and graded against established health thresholds.

Use this dashboard to:

* Monitor ventilation effectiveness and indoor-air health
* Identify rooms where occupants are likely to experience drowsiness or headaches
* Provide evidence for HVAC tuning and ventilation upgrades
* Demonstrate environmental commitment to staff and visitors

### Scoring Bands

#### CO₂ (ppm)

| Band         | Range        | Meaning                                                            |
| ------------ | ------------ | ------------------------------------------------------------------ |
| 🟢 Excellent | < 800 ppm    | Fresh air; full cognitive performance                              |
| 🟡 OK        | 800–1200 ppm | Acceptable; cognitive performance begins to decline above 1000 ppm |
| 🔴 Poor      | ≥ 1200 ppm   | Drowsiness, headaches, reduced concentration                       |

#### Air Quality Index (TVOC)

| Band         | Range | Meaning                                |
| ------------ | ----- | -------------------------------------- |
| 🟢 Excellent | < 0.3 | Clean air                              |
| 🟢 Good      | 0.3–1 | Minor pollutants, no concern           |
| 🟡 OK        | 1–3   | Noticeable; ventilate                  |
| 🟠 Poor      | 3–10  | Headaches and irritation likely        |
| 🔴 Bad       | ≥ 10  | Health risk; immediate action required |

### Dashboard Structure

The dashboard is organised into four tabs:

1. **Monitoring**
2. **Data**
3. **Map**
4. **Floor Heatmap**

A metric switcher toggles every chart between **Air Quality** and **CO₂**.

***

#### Average CO₂ by Resource

<figure><img src="/files/LFwPt4Zny1rkjr4XNocF" alt=""><figcaption></figcaption></figure>

*Horizontal bar chart, ranked.*

Resources ranked by average CO₂ concentration, colour-coded by band.

*Use it to:* find the rooms whose ventilation is most likely overloaded.

#### Average CO₂ by Weekday

<figure><img src="/files/ZfxAoyDOHBByft45fHab" alt=""><figcaption></figcaption></figure>

*Bar chart.*

CO₂ averages per day of the week.

*Use it to:* validate ventilation behaviour at peak attendance days.

### Tab 2 — Data

#### Air Quality Data Table

<figure><img src="/files/cYUK7b6gyhHAWrnct0lI" alt=""><figcaption></figcaption></figure>

*Sortable data grid.*

Minimum, maximum, and average Air Quality Index readings per resource with timestamps.

#### CO₂ Data Table

<figure><img src="/files/dObm0l38LZkKYcOUQX8F" alt=""><figcaption></figcaption></figure>

*Sortable data grid.*

Minimum, maximum, and average CO₂ readings (ppm) per resource.

Both tables support CSV export.

***

### Tab 3 — Map

#### Sensor Map View

<figure><img src="/files/NeMk8UqFnJ9s8NK1dNyJ" alt=""><figcaption></figcaption></figure>

*Interactive geographic map.*

Buildings plotted on a world map, colour-coded by overall air-quality status.

***

### Tab 4 — Floor Heatmap

#### Air Quality Floor Heatmap

<figure><img src="/files/imJgHaPT5zcvfypaAVwy" alt=""><figcaption></figcaption></figure>

*Colour-coded overlay on an interactive 2D floor plan.*

Each monitored resource is shown as a heat point coloured by its current band, allowing you to see at a glance which areas of the floor have ventilation issues.

***

### Filters & Controls

* Building, Floor, Resource, Resource Type
* Date range with presets and custom ranges
* Granularity tabs on trend charts
* Metric switcher: Air Quality / CO₂

***

### Tips

* CO₂ tracks occupancy closely — a room with high CO₂ at low occupancy indicates a real ventilation issue, not a busy room.
* Compare CO₂ peaks against the Reservation Sensor Insights tab in Space Usage to identify specific meetings during which conditions degraded.
