The short version
- An office heat map colours each desk, room or zone by how much it is used, so busy and empty space shows up at a glance.
- Heat maps can come from booking data, check-ins or occupancy sensors. Each source tells you something different.
- Read them by day of week and by hour, not as one monthly average. Averages hide your peak day.
- Use the result to size the office, move teams, and set anchor days, then check again after every change.
An office heat map shows which parts of your workplace people actually use. Desks, rooms and zones are shaded from cool to hot, so the busy corner and the dead floor are obvious in seconds. It turns a vague feeling (“the fourth floor always seems empty”) into something you can act on.
This guide covers what heat mapping for office space is, where the data comes from, how to read the maps without fooling yourself, and the decisions they should drive.
What is an office heat map?
An office heat map is a visual layer over your floor plan or calendar. Each space gets a colour based on a usage measure, such as how often it was booked, how often someone checked in, or how many hours it was occupied. Light colours mean low use. Strong colours mean high use.
There are two common views:
- Spatial heat maps shade the floor plan itself. They answer “where do people sit and meet?”
- Time heat maps shade a grid of days and hours. They answer “when is the office busy?”
You need both. A floor can look quiet on a monthly spatial map and still run out of desks every Wednesday at 11am.
Where does heat map data come from?
The colours are only as good as the data behind them. Most workplaces use one or more of these sources.
| Source | What it measures | Watch out for |
|---|
| Desk and room bookings | Intent: who planned to use a space | Bookings that nobody turns up for |
| Check-ins | Confirmed arrival at a booked space | Only as good as your check-in habit |
| Occupancy sensors | Physical presence at a desk or in a room | Cost, install time and privacy questions |
| Badge or Wi-Fi data | Building or floor attendance | Rarely precise enough for single desks |
| Walk-round counts | A manual snapshot at set times | Small samples and missed peaks |
Booking data plus check-ins is the most practical starting point for most offices. It needs no hardware and it separates desk utilisation (people who turned up) from demand (people who wanted a space). If you add sensors later, compare the two. The gap between “booked” and “present” is often the most useful number you have.
How do you read an office heat map?
Heat maps are easy to misread. A few habits keep you honest.
- Look at the peak, not the average. An office that averages 40% use across the week may be full on two days. Plan capacity for the busiest normal day.
- Split by day of week. Hybrid offices have a rhythm. Monday and Friday often look nothing like Tuesday to Thursday.
- Split by team and zone. A hot zone may be one team outgrowing its neighbourhood, not a building-wide shortage.
- Check rooms by size. A large meeting room that is always “hot” may be full of two-person calls. Compare booked headcount with room capacity.
- Use enough history. One week can be skewed by holidays or an all-hands. Four to eight weeks gives a steadier picture.
Cold is not always waste. A quiet zone, a
phone booth or a wellbeing room is meant to be lightly used. Judge each space against its purpose before you cut it.
What decisions should a heat map drive?
A heat map is only worth building if it changes something. These are the decisions it supports best.
| What you see | What it usually means | What to try |
|---|
| Whole floors cold every day | More space than you need | Close or sublet the floor, or consolidate before the next break clause |
| One zone always hot | A team has outgrown its area | Move the team or give it a bigger neighbourhood |
| Midweek peaks, empty Fridays | Everyone picks the same days | Set anchor days by team to spread demand |
| Big rooms hot, small rooms cold | Rooms booked for the wrong size of meeting | Add huddle rooms or set capacity rules |
| Booked but not checked in | Ghost bookings and room hoarding | Turn on check-in and auto-release |
| Window desks hot, inner desks cold | People avoid certain spots | Fix the cause: light, noise, screens or temperature |
Make one change at a time and re-run the map a month later. That is how a heat map becomes a feedback loop instead of a one-off report.
How do you start heat mapping your office?
| Step | What to do |
|---|
| 1. Map the space | Get every desk and room onto a digital floor plan with consistent names. |
| 2. Capture use | Turn on booking and check-in so you record both demand and actual use. |
| 3. Wait for data | Collect four to eight weeks before drawing conclusions. |
| 4. Review together | Read the maps by day, hour, team and zone with the people who run the space. |
| 5. Change and re-measure | Agree one or two changes, make them, and measure again. |
If you are sizing a new office, pair the heat map with the office space calculator to turn peak attendance into a desk count.
Heat maps in HybridHero
HybridHero builds usage reporting from desk, room and parking bookings and check-ins, on interactive floor plans that staff already use to book. HybridHero analytics shows utilisation by day of week, team and location, with heat maps on the Professional and Enterprise plans and export to CSV or Excel for your own reporting.
Common questions
What is heat mapping for office space?
It is the practice of shading a floor plan or a day-and-hour grid by how much each space is used. It shows where and when the office is busy, so you can plan space, seating and meeting rooms around real demand.
Do you need sensors for an office heat map?
No. Booking and check-in data is enough to start and needs no hardware. Sensors add physical presence data, which helps if check-in habits are weak or you need very precise occupancy figures.
How often should you review office heat maps?
Monthly is a good rhythm for most offices, plus a fresh look after any change to seating, attendance policy or headcount. Before a lease decision, review at least a full quarter.
Are office heat maps a privacy risk?
They can be if they are used to watch individuals. Report at the level of spaces, zones and teams, tell staff what is measured and why, and keep individual data to the people who need it to run bookings.
